Summer pruning method of grapes

Abstract

The invention discloses a summer pruning method of grapes. The method comprises the following steps: (1) pruning each bearing branch (1) to preserve a spica; (2) if a fourth leaf above each section on which the grape spica is located is unfolded, pinching the corresponding bearing branch (1); (3), pinching all side branches (2) at the opposite side and the lower section position of the spica; (4) pinching if six leaves are grown on a first lateral branch (3) above the same side of the spica; pruning an upper lateral branch (4) of the first lateral branch (3) to preserve a leaf and pinching; pruning a topmost lateral branch (5) to preserve 2-3 leaves and pinching; keeping a leaf on each of the rest lateral branches respectively and pinching. By adopting the summer pruning method of grapes provided by the invention, the flower bud differentiation quality can be improved, the yield can be improved, the fruit quality can be improved, the advanced manuring of fruits can be promoted, and the disease resistance of trees can be improved.

Description

technical field [0001] The invention relates to a grape pruning method in summer, which belongs to the technical field of agricultural production. Background technique [0002] Summer is an important period for the growth and maturity of grape fruit, and it is the core period of year-round management. The focus of management is to coordinate the balance between vegetative growth and fruit growth, achieve ventilation and light transmission, inhibit the occurrence of diseases and insect pests, save water and fertilizer, and improve fruit quality. However, in actual production, there is randomness in summer pruning (removing germination, fixing shoots, topping) and does not follow the law of grape growth and development. Growers carry out pruning based on experience and have not formed a scientific and reasonable pruning method, resulting in a discrepancy between fruit yield and quality. The contradiction between them is prominent, the tree vigor is weak, the pests and disease...

Problems solved by technology

However, in actual production, there is randomness in summer pruning (removing germination, fixing shoots, topping) and does not follow the law of grape growth and development. Growers carry out pruning based on experience and have not formed a scientific and reasonable pruning method, resulting in a discrepancy between fruit yield and quality. The contradiction between them is prominent, the tree vigor is weak, the pests and diseases are frequent, and the quality of flower bud differentiation is reduced.
