Devil Vine, Golden Ge, Gold Vine, Mulberry Leaf

Morphology

The stems of the large leaf green dill are stout, which can reach a few meters, and the stems have gas roots.Young leaves have ovate and heart -shaped. The newly breeded seedlings are smaller and the color is lighter. With the growth of the plant age, the mature blades are long ovate, about 15 cm long, and about 10 cm wide.The thick green leaf surface is inlaid with irregular spots or strips of yellow and white.Due to the differences in Fertilizer and water conditions, the size of its leaves is different.Large leafThe green streams are leafy, have good shade -resistant, are green all year round, and they are shiny.In winter, Outdoor plants withered and withered, and indoorsLarge leafThe green dill is lush, so it is Ye Jiahui indoors.becauseLarge leafGreen Luo's stems grow faster. People often make pillar -style cultivation, that is, pillars are erected in the center of the Flower pot, and some brown hairs are bandaged on the pillars. The diameter of the pillar is 10 cm to 12 cm.The seedlings make their stems grow around the pillars.AlsoLarge leafGreen Luo is planted in a Flower pot and placed on the Flower stand, so that the stems are Hanging down, like a green curtain, which is unique.

Potted plantLarge leafDue to the restrictions of potting soil, the green dill is easily aging after the cultivation time is too long, and the leaves become smaller and fall off.Therefore, after 2 to 3 years, the pots must be replaced or trimmed and updated.

variety

Blue leaf green dill: All leaves are blue green, without patterns and mixed colors;

Yellow leaf green (golden gold): The leaves are light golden yellow, and the leaves are thin;

Flower leaf green dill: Flower leaf green dill refers to the color of different colors on the green spots. According to the color and characteristics of the pattern, there are three variants that have been found;

Yin Ge: The leaves are milky white spots, which is thicker than the original variant;

Three -colored Ge: leaves green, yellow milk and white spotted patterns;

Star dot vine: chloroplastment green, full of silver green plaques or spots.

Suitable place

Big leaf green is strong, with well -developed air, colorful leaf, evergreen, long -seasons, and long branches. It is an excellent leaf -viewing plant.In the halls and hotels, it can also be cultivated into the study, window sills, walls, walls, and walls. It can also be used for plants in the tree -lined land. It is a flower that is more suitable for indoor places.

Effectiveness and role

Adsorption

1. Insuctions adsorption

Big leaves green can absorb benzene, vinyl chloride, formaldehyde, etc. in the air. According to environmentalist scientists, most of the new newly renovated new ventilation, and then placed a few pots of large leaf green dills.The new floor floor is very prone to harmful substances.Because the large leaf green dill can purify the benzene, trichlorohylne and formaldehyde in the air at the same time, it is very suitable for the newly repaired rooms.

2. Nano adsorption

The pore pores are arranged between 0.27-0.98 nanometer.At the same time, the diameter of the molecular diameter of formaldehyde, ammonia, benzene, gyrene, and dysrene is between 0.4-0.62 nanometers, and they are all polar molecules. They have the characteristics of harmful gases such as formaldehyde, benzene, and tvoc to achieve purificationThe effect of indoor air.

3. coconut carbon adsorption

coconut carbon is a new type of activated carbon based on coconut shells as raw materials, which is made of high temperature activation and carbonization.It has 5 times higher than ordinary activated carbon to more than above the ordinary activated carbon. The adsorption rate is faster and faster. coconut carbon -wide has a developed ratio of the surface area and a rich micro -pore diameter.The surface area can reach 1000-1600m2/g, the volume of micropores is about 90%, and its microre pore diameter is 10A-40A.It has the advantages of larger surface area, moderate pores, uniform distribution, fast adsorption speed, and small impurities.It has a strong adsorption effect on harmful gases such as formaldehyde, benzene, and tvoc.

Air purification

Big leaves have a strong air purification function, and have the reputation of green purifiers.Big chloroplasm can convert formaldehyde into sugar or amino acids such as sugar or amino acids in metabolism. It can also decompose benzene emitted by a copy and printer, and can also be absorbed.

