First of all, we must strengthen cold exercise. In particular, control the lower night temperature and maintain a certain temperature difference between day and night. Seedlings should be strengthened at low temperature for 7 to 10 days before planting to control the temperature and control the water and improve their adaptability to low temperatures.
Secondly, increase the light-receiving time of the seedlings and increase the light intensity, and enhance the photosynthesis of the seedlings. The inner layer coverings such as straw curtains and shade nets can be properly uncovered to keep the outer cover of the film and glass clean, and the photosynthetic nutrient film fertilizer can be sprayed, which can help the plants absorb a lot of light, light, light, and compatible conventional fertilizers. , Nutrients supply the plant growth and development to the limit. Apply once a year to benefit.
Finally, we must control the humidity of the seedbed. Humidity in the seedbed is high, the water content in the seedlings is high, the concentration of the cell fluid is reduced, and the seedlings are susceptible to freezing. It is necessary to strengthen ventilation and reduce the humidity of seedbeds. When the bed soil moisture is too high, a layer of dry fine soil or grass ash can be used to absorb moisture. The thickness is about 0.5 cm. Do not touch the leaf surface and the seedling seedling growth point when spreading fine soil or grass ash, and do it when the seedling leaves are dry.
