Special Mic How to raise azalea breeding methods and precautions for rhododendrons
Profile
Rhododendron, also known as Yingshan Hong and Mountain Pomegranate, is an evergreen or ordinary green shrub.According to legend, there are rhododendron birds in ancient times.Rhododendrons are generally blooming in spring, with 2-6 flowers in each cluster. The corolla funnel shapes are red, light red, apricot red, snow green, white, etc. The color is lush and gorgeous.Born in mountain sparse shine or pine forests at an altitude of 500-1200 (-2500) meters, it is a typical acid soil plant in central south and southwestern China.
The whole plant of this species is used for medication: qi and blood circulation, tonifying deficiency, treating internal injury cough, kidney deficiency and deafness, irregular menstruation, rheumatism and other diseases.Because the corolla is bright red, it is a famous flower plant, which has high ornamental value, and is cultivated in the world's parks.Jiangxi, Anhui, and Guizhou in China use rhododendron as the provincial flower. Changsha, Wuxi, Jiujiang, Zhenjiang, Dali, Jiaxing, Ganzhou and other cities are designated as cities with as many as seven or eight cities.In May 1985, azalea was rated as sixth in China's top ten famous flowers.

The ovisical shape of the cricket, up to 1 cm long, densely rough hair; calyx stay.Flower period from April to May, fruit period June-August.
After many years of cultivation of Rhododendron, there are a large number of cultivation varieties. The color of the flowers has more colors, and the shape of the flowers is diverse.
variety
There are more than 900 species of cuckoo all over the world, and the Gardening varieties of cuckoo are all descendants from the original species of Rhododendron (wild resources) through hybridization or buds.For more than a century, there are nearly 10,000 Gardening varieties in the world.China has introduced rhododendron from Japan, Europe, America and other countries since the 1920s and 1930s for cultivation. There are also a small number of new varieties through hybridization, such as "compound color imitation Xijie", "laughing two trees", and "laughing", "Laughing Er Jiao","Dental Petal Purple Cuckoo", "Purple Louchun", "Dwarf Cloud Kim Rhododendron", "Hate the Sky", and the alpine deciduous rhododendrons hybrid "red butterfly", "purple butterfly", "white butterfly" and other new varieties.
Rhododendrons are divided into "five" products: spring Cuckoo, Natson Cuckoo Department, Xishi Cuckoo Department, Dongjuan Department, and Takayama Rhododendron.
spring cuckoo
Refers to the varieties of blooming first and then germination, in the middle, late April, and early May.Hybrid formation forms a unique domestic variety.Because of spring flowers, it is named Chunjuan, and it has continued to this day.
spring cuckoo is native to China, and the Malaysian Peninsula and high mountains in southern Asia are also distributed.Evergreen cuckoo in Sichuan, Yunnan, and Guizhou mountainous areas in China is extremely rich. Fallica rhododendrons are distributed from northeast to South China.Natural community is distributed in high mountains and grows on the slope, which is a semi -shade plant.It was born with cool climate, large air humidity, acidic soil, and barren, but it is not resistant to accumulated water.
Because of the hairs of the leaves, some people are also called "hair cuckoo", because the leaves are also called "big leaf cuckoo".It is a variant and hybrid species of the original species of white flower azalea and splendid cuckoo.10345The flowers are very gorgeous. There are three flowers in one bud. The flower is large and can reach 8 cm in diameter. The corolla is wide.Crimson, purple red, pure white, pink, sprinkle, etc.3-5 or 6-7 new shoots are emitted after flowers, and flower buds began in July to August.Cold resistance, mostly planting. Due to the rapid growth of reproduction, it was used for grafting rootstocks or other new varieties of new varieties.At the same time, in garden greening work, it should be used in color blocks or landscapes.
Cuckoo
spring first has long branches and leaves, and blooms in early May to June, so it is called Xia Juan.Xia Jian's main pro -pro. It is said to be the Yueyue Rhododendron and May Rhododendron.
