Management of greenhouse eggplant

1. The grass cover is exposed early and the light is extended as much as possible. As the outside temperature decreases, the cover time is gradually advanced accordingly.

2. After uncovering the grasshopper, first wipe the film to increase the light intensity in the greenhouse.

3. Appropriate air during the day. The size and duration of the air outlet depend on the night temperature of the solar greenhouse. The purpose of the air release is not only to adjust the temperature at the time of the wind release, but also to adjust the night temperature. The minimum night temperature is maintained between 15-18 Â°C, and the nighttime is higher than 18 Â°C. The daytime air release time can be longer. The nighttime minimum temperature is lower than 15 Â°C, and there is less or no wind during the day.

4. After cultivating the seedlings, the soil should be ploughed several times in a timely manner. It is best to cultivate three times, then apply high-quality decomposed organic fertilizer near the rhizosphere, cover the organic fertilizer and ridge in the rhizosphere soil, and then cover the mulch to promote root growth. At the same time, the stent is planted.

5. In November, no matter whether it is cloudy or sunny, it is generally not watered, controlling the growth of the aboveground parts, promoting the growth of the underground parts, promoting the differentiation of the plant seedlings, increasing the number of leaves and the number of flower organs.

6. When there is a long time, it is not necessary to slam the grass. If the wilting phenomenon occurs, you should return to the grass in time to avoid the air temperature rising too fast. The grasshoppers should be slowly uncovered, step by step, and the grasses will be uncovered after the temperature rises.

7. In the case of good management, the disease is rarely seldom, the drug should be used with caution, and it should not be used indiscriminately.

8. In the case of rain, cover the old film in the grass to prevent rain and prevent the grass from being wet.

9. Harvest fruits early, avoid falling, and help the next fruit to grow.