Big leaves green stems are soft and soft, and the leaves are beautiful and pleasing to the eye.In addition to high ornamental value, environmentalists have found that a pot of large chloroplasma in 8-10 Square meters is equivalent to a air purifier, which can effectively absorb harmful gases such as formaldehyde, benzene, and vinyl chloride in the air.

Viewing value

Big leaf green dill has strong entanglement, well -developed air, colorful leaf, evergreen in the four seasons, and long branches. It is an excellent leaf -viewing plant.In the halls and hotels, it can also be cultivated into the study, window sills, walls, walls, and walls. It can also be used for plants in the tree -lined land. It is a flower that is more suitable for indoor places.

Breeding method

illumination

The original growth conditions of the large leaf green dill are in the woods covered by towering trees, and the positive is not strong.However, in the north of autumn and winter, in order to supplement the lack of temperature and photosynthesis, it should increase its lightness.

Method: Put the large leaf green dill to the best place for indoor light, or move to the sealed balcony at noon to bask in the sun.At the same time, when the temperature is low, you should open the window as little as possible, because the leaves may be frostbite within a very short time.

The indoor cultivation can be placed next to the window, but to avoid direct sunlight.If the sun is too strong, it will burn the leaves of the large leaf green dill. After the overcast, the beautiful marks on the leaves will disappear. Usually, it will receive four -hour scattered light.Therefore, the large leaf green dill can be placed in four seasons in the room.In a darkest room, it should be moved to an environment with strong light every half month to restore for a period of time.

Big leaves green, summer, and autumn can be placed near the east or north window sill, and winter can be placed in the south window.If it is placed in an environment where the light is too dark in the long run, it will not only cause the vines, the length of the interval, the scattered in the plant shape, but also the yellow and white strip spots on the leaves will become smaller and light, and even the spots completely disappear.Faded into green.If it is cultivated outdoors, pay attention to Shading, especially in summer to prevent direct light from direct light.

Humidity/watering

The amount of watering in autumn and winter shall be strictly controlled according to room temperature.Before heating, the temperature was low, and the soil of the plant was slower. To reduce watering, the amount of water should be controlled between 1/4-1/2.Even after heating, watering must not be diligent. Watering should be poured less to the pot, and brown silk should be seeprated.In addition, water should be sprayed with the roots of the brown pillars to reduce the insufficient water absorption of the roots due to the rapid evaporation.The water that is poured in winter is better after drying for a day.

temperature

In the north, room temperature is above 10 C, large leaf green dill can be safe to pass winter, room temperature is above 20 C, and large leaf green dill can grow normally.Generally, this temperature problem is not large. It should be noted that the temperature difference is too large. At the same time, it is necessary to pay attention to the leaves not to be close to the heating equipment.

soil

In winter, it can grow well under the bright scattered light in the room.The root of the stem is absorbed.It can apply nitrogen, phosphorus, potassium Compound fertilizer every 2 weeks or spray 0.2%per week of dihydrogen phosphate solution to make the leaves green and green, and the spots are more vivid.The large leaf green dill likes moisturizing. Watering in the growing season is advisable to keep the pot soil moisturizing. Do not dry the pot soil.If too much watering causes pots of water, it is easy to cause rotten roots and dead leaves, especially when the temperature of the winter room is low, and pay attention to controlling watering.While fully watering in summer, pay attention to spraying water on the leaves.Dry climate in winter, it is necessary to spray the blades with warm water every 4-5 days to wash off the dust on the leaves to help keep the leaves bright and green.

Fertilize

In the autumn and winter seasons in the north, plants grow slowly or even stop growth, so fertilization should be reduced.Before the winter, the time was mainly about 15 days.After winter, fertilization is mainly sprayed with leaf surface, mainly spraying through the pores on the leaf surface, absorbing Fertilizer through the pores on the leaf surface, Fertilizer effect can directly act on the leaf surface.Leaf surface Fertilizer should be used with special Fertilizers, and ordinary inorganic Fertilizers are not easily absorbed by the leaf surface.Both the Peking University's Hua Hua Shen series and the flowers produced by Japan can be used as leaf Fertilizer.

