Culture methods and matters needing attention of Douban Green

Douban Green is a perennial evergreen herb of Piperaceae. Small potted plants are often cultivated in white plastic pots and white porcelain pots, which are placed on tea tables, decorative cabinets, ancient shelves and desks. it is very beautiful, or any branch spreads and hangs in front of the indoor window or bathroom. it is also very fresh and pleasing to the eye. Let's take a look at the breeding methods and matters needing attention of Douban green.

The growth habit of Douban Green

Douban green grows on wet stones or dead trees and is distributed in America, Oceania, Africa and tropical and subtropical Asia. Like warm and humid semi-shady environment, the suitable temperature for growth is about 25 ℃, the lowest is not less than 10 ℃, not resistant to high temperature, requires high air humidity, avoid direct sunlight, like loose, fertile and well-drained moist soil.

Propagation method of Douban Green

1. Cuttings: from April to May, select strong top branches, about 5 cm long as cuttings, and keep 1 or 2 leaves in the upper part. After the cut is dried, it is inserted into the wet sand bed. You can also insert leaves, cut the leaves with petioles with a knife, dry them slightly, then insert them obliquely on the sand bed, and take root in 10-15 days. In a greenhouse with temperature control equipment, it can be carried out all year round.

2. Ramet: the basin soil can be made of rotten leaf soil, peat soil and some perlite or sand, and an appropriate amount of base fertilizer can be added. During the growing period, topdressing should be applied once a month, watering should be done with 1-2 days of water in the pool, and watering should be controlled in winter. The change of temperature directly affects the color of leaves. The optimum temperature of colored leaves in winter is 18 ~ 20 ℃, and that of green leaves is about 15 ℃. If you are afraid of heat in hot summer, you can spray water under the shade to cool down, but it should be noted that overheating and humidity will cause stems and leaves to blacken and rot.

The Culture method of Douban Green

1. Soil: Douban green likes to grow in loose, fertile, well-drained and humus-rich sandy soil, but not suitable for growing in clay, so the substrate is usually mixed with rotten leaf soil, river sand and a small amount of mature organic fertilizer. a better substrate can be cultivated with optional peat soil and perlite.

2. Watering: Douban Green likes water and is not resistant to drought. It should be watered frequently during the growing period, and more water should be watered when the temperature is higher than 25 ℃ or Kongqi is dry, but it should also be prevented from waterlogging. When the temperature is below 25 ℃, it should be watered thoroughly when the surface of the basin soil is dry. When the temperature is lower than 10 ℃, it can be dried for several days without watering.

3. Humidity: Douban Green likes the humid growth environment, grows luxuriantly in the humid environment, and has bright leaves. When the temperature is high or Kongqi is dry, it is necessary to strengthen foliar spraying or sprinkle water in the growing environment to maintain high humidity of Kongqi, which is extremely beneficial to the growth of plants. It can also adapt to a short dry environment, but not for a long time, generally should be kept at about 70%.

4. Temperature: Douban green prefers warm environment, the suitable temperature for growth is between 20 and 30 ℃, the overwintering temperature is better kept above 10 ℃, the growth stops below 10 ℃, and it is easy to freeze under 5 ℃.

5. Sunshine: Douban green prefers semi-overcast or scattered light, except for sufficient light in winter, shading is needed in other seasons, especially in summer. If placed in a shady environment, it is easy to grow, grow between branches, and reduce ornamental, which is not advisable. Under the semi-overcast condition, the leaf color is brighter and the gloss is better, especially the variegated leaf variety, the demand for sunlight is a little higher.

6. Fertilization: a small amount of fertilizer is needed when the temperature is higher than 18 ℃, and less or not when the temperature is lower than 18 ℃ or higher than 30 ℃. Fertilization had better be carried out several times in a small amount, and it is best to use diluted fertilizer solution instead of clear water irrigation. It is not tolerant to raw fertilizer and thick fertilizer, which can easily cause fertilizer damage. Foliar spraying fertilizer solution can also be used for fertilization, and the effect is good. Fertilizers are mainly nitrogen fertilizer and potassium fertilizer, followed by phosphate fertilizer.

7. Insect pests: Douban green has fewer diseases and insect pests, and the general diseases are caused by improper nursing and environmental discomfort, which can be gradually recovered under adjustment. The pests are mainly harmed by red spiders, but they can be prevented when keeping high humidity. When they occur, they can be prevented by wiping leaves with wet cloth or spraying special pesticides.

