Method for close planting culture and coverage overwintering for wine grapes in cold-proof area

Abstract

The invention relates to a grape overwintering method, in particular to a method for close planting culture and coverage overwintering for wine grapes in a cold-proof area, which is characterized by comprising the following steps of: making a regenerative heat insulation cotton chemical fibber blanket; at the end of fall, pruning the common or furrow planting fence or trellis grapes, and spraying a 3 to 5-degree Brix lime sulfur mixture onto the grapes; irrigating enough overwintering water, laying down branches along the furrows of fences and trellis, braiding new annual branches on main vines, and making the climbing height of the braided branches not to exceed 30 centimeters or not to exceed 20 centimeters of the culture furrows; and covering with the regenerative heat insulation cotton chemical fibber blanket in the direction motion, wherein when a regenerative heat insulation cotton single-sided chemical fibber blanket is used, one side of the chemical fiber blanket contacts the branches, and the two sides of the blanket are spread for covering to make the two sides of the blanket equidistant to the center of a setting row; and during furrow planting, the two sides of the blanket are equidistant to the center of a setting row, the edges of the blanket are lapped into the edges of a furrow with the depth of 20 centimeters and the width between 0.8 and 1.0 meter, and 10 centimeters of soil is compacted on the edges of the blanket manually or mechanically or gravels press and seal the edges and the blanket is covered. The method has the advantages of uniqueness, low price, heat insulation, light weight, labor and time conservation, and easy coverage and winding operation.

Description

technical field [0001] The invention relates to a method for overwintering grapes, in particular to a method for overwintering in densely planted wine grapes in cold-proof areas. Background technique [0002] According to my country's grape planting and wine development plan, by 2010 the national wine grape planting area will reach 66,670 hectares. In the north, due to climate characteristics, the temperature drops quickly in early winter, the temperature rises and falls in spring, and the late frost infestation is frequent. It is required to complete the burial in early winter and unearth in spring and prevent late frost in a timely manner. It has become a "bottleneck" restricting the development of viticulture industrialization in cold northern regions. In Ningxia, more than 300,000 mu of grapes need to be buried for winter protection. The labor for burying grapes in early winter and unearthed in spring accounts for about one-third of the annual vineyard management expen...
