Timely irrigation and high temperature weather should be ground irrigation, use all sources of water to pay attention to irrigation, to maintain the orchard soil moisture. Conditions parks should strengthen the construction of sprinkler irrigation, drip irrigation and other irrigation measures when constructing parks. In regions where water sources are insufficient and where high-temperature and drought-prone conditions are likely to occur, water management during key periods should be particularly strengthened to compensate for the lack of precipitation. The irrigation time should be before 11am and after 5pm to prevent tree and fruit burns. Liu Zhande reminded farmers that neither high temperature nor irrigation should be used to prevent phytotoxicity.
To cover the grass during the period of high temperature and drought during reasonable cover grass is an effective measure to enhance the drought resistance and water-saving cultivation of the tree. The grass in the orchard can not only reduce the evaporation of water, keep the soil moist, loose, stabilize the temperature, and protect the normal growth of the root system. It can also prevent soil compaction and weed growth, reduce the number of cultivating times, and effectively improve the microclimate of the garden.
Pruning and thinning adult trees is more tolerant to drought than saplings. Therefore, the management of saplings must be particularly meticulous. The seedlings can be properly picked up and some leaves removed to reduce transpiration. Adult trees should be properly buds, and shoots that are 40 to 50 cm long should be picked. 7 to 10 days to wipe buds, picking the heart 1 times, in order to enrich branches, aging, reduce water transpiration. In the event of continuous high-temperature weather, when the water source cannot be guaranteed, in order to avoid death of the plant, it is appropriate to increase the amount of summer pruning so as to reduce the water transpiration of the tree. The second is to remove a large number of fruits to reduce the competition for nutrients and moisture.
