During the hot summer, the temperature is high and the air is dry. However, in order to reduce the temperature on the surface of the tissue, the transpiration must be strengthened to increase the contradiction between the supply and demand of water. At this time, the imbalance of the moisture of the fruit trees will easily occur, causing the leaves to wither and cause sunburn. Illness, severe defoliation, fruit drop, and even death. Therefore, the fruit trees should also prevent heat stroke during summer days. The specific methods are: First, to strengthen the tree potential: To prevent fruit trees, "heat stroke", the fundamental one is to strengthen fruit tree soil fertilizer management, enhance the tree's resistance to stress, such as the root system developed, strong growth Fruit trees are not prone to "heat stroke" in fruit trees. Second, loose soil cover. That is, cultivating loose soil between rows of fruit trees and cutting off the soil capillary to prevent water evaporation. At the same time, it can be covered with straw, grass, leaves, etc., to promote the grass orchard method to increase the water absorption and water retention capacity of the orchard soil so as to meet the fruit tree water requirement. Third, reasonable irrigation: In places where conditions can be regularly irrigation. Irrigation water irrigation in the morning or evening, so that the water slowly into the soil as well. This will not only satisfy the absorption of water by fruit trees, but also reduce the temperature of orchards and improve the microclimate of orchards. Fourth, spray water humidification. During the hot summer season, watering and humidifying the tree of the fruit tree in the orchard every day can effectively prevent sunburn, falling leaves, fruit drop, and cracking fruit from “heat strokeâ€.
