1. Shelf management
In high temperature weather, it is forbidden to large-scale thinning, topping, budding and other summer pruning work in kiwifruit orchards to ensure a reasonable leaf curtain layer, maintain a leaf-fruit ratio of 5-6:1, and improve the shade of the orchard. After the high temperature is over, summer pruning work such as topping and thinning are carried out. For weak growth, young trees, etc., and bare fruits around the orchard can be shaded with shade nets.
2. Ground management
High temperature and drought, it is forbidden to clear the kiwifruit orchard, cultivate and other agricultural operations, prohibit the weeding of the tree tray, if there is no mulching, cover the tree tray or between the rows with weeds, straw, sawdust, etc., with a thickness of 5-10 cm, reduce the ground temperature of the orchard and maintain a high humidity. If the orchard is seriously short of water, it is necessary to irrigate in time, and pay attention to the time of irrigation, generally before 10 o'clock in the morning and after 6 o'clock in the evening, and it is not recommended to irrigate when the temperature is too high.
3. Foliar spray protection
In the high temperature season, amino acid foliar fertilizer and calcium fertilizer can be sprayed to improve the resistance of the tree and enhance the ability to resist high temperature. For example, 400 times of amino acid liquid fertilizer can be sprayed, sprayed once every 10 days or so, and sprayed 2-3 times in a row. The kiwifruit orchard without enlarged fertilizer can be sprayed with 0.1%-0.3% potassium dihydrogen phosphate for 2-3 times in a row, which can achieve the effect of drought resistance and sunburn prevention. It can also be sprayed with 0.01% brassinolide or 0.1% fruit and vegetable calcium fertilizer 800 times to 1000 times to enhance the stress resistance of the tree, and it is recommended to spray in the morning (before 10 o'clock) and evening (after 6 o'clock).
