Grape growth management technology

During the growing period of the grape, the top of the new shoot is removed, which can inhibit the growth of the apex. Topping the flowers before flowering can transfer the assimilated nutrients to the inflorescences more, promote the growth of inflorescences and flower development, reduce the falling flowers and fruit, and increase the fruit setting rate. Varieties with low natural fruit setting rate, such as rose scent and jumbo, should be carried out 1 week before flowering, and it is more suitable to leave 7 leaves above the inflorescence. Generally, the wine grape has a higher fruit setting rate, the ear is small, and the topping is not performed separately, and the new shoot is often carried out simultaneously. Grapes cultivated on scaffolding can be used to extend the tip of the leaves to 15 to 20 leaves, and other new shoots leave 8 to 12 leaves for topping. Linyi Fertilizer Network Copyright