Plastic surgery

Each pot is planted or cut directly or cuts 4-5 plants, and a brown column is set up in the middle of the pot, which is convenient for large-leaf green dill to grow upward.Plastic trimming is carried out in spring.When the stems are covered with brown columns and the tip end exceeds about 20cm of brown columns, the stem tip of 2-3 plants is cut 40cm.When the short -term emanating new buds and new leaves, cut off the stem tip of the remaining plants.Pot plants that are frozen or other reasons in winter or other reasons, the half of the plants can be shortened by 1/2, and the other half of the stems can be cut off 2/3 or 3/4.Staged high and low, so that the new leaves with rice under the cut mouth can be covered with brown columns.

Cultivation points

Big leaves grow rapidly, and the cultivation management is extensive.In the process of cultivation and management, spray water in the summer should be sprayed with plants in many ways, and fertilization is performed every 10 days to keep the leaves green.Potted seedlings should be cut off when the cultivation column grows at 30cm; when the leaf leaves fall off 30%-50%, it should be discarded.Green -pillar potted plants are the ideal plants of the garden door and green wall greening. Its leaves are also a good product for flower arrangement and leaves.

1. Big chloroplasses are the best for cultivation of micro -acidic and neutral sandy loam with organic matter and organic matter.When changing the pot every three years, the large leaf green dill is a negative plant. It avoids direct sunlight, likes to scattered light, and is more yin to withstand. It is usually the best for receiving four -hour scattered light.

2. The breeding uses cuttings and buried stems.Choose a strong large leaf green vine, cut it into two sections, not to hurt the gas root, and then insert into the plain sand or cedar. The depth is 1/3 of the cuttings.Moisturizing, the improvement rate is more than 90%.

3. The air humidity and humid environment with large leaf green dill.summer is the peak of the growth of large leaf green dills. It can spray several times to the roots and leaf surfaces of the large leaf green dill several times a day.The temperature of the leaf surface increases the air humidity of the small environment, so that the leaves grow better.Sprinkle new high -fat film to keep Fertilizer and keep it. In winter, it has a low room temperature. The large leaf green dill is in a dormant.

4. The most suitable growth temperature of large leaf green dill is 20 C-28 C during the day, and 15 C-18 C in the evening.As long as the indoor temperature is not less than 10 C in winter, the large leaf green dill can safely overwinter. If the temperature is lower than 5, it can easily cause fallen leaves and affect growth.The timely spraying of strong stem spirit during the growth period can make the plants thick, thick leaves, tender leaves, and lush plants.

Frequently problem handling

Breeding method

Cuttings

Usually the breeding of large leaf green dill adopts cutting method.In the late spring and early summer, the strong large leaf green vines are selected, cut 15 cm to 30 cm branches, remove the leaves from 1 to 2 sections of the base, be careful not to hurt the gas roots, and then insert it into the sand or corn.One -third of the cuttings are placed in the shade of the shadow, and every day, spray water or cover the plastic film to moisturize every day. As long as the environment is not lower than 20 C, the survival rate is more than 90%.

The specific method of cutting method is as follows:

1. Cutta selection and processing

Cuttings should choose half-wood branches that grow strong and disease-free insect pests, cut them into 10-13 cm long, cut the lower incision to cut into oblique mouth, leave 2-3 leaves at the upper end, and cut the leaves by half to reduce the evaporation of water, which is conducive to cuttings.

2. Cutting matrix

Cutting matrix requires loose and breathable, well drainage, and patorial soil or sandy soil with high humus. It is best to use vermiculite. This is fast -rooted and high survival rate.Before insertion, use 2%formalnium or 5%potassium permanganate to disinfect soil.

3. Cutting method

Dip the prepared cuttings at the lower end of the cuttings or dharine, and then insert it into the matrix prepared in advance, enter the soil for 1/2, pour water, make the cuttings close with the matrix, and then cover the plastic film.

4. Manage after insertion

(1) Pay attention to keep the soil moist and high air temperature.The soil humidity should be about 50%, while the air humidity is 80%-90%.

(2) In the early stage of cuttings, the yin -covering degree of shade is maintained at about 80%, which can prevent strong light from direct sunlight and ensure sufficient scattering light, so as to use leaf scratches for photosynthesis, which is conducive to rooting.