Its characteristics are: open-minded evergreen shrubs, low plant shapes, strong branches, full of crowns, resistance to pruning, leaf alternate, short interval, dense, leaf length 3-4 cm, 1-2 cm wide, for 1-2 cm, for it, for it, for it, for it, for it, for 1-2 cm, for it, for it, for it, for 1-2 cm, for it, for it, for 1-2 cm.The narrow lanceolate to the inverted lanceolate, thick, dark, and hairy, the leaves of the frost are dark red.From mid-May to June, the flowering period can last until July-August.Corolla is wide, with a caliber of about 5 cm, and 7-8 cm in large.Flower -type single petals, stroke and packet petals, the petals change large, including round, light, soft and hard, wavy and wrinkled.The four seasons are green, and the four seasons are blooming. There are four wonders of yellow, red, white, and purple.It can be potted or planted under the shade conditions.The Xiajuan tree cultivated on the balcony should be trimmed and sorted into spherical shape.Its beautiful and beautiful.The cuckoo tree cultivated in the courtyard should be cut into an umbrella shape, and its shape adds fun.Suitable groups are planted under the forests and rocks that are humid and shelter. The gardens should be planted in trees, forests, streams, pools, and lawn edges.Some categories can make bonsai.
Cuckoo
Dongju is the variant of Japanese Ishiyan cuckoo and many of its hybrid offspring. It was introduced from Japan and was called Dongjuan corresponding to Western Rhododendron.In the spring of the cuckoo period, some places include it into spring Cuckoo.
Main features: the plants are low, the branches are soft, and there are many branches and branches.The leaves are ovate, thin leaves, less hair, tender green, and shiny.There are 3-4 buds of the buds, 1-3 flowers per bud, 4-5 more than a long time, and blooming densely.Corolla funnel, small, caliber 2-4 cm, cylinder length of 2-3 cm, most calyx evolved into corolla, forming 2 sets inner and outer, called double sets and clamps.The color is mostly red, purple, white, pink white, tender yellow, white and green, border, sprinkler and so on.There are 5 stamens, and there are also stamens into high -petal flowers.A few days earlier than the hair cuckoo.From July to August, the old leaves fell, while flower buds were formed.It is not resistant to strong light, can be planted, has strong germination, extremely resistant to trimming, and the flowers, branches, and leaves are slender. It is a good material for the greening of the courtyard to make the color block. It is also an ideal material for making pot flowers.
Cuckoo
Because its flowers are gorgeous, it is popular with people.In particular, the Belgian cuckoo, because it is a variety of Gardening cultures that are hybrid in Europe and the United States, it is called a western cuckoo, also known as the cuckoo.After the introduction of Japan in 1892, the name of the cuckoo variety was translated into Japanese, so China still introduced from Japan to translated from Japan.200-300 species.
The main characteristics of the cuckoo are:
1. Plants are low, half open, grow slowly, evergreen type;
2. The branches are thick and powerful. At that time, the green or red of the branches, related to the color, the red branches opened red flowers, the green branches are white, pink, and pink flowers;
3. The leaves are thick and solid, dark green, the ends of the branches, and the size of the leaves is between the large leaves and the cuckoo in the spring cuckoo.From the changes in the tip of the leaf tip, the color of the flowers can be slightly known, such as the tip white and transparent, the color of its color is white or other light colors, the tip is red, and the flower is red.Among them, the four seasons rhododendron can be regulated and cultivated, and the flowering period can be advanced to New Year's Day and the spring Festival.The flower type is large, with a diameter of 6-8 cm and a maximum of more than 10 cm.Most of the decent petals, petals and colors are changing, and the value of ornamental is extremely high.From the perspective of many years of local cultivation, the adaptability and disease resistance of Xishi are relatively poor.Only potted plants should be properly shaded in summer and warm in winter.The cuckoo introduced from Dandong in 1984 is mainly Belgian azalea. The current main breeds include 7 species of the Belgian Rhododendron series, 3 varieties of Western Rhododendron series, 4 burgers, 3 Bai Jiaren, four seas wavesThere are 5 series, 6 five treasures series, 4 Crown series, a total of 32 varieties.The main representative species are: five treasures (Wuxi: Jinpao), Crown (Dandong: icing on the cake), Four Sea Wave (Wuxi: Tian Nu dance).It is an ideal material for making pot flowers.
Takayama Cuckoo
Alpine azalea, is a cuckooing cheese evergreen shrub or a small tree plant.
