Late ripening grapes
The use of fertilizers in the management of late-ripening varieties of grapes should be increased. Fertilizers should be supplemented with phosphorus and potash fertilizers. In fertilization methods, in addition to the root chase, pay attention to applying foliar fertilizer. Under normal circumstances, 25 to 30 days before harvest, 15 to 20 kilograms of each of phosphorus and potassium fertilizers are applied, and potassium dihydrogen phosphate is applied to the leaves for 2 to 3 times. At the same time, for some difficult-to-color varieties, consider laying reflective film to increase the amount of light. From the perspective of fruit food safety, we should pay attention to the safety period for the use of pesticides. The use of drugs should be stopped 20 days before the market launch of grapes. At the same time, we must do a good job of preventing birds and animals. ZHANGJIAGANG DINSHENGLIN TRADING CO.,LTD , https://www.dslhouse.com