(3) Through the above treatment, it usually takes root after 20 days, which can be removed to remove the film and increase light. At the same time, you must pay attention to the leaf spray and shade in summer and sunny. Pay attention to cold in winter.

Water insertion

Big leaf green dill can also be inserted with top bud water. The method is to cut the tender stems 20 cm to 30 cm long into a section, and directly insert it in the bottle of the water. Change the water once every 2 days to 3 days.God can take root.Due to the restrictions of the pot soil, the potted large leaf green dill is easily aging after the cultivation time is too long, and the leaves become smaller and fall off.Therefore, after 2 to 3 years, the pots must be replaced or trimmed and updated.

Prevention and treatment of pests and insect pests

anthrax

The germs are more harmful to the middle of the leaves and can also harm flowers.At the beginning,The diseased department appears wet reddish -brown or dark brown pyston -shaped spots. There is a fade green halo around the spots. After expansion, it is elliptical or long strip plaques.The strap -shaped spotted pattern converged.Because of its black brown, it is also called dark spots or dark brown disease.The infection can be repeatedly invaded during the growth period.

Control method:

1. There are many pesticides that can prevent anthracnose, such as Daisen -zinc, multi -bacterial spirit, Tapo, anthrae, etc., all have certain prevention and treatment effects.

2. The 1500 times liquid of "Sub -Gong" made by Germany is a special effect of treating anthracnose.

Root rot

Control method:

Spray 50%of the polymorphic wettable powder 500 times liquid or 5%fungan pellets, and can be irrigated.

Chloropathy

Control method:

Clear the disease leaves, pay attention to ventilation.95%of the 500 times liquid of Dakayon ammonium, or 80%of the polymorrhea wettable powder 1000 times liquid and other spray control.

What to do with yellow leaves

1. The large leaf green dill bought in winter is generally frozen, so the phenomenon of yellow leaves will soon appear in the room. After these frozen yellow leaves are completed, new leaves will be re -issued in the spring Festival.

2. Generally, the newly bought large leaf green dill has a adaptation period of about 1 month. The yellow leaves at the bottom are normal, but remember that the yellow leaves or dead leaves should not be peeled directly, and cut from the middle of the petiole.Dipping causes too much water loss and increase the wound, which will cause the upper blades to yellow.

3. Although the large leaf green dill is not afraid of the darkness, the very dark environment can also cause yellow leaves. It can be moved to a place with a good light on a regular basis. At the same timeIt will cause the whole plant to die.

4. Pot soil is too dry or damp. Both situations will cause metabolic abnormalities, damage to the root system, and cause yellow leaves.

5, lack of Fertilizer, yellow leaves will also appear in malnutrition. At this time, Fertilizer should be supplemented in time.You can fertilize with beer appropriately.

Method: Press 1: 1 ratio beer to mix water and spray stems and leaves.

6. Too much topdressing can also cause roots, resulting in yellow and withering leaves. You can dilute Fertilizer with water to allow nutrients to flow away with the water.

precautions

1. It is also necessary to ventilate the green dill.

2. Watering can be wet on the pillars.Spray the leaves to spray nitrogen fertilizer on a regular basis, and pour a sulfate diluted solution in the soil.

3. If the leaves are already yellow!Be sure to pay attention to controlling too much water or too little!At this time, you should put the green dill in a place with a well -ventilated place!

4. Green Luo is afraid of freezing, and it will be dark until death.

5. When the green dill is long, it should be cut off or climb the head to climb down the head. Do not let it grow randomly.

6. Green Luo toxin: The green dill is evergreen in the four seasons and can absorb toxic gases, but the liquid juice of the green dill is toxic. When it comes to the Skin, it will cause red itching. Mistakes can cause sore throat.

Antlers Begonia, nicknamed smoked chrysanthemum, Fanxing family, antlers and begonia are perennial flesh -quality shrubs, leaf pink green, high fleshy, bases are combined with three edges, and the whole plant is tightly drooping.flowering.

Native to southwestern Africa, China has introduced cultivation.Pleasant warm and dry environment.Drought resistance, afraid of high temperature and humidity.Require loose sandy soil land.The best temperature for winter maintenance should not be lower than 15 C.It is easy to reproduce, generally cuttings.Its leaf -shaped leaf color is more beautiful, colorful, and high ornamental value.