The morphological characteristics of alpine cuckoo: evergreen shrubs or small trees, 1-3 meters height, thick branches, leaf clumps, thick leather, 6-12 cm long, 2-5 cm wide, blooming from April to May, from April to May, flowersThe flower type is mainly packed and heavy petals, and there are also a small amount of single petals, which is about 1 month.The color is white, pink, light red, pink, yellow, etc.Generally grows in mountains and wilds at an altitude of 600-800 meters, and has strong adaptability. After artificial domestication and cultivation, it is expected to become a common green view of garden green space.
A brief method of identifying Dongjuan, hair cuckoo, Xishu, and Xiajuan:
1. The same point:
All four kinds of azaleas are deciduous azaleas; they are resistant to cold and heat; soil is fertile and acidic, loose and transparent.
2. Different points:
1. There are different sources: Dongjuan and Natsuma belong to Japan Rhododendron; Maojuan belongs to China Rhododendron; West Cuckoo belongs to Western Rhododendron.
21223Small, slender branches and leaves, dense branches, full of crown and neat.
3The leaf and broad -leaved are divided into;
4. flowers: The smallest flower of the cuckoo, blooming in April, dense flowers, or merging of the petals by the calyxic petals, there are fewer petals, more colors;The color is generally red, purple, pink white and compound color; the beauty of the cuckoo is the most cuckoo, the flower period is April to May;
5. Cultivation and breeding: Cuckoo is delicate.Cuttings need to be raised for 2 months, and the survival rate is low, so the grafting method is generally breed.The other three types of cuttings are fast and the survival rate is high, and potted or ground planting can be available.
Suitable place
Rhododendron is suitable for growing under the light with small light intensity. Generally speaking, indoor unsuitable rhododendron growth.If you want to raise it, it is best to cultivate it in the living room or on the balcony, try not to put it in the bedroom.
Effectiveness and role
Viewing value
Rhododendron is leafy, beautiful, strong, strong, resistant to pruning, and strange roots. It is an excellent bonsai material.The gardens are most suitable for planting in the forest margin, stream, side of the pool, and beside rocks.Rhododendron is also a good material for flower fences. The hair cuckoo can also be cultivated into various forms.The cuckoo special garden is very distinctive.Even when the flowers bloom in the flower season, even if the cuckoo always gives people a lively and noisy feeling, instead of the flower season, the dark green leaves are also suitable for planting in the garden as a low wall or barrier.
Medicinal value
Gen (Rhododendron root): sour, sweet, warm.Activating blood, relieving pain, expelling wind, analgesic.It is used for vomiting and blood, irregular menstruation, irregular menstruation, leakage, rheumatic pain, and bruises.Leaf (Rhododendron leaf): acid, flat.Clear heat and detoxify, stop bleeding.Used for bloated scabies, trauma bleeding, addiction.flowers (cuckoo): sour, sweet, warm.Activating blood, regulating menstruation, and removing rheumatism.Used for irregular menstruation, closed menstruation, crash, falling damage, rheumatic pain, vomiting blood, and blood.
[Disposal] Dumb dumb: flowers and fruits treat irregular menstruation, amenorrhea, bruises, rheumatism, vomiting blood, and blood; root treatment of rheumatoid arthritis, bruises, leakage, intestinal wind, amenorrhea, amenorrhea, amenorrhea, amenorrheaEssence
Economic value
Some leaves can be used as medicine or extract aroma oil, some flowers are edible, bark and leaf can be made of grilled glue, and wood can be used as crafts.The root of Gaoshan Rhododendron is well -developed and is a very good soil and water conservation plant.
Breeding method
illumination
In the early spring season, the azaleas should be placed outdoors in April and May, and the back of the wind to the sun should be placed. Because the sunlight is still soft in spring, it can be given to the sunlight for a long time.
After the summer, it should be placed in a place where there is shade, and it should not be exposed to the sun and keeps ventilated.In the case of high temperature, you can spray water on the rhododendron branches and leaves appropriately, and buy a shade net to avoid direct sunlight.
At noon in the early autumn, you should pay attention to Shading at noon, so as not to let the azalea stay in the direct sunlight for too long, and you can accept light at other times.You can place the azalea in the sun in late autumn, and you can accept long -term light.
