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...

Problems solved by technology

In addition, for the vineyards with older trees, it is difficult to tie them together, and it is not easy to bury them.

[0004] Another way to keep warm vines overwintering is the plastic film cold-proof method. After the vines are bound together upside down, a layer of 40cm thick wheat straw and straw is covered on the vines, covered with a plastic film, and the surroundings are cultivated tightly with soil. This treatment method is labor-intensive and consumes a lot of materials, and it is easy to cause damage to the plastic film and reduce the heat preservation effect.

[0005] There is also a method of keeping warm for vines overwintering by using a special water-retaining antifreeze smear, which is formulated with waxes, plant or mineral oils, resins, etc. as the main raw materials, and sprayed on the vines to prevent freezing. Moreover, when it is washed in rainy and snowy days, the coating of the smear will fall off, and it still cannot better keep warm.

[0006] And still do not have better, economical and practical, effective vine overwintering warming measures at present
