1. Pay attention to changing the pouring to dark pouring. A method of watering the membrane under the membrane using a floor covering film. The film prevents moisture from evaporating and reduces the humidity in the shed.
2, pay attention to change the flooding irrigation for small water. Watering in the shed should not be carried out by flooding. Because flooding will greatly reduce the ground temperature and increase the humidity in the shed, it will affect the growth and development of the tree and fruit due to the excessive decrease of the ground temperature. Watering in the shed should be small water pouring, that is, the amount of water should not be too large, and the number of times should be increased according to the weather.
3, pay attention to the amount of water in each part should be appropriate. When the temperature difference between the various parts of the greenhouse is large, the amount of watering and the number of times should be different. In the south of the greenhouse (or near the heat source of the furnace flue), the soil moisture evaporation is large, and the amount of watering and the number of watering are more appropriate. The temperature on both sides and north of the greenhouse is low, the sunshine time is short, and the amount of watering and watering should be less.
4, pay attention to ventilation and drainage. After watering in the shed, attention should also be paid to ventilation and dehumidification to reduce the occurrence of diseases. For example, the whole shed should be properly sprinkled with dried straw ash to absorb moisture and sterilize better. Ventilation time and frequency should be carried out according to the growth characteristics of tree species and varieties combined with temperature regulation in the greenhouse. Generally, the relative humidity from the film to the flowering should be kept at 70%-80%; the flowering period should be 50%-60%; %~50%; fruit coloring period is about 50%.
