The propagation method of Douban green the technique of insertion and propagation of Douban green leaves

Douban green makes people feel very small and fresh, loved by everyone, are more keen on breeding it, its breeding methods are generally divided into two kinds, each of which has certain skills, and its cultivation methods are also divided into hydroponic culture and soil culture. today, follow the editor to understand and learn its planting method.

Propagation method of Douban Green

1. Ramet propagation

The split propagation of Douban green is mainly used for the reproduction of colored leaf varieties. when Douban green grows full of pots, the Douban green is removed from the basin, and the plants are divided into N clumps with a knife and planted respectively. Or change the big pot to plant again, wait for the growth to be stable, change the small pot.

2. Cuttage propagation

The cuttage here refers to the branch cutting, which is usually carried out from April to May, and the branch and leaf of the terminal bud has the best effect. Select the robust top branch, about 10-12 cm long, retain the upper 1-2 leaves, put it in the shade for 1-2 hours, wait for the incision to dry, insert the moist soil, and the breeding leaves are usually inserted in May. Select the robust and mature leaves in the lower part of Douban green, take off the leaves with the stalk (the leaves can be broken, but not diseased leaves), and then break the petiole into 45 °and insert it into the soil. If the temperature is controlled at 25 ℃, it can take root in about a month. Douban green leaf insertion is not in the basin cover with plastic film moisturizing, it is easy to cause leaf rot.

Techniques of insertion and Propagation of Green leaves in Douban

1. Cuttage of whole leaves of Douban Green

Cutting time needless to say, it is best in the spring when the temperature warms up, sunshine, temperature, water are indispensable. Insert a pot according to the following method. Pick the green leaves of Douban and choose the green and strong ones. Even if you don't have it at home, you can borrow a few more from a friend. After picking, put the leaves in the shade for a period of time. Wait for the leaves to wilt a little, and insert them directly into the basin. Then pour enough water and put it in a cool place. Because the cutting environment is different, it will take root and sprout between February and March. After taking root, move the leaves to the sun, and soon new leaves will grow. When the new leaves grow to 2-3 cm, they can be properly planted in pots.

3. Half a green leaf of Douban

The leaves of cuttage Douban green may be hurt during maintenance, and these leaves will turn yellow eventually. Withered, the leaves will be picked at this time, re-cutting, but also regarded as waste utilization, cuttings survive you earn, do not survive and do not lose anything. Take a look at how to do this: you can cut off the upper part of the leaf and insert it into the moist soil so that it will take root faster. Or cut off the lower part of the leaf, like this: after taking root, it can be potted, and new leaves will grow from March to April, forming a new plant.

Soil Culture method of Douban Green

1. Matrix: like to use loose, drained and ventilated imported peat of 5-40mm specification, break the peat and mix well with water. (standard of adding water: after mixing well with water, hold a handful of peat tightly and water oozes from fingers) to be planted in cup. The amount of peat in each basin of 9cm basin is about 200ml, and a pack of 300L imported peat can hold about 1500 cups.

two。 Lighting: like 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.

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

4. Humidity: like humid growth environment, luxuriant growth and bright leaf color in humid environment, strengthen foliar spraying or sprinkling water in the growth environment when the temperature is high or Kongqi is dry, in order to maintain high humidity of Kongqi, which is very 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%.

5. Watering: Douban green prefer water, not resistant to drought, usually watering to see dry and wet, basin soil can 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.

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 should be carried out in a small amount and many times, and it is best to use diluted fertilizer solution instead of clear water irrigation. 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. Pruning and reproduction: properly maintained Douban green has strong branching ability and rapid growth, usually pay attention to pruning, cut off the branches that are too high and too dense, which can not only improve the air circulation between branches, but also keep the plant shape beautiful. The mature branches cut can be propagated by cuttings, and the rooting and survival rate is very high.

8. Diseases and 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.

The reason for the rotten green root of Douban

1. Too much watering

Douban green likes the humid environment, in the air humidity environment, does not need too much moisture. If you water too much at one time, it will cause root dyspnea and root rot.

2. the temperature is too high

Douban green culture should also control the temperature, the most suitable growth temperature is 20-25 ℃, but the summer temperature is too high, the sun is strong, if we do not take proper cooling measures, it will lead to black stems and leaves, resulting in rotting roots.

3. Improper fertilization

Douban green requires a lot of fertilizer and water, so we should pay attention to avoid the root system when fertilizing, so as not to burn the root with fertilizer and cause root rot.

4. Disease

Root and neck rot is one of the diseases easy to occur in Douban green, which should be treated in time and generally sprayed with 1000 times of carbendazim wettable powder.

5. Poor water quality

Douban green can be hydroponically cultivated, but pay attention to the water quality. If the water body is sticky and worried, it needs to be cleaned and replaced with clean water, otherwise it will cause Douban green root system to be contaminated and rotten.

It is not easy to cultivate beautiful flowers and plants. Although Douban green looks easy to raise, it will rot its roots a little carelessly. In normal nursing, we must pay more attention to watering too much water and applying too much fertilizer. As long as we take care of it carefully, it will certainly grow well.
