Problems solved by technology

Overwintering methods for domestic wine grapes can make wine grapes with a tree age of 5 years survive the winter at -17.6°C, but the winter temperature in these areas is significantly higher than that in the Hexi Corridor of Gansu, so these insulation materials and methods are not enough to make the grapes in the Hexi Corridor of Gansu safe. overwinter

Embodiment 1

[0038] a. Prepare the four layers of insulation materials according to the following specifications and stack them neatly: the first layer is 75D (89g / m 2 ) Polyester filament cloth, specification 8.4×2.4m; second layer 8-12 silk (0.8-1.2mm) EVA non-drip shed film, specification 8.4×2.4m; third layer 500-700g / m 2 Needle-punched felt, size 8.0×2.0m; the fourth layer is 1.5-2.5mm thick EPE foam material, size 8.0×2.0m.

[0039] b. Fold the first layer and the second layer back to the hemming, and the length of each side hemming is 20cm.

[0040] c. After the hemming is completed, use an industrial sewing machine to hem the hem. The width of the hem is 10-15cm. After the seaming is completed, the long side is 8cm away from the sideline, and the riveted buckle is reinforced every 50cm. Sew 200×3cm Velcro on the short side at a distance of 5cm from the sideline. The front and back sides of the sticky fastener are respectively located on the front and back sides of the thermal in...

Abstract

The invention discloses a heat preservation material for covering and overwintering wine grapes in a low-temperature area and a making method of the heat preservation material. The heat preservation material is formed by connecting four layers of materials, namely polyester filament cloth arranged on the first layer, a non-drop greenhouse film arranged on the second layer, a needle punched felt arranged on the third layer and a foaming material arranged on the fourth layer. The heat preservation effect is achieved through the design of the four layers and the synergistic effect among the materials, moisture is effectively prevented from entering, and heat preservation performance is long in lasting time; mechanized operation of a volume curtain machine can be achieved through rivet clasp design and thread gluing design. According to the heat preservation material, in the production process, a rotary cultivator can be utilized to press edges, and work efficiency is greatly improved.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a thermal insulation material covered with wine grapes for overwintering in low-temperature regions. Background technique [0002] In recent years, the area of ​​wine grapes in my country has been expanding year by year. In 2010, the planting area of ​​wine grapes in China reached 6.67×10 3 hectares, it is expected to reach 100,000 hectares by the end of 2015. The Hexi Corridor in Gansu has become the best wine grape producing area in Northwest China and even in the whole country due to long sunshine hours, large temperature difference between day and night and scarce precipitation. However, the extremely low temperature in winter in this region can reach -28°C, while the lowest temperature that the European and American grape populations can withstand is -15°C, and the temperature for most varieties to survive the winter safely is only above -10°C. Therefore, the wine grapes in...
