Low-main-vine T-shaped flat canopy frame grape tree form and building method thereof

Abstract

The invention belongs to the technical field of grape tree pruning, and particularly relates to a low-main-vine T-shaped flat canopy frame grape tree form and a building method thereof. The tree form comprises a vertical trunk with the length of 1.4-1.5 m; two main vines extending in opposite directions in the horizontal direction grow at the top end of the trunk, and the length sum of the two main vines is 8-10 m; fruiting canes evenly grown on the main vines, 60-80 fruiting canes grow in each tree, and the distance between every two adjacent resulting canes is 10-15 cm; the two main vines are in the same straight line and perpendicular to the trunk, a horizontal leaf curtain is formed 30 cm obliquely above the horizontal main vines, and the whole tree form is in a T shape. The flower formation and fruit setting rate and fruit quality are improved, the tree form is the novel tree form suitable for wide-row wide-spacing planting canopy frame cultivation, operation is convenient, the labor intensity can be lowered, labor is saved, and mechanical pruning is more convenient.

Description

technical field [0001] The invention belongs to the technical field of vine shaping and pruning, and in particular relates to a vine shape and a construction method thereof for a T-shaped flat frame with low main vines. Background technique [0002] Shaping is one of the important cultivation and management measures of grapes. It can balance the vegetative growth and reproductive growth of the tree, and improve the yield and quality of the fruit. At present, the development direction of grape pruning and pruning in the world is that the trunk is changing from more to less, the leaf curtain is clear, the result is neat and consistent, the technical operation is simple, and it is suitable for mechanized operations. [0003] The tree shape used in my country's current production is basically a tree shape with narrow rows and dense branches centered on output, such as a fence with multiple main vines and a horizontal dragon trunk; a scaffold with a single dragon trunk. These tr...

AI Technical Summary

Problems solved by technology

These tree-shaped fruit parts are scattered, the fruit quality is inconsistent, the leaf curtain is not neat, the tree vigor is difficult to control, the summer pruning in production requires a lot of labor and is not suitable for mechanized pruning, the labor cost is high, and the pruning technology is complicated. Difficult to master and requires long-term guidance from a technician

[0004] With the implementation of large-scale agricultural planting in the country, vineyards in the form of small farms have developed rapidly. However, in recent years, the rural labor force has become scarce, and labor costs have continued to rise.

At the same time, the current dense planting of hedges is not suitable for mechanized pruning, and requires a large amount of labor; scaffolds are generally high, and pruning requires ladder assistance, and labor efficiency is low. Therefore, it is urgent to appear wide rows, sparse planting, labor-saving, and standardized tree shapes.
