Suitable place
Many people like to make the home more elegant and stylish, and also hope to create a fresh atmosphere of nature. Brazilus is a good choice. It is suitable, and it is also good in the fresh air effect.However, it should be noted that if Brazilian wood strains are too large, it is best not to put it in the bedroom. Brazilian wood will not optical effects at night, cannot release oxygen, and absorb oxygen like people. Putting in the bedroom will cause the bedroom to cause the bedroom in the bedroom. Insufficient oxygen and so on.
Effectiveness and role
Viewing value
The Brazilian iron trunk is thick, the leaves are sword -shaped, green and bright, and full of vitality. It is known as "a new star of leaf -seeing plants". It is a very popular indoor large potted flower and wood, especially in a wide living room, study room, and living room. The style is elegant, rustic, and has the mood of the southern country.It is a new generation of indoor leaf -viewing plants with beautiful plant -shaped, regular, and world -renowned interior.
Economic value
Barbari iron and its same varieties are the same. Because they are particularly resistant to shade, they are high -end leaf -viewing plants in the indoor. They will grow vigorously under the conditions of high temperature and humidity and sufficient sunlight. Stem cuttings can be reproduced throughout the year.The seedlings required for factory production can be obtained by organizational training.When cultivating in general families, the mature stems of potted plants can be cut into sections. The lower part can be buried in the matrix of perlite, vermiculite, and cog slag. It is very easy to take root and live.The Brazilian iron root system is stout and developed, and it is most likely to be polluted without pollution.
There are soil cultivation of Brazilian iron, which can be transferred to pollution -free cultivation at any time. There is no need to recover. It can immediately enter the hotel, restaurant, shopping malls, and office buildings.Pollution -free cultivation of Brazilian iron grows in the air -conditioned room, which is even more satisfactory.The indoor greening decoration of modern buildings, various foreign green design companies are preferred by Brazilian iron.It is foreseeable that Brazilian Railway will enter the market as the most competitive indoor plant and be favored by people from all walks of life.
Purify the air
Brazilian wood leaves and roots can absorb vicrone, toluene, metronin, benzene, and formaldehyde, and decompose them into harmless substances, suitable for indoor air purification.
Breeding method
illumination
Brazil's wood is very wide in adaptation to light, and it is durable.However, long -term placed in the room that is too shaded in the room can cause the leaves to yellow and make the leaf patterns fade.spring, autumn, and winter should be more sunny, especially in winter.In the bright part of the room, it can be placed all year round.If you must be placed in a dark indoors to watch, after watching 15-30 days, you must light up in a suitable place for a period of time, and then place it indoors to watch it.Brazil is afraid of direct light. In the summer, pay attention to prevent direct sunlight.In summer, it should be kept on Outdoor. Pay attention to the Shading of about 50 % of the Shading material to prevent the sun burns the leaves and affect the ornamental effect.
Humidity/watering
Brazilian wood is more drought -resistant, but inadequate watering and too much potting soil will grow poorly.The growth season should be kept moist, especially in the strong and growing summer.The potted plants of the family should "see dry and wet", that is, the surface layer of the pot soil is not poured, and it is poured through.After the autumn, the amount of watering should be gradually reduced, and watering should be controlled in winter dormant.Too much watering can cause root rot.
During the cultivation and maintenance process, a certain air humidity should be maintained. If the air is dry, it should often spray water on the leaves to prevent the tip of the leaves from drying and curling, and make the leaves clean and bright.During the growth period, if the leaves are sprayed 2 to 3 times a day, the leaves are well stretched.
Keep the water quality clean during the training period. Watering L to 2 times a week, the water is not easy to prevent the tree from rotting.At high temperature in summer, you can use the spray method to increase the humidity of the air and spray water on the leaves to keep moist.
temperature
The temperature required by Brazilian wood is good at 20-30 C. It can pass winter above 10 C or more. When the temperature is too low, it will stop growing.