At the end of the autumn, in October and November, the azalea was moved into the room, paying attention to keeping the air circulation.In winter, you can place the azalea in a place where the indoor sun is sufficient. Pay attention to maintaining the indoor temperature. It is advisable to be ten degrees.Excessive high will accelerate the metabolic activities of the cuckoo, consume nutrients, and affect the development of the coming year.Too low will cause the rhododendron's leaves to become yellow, stop growth or even die.
Humidity/watering
Rhododendron requirements for the dry and humidity of the soil are moist and not wet.In general in spring and autumn, the rhododendrons planted in the open field can be poured once every 2-3 days. In the hot summer, it can be poured at least once a day.Daily watering, do not use alkaline water. When watering, you should also pay attention to the water temperature should not be too cold. Especially in the hot summer, watering through cold water can cause the soil temperature to suddenly reduce, affect the root absorption of the root system, and interfere with the physiological balance of the plant.
planting and pouring the water once after planting and changing the soil, the root system is fully exposed to the soil to survive and grow.Pay attention to watering during the growth period. Starting from March, the amount of watering gradually increases, especially in summer that cannot be dehydrated, and often keeps pot soil moist, but do not accumulate water. Reduce watering after September.Dry it again.
temperature
Moving out of the greenhouse in mid -April, first placed in the back of the back wind, shaded in summer, or placed under the shade under the tree to avoid direct sunlight.The suitable temperature is 15-25 C, and the maximum temperature is 32 C.In mid-October, it began to move into the room. It was placed in the sun in winter, and the room temperature was maintained at 5-10 C. The minimum temperature should not be lower than 5 C, otherwise it would stop growing.
soil
Rhododendron is a plant of Xixi. The direct radiation of the sun is not good for it, so it is best to choose a cuckoo special garden in a place where there is a shadow shadow, or when you do greening design, consider this.The garden is configured with trees.Rhododendron's well -drained acidic soil, but because various specialty parks and landscapes must be used as roads and pavement with cement, so that the soil plate of the rhododendron planting places is severely alkaline. ThereforeThe quantity peat soil.
The north of the Yangtze River is viewed with potted plants.The pot soil is used for rotten leaf soil, sand soil, and the same soil (7: 2: 1).Generally, it will be pelvis or change soil in March.The south of the Yangtze River is mainly planting and planting before spring buds. The location should be selected in ventilation and semi -overcast places. The soil requires loose and fertile, rich in humus, and it is advisable to use acidic sandy loam soil and should not accumulate water.Otherwise, it is not conducive to the normal growth of the cuckoo.After planting, it is solid and watering.
Fertilize
In the late winter and early spring, it is best to apply some organic Fertilizers to the Rhododendron Garden.After the flowering flowers from April to May, the plants consumed a large amount of nutrients during the flowering period. As the leaf buds germinated, the new shoots were long, and they could chase Fertilizer every 15 days.After entering, most of the branches have stopped growing. At this time, it is at the high temperature season, and the physiological activity weakens, and you can stop top topical.After the autumn, the climate is getting cooler, and there are autumn rain, and the temperature and humidity should be growing in the cuckoo. At this time, you can do the last top top chaoculation. Generally, fertilization should not be applied after winter.
Reasonable fertilization is the key to raising azaleas. Try to fertilize and avoid thick Fertilizer. In the spring and autumn growth season, apply thin cake Fertilizer water every 10 days. It can be fermented with rice water, peel, and vegetable leaves.Some phosphorus and potassium Fertilizers can also be added in autumn. It can be made of fish, chicken internal organs and meat washing water and rice water.In addition to the above -mentioned homemade Fertilizers, you can also buy some household Fertilizers to use it, but remember to "thin" Fertilizer.Apply dry Fertilizer (a small amount) before winter.In addition, do not directly use tap water whether water or fertilization, should be used directly (add sulfate or vinegar), and then use it when the pH value reaches about 6.
prune
Pruning the entire pruning is an important measure in daily maintenance and management. It can regulate growth and development, so as to make growth strong.Daily trimming requires a small number of diseased branches, weak old branches, and deleting some dense branches in combination with the crown form, which increases ventilation and light transmission, which is conducive to plant growth.The Rhododendron Garden must be checked frequently. If there are dead branches and sick branches, it should be cleared in time to reduce the spread of diseases and insect pests in the cuckoo.
