1. As soon as the grass cover is covered, try to extend the lighting time. As the outside temperature decreases, the cover time is gradually advanced accordingly.
2. Wipe the film first after removing the grasshopper to increase the light intensity in the greenhouse.
3. Properly ventilate during the day. The size of the air outlet and the length of time depends on the nighttime temperature of the greenhouse. That is, the purpose of air release is not only to adjust the temperature at the time of air release, but also to adjust the night temperature. The minimum temperature at night is maintained at 15-18°C. At night, it is higher than 18°C. During the day, the duration of air release may be longer. The minimum temperature at night is less than 15°C. During the day, there is little or no air release.
4. After easing the seedlings, timely cultivating loose soil in many times, preferably cultivating 3 times, then applying high-quality decomposed organic fertilizer near the rhizosphere, covering the organic fertilizer while cultivating the ridge in the rhizosphere, covering the mulch, and promoting root growth. At the same time, scaffolding and plant finishing.
In May and November, no matter whether it is sunny on cloudy days, under normal circumstances, it is not watered. It controls the growth of the ground, promotes the growth of the underground, promotes the differentiation of plantlets, and increases the number of leaves and the number of floral organs.
6. Whenever there is a long cloudy day, do not expose the grasshopper. If the wilting phenomenon occurs during the exposing process, you should promptly return to the haystack to prevent the air temperature from rising too fast. Grasshoppers have to be uncovered slowly, step by step gradually revealed, and once the temperature rises, the grasshoppers will all be uncovered.
7. In the case of good management, disease rarely occurs. Use drugs with caution and avoid using drugs indiscriminately.
8. In time of rain, cover the grass in the old film to prevent rain, to prevent wet grass.
9. Earlier harvesting of fruits to avoid falling pods will also benefit the growth of the next fruit.