Morphology

Multi-pulp meat shrubs, 25-35 cm height, old branches gray-brown, woody, tender and greenIn color, the branch has a section.

Leaves and each other are alive, and 2 leaves are located in the base.The leaves are half -moon -shaped, triangular, pink green to gray -green; the leaf end is narrow, the apex is sharp, the leaf tip is slightly pink, the leaf back has keel -like protrusions, and the side buds to the leaf axis extend.The leaf length is 2.5-3.5 cm, and the width is 0.3-0.4 cm.

The flowers are large, the top, with short stalks, single or several times, the stems of the flower are 3.5-4.5 cm.The petals are white and the stamens are yellow.The meat quality, the majority of the seeds.winter flowering.

Growth environment

Antlers Begonia is warm and dry and the sun is sufficient, not cold -resistant, drought -resistant, and afraid of high temperatures. Pay attention to Shading in summer, otherwise it is easy to wrinkle on the surface.The temperature in winter is best not less than 15 C.It is suitable to grow in sandy loam soil with good drainage, loose, and breathable.

Distribution

Located in southwestern South Africa, the population is distributed from southern Namibia to the northeast of Ritter Feld.China has been introduced and cultivated in various places.

Breeding method

Cuttings: The best in spring and autumn.Choose a chargeReal and mature stem nodes, cut into small segments of 8-10 cm.In the micro-tide sand bed, the room temperature is kept at 21-25 C.After cutting, 15-20 is rooted, and the front leaves of the hair will have severe wrinkles, which is normal.After 3 cm in length, potted pots can be moved.The growth rate of the group is accelerated.

Sowing: In the spring of April to May, the indoor basin was used to broadcast, and the temperature of the germination room was 20-24 C.The roots of the seedlings are fine and shallow. Watering needs to be cautious. It is best to spray the watering pot.Keep moist and cool, move seedlings after one month.

Cultivation technology

Soil: It is better to breed the soil for the soil of the antlers.

Environment: Antlers Begonia should be kept in a sunny environment.

Watering: Antlers Begonia does not need to keep the soil humid for a long time, and keep the soil dry. Therefore, watering should be moderate. This kind of drought is resistant to drought and dies, but it is easy to rot because of accumulating water.

Pests and insects: When the potting of the antlers Begonia is too much humid, the root causes are often occurred, and the 3% Dan particles can be used for prevention and treatment.Pests are harmful to garaphs, and 55%killing pine emulsion oil 1500 times liquid to kill.

illumination:If the antlers and begonia burst, it must be shade in summer, because its growth does not require a strong light, and the appropriate Shading treatment can avoid slow plant growth. At the same time, it can grow in a breathable position to grow.Quick and lush.

temperature:Antlers Begonia's temperature requirements are relatively high. Generally, in an environment of about 20 degrees, it can grow healthily and thrive. If the temperature is too high in summer, the antlers and begonia will stop growing.In winter, when the temperature is lower than 15 degrees, it will also affect its growth. This will affect the chance of the plant explosion and the phenomenon of frostbite the plants.

Four seasons maintenance

spring: Change the pots in spring every spring, and trim the whole plant. Add fertile peat soil or corrupt leaf soil andThe mixed soil composed of coarse sand can be sprayed a little.In the spring growth period, it is based on keeping the pot soil.

summer: Antlers Begonia is half -dormant in summer, which can be kept in semi -yin and keeping the pot soil is not too dry.However, if direct radiation is adopted, the direct -to -leaves will occur or even burns. Because the steaming effect is too strong, the blade cracks or produces wrinkles.It is recommended to place scattered semi -yin in summer.The sunshine time is reduced to 2 hours a day, while the number of watering times is reduced.

autumn: Antlers Begonia started to grow after autumn, fertilizing once every half a month.

winter: Antlers Begonia grows in winter and leaves.When the room temperature is kept at 15-20 C in winter, flowering continues.After 2-3 years, the potted plants need to be re-updated.