The buds should be picked in time to concentrate the nutrients and promote the flowers.Pruning branches are generally carried out in spring and autumn. Cutting cross branches, dense branches, overlapping branches, and weak branches, and removing residual flowers in time.Plastic surgery is generally modified by natural tree shapes, as desired, because of the tree shape.
Flowering period
If you want to see flowers in the spring Festival, you can move the pot flower to the greenhouse at the greenhouse at 20 C in the greenhouse at 20 C in January or before the spring Festival. Other management is normal, and the flowers can be considered during the spring Festival.If you want to see the flowers "May 1st", you can move the basin to the room below 5 C before the early spring sprouts, and move to the greenhouse of 20 C on April 10th. On April 20, the "May 1" can be seen.Therefore, the temperature can be adjusted to the flowering period, and it will be opened at four o'clock. In addition, the plant that is cut after flowering can bloom in late October; if the growth season is trimmed, the flowering period can be delayed for about 40 days; if the cuttings are trimmed, the flowering period can be available.Delayed until the following year to February.Therefore, the trimming of different periods also affects the morning or evening of the flowering period.
Frequently problem handling
Breeding method
The breeding of azalea can be used with cuttings, grafting, pressing, division, and sowing. Among them, the use of cuttings is the most common and the breeding volume is the largest.For grafting, sowing is mainly used for cultivation varieties.
Cuttings
This method is the most widely used. The advantage is that the operation is simple, the survival rate is high, the growth is rapid, and the traits are stable.
Time, the cuckoo from late May to early June, the hair cuckoo was from the beginning and mid -June, and the Chunjuan and Xiajuan were in mid -to -late June. At this time, the branches were old and tender, and the climate was warm and humid.
Cutties, take the branches of rigidized wood, bring down, repair the hair head, cut off the lower leaves, keep the top 3 to 5 leaves, and the moisturizing to be inserted;
Cutting management, cutting matrix can be used in orchid soil, alpine humus soil, yellow heart soil, vermiculite, etc. The depth of the cuttings should be 1/3 to 1/2 of the spikes. After the cuttings are completedProper shade, always keeps cutting bases and humidity in one month. Maojuan, Chunjuan, and Xiajuan can take root in about a month, and the cuckoo takes about 60 days to 70 days.
The cuttings are breed, and the cuttings pot is better than a 20 -cm caliber. Because of its good air permeability, it is easy to take root.The cultivation soil mixed with 20%humus garden soil, 40%horse dung, and 40%of river sand is the matrix.The time of cuttings is the best in spring (May) and autumn (October). At this time, the temperature is between 20-25 C and the most suitable cuttings.When cutting, choose a strong and developed branches of the year as a cuttings for cutting, and press the knife with a very profitable daughter-in-law; cut 6-10 cm with joints.Fitons.Buy 1 vitamin B12 injection. After opening, dip the cutting cutting in the medicinal solution and take it out for a while to cut it.Before inserting, you should use the watering pot to train the soil tide in the basin the day before, but you should not spray too much. By the next day, you are mocking, which is most suitable for cuttings.The depth of insertion is 3-4 cm.When inserting, first use chopsticks to save a hole in the soil, and then insert the cuttings. Use your hands to compact the soldiers, make the pot soil fully contact with the cuttings, and then pour water through the water.After inserting it, the Flower pot is best covered with a plastic bag, the bag mouth is tied with a strap, and it is opened when watering.The cuttings of the cuttings should be placed in a direct sun -free place. The cuttings are sprayed with water every day within 10 days. Except for rainy days, it can be sprayed once in cloudy days.It should not be too much.After 10 days, you still need to pay attention to keeping the soil moist.It will be shaded within 4-5 weeks, and it can gradually allow it to accept some sunlight until the bud.It usually takes about 2 months to take root.After that, it only needs to be shaded for 2-3 hours at noon, and the rest of the time can be allowed to receive light to facilitate the manufacture of nutrients in its photosynthesis.
