Grape vine unshelving soil-burying-free overwintering cultivation method with top grafting of cold-resistant stock

Abstract

The invention relates to a grape vine unshelving soil-burying-free overwintering cultivation method with top grafting of a cold-resistant stock, belongs to the technical field of grape cultivation andaims to solve a series of problems of time and labor consumption, cost increase, vine damage, poor grape quality, ecological environment damage and the like caused by grape vine soil burying in winter in soil burying cold resistance regions. A variety expected by top grafting (60-130cm) of a stock is subjected to fixed planting, so that the cold resistance of grape trunks can be improved; grafting variety vines are cultured in a next year, and mature vines of 50-60cm are retained in winter cutting; in a third year, before germination, the stock is bent to a same direction from 10cm before a grafting interface to form a single Guyot L-shaped tree shape, and after normal fruiting, shaping culture molding is implemented according to single Guyot L-shaped tree shapes or double- uyot L-shapedtree shapes in winter; and in winter, stock trunks are coated by white lime, all scion twigs and stocks of 10cm below grafting interfaces are wrapped by a cold resistant moistening material, and thusthe cold resistance of a scion variety can be improved. Grape vine unshelving soil-burying-free overwintering cultivation can be finally achieved.

Description

technical field [0001] The invention relates to a method in the technical field of grape cultivation in soil-buried cold-proof areas, in particular to a high-grafting technology of anti-draining and cold-resistant rootstocks, and wrapping scion branches with heat-preserving and moisture-retaining materials, so as to realize the cultivation method for grapes not to fall off the shelf and avoid burying the soil for cold-proof and overwintering . Background technique [0002] Burying soil in winter to prevent cold is an important measure for grapes to survive the winter safely in northern my country. It is also the main culprit of ecological damage, and it is also an important factor that increases production costs and reduces grape quality. In order to facilitate winter burial and cold protection, the cold-proof areas of grape burial in northern my country mostly adopt the shape of vertical dragon stem, multi-main vine fan shape and "factory" shape (inclined horizontal dragon ...

Problems solved by technology

[0003] The technical problem to be solved by the invention: the present invention aims at the deficiencies in the prior art, and provides a brand-new anti-draining and cold-resistant grape rootstock colonization for grape buried soil cold-proof areas by using high grafting of grape rootstocks that can safely overwinter and resist draining and cold , green branch high-grafting, plastic pruning and thermal insulation material wrapping and other supporting overwintering and cold protection technologies, to solve a series of time-consuming, cost-intensive, branch damage, poor grape quality and ecological environment damage caused by grapes buried in the soil in winter. The problem is to realize the cultivation of grapes in the cold-proof area without burying the soil and avoiding the cold and overwintering
