Special double-layer illumination rack for grape cultivation

Abstract

A special double-layer sunshine rack of grape culture application is composed of a plurality of upright posts, a first cross arm, a second cross arm, a lower threading hole, a third cross arm, a fourth cross arm, an upper threading hole and ten pulling threads. The upright posts are equidistantly fixed on grape culture ground. The four cross arms are sequentially fixed on the upright posts from the bottom up. The length of the first cross arm is 30% to 70% of the length of the second cross arm. The length of the third cross arm is 30% to 70% of the length of the fourth cross arm. The upper threading hole is positioned between the second cross arm and the third cross arm. The lower threading hole is positioned below the first cross arm. Both ends of each of the four cross arms are respectively provided with a pulling thread. Each of the upper and lower threading holes is internally erected with a pulling thread. As a double V-shaped lighting structure of 'one upright post, four cross arms and ten pulling threads' is adopted, the ratio of lighting area to floor area is 3-4, and four fruit hanging zones are provided, thus being more beneficial to grape photosynthesis and ventilation; under equivalent quality conditions, the yield can be increased by 70% to 80%, so that the sunshine rack is a quite practical grape rack.

Description

Technical field: [0001] The invention relates to a grape trellis, in particular to a grape trellis for cultivation. Background technique: [0002] Grape is a kind of vine, no matter what variety is cultivated, it must be artificially erected. At present, the types of grape trellises used at home and abroad are mainly divided into two categories: trellises and fence trellises. The common trellis types mainly include horizontal trellises, inclined Scaffolds, etc., the main types of fences are "V"-shaped frames. [0003] Horizontal scaffolding structure: the column height is 260 cm, the row spacing is 500-600 cm, each row has a row of cement columns, the column spacing is 400-500 cm, and the columns are buried in the soil 60 cm. The columns between the rows are aligned, the vertical and horizontal distances are consistent, and the tops of the columns form a plane. Steel wires are drawn vertically and horizontally on the plane of the top of the column, and the distance between...

AI Technical Summary

Problems solved by technology

The inclined scaffold is a slope frame. The main disadvantages of the scaffold are: the lighting area is small, which is equivalent to the occupied area, and the continuous spreading area is large, which is not conducive to manual pruning management and picking, and the growth of new shoots is weak. Unable to carry out standardized management production

[0005] This type of frame has the advantages of ventilation, light transmission, labor saving, and convenient management, but it has a common disadvantage: the photosynthetic efficiency and land utilization rate are not ideal enough, and the comprehensive economic benefits have not been better exerted.