8, pruning: Douban green newborn seedlings, in the seedling height of about 10 cm to pick the heart to increase the number of branches, such plant type is fuller, appreciation value is also higher. The pruning of large plants is generally determined according to their growth.

What if the green leaves of Douban turn yellow?

1, light discomfort: mung bean is a shade-loving plant, as long as it provides scattered light that can carry out photosynthesis, avoid direct sunlight. Giving Douban green too much exposure to the sun is one of the reasons why Douban green leaves turn yellow. You can properly apply some fertilizer, pour some water, and put it in a semi-overcast place for a few days, and Douban green will be green again.

2. Improper maintenance: it may be due to too much water, or low temperature, insufficient fertilizer and so on. If Douban green is put indoors, astigmatism is fine, do not always bask in the sun, water thoroughly at a time, once a week. Properly replenish fertilizers and increase nutrition. If the air is dry, you can spray more water to the leaves and avoid frost.

Hydroponic culture method of Douban green

The main results are as follows: 1. Douban green water culture should be carried out in April and May, take the soil plants with better shape, wash out the soil of roots carefully, and remove withered roots and withered leaves. Soak in 0.5% potassium permanganate solution for 10 minutes, after cleaning, plant in the container, fix the root system with the medium, and inject clear water, so as to be able to immerse the water of 1, 2, 2, and 3 root systems. It is worth mentioning that the green stem and leaves of Douban are tender and tender, and it is best not to touch the water.

2. Change the fresh water in the first 2-3 days of Douban green water culture, and new roots can grow after a week. When the new roots grow to more than 5 cm, move the container and the plant to a place with sufficient scattered light for maintenance, and then use foliage plant nutrient solution to cultivate. After that, the nutrient solution will be changed every half a month.

3. Douban green should change water once a day during hydroponic culture at the beginning of April and May, clean up the sticky substances produced on the roots and put on clean water for about 10 days. After the new fibrous roots grow, the water can be changed every 2-3 days. Douban green irrigation can use river water, Rain Water, tap water, special varieties (Christmas flowers, etc.) to irrigate with Rain Water, precipitated tap water, generally not well water.

4. Douban green needs less nutrients than other hydroponic plants, and basically does not need to apply fertilization. on the contrary, excessive fertilizer in water quality is easy to cause the growth of microorganisms in water, which is not conducive to plant growth. And succulent succulent plants do not have high requirements for light, once the new fibrous roots grow, the maintenance in the future is relatively simple. When the air is dry, you can spray more water to the leaves and avoid frost.

5. Douban green has fewer diseases and insect pests, and the general diseases are caused by improper nursing and environmental discomfort, which can be gradually recovered under adjustment. Pests are mainly harmed by red spiders, but can be prevented when maintaining high air humidity, and can be prevented by wiping leaves with wet cloth or spraying special insecticides when they occur.

Matters needing attention in the culture of Douban green

1. Douban green is a semi-negative plant, which should be placed in a better position of scattered light at ordinary times, and can be placed in a place with sufficient light when the temperature is low in winter. However, if it is in too shady environment for a long time, Douban green is not only easy to grow branches and stems, but also has a light leaf color, which greatly affects the ornamental value.

2. Douban green likes the warm and humid environment, grows rapidly in spring and autumn, grows slowly or stops growing in high temperature in summer and low temperature in winter. Douban green prefers water and grows luxuriantly in the environment with high humidity, so it should often spray water on its surroundings and leaves in summer high temperature and dry season to maintain high air humidity.

3. Douban green prefers water and is not resistant to drought. Usually watering should be dry and wet, and the basin soil should not be too dry. However, when watering, we should also pay attention to avoid stagnant water in the basin, waterlogging is easy to cause root rot, leading to plant diseases. It depends on the situation at low temperatures in winter, less watering when the temperature is low, and more watering on sunny days.

4. Douban Green does not have a high demand for fertilizer and water. A small amount of fertilizer is applied in winter and summer, and thin fertilizer can be irrigated in other seasons. It is best to apply thin fertilizer frequently and avoid thick fertilizer. In order to avoid stagnant water in the basin, it is best to choose tile pots or pottery pots with good air permeability when planting. Families with heating supply in winter should also often spray water on the leaves and increase the humidity appropriately while cleaning the leaves, so that the leaves of Douban green can be green and bright.

5. The properly maintained Douban green has strong branching ability and rapid growth, so we should pay attention to pruning and cut off the high and dense branches, which can not only improve the air circulation between the branches, but also keep the plant shape beautiful.