Main value

Antlers and begonia plants are often clustered, and they are often used in potted plants or Hanging in Europe and the United States.Potted plants.The green and thick leaves extend outward, with a good sense of Hanging.planting with other varieties of succulents can also play a very good embellishment.When the flowering season blooms, the golden and bright flowers add a lot of color to the potted plants, Hanging it indoors, which is more vibrant and highlights the festive atmosphere.Because of its simple maintenance, easy reproduction, and strong habits, it is also used to lay out succulent plant theme parks. It is an excellent ornamental flower variety.

What should I do if my horn begins is wrinkled

Antlers Begonia is a kind of succulent plant that likes water. Wiring of antlers and begonias is likely to be a reasons for the lack of water.When the antlers are wrinkled, you need to water the antlers and begins in time, and you need to pour it through, and then put the antlers and begins in a well -ventilated place.It is necessary to water it when the pot of the antlers and begins should be watered when it is dry. When watering, try to avoid pouring on the antlers' bells of the antlers.

In the summer, the antlers and begonia will enter the semi -dormant period. Watering should be controlled. The suitable watering time is in the evening.By the time of the growth period of the antlers and begonias, the frowning of the antlers and begonia has not improved, and it is necessary to consider whether the root of the antlers and begonia must have a problem, and the antlers can be dug out of the soil.

What should I do if the antlers Begonia

Antlers Begonia is long, usually lack of light, light light, and more watering.The antlers Begonia has no way to change it back, but you can wait until the growth period of the antlers and begonia -spring and autumn. After cutting the top of the antlers and begonia, dry the wound and cutting.Note that in the future breeding, in the three seasons of spring, autumn, and winter, there must be sufficient light for the antlers and begonia. If the light is limited, you can properly control the watering.

precautions for Antlee Begonia

1. If the antlers Begonia is potted, it requires that its pot soil needs drainage and ventilation.The soil humus cannot be too much, and the general soil is fine.The size of the pot is determined by the length of the roots.

2. Antlers Begonia do not like moist or dry. Generally, it is recommended to water the cement soil without drying or watering. To maintain a certain humidity in summer, you can pour more water on the leaves.

3. The growth of antlers Begonia is generally recommended to use the light. In summer, because the temperature is too high, it is recommended to place them in a shade to keep the soil.spring and autumn grow strong, so you can make appropriate light,

4. In the growing period, the antlers Begonia is generally recommended to fertilize in spring and autumn. The Fertilizer is thin Fertilizer.

5. The temperature for the growth of antlers Begonia is recommended to be around 20 degrees Celsius. If it is lower than 15 degrees Celsius and it will not grow, but it will stop growing or even wrinkles.And try to place it in a cool place in summer.

[seed preservation temperature] How long can the seed cold storage storage be reached?

Validity of vegetable seed preservation

Vegetable seed germination rate is very related to the preservation period, different vegetable species, and their preservation years are different.

tomato:Generally, it can be stored for 3-4 years, and the longest does not exceed 4 years. Otherwise, the method of reducing the bud rate will be reduced. The method of identifying the old and new seeds is that there are furry on the new seeds and tomato flavors.

Cucumber:At most 2-3 years, which exceeds this period, the period of the deadline is generally reduced by 20-30%. Even if it can emerge, some often have no true leaves after seedlings, and it is not easy to survive.

eggplant:seeds that are generally within 6 years can be used. The new seeds are shiny, and the old seeds reduce the luster according to the storage period.

chili:It must not exceed 3 years, otherwise the bud rate will be reduced, the bud rate of 2 years will be reduced by about 10%, and the storage of three years will be reduced by about 30%. The new seeds are golden yellow, and the Chen seeds are apricot yellow.

Scallion seed:In the summer, the green onions must be used to use the new seeds of the year. If the seeds of the aged, the green onions will smoke moss.The spring onion can be produced in the first year.

coriander:It must be stored for one year, but the storage time should not exceed 3 years.Otherwise, the fragrance will become smaller.

celery:It can be stored for 3 years. The seeds that year cannot be used in that year, and it must be used for one year.

Chinese chives:The new seeds were good at that time, and the germination rate of two years was greatly reduced.

Chinese cabbage:It can be stored for two years. The seeds harvested in that year can be sowed in that year, but if more than two years, the seedling rate is reduced by 20-30%, and the disease resistance is low.