Press
Generally use high -tech strokes.Rhododendron press is often performed between April-May.The specific operation method is: first take 2-3 years of robust branches on the mother plant of the cuckoo in the potted plantation, and cut a rotary Skin of about 1 cm wide at 10-12 cm at the top of the branch.The sieve Tube is gently peeled off and cuts off the channels of the leaf to create organic substances to be transported down to gather it to accelerate the division of cells and form a tumor -like protrusion, germinating the root buds.Then use a rectangular plastic film to loosely roll two laps, tighten the fine rope at 2-3 cm at the lower end of the ring incision, and open the upper end of the plastic film to open into a horn bag, and then fill the humid soil and a little moss. ThenTie the upper mouth of the bag tightly, and move the Flower pot to the place where the sun is not shining directly for daily management.When watering, spray water at the leaves, let the water flow down the branches, and slowly seep into the bag, keep the soil in the bag often wet, so as to heal the wound on the branches, so that it will make new roots.After about 3-4 months, the roots must be cut to 2-3 cm.
grafting
You can get a lot of spikes, multi -variety, fast growth, good plant shape, and high survival rate.
Time, from May to June, use tender shoots or abdominal connection methods;
The rootstock, a 2 -year -old hair cuckoo, requires the new shoots and scion to be proper.
Scion, cut 3 cm to 4 cm long tender shoots on the cuckooing plant, remove the lower leaves, retain 3 to 4 small leaves at the end, cut into wedge -shaped bases at the base, and cut the surface of about 0.5 cm in length of about 0.5 cm.To 1.0 cm.5 Grafting Management, cut off from 2 cm to 3 cm from the new shoots of Maojuan, remove the leaves of this part, cut 1 cm longitudinal, insert into the spike wedge -shaped end, align the cortex, use a plastic film with a co -joints with a plastic bag, a positive plastic bagMoisturize the mouth; place it under the shade, avoid direct sunlight and exposure.After 7 days after receiving, as long as there are small water beads in the bag and the scion does not wither, it is possible to survive; go to the bag for 2 months, and then unlock the band.
sowing
Most of the rhododendrons can be selected strongly, and only severe petals are not strong.The maturity of the general seeds from October-January each year, when the peel turns from green to yellow to brown, the top of the fruit is cracked, and the seeds begin to scatter. At this time, it must be harvested at any time.The last cracking brown is picked down, and the room is placed in a good ventilated place to cool down, causing it naturally, then remove impurities such as the fruit shell, put it in a paper bag or cloth bag, and store it in a shade.If there are greenhouse conditions, the sprout rate is high.Generally, the sowing time is made of pots, because the seeds are small, wash the pots inside and outside, put them in the sun, sterilize and disinfect, the soil is sterilized and disinfected.Wet and fertile is rich in organic acidic soil.In order to make the seedlings evenly, the seeds are mixed with some fine soil, sprinkled into the pot and covered with a thin layer of thin soil.Improve the temperature in the pot.After the unearthed seedlings are unearthed, the coverage time is gradually reduced. Due to the small seedlings, pay attention to the temperature, the temperature changes, the sudden changes, and the light of the light.The seedlings grow very slowly. It only grows 2-3 of the leaves from May-June. At this time, the first transplanting in the room is 2-3 cm, and the seedlings are 2-3 cm (about November).Large seedlings are transplanted in one of 10 cm pots and three plants are planted in small seedlings.Water and light water with a fine watering pot.After sowing, the flower room was released the next spring and was maintained under the shade.In the 13.3 cm pot in June, the plants were 20 cm high in the third year, and there were several branches and flower buds. In the 16.7 cm pot, the pot was changed year by year according to the size of the plant.
Prevention and treatment of pests and insect pests
Rhododendron's disease mainly includes root rot, brown spot disease, dark spots, leaf blight, iron deficiency and yellowing disease.After the rhododendron has a root disease, it grows weak, the leaves are withered, dry, and water -stained brown fields appear on the surface of the root system. Severe soft rot, gradually rotten and peel, and the wooden part becomes black.This disease is most likely to occur in environment with high temperature and high humidity.The prevention and control method is to strictly disinfect 10 soil before turning the basin, and maintain soil sulfur and moisturizing, so that it has good permeability to avoid stagnant water.If plants are found to be sick, deal with the diseased plants and pot soil in time.During the treatment, you can use 0.1%potassium permanganate aquatic solution or 2%sulfate gonorrhea strain, and then rinse it with water.Use 70%of the wettable powder of Tabetin and 1000 times water to make a solution to spray the pot soil to cure it.
