Cover film for grape cultivation

Abstract

The invention relates to a cover film for grape cultivation and belongs to the technical field of grape cultivation. The cover film comprises a bubble film layer and an acting film adhered to the surface of the bubble film layer, the bubble film layer comprises at least one layer of bubble film, the acting film is an aluminum laminated film or PE film, and the bubble films comprise, by mass, 80-90 parts of linear low-density polyethylene, 10-20 parts of high-voltage PE10803, 20-30 parts of metallocene 1018, 6-10 parts of anti-aging master batch and 10-20 parts of flame retardant. The cover film has the advantages of light weight, high compressive strength and tensile strength, aging resistance and the like, can be pulled and curled randomly and is convenient to construct, and then cost is lowered; when the acting film is the aluminum laminated film, the cover film is used for covering after burying of grape vine, heat insulation effect is realized, and the temperature of the coverage area can be prevented from rising; when the acting film is the PE film, the cover film is used for covering greenhouses, sunlight can be absorbed to keep temperature at a high level, accumulated snow on the cover film can disappear quickly, and coverage, heat insulation and snow removal of the greenhouses are facilitated greatly.

Description

technical field [0001] The invention belongs to the technical field of grape planting, and in particular relates to a covering film for grape planting. Background technique [0002] In the grape planting technology, in the cold season, the branches and tendrils of the grapes need to be lowered from the vines and buried in the soil, and a covering film needs to be laid on them to keep them warm. The branches and tendrils of the grapes keep growing slowly in the soil. Removing the covering film can hang the grape branches and vines on the grape trellis to grow again. At present, the covering film used for grape planting is not only heavy and inconvenient to lay, but also the covering film is easily broken and damaged after several times of curling and folding. It cannot be used repeatedly for a long time, and the replacement is more frequent. The setting cost of the covering film is relatively high. The effect of thermal insulation, therefore, required the development of a li...

Problems solved by technology

[0003] In order to overcome the deficiencies of the existing covering films, the present invention provides a covering film for grape planting, which is light in weight, easy to cover and operate, and can keep the temperature in the covered area not lower than the required temperature for the survival of grape vines, and It can prevent the cover film from absorbing a lot of heat and cause the temperature in the coverage area to be too high, and avoid the situation of early germination of grape branches caused by too high temperature
