Method for removing off grapes from shelves and overwintering without being covered with soil

Abstract

The invention relates to a method for removing off grapes from shelves and overwintering without being covered with soil. The method comprises the following steps: 1 after removing off the grapes from the shelves at autumn, collecting grape branches and tendrils and sequentially planting and placing flatly; paving a special grape soil-burying-free cold-proof quilt and pressing the two sides by using the soil, wherein the special grape soil-burying-free cold-proof quilt is in a three-layer structure and comprises a heat-insulation layer which is used as a cold-proof quilt main body; a protective layer and a moisture keeping layer are arranged on the upper and lower surfaces of the heat-insulation layer respectively; 2 when the spring of the next year comes and the air temperature is raised and is 10 DEG C, opening the two sides of the cold-proof quilt to form small openings at an interval of 4m-5m to ventilate; 3 when the air temperature is stable at more than 15 DEG C, enabling grape bud eyes to germinate and completely removing off the cold-proof quilt; putting the recycled cold-proof quilt on a wide place to be aired; winding and binding the cold-proof quilt into a storage to be stored. According to the method provided by the invention, not only can the production cost be reduced, but also the problem of blowing and raising sand is solved, so that the method has very important meanings to grape planting industries.

Description

technical field [0001] The invention relates to a method capable of realizing that grapes can be removed from shelves in winter without being buried in soil for overwintering. Background technique [0002] Grapes occupy an important position in the production of fruit trees in my country and even in the world. At present, my country's grape planting area is 8.2 million mu, with an output of 8.55 million tons, ranking second in the world. Fresh grapes rank first in the world, accounting for the world's fresh food 23.5% of the total grape production. my country is the only country in the world that adopts buried soil for cold protection in grape cultivation, and the dominant grape production areas are all in buried cold protection areas and desertification areas. In order to ensure the safe overwintering of the grapes, the traditional cold protection method is to remove the shelves and bury them in the soil in winter. The specific operation is: after the grapevines are cut off...

AI Technical Summary

Problems solved by technology

These cold protection methods can protect grapes from freezing damage to a certain extent, and reduce and reduce production costs and the phenomenon of sand and sand, but they have not fundamentally solved the problem. Although the cold protection measures of plastic film + straw have solved the problem of sand and sand problems, but compared with burying the cold, it does not reduce the production cost, and it also provides a new way for the invasion of germs, and its heat preservation effect is relatively poor