The common pests of cuckoo are: red spiders, military insects, aphids, and short snails.The red spider is small, but it is serious to the cuckoo.The high -rise buildings are the most prone to such insect pests.The prevention and control method is manual killing.Pharmaceuticals can be sprayed with 5 degrees of stone sulfur, and can also be used to soak the liquid juice with various portions of walnuts, chyo leaves, and green crickets.It is also a good way.
Brown spot
It is a major disease of azalea.At the beginning of the disease, a small brown spots appeared on the leaves, and gradually developed into irregular large spots. Many black or gray -brown dots were produced on the lesions, which turned yellow and falling off.EssenceThis disease often occurs when the humidity of the plum rainy season is large.
The treatment method is to pay attention to the ventilation and light transmission of the plant, not to make the humidity too large, and add Organic fertilizer, phosphorus, phosphorus, potassium mixed Fertilizer, and enhance the resistance and growth capacity of plants.If the diseased leaves are found, it should be removed in time and concentrated.In the early stage of the disease, sprayed 0.5%Bordeaux or 0.4 waves of gwaii stone sulfur, and added 4%Flour to increase adhesion.Lotomia and dark spots can also be treated in the same way.
Yellow disease
iron -deficient and yellowing diseases often occur in areas where soil is alkaline. When the condition is mild, only the plant is late green. In severe cases, the leaf tissue can all turn yellow and the edges of the leaves are scorched.At the time of the onset, the blades of the top of the plant are the most obvious, and they are generally caused by the internal iron deficiency.
The prevention method is to change the iron deficiency in the soil and reduce soil alkali.Added Organic fertilizer to transform the sticky soil.For iron deficiency plants, spray O.2%one 0.3%sulfate sulfate.You can also use chopsticks around the plant to poke a few holes with a few depth of 15 cm deep, and use a 1:30 sulfate sulfate solution to slowly inject the holes to increase the soil acidity and reduce alkaline.
Gartic disease
The onset and the environmental conditions are similar to brown spot disease, and similar methods can be used in prevention and treatment.
Arms
The adults of the army are small and flat, about 4 mm long, and black. It is the most harmful pest to evergreen rhododendrons. It often hurts the leaf liquid behind the leaves.The leaves fall off, causing weak trees, affecting growth and flowering.This worm is likely to occur in the greenhouse.
The maintenance method is mainly to spray and kill with drugs.It can be used for prevention and treatment with 90%of the original drugs of 90%of the original medicine of the enemy, 1500 times liquid of 1500 times liquid liquid or 50%killing loose emulsion 1000-1500 times solution.
aphid
The main harm to the young branches and leaves of azalea can make the leaves lose green. For those who are serious, the leaves are curled up, hard and crispy, cannot absorb nutrients, and affect flowering.
The prevention method is to pay special attention to aphids during the winter. After winter, you can spray a 5 -degree stone sulfur agent on the plants to eliminate overwinter eggs, shovel weeds near flowers, and eliminate the source of insects.During the hazards of aphids, 40%of the fruit or oxidation fruit plus 1200 times water is made to make solutions for continuous spraying, and it can be visible in 3-4 times.
It is one of the important pests in azalea. It is often stabbing juice near the main vein of the back of the blade, causing the leaves to form a lot of oil -stained fields, and finally causes the leaves to fall off.This worm is ovate, with a body length of about 0.3 mm, flat body, red, dark red, and wood red. There are irregular black spots on the back of the body.This worm is most common when it is hot in summer, and the amount of rainfall decreases.The prevention and control method is to spray a 500 -flocking water -bloating water agent 500 times in mid -late and late October and early spring in March in March.
Solution to drop leaves
1. Environmental discomfort fallen leaves
Most of the azaleas sold in the market are cultivated in the greenhouse. After the purchase, the natural environment of the family cannot be adapted, and there are often fallen leaves or even death.The same problems will occur in the cuckoo cultivated in different places.
