Grape overwintering covering structure and manufacturing method as well as use method

Abstract

The invention discloses a grape overwintering covering structure and a manufacturing method as well as a use method. The structure is of a multilayer structure and comprises a piece of waterproof cloth, a greenhouse film, a felt, industrial cotton and another piece of waterproof cloth from bottom to top in sequence. The manufacturing method comprises the steps of smoothly laying the waterproof cloth, the greenhouse film, the felt, the industrial cotton and the other piece of waterproof cloth from bottom to top in sequence, cutting out according to required length and width, and then stitching all layers together through needlework along the circumferences. The use method comprises the steps of hilling up at both sides of a base of a grape main stem, so as to form a grape valley with the width of 110 to 120 cm and the depth of 20 to 30 cm, pressing grape branches and tendrils into the valley, cover the grape valley with the overwintering covering structure, and then compressing, so that a certain space is formed in the grape valley. The grape overwintering covering structure has the effects that the water content of the grape branches can be effectively increased in the period of dormancy, so as to prevent the branches from losing water and drying and prevent grape roots and the branches from being frozen; when the temperature rises in spring, the temperature rise in the covered grape valley is slower than that in a soil buried overwintering grape valley due to a covering effect, and grapes delay germinating, so that the capability of preventing late frost is effectively increased.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and relates to a grape overwintering covering structure, a manufacturing method and a using method. Background technique [0002] In recent years, the grape industry in Northwest my country has developed rapidly and has become a pillar industry for farmers to increase their income and get rich. The temperature in Northwest China is low in winter. After pruning, the branches of the grapes will suffer from frost damage and dehydration if they are completely exposed to the air. Therefore, cold protection treatment is required. At present, grapes in Northwest China generally use buried soil for overwintering, which has high labor input costs, difficulties in seasonal labor, poor ability to prevent late frost, and serious dehydration of grape branches. Although plastic film and straw curtains are used in some areas to cover the winter, there are also problems such as inconvenient operation and ...

AI Technical Summary

Problems solved by technology

At present, grapes in Northwest China generally use buried soil for overwintering, which has high labor input costs, difficulties in seasonal labor, poor ability to prevent late frost, and serious dehydration of grape branches.

Although plastic film and straw curtains are used in some areas to cover the winter, there are also problems such as inconvenient operation and non-reusable use, which not only increases the cost of base construction, but also affects the quality of grape base construction. Therefore, it is urgent to explore a new type of covering material. To replace the existing buried cold winter
