Douban Green is a supermodel in hydroponic culture. Each plant has 4-5 leaves. It is easy to adapt to the underwater environment, does not decay, and is easy to grow. This is a lovely breed that increases the confidence of beginners. Like warm and humid semi-shady environment, not resistant to high temperature, avoid direct sunlight; drought resistance, watering should not be too much, especially reduce watering in autumn and winter. If the air is dry, spray more water on the leaves to avoid frosting. If it is soil culture, the culture medium needs good air permeability and good water retention organic matrix, such as peat soil plus perlite or vermiculite, the ratio is about 6: 1, to avoid too much water in the culture medium, generally keep the culture medium 40-60% water content. The product is usually placed in a bright indoor or open-air tone. The better temperature is 20-26 °C, and the winter temperature is higher than 5 °C. The potted soil remained moist, and the hydration time was about 20-30ml. If the topsoil is too wet, it is easy to grow moss. Leaves often spray water to keep the air humid. It can also be solidified for a period of time and properly trimmed or transplanted in the courtyard for viewing.

1. Matrix: Douban green grows in sandy soil that is loose, fertile, well drained and rich in humus, and is not suitable for growing in clay. The water distribution of Douban green is usually mixed with humus soil, river sand and a small amount of decomposed organic fertilizer. A better matrix can be mixed with optional peat and perlite.

two。 Lighting: Douban green is semi-negative or scattered light. Except for plenty of light in winter, other seasons need a little shade. It is very suitable for growing in the office. The incandescent lamp is just right. If placed in a cool environment, it is not recommended to grow and grow between branches to reduce ornamental.

3. Temperature: Douban green and warm environment, the growth temperature is between 20 °C and 30 °C, the winter temperature is better kept above 10 °C, the growth stops below 10 °C, and the freezing temperature is lower than °C.

4. Humidity-gt;: Douban Green is a humid growing environment. It grows vigorously in high humidity and its leaves are very bright. When the temperature is high or the air is dry, it is necessary to strengthen the water spray on the leaves or sprinkle water in the growing environment to maintain high air humidity is very beneficial to plant growth. It can also adapt to a short dry environment, but it should not last long and should generally be kept at about 70%.

5. Watering: Douban green is more like water, not resistant to drought, watering in the growing season, the temperature should be higher than 25 °C or the air should be dry, but also to prevent waterlogging, the temperature below 25 °C, the surface of the sealed soil should be reperfused when dry. When the temperature is below 10 ℃, it can be dried for several days without watering.

6. Fertilization: when the temperature is higher than 18 °C, a small amount of fertilizer is needed. When the temperature is lower than 18 ℃ or higher than 30 ℃, it is better to smear less or not. Fertilization is preferably carried out in a small amount, and diluted fertilizer is used instead of clear water. Better watering, not resistant to fat and heavy fertilizer, it is easy to cause fat damage. Foliar spraying fertilizer can also be used for fertilization, and the effect is good. Fertilizers are mainly nitrogen and potassium, and phosphate fertilizer is a good kind.

7. Pruning and reproduction: in order to enrich the plant species and increase the value added in the future, it is necessary to increase the number of branches about 10 cm in height. Pruning of large plants is usually based on growth and can be reproduced by cutting and branching leaves. The reproduction temperature is between 20-25 °C, keep the substrate moist and high air humidity, and take root and give birth within 2-3 weeks. Adventitious buds. Small buds can be transplanted when they are slightly older.

8. Hydroponics: in hydroponics, some people will ask whether Douban can be hydroponically cultured. The answer is yes. Hydroponic culture can directly cut long branches or wash the substrate after watering. After cutting, the ambient temperature is about 20-25 °C, the new root can grow in about 2 weeks, and the effect of water culture is better.

9. Diseases and insect pests: there are fewer diseases and insect pests in Douban green. Common diseases are caused by improper care and environmental discomfort. It can be recovered gradually after adjustment. Insect pests are mainly damaged by red spiders, but they can be prevented when keeping high air humidity. When they occur, they can be wiped with a wet cloth or sprayed with special agents to prevent and cure them.