As long as the temperature and other conditions of Brazilian wood are suitable, Brazilian wood can grow throughout the year.In high temperatures in summer, it is necessary to cover the yin appropriately. In winter, it should not be lower than 5 C, but it is best to make it dormant in winter. The dormant temperature is 13 C, the temperature is too low, and the leaf tip and leaf margin will appear.
soil
Potted Brazilian wood on the market mostly uses fine sand. It is adopted by the elderly to make the plants full of root. Long -term use is not conducive to plant growth.To thrive plants, you must change into peat soil in installments.The soil requirements are not strict. It is most suitable for loose, well -drained, rich in humus, acidic, and acidic (pH5.5-6.0).4 parts of corruption, 3 parts of garden soil, 2 parts of river sand (or perlite), and 1 part of Organic fertilizer are made into cultivation soil.
Fertilize
Potted Brazilian wood should not be too large, and it should grow slowly to maintain a proper height.Therefore, fertilization should be applied less.During the growth period, thin liquid Fertilizer can be used every 15 to 30 days, which can promote the bright leaves.The variety of spots should be applied less or Fertilizer with high nitrogen content, so as to avoid fading the color of the leaf patterns.Generally, 20 % to 25 % of cake Fertilizer can be applied to cooked, or 0.2 % 0.3 % of the two ammonium phosphate plus 0.3 % to O.5 % potassium nitrate is performed.The water solution is sprayed with leaf surface.
In the growth period, Brazilian wood should be appropriately pursued by the root, spraying the leaves with 100 times diluted nutritional liquid, once every half a month.After several years of wood cultivation in Brazil, the plants are too tall or the lower leaves of the stems fall off. When the tree shape is poor, it should be trimmed.Change pots or soil every year.In addition, excessive ventilation, drought, irregular watering and excessive fertilization can cause the leaf tip to dry.
Brazil's mild, humid, and semi -yin slightly acidic environment.The growth temperature is 20-30 C, but it should not be lower than 10 C, and the best temperature is above 15 C.There is a certain degree of negative, but avoid direct sunlight.From October to April, adequate sunlight should be given.Keeping the pot soil is fully moist during the strong growth period, but avoid water.In the dormant period of winter, the amount of watering needs to be controlled so that the potting soil is dry.Keep 70%during growth.80%of the air is relative humidity.When the humidity is low, spray water on the plants and the surrounding environment to keep moist.When the air is too dry, the leaf edge and the leaf tip of the new leaves are easily burnt.Good drainage, well -known loams rich in humus.Can be mixed with rural soil, corrupt leaf soil, peat soil, bran ash, or perlite to be mixed with a ratio of 1: 1: 1, and add cake Fertilizer or rotten cow dung and chicken manure as base Fertilizer.Periodic Fertilizer is applied at 10.5 days during the growth period.From early September, the stoppage of nitrogen fertilizer is stopped, and 2 to 3 times of phosphorus and Potassium fertilizer is applied every 30 days, which can fully mature plant tissue and improve the cold resistance of wintering.
Brazilian wooden stems are upright, and the leaves are often densely dense on the top of the stem.After the plant is tall, it will cause the stem base to be empty and bald, which will affect the ornamental effect.Because Brazilian wood is resistant to pruning and strong sprouting power, it can be cut off too high.The buds below the cutting mouth will germinate into new branches and form a low and plump plant type. At the same time, 1-5 new buds grow below the cutting mouth.
