Overwintering thermal sleeve for grape vine and overwintering thermal treatment method for grape vine

Abstract

The invention relates to an overwintering thermal sleeve for a vine, and particularly relates to an overwintering thermal sleeve for a grape vine. The overwintering thermal sleeve for the grape vine comprises two thermal blankets which are arranged in pairs, wherein each thermal blanket comprises an upper edge; the upper edges of two thermal blankets are detachably connected through a connecting structure; the thermal blankets are made of a polymer fiber composite thermal insulation material; and the thermal blankets are shaped like a rectangle. The invention also discloses an overwintering thermal treatment method. Upright piles and tie wires are included; the upright piles are evenly distributed in a vine land; and the tie wires are arranged between the upright piles in parallel. The overwintering thermal treatment method comprises the steps of: 1) providing the upper part of the overwintering thermal sleeve for the grape vine on the tie wires in a bestriding manner; firmly connecting the upper edges of the thermal blankets through the connecting structure; 2) stretching lower edges of the two thermal blankets, and ensuring that the lower edges at two sides are attached to the ground and horizontal edges are set apart in the horizontal direction; and 3) ridging earth on the horizontal edges at the two sides, so as to finish a thermal insulation segment. The overwintering thermal sleeve has the beneficial effects of being simple in structure, low in cost, fast to construct and good in thermal effect, and can be repeatedly utilized.

Description

technical field

[0001] The invention relates to a vine overwintering warm cover and a warming method, in particular to a vine overwintering warm cover and a wintering warming treatment method. Background technique

[0002] Because of its loose epidermis and large stomata, grape plants are easily affected by the climate in winter and spring, resulting in frostbite or air-drying. Especially in most areas of northern my country, the climate is often dry and windy, and the frostbite and air-drying damage of grape plants is more serious, which is also one of the reasons that restrict the improvement of grape planting technology. Therefore, the safe wintering of grape vines is very important in grape production. question. Whether the overwintering and cold protection technology is done well or not is directly related to the growth and development of the grapes in the following year, the level of yield and quality. In areas where the winter temperature is lower than -15°C, if no a...