[Solution] The newly purchased Rhododendron should try to keep the air humidity, appropriate shade, keep the pot soil moist, need air circulation but not cold wind, and not rush to change the soil and fertilize, try to make it safe to adapt to adaptation to adapt to it safelyExpect.Full light should be given in winter. In the indoor maintenance, try to set up the south window as much as possible, and the ambient temperature cannot be lower than 5 degrees.Don't change the place at will to avoid changes in temperature drama.Don't put it in the more dirty air.
2. Potting soil discomfort
[Solution] The cultivation soil must be used with good ventilation and rich humus. The pH value is 5.5 to 6.5.Usually apply some alum Fertilizer water, or add a little sulfate to the water.If the use of alkaline soil will cause the leaves to fall off.
3. Fatty and harmful leaves
Rhododendrons do not like big Fertilizer. The most volatile deviation of the family planted azalea is not the lack of Fertilizer of the plant, but too much fertilization.Once raw Fertilizer and thick Fertilizer are used, scorch leaves will cause fallen leaves.The so -called Fertilizer.
[Solution] Add an appropriate amount of mild release Fertilizer to the basin soil when changing the basin (organic film envelope for Fertilizers, and the Fertilizer is slowly released by the supply of plant nutrition through the penetration of the membrane).EssenceThis Fertilizer is often used in the production of Gardening, which is too troubled and clean.Once the family planting is found, the Fertilizer should be performed immediately, and the Fertilizer in the soil should be watered. After watering, it will be moved to the ventilation place for maintenance. Some need to rinse twice. After about half a year, we can gradually return to normal growth.
4. During the leaves of waterlogging
The cuckoo root is slender, such as poorly permeability or too much watering of the pot soil, and too much watering for a long time. In addition, the ventilation is not good. The root system is damaged and rotten, causing fallen leaves.
5. Dry and harmful leaves
If you are not careful, forget to water or water for a long time, leaves will also appear.Be sure to pay attention to "pouring through", and usually spray water from the leaves and its surroundings to improve the environmental humidity.
6. sunlight and Great Wind
Rhododendron is happy but fear of scorching.summer is placed under the scorching sun, and spring (especially early spring) and autumn at the air outlet will cause a lot of leaves.
[Solution] Pay attention to the cultivation of azalea in the morning and evening with the sun and the wind.
7. Physiological leaves
It is too dense to bloom, and the old leaves will also be taken off when the nutrition is not available in time or pumping the new leaves. It is normal. It can be solved by normal soil replacement.Family cuckoo generally blooms and sprouts new leaves in April-June, and old leaves will fall off.After flowering, branches and plastic surgery, cut off dense branches, cross branches, weak branches, drooping branches, long branches and pests and insect branches.
precautions
1. Rhododendron is a typical acidic soil flower. To prevent yellowing, 0.2 % sulfate should be applied every 20 days.If the leaf color is yellow, spray it with 0.2 % sulfate water water directly to the leaf surface to make the leaves turn from yellow.
2. Family flowers, if you want to make the cuckoo bloom in the spring Festival, you can use the method of breaking its dormant period.spring cuckoo, which is about to be pregnant, moved into the room in mid -December to keep the room temperature above 5 C. Apply a thin Fertilizer every 10 to 15 days.In order to increase humidity, it can bloom before the spring Festival.
3. MaiGoo editor reminds: Rhododendron grows slowly. Generally, it can be changed to pots every two years.Fill in the new cultivation soil when changing the pot.Generally, eight copies (peat soil), 1 part of the garden soil, and a mixed cultivation soil are prepared, and a small amount of (about 50 grams per pot) rotten oil residue or chicken feces for bottom Fertilizer.
4. During the growth period, the stems and branches are often easily germinated with indefinite buds. It should be erased in time to avoid disturbing the plant type.After pregnancy, if there are too many flower buds, you should remove the excess flower buds. Each flower branch will only leave one flower bud. By the way, the nutrients should be concentrated to promote the flowers.After flowering, the residual flowers are not easy to fall off. In order to reduce nutrient consumption, the residual flowers should be removed in time to promote the germination of the new buds.