Hydroponic technology
The hydroponic of Brazilian wood is based on the water, and the Brazilian wooden stump is directly planted in the pot (container) of the water (container), or when the Brazilian wood grows, the required nutrient solution is used for the greening decoration of the living room.Brazil's wood hydroponic nutritional solution is preferably acidic nutrients rich in nitrate nitrogen. Among them, each liter of nutrient solution contains 4 calcium nitrate 1.069, potassium dihydrogen phosphate 0.1369, potassium nitrate 0.3039, potassium sulfate 0.2619, and 7 magnesium sulfate sulfate.0.4929.Saw the Brazilian wooden pillar trunk into a stem section of 10-20cm. In order to prevent water evaporation, the upper end should be painted with wax protection, and then placed in the pelvis of water.Fully suw to spray 0.1%potassium dihydrogen phosphate aquatic solution on the seedlings of seedlings. It can soon produce new roots in the lower part, germinate branches at the upper end, and then manage normally under sufficient light.When using a large cultivation substrate such as grain grains, it is necessary to add 1.2 times a diluted nutrient solution per week.When the surface of the ceramic grain is found like a creamy material, it indicates that the pottery is attached to the salt, and the cultivation substrate can be cleaned at this time.Rinse the alkaline soil with 10 times diluted rice vinegar once, and repeatedly washed the substrate 2 to 3 times in the pouring solution, and then poured it out together with the nutrient solution to replace the newly prepared nutrient solution.Double the raw solution, when poured in the future, use a nutrient solution for 5 to 10 times.
Usually be maintained, and use the diluted rice vinegar once every 30 days to avoid rinse of large water. The nutrient solution can be replaced once every 6 to 12 months.In the first year of hydroponics, the most strong growth of the first year. With the gradual consumption of nutrients in the second year, the original solid stem section gradually became softer, bark was loose, and the leaves were green to yellow.Growing and watching.
For the delayed and updated Brazilian wood band leaf branches, water can also be performed. After inserting into the water, the new roots are germinated in about 30 days, and new leaves are grown.The root system of Brazilian wood is slightly yellow or orange. If it is placed in a transparent glass container, the orange -yellow root system is reflected with the leaves above the ground, which is quite ornamental.
Frequently problem handling
Breeding method
Multiple cuttings methods to reproduce.Depending on the thickness of the cuttings material, it is divided into two types: fine branches and columnar cuttings.
1. Fine cuttings
Combined with trimming.When the Brazilian wood grows to a certain height, the plant shape becomes empty because the lower leaves fall off. At this time, the too high part should be cut off.First cut the branch into the required length, and then cut the cuttings.Cutting matrix requires cleaning to avoid cutting cuttings.Cuttings can be cut upright or buried horizontally in the matrix.If you cut the cuttings upright, pay attention to the upper and lower end of the stem. If you insert the upper end, it will affect the rooting and survival of the branches.If the Brazilian wood cuttings are dipped in the acetic acid solution with a growth hormone 1000mg/L, or the 100 mg/L ATP root powder is treated, it can be rooted early.New roots can be germinated in the temperature and humid environment of 25-30 C for about 30 days.
2. columnar cuttings
Cuttings are used to cut 6-10cm or even 10cm or even 10cm.The tree section of cuttings should be fresh, and its Skin is light yellow.The matrix of the cuttings uses a coarse dried river sand, the depth of the sand bed is about 30cm, and the substrate is disinfected with the liquid liquid such as Bacteria before cutting.When cutting, it should be carried out according to the tree segment of different heights. The depth of the cuttings is 10-25cm, and the tree segment will not be dumped.The tree section above 1m is easy to dump. When cutting, the tree section is tied into a line rope with a thin bamboo pole and fixed.If the tree segment is dumped, it should be fixed in time.The spacing of the cuttings tree is about 10cm.Cuttings should be carried out in a protective area to maintain higher temperature and humidity.When light is strong, 45%to 75%of light should be covered.After cutting, water the water to keep the matrix moist.Regardless of the length of the tree, it can germinate on the upper end.After cutting through 30 to 35 days, the buds can be seen.When the buds grow to 5 to 10cm, potted plants can be placed.
In addition to the interception update of the bald plant at the base, the method of high branches (high pressure, air pressure bar) can also be used.Brazilian wood can also be used for sowing and breeding, but it is often difficult to get mature seeds.
