Dimensions of V-shaped horizontal grape trellis

The dimensions of the V-shaped horizontal grape trellis are 1m at the bottom and 1.2m at the top.

The selection of grape cultivation framework is very important for the adjustment of tree potential. Suitable grape trellis is beneficial to the regulation of grape trees, the formation of grape yield, the improvement of fruit quality and the labor-saving management in the field.

The main frame types in foreign countries are shed frame and hedge frame, and most of them adopt standardized frame, single vertical frame, single arm or single arm cultivation and other regular tree types, which leads to the unified position of leaf curtain and fruit and obvious boundary, which is convenient for spraying management and mechanized production. Simple pruning, large-scale cultivation, professional management, standardized production and uniform quality are the important characteristics of advanced grape production countries abroad.

For a long time, the grape cultivation racks in northern China are mainly inclined sheds and horizontal sheds. Inclined shed has the characteristics of good windproof effect and less materials, but the shelf surface is low, which is not convenient for management and mechanized operation, and there are some shortcomings such as poor grape quality uniformity and serious pests and diseases.

Especially' Xinyu' and other big red fruit varieties, the traditional greenhouse cultivation, there are some problems such as different parts of the fruit coloring, inconsistent maturity, leading to uneven fruit quality, low rate of high-quality commercial fruit, delayed maturity, reduced storage and transportation resistance and so on.

The height of horizontal scaffolding is generally above 180 cm. During the grape growing period, with the increase of the load, the surface of the trellis will sink, and there are also cases where the fruit illumination conditions are inconsistent and the grape quality is different.

Basic information

Red varieties are difficult to color and have inconsistent maturity. The new shoots of these two kinds of scaffolding cultivation grow overlapping, which requires coring and pruning many times in summer, and the cultivator needs to work with his head up, which is inefficient. Spring Festival shelves, autumn shelves, the main rattan to twist 90 degrees, easy to sprain, increase labor intensity.

In recent years, with the continuous increase of labor costs and the increase of production costs, the economic benefits of fruit farmers have declined seriously. With the development of grape cultivation techniques at home and abroad, the market competitiveness of northern grape products has obviously declined. How to improve the quality and mechanization of fruit and reduce the production cost is an urgent problem to be solved in production.
