Summer pruning method of grapes

A pruning method and grape technology, applied in the application, cultivation, agriculture and other directions, can solve the problems of not following the law of grape growth and development, the contradiction between fruit yield and quality, and the weakening of tree vigor, so as to improve the quality of flower bud differentiation and improve the tree body. Disease resistance and fruit quality improvement

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.

Embodiment

[0013] like figure 1 As shown, it is a schematic diagram of the summer grape pruning method used in this embodiment. As shown in the figure, the grape clusters in the figure represent the flower and fruit ears, and the cross marks in the figure represent the pruning parts.

[0014] As shown in the figure, there is a flower spike growing on the fruiting branch 1, and only one flower spike is kept on each fruiting branch, and if the fruiting spike is above the node position (excluding the leaves with the same height as the flower spike) the fourth leaf When unfolding, top off the fruiting branches to prevent excessive growth of branches and consume nutrients. Then, all the side branches 2 on the opposite side of the flower spike and the lower nodes are removed, so that the nutrient consumption is saved, and the ventilation and light are transparent; Pruning; the side branch 4 on the result branch 1 and the first side branch 3 retains a leaf and picks the heart (note: the same l...

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...