Prevention and treatment of pests and insect pests
Stem rot prevention:Strict quarantine and discovering the timely destruction of the diseased plants.It is advocated to be maintained in sunlight greenhouses and strengthen ventilation at high temperature and high humidity.At the beginning of the onset, 3000 times liquid with 10%high -water dispersed particles or 600 times liquid solution of 27%copper noble suspension, 50%methyl sulfuric sulfur sulfur suspension 800 liquid, 50%sterilized king (chlorofrocarline uric acid)The water solution powder 1000 times liquid, 75%peribilobacteria cleaner wettable powder 600 times liquid, 70%methacotobadin wettable powder 1000 times liquid spray to prevent and control it, spray once every 10 days, and spray 2 to 3 times in a row.
Prevention and treatment of epidemic disease:Promote the cultivation of rain to prevent moisture from staying.In the early stage of the onset, a 58%metharic zinc wettable powder 800 times or 75%peribilobacteria cleaner wettable powder 600 times liquid, 50%methamphetamine copper wettable powder 500 times solution, 64%antivirus alum wettable powder 700 times solution, 72%creamy manganese zinc wettable powder 600 times liquid, 60%extinguishing cocoa wettable powder 1000 times solution, and 70%Bidford wettable powder 600 times liquid spray prevention.
Prevention and treatment of gray mold disease:During cultivation, the soil is moist and sunshine, and the soil is loose, fertile, and well drained. The wintering temperature is not less than 16 C.When entering the rainy season, remove the diseased body, drain water in time after the rain to prevent moisture staying, and strengthen ventilation and light transmission.In the early stage of the onset, a 50%albiane wettable powder 1000 times or 50%mildew wettable powder 800 times liquid and 30%high water suspension 800 ~ 900 times liquid spray control.
Anthracnose prevention:Press the garden soil, rot leaf soil, fragmented wood chips or sawdust, mix with 2: 1: 1 as potted matrix.From April to August, the peak growing season of people, pursuing thin Fertilizer every 20 to 30 days, placed under the condition of bright scattered light, so that it can grow strong and improve the disease resistance.At the beginning of the onset, a 50%methyl sulfur sulfur sulfur suspension 800 times liquid or 25%charcoal special wettable powder 500 times liquid, 30%oxygen chloride suspension 600 times liquid, 10%high -water decentralized particles3000 times liquid, 70%methyl sulfurizer wettable powder 1000 times solution, 50%compound sulfuric wettable powder 100 mouth liquid, and 50%benzobenic wettable powder 1000 times liquid spray control.Family potted disease plants can apply medical Dakannin ointment on the lesions.
String beaded sickle leaf spots prevention and control:Placing Brazilian wood in the shed should not be too dense. Put it lightly when moving to prevent wounds in the collision of the branches and leaves.When onset, use a 25%phenobenzobenzobacterium zinc emulsion 800 times liquid or 75%peribilobacteria cleaner wettable powder 600 to 700 times liquid, 50%methacopus sulfur sulfur suspension, 800 times liquid spray, every 10 days every 10 daysSpray it once on the left and right, spray 2 to 3 times in a row.
Pest control
Cascia flat moth (banana moth) control:When buying Brazilian wood, you should check carefully and choose a strong plant without insects to prevent the occurrence of insect pests.For a large amount of planting, the pharmaceutical agent was sprayed by 20%chrysanthemum 300 times liquid or 20%quick -eliminating diced milk oil.Flat moth adults have no night out of the mosquito. When they are planted by the family, they can combine the smoked mosquitoes to place Brazilian wood on the mosquito repellent place to drive the adult insects that produce eggs.The damaged and dead Brazilian wooden pillar was burned in time to avoid expanding the harm.
Prevention and control of grain materials:When insect pests occur during growth, 40%oxidize the lotion of the emulsion of 40%oxidation of 90%of the enemy's renovation every 7 to 10 days.Burned the damaged plants in time.
