Cylindrical tree form of solar greenhouse grapes and training and pruning technology

Abstract

The invention discloses a cylindrical tree form of solar greenhouse grapes and a training and pruning technology and relates to the technology field of grape integrated management. The cylindrical tree form of the grapes is characterized in that iron wires are arranged along the top of the central lines of planting furrows of the grapes according to the cultivation pattern characteristics of the cylindrical tree form, and the iron wires are 2 m higher above the planting furrows; a plastic rope is erected at the position of a nursery stock to lead and help each of the nursery stock to grow erectly, so that trunks are formed; each grape has one trunk, and fruit-bearing branch groups are evenly distributed on the trunks, so that horizontal fruit-bearing branches are formed; the horizontal fruit-bearing branches are distributed around, so that the cylindrical tree form is formed. The tree form and the technology have the advantages that according to the tree form, apical dominance is effectively controlled, the balance between the growth and the fruit-bearing of the grapes is regulated, reserve nutrition of tree bodies is adjusted, robustness and enrichment of branches are guaranteed, so that successive years of high and stable yields is likely to happen and biennial bearing is avoided; the branches grow horizontally and are distributed in a staggered mode, so that the quality of the grapes is improved, ventilation and light are improved, plant diseases and insect pests are less likely to happen, training and pruning are more easy and convenient, and thus the production management is convenient; the tree form and the technology have further advantages of being labor-saving, time-saving, efficient and easy to spread.

Description

technical field [0001] The invention relates to the technical field of comprehensive management of grapes, in particular to the cylindrical tree shape and shaping and pruning technology of grapes in a solar greenhouse. Background technique [0002] Grape shaping is an important measure in grape comprehensive management technology. It is through the use of pruning techniques in various forms and methods, so that the backbone branches of the crown and even the branch groups are arranged in a certain form, so that the outline of the crown forms a certain shape. By selecting and forming a good tree shape, the grapes will have a firm and reasonable skeleton structure, which can balance the nutrition and reproductive growth of the tree, and improve the yield and quality of the grape fruit. In protected grape production, the traditional natural fan-shaped pruning method is generally adopted for the tree shape. The disadvantages are that the leaves and ears are mostly distributed o...

AI Technical Summary

Problems solved by technology

In protected grape production, the traditional natural fan-shaped pruning method is generally adopted for the tree shape. The disadvantages are that the leaves and ears are mostly distributed on the same shelf, the fruiting parts are concentrated, the top is strong, the top is strong and the bottom is weak, the shelf is disordered, and the fruit maturity period is inconsistent. , inconvenient management, etc.
