The Culture method of Douban Green how can Douban Green not raise rotten roots

Douban green is easy to feed, so it is one of the first choices for indoor potted flower culture. And Douban green is a better anti-radiation plant in all plants, which can effectively absorb harmful gases such as formaldehyde and carbon dioxide in the air, so it is very suitable for breeding in the bedroom.

I. the growth habits of Douban Green.

Douban green prefers a warm and humid semi-overcast environment. The suitable temperature for growth is about 25 ℃, and the lowest is not less than 10 ℃. It is not resistant to high temperature, requires high air humidity, avoid direct sunlight, and likes loose, fertile and well-drained moist soil.

Second, the 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 cut mature branches can be cut and propagated, 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.

Third, the hydroponic culture method of Douban green.

1. Substrate: Douban green soilless culture substrate can be used vermiculite: peat: slag for 1:1:1 or perlite: peat: river sand for lburel. The nutrient solution can be used with foliage plant nutrient solution or compound flower fertilizer. When putting on the basin, add a layer of gravel or coarse sand to the bottom of the basin, straighten the seedlings in the center, and then add the matrix until the basin is eight points full.

two。 Nutrient solution: the nutrient solution should be poured thoroughly for the first time until there is an exudate from the basin bottom tray. After the routine rehydration, small and medium-sized basins will be rehydrated once a week, 50ml each time.

3. Humidity: usually replenish water to keep the matrix moist, and the pH value can be maintained at about 6.5. During the growth period, clear water should be sprayed on the stems and leaves once or twice a day to keep the leaves green, especially in the dry climate and hot summer seasons.

4. Lighting: Douban green is a semi-negative plant, usually placed in a better position of scattered light, 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.

5. Temperature: pay attention to keep warm in winter, keep the room temperature above 15 ℃, and reduce the number of rehydration and watering, so as to avoid rotting roots and leaves.
