Introduction to the method of hydroponic culture of Douban green

Douban green is a potted plant with great ornamental value. Douban green is small and lovely, and the plant height is generally less than 30 centimeters, which is very beautiful. It is mainly placed in the room and table, as well as the coffee table. Then how to raise Douban green? The following editor will introduce to you the culture method of Douban green water culture. I hope I can help you all.

[brief introduction of Douban Green]

Douban green originated in Venezuela, like warm and humid semi-shady environment, not resistant to cold, strong light and drought, spike-shaped, but not high ornamental, mainly ornamental leaves. Pepper grass can be divided into two types: upright clump and creeping overhanging growth. the former can be appreciated directly on the plane as a potted plant, while the latter needs to be appreciated by hanging. The cultivated varieties are variegated leaf type, flower leaf type, bright leaf type and wrinkled leaf type.

Douban Green is an excellent living model in hydroponics, with 4-5 leaves per plant. It is very easy to adapt to the water environment, does not decay, and is easy to grow. It is a lovely variety to increase the confidence of beginners. Like warm and humid semi-shady environment, not resistant to high temperature, avoid direct sunlight; resistant to drought, watering should not be too much, especially in autumn and winter to reduce watering. If the air is dry, you can spray more water to the leaves and avoid frost. If it is soil culture, the cultivation substrate requires organic substrates with good air permeability and good water retention, such as peat soil plus perlite or vermiculite, the proportion is about 6:1, avoid too much water in the cultivation substrate, and generally maintain 40-60% water content in the cultivation substrate. This product is usually placed in bright indoor or open-air shade, the optimum temperature is 20-26 ℃, and the winter temperature is above 5 ℃. The basin soil remains moist to a certain extent, and it is about 20-30ml when replenishing water. If the topsoil is too wet, it is easy to breed moss. The leaves are often sprayed with water to maintain high air humidity. It can also be properly trimmed or transplanted in the courtyard for viewing after a period of time.

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

two。 Lighting: Douban green likes semi-overcast or scattered light, except for sufficient light in winter, other seasons need a little shading, very suitable for planting in the office, incandescent lamp lighting is just right. If placed in a shady environment, it is easy to grow, the branches grow, and the ornamental is reduced, which is not advisable.

3. Temperature: Douban green prefers 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 below ℃.

4. Humidity >: Douban green likes the humid growth environment, grows luxuriantly in the humid environment, the leaf color is bright, and the foliar spray should be strengthened or sprinkled in the growing environment when the temperature is high or the air is dry, so as to maintain high air humidity. It is extremely beneficial to the growth of the plant. 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 is more like water, is not resistant to drought, should be watered frequently during the growing period, and should be watered more frequently when the temperature is higher than 25 ℃ or when the air is dry, but also to prevent waterlogging, when the temperature is lower than 25 ℃, the basin soil surface should be watered thoroughly when the temperature is less than 10 ℃, it can be dried for several days without watering.

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 diluted fertilizer solution instead of clear water irrigation is the best. It is not tolerant to raw fertilizer and thick fertilizer, and it is easy to 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. Pruning and reproduction: newly propagated seedlings, in order to make the plant type fuller in the future and improve the appreciation value, it is necessary to pick the heart to increase the number of branches in the seedling height of about 10 meters. The pruning of large plants is generally determined according to the growth trend, and the reproduction can be carried out by leaf cuttings and ramets. The propagation temperature is between 20-25 ℃, keeping the substrate moist and high air humidity, and rooting and adventitious buds can take place in 2-3 weeks. The small buds can be transplanted after they are slightly larger.

8. Hydroponic culture: when it comes to hydroponic culture, some people will ask whether Douban green can be hydroponically cultured. The answer is yes. Hydroponic culture can directly cut off longer branches or rinse the substrate in a whole basin after hydroponic culture. The ambient temperature when inserting branches is about 20-25 ℃, and new roots can grow in about 2 weeks. Hydroponic culture is more ornamental.

9. 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 can be prevented when keeping high air humidity, and can be prevented by wiping leaves with wet cloth or spraying special insecticides when they occur.
