A New Method to Simplify Cold Protection of Grapes

Abstract

The invention relates to a simplified grape cold prevention novel method. According to the invention, soil is covered on grape roots for preventing cold, and the method is determined according to local winter temperature extremum. Specifically, each year before soil freezing or when the temperature reduces to 0 DEG C, root cold prevention is carried out upon grapes: soil between grape lines are dug and used for covering the two sides of grape main trunks, wherein a soil layer with width of 50-80cm and thickness of 20-30cm is coated on both the left and right sides of a grape main trunk (on the two sides of grape main trunks between lines). The method is simple to operate. With the method, processes for detaching and attaching grapes to trellis are eliminated, such that the damage to tree branches is avoided, and a soil burying cold prevention process is greatly simplified. Also, the occurrences of soil-borne diseases can be reduced.

Description

1. Technical field The invention relates to a novel method for simplifying the overwintering and cold protection of grapes, which belongs to the field of viticulture. 2. Background technology In the grape producing areas in northern my country, freezing injury in winter is the key ecological factor affecting the sustainable production of grapes. In areas where the absolute low temperature in winter is lower than -15°C, the traditional production method to avoid freezing damage is to remove the grapes from the shelves and bury them in the soil to prevent the cold. Although the overwintering effect of burying the cold is remarkable, but the operation process is cumbersome. Every year, it needs to be removed, buried, unearthed, and put on the shelf. The money spent on burying the cold and preventing the cold accounts for 1 / 4-1 of the annual production cost of the entire vineyard. / 3. Putting grapes on and off the shelves is not only troublesome, but also causes mechanical dam...

AI Technical Summary

Problems solved by technology

The current method of burying grapes to prevent cold is to bury the whole plant in the soil together, which requires a lot of labor and is difficult to mechanize. Moreover, due to the large size of the tree above the ground and the large gaps, the engineering of soil extraction, burial and removal of soil is huge. Therefore, in many cold regions, the thickness of the buried soil is insufficient, and the protection of the root system is not effective, which often causes freezing damage to the plants, especially the root system. The idea, that is, the key to winter cold protection of grapes is to ensure that the root system does not suffer from low temperature damage