Red Spider Control:When the red spider occurs, the 7051 pesticide (insecticide) 1300 times liquid or pyrodiam (ketone) 1000 times liquid is destroyed.
What to do if the leaves are yellow
Reasons 1: Soil and soil partial alkali
It is best to use corrupt leaf soil, cultivating soil, and rough sand soil when potted Brazilian wood.The leaves are yellow.
Solution: When cultivating, it is necessary to be suitable for the growth of Brazilian wood. During the growth period, it must be evolved into alum -poured Fertilizer water, which is conducive to its growth.
Reason two: too much watering
There are not much water required for potted Brazilian wood. As long as the surrounding air humidity is high, do not allow water to accumulate water in the pot soil to avoid the phenomenon of rotten roots.Too much watering will cause Brazilian wood to be in an excessive humid environment for a long time, which will cause hypoxia in the soil to appear, so that some of the roots will rot, so that Brazilian wood can not grow normally or absorb nutrients to absorb nutrients.It is the phenomenon that causes yellowing of Brazilian wooden leaves.
Solution: When there is a little yellowing of the leaves, it is necessary to stop watering and fertilization, and often give the Brazilian wood pine soil to make it better ventilation.
Reasons 3: Excessive watering amount
Brazilian wood is not high in water for the growth environment, but the requirements for humidity are relatively high. If the amount of water is too small and the air is relatively dry, it will cause the leaves to be dull and lustrous.The status quo of yellow fall off.
Solution: At this time, a small amount of watering and spraying of water on the leaves or around the leaves, or the plastic film cover is used to put it on the Brazilian wood to increase its humidity, and then wait until the Brazilian wood is restored to normal, and then then, then thenSlowly return to normal watering.
Reason 4: Insufficient light
Brazilian wood likes to grow in a sunny place. If it grows in the shaded place or where the light is insufficient for a long time, it will cause yellow branches and leaves.
Solution: In this case, Brazilian wood is placed in sufficient light, but it is not a very strong environment.
Reason 5: No ventilation
If Brazilian wood grows too much nitrogen when applying nitrogen, branches and leaves will grow very lush. If it is trimmed from time to time, it will cause insufficient light in the inner bore branches, which will cause the leaves to yellow and fall off.
Solution: It is best to reduce fertilization in such a situation, and then perform some trims on a regular basis. Putting Brazilian wood in the air transmittance is the best.
Reason 6: Insufficient fertilization
If Brazilian wood does not fertilize on time during the growth period, or has not been treated with ammonia and potting soil for a long time, it will lead to the lack of nitrogen in the soil, making the branches and leaves grow lush enough, and the leaves will become yellow.
Solution: In this case, it is best to change the soil, apply a loose and fertile culture soil to change the basin, and slowly apply some thin rotten liquid fat and composite flower Fertilizer.
1. Brazilian wood grows strong and can form large plants.However, the plants are too tall, or the fall of the lower leaves affects the ornamental effect and needs to be trimmed.When trimming, if you cut it from the top of the plant or about 15 cm from the ground, you will sprout under the cut mouth and grow new branches.
2. The wintering temperature of Brazilian wood should be kept above 10 C. The cold resistance capacity of the silver line Brazilian wood is slightly stronger, and the temperature cannot be lower than 8 C.Fertilization should be stopped after late August to enhance the wintering ability.
3. Brazil Mu Xi High and Wet (70 % 80 %) environment.When the new leaves are pulled out, if the air is too dry, the leaf margin and the leaf tip are prone to dry rolls, and the water spraying the leaf surface and the surrounding environment should be strengthened during the growth period.During the growth period, the city pays attention to full water supply and keeps the pot soil moist, but avoids water.
4. When the plant grows too high and the lower part is empty, the long part can be intercepted.After the interception, new branches will be germinated under the cut -off part of the part to form a more ideal plant type.
