In July, the grape is in the period of fruit expansion and gradually matures. It is the key period for obtaining high quality and high yield within one month before harvesting. It is necessary to do a good job in the management of fertilizer and water.
Timely fertilization, replenishing nutrients generally topdress in the early stage of fruit coloring, mainly phosphorus and potassium fertilizer. The potassium sulfate three-element compound fertilizer can be selected for soil application; it can also be sprayed together by controlling the pests and diseases through the method of root-dressing and topdressing to increase the nutrition of the leaves and fruits. It can be sprayed with 0.5%~1% potassium dihydrogen phosphate solution. ~3 times. In order to improve the storage stability of grape berries, two times of calcium foliar fertilizer (such as 1000 to 1200 times of Cui Kang calcium treasure) can be sprayed continuously for one month before harvesting, which can significantly increase the calcium content of grape berries. Improve the quality of grapes and calcium storage, and also have a certain effect on the prevention of cracking.
Strengthening water management In order to ensure the quality of the grapes, it is required to strictly control the irrigation within one month before harvesting to prevent the quality from degrading. Special attention should be paid to drainage and flood prevention before heavy rain comes. For varieties that are prone to cracking, it is necessary to adopt measures such as laminating and covering grass to maintain a balanced supply of soil moisture.
