First, spray calcium in time. Bagging fruit is prone to calcium deficiency, and has a great impact on fruit quality and storage. Generally, it is necessary to spray 2-3 times of high-quality CA2000 calcium or calcium or calcium calcium or ammoniacal calcium before bagging. If the number of sprayed calcium is insufficient, use a spray of high-quality calcium fertilizer after the bagging, and then spray the calcium fertilizer again after removing the bag.
Second, increase phosphorus and potassium fertilizers. The sugar content of the bagged fruit is generally lower than that of the bagging and the taste is lighter. In July, 0.5-1 kilograms of phosphorus and potassium fertilizer were applied to each plant, and CA2000 Guoyangbao or Qirui amino acid, ammoniacal calcium and other foliar fertilizers were added in combination with spraying.
Third, continue to cut in the summer. In the summer of high temperature and drought, bagged fruits are prone to sunburn. Therefore, in the summer, the branches on the back and the dense branches must be properly removed.
Fourth, water hole. After bagging, if the temperature is too high, water should be poured. If the orchard with incorrect bagging method and ventilation hole is not open, it should be inspected and the air hole should be manually cut to reduce the temperature inside the bag. For plastic bags orchards, in the high temperature, high humidity season after the wind, after rain, to prevent the bottom of the film bag wrapped around the fruit surface, once found to immediately flatten the bag, show.
Fifth, strengthen pest control. Although bagging fruits can reduce the occurrence of pests and diseases, but the occurrence of serious pests and diseases, should pay attention to spraying control in July-August.
