Grape safety wintering method

Grasp the cold resistance of grape vines, grape roots hibernation temperature should be maintained at minus 6 degrees Celsius above, this temperature is a safety indicator of vines not frozen.

Pay attention to the timely pouring of frozen water 10 days before the winter vines are buried in the cold-proof soil, the whole garden is sprayed with general tree-protection and irrigated once to freeze the water. Its purpose is to prevent root freezing damage and drought in early spring. When irrigation, it is necessary to fill the soil. When the soil reaches a saturated state, it should be buried and kept cold when the soil on the ground is slightly dry.

Note that taking land points and back-sealing trenches to prevent the cold soil must be taken between the two sides of the vine's trunk, and must not be too close to the roots, so as not to damage the roots and frozen roots. Where there are irrigation conditions, the trenches should be filled with water and frozen into ice after being frozen. This will not only reduce the thickness of the frozen soil, but also help the roots to overwinter and late spring drought. Where there is no irrigation condition, weeds and other items can also be used to cover the trenches to prevent the grapes from freezing.

When it is found that cracks appear on the cold-proof soil after entering winter, cracks shall be used to cover the cracks in time from January to February. In particular, when the weather is particularly cold, spray a tree maintenance general and pile some fireweed or horse dung on the cold soil. And other cold-proof materials to ensure that the grapes are not frozen.
