Small bow-shaped rain shelter frame and cultivation method for grape

Abstract

The invention discloses a small bow-shaped rain shelter frame and a cultivation method for grape. The rain shelter frame comprises a plurality of semicircular umbrella stands, wherein each semicircular umbrella stand comprises a stand column, a cross beam and a primary bow top; the primary bow top and two ends of the cross beam are welded to form a semicircle; the stand column passes through the center of the semicircle and is vertically fixed with the cross beam; the top end of the stand column is connected with the main bow top; side beams perpendicular to the frame surfaces of the semicircular umbrella stands are respectively connected between each two adjacent semicircular umbrella stands and at two sides of the umbrella stands; at least one secondary bow top is arranged between each two adjacent primary bow tops; two ends of the secondary bow tops are respectively fixed on the side beams at the two sides; and the frame surface of the rain shelter frame is formed by the primary bow tops and the secondary bow tops together. When grape is cultivated by utilizing the shelter frame, high-grade grapes can be cultivated in south rainy regions in China; the ventilation performance and the air permeability of the rain shelter frame after being covered with film can be effectively improved to ensure that the heat dissipation is fast, the humidity is low and the occurrence of diseases and pests is decreased; the root of the grape can be watered from the side by the natural rain water; and thin film removal in winter is not needed.

Description

technical field [0001] The invention relates to the technical field of viticulture and the field of agricultural equipment and facilities, in particular to a rain-proof shed for grapes and a method for cultivating grapes using the shed. Background technique [0002] In recent years, my country’s rain-shelter grape cultivation has developed rapidly. With the increase of investment and the development of cultivation technology, some grape varieties suitable for cultivation in northern regions with little rain can also be cultivated in southern rain-shelter conditions, greatly enriching the varieties of grape cultivation in the south. The purpose of rain-shelter cultivation of grapes is to avoid rainwater from wetting the grapes and reduce the occurrence of grape diseases. At present, there are many kinds of grape rain shelters in my country, such as multi-span greenhouses, single-span greenhouses, and simple sheds. Japan is an early country in the cultivation of rain-shelter...

AI Technical Summary

Problems solved by technology

[0003] The rainy areas in southern my country have high temperature and high humidity in summer, and thunderstorms are often accompanied by strong winds. However, multi-span greenhouses, single-span greenhouses, and simple small sheds have weak wind resistance and are easily damaged in summer storms, and the interior of multi-span greenhouses and single-span greenhouses is ventilated The air permeability is poor, the temperature inside the shed is much higher than that outside the shed in summer, and the high temperature and high humidity inside the shed lead to some unique pests and diseases in the shed. In addition, due to the long-term lack of rainwater leaching in the shed, the surface soil returns to salt, which affects the mineral quality of the grapes. absorption of nutrients

[0004] At present, in the cultivation of rain-sheltered grapes in southern my country, multi-span greenhouses and single-span greenhouses are used. After the rain-sheltered scaffolding is covered with film, the ventilation and air permeability in the shed is poor, and the temperature in the shed is too high in summer high temperature seasons. Photosynthetic products delay grape coloring and delay ripening, making it difficult to ensure the inherent quality of grapes; due to poor air permeability in the shed, the humidity in the shed is increased, resulting in the occurrence of unique pests and diseases in the shed; a large number of aerial roots of grape branches are produced

In addition, the existing rain shelters have weak wind resistance and are easily damaged during storms
