The latest 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.
