Problems solved by technology

[0003] The existing red shed film is manufactured by adding inorganic red colorant to the shed film. This red shed film has the following defects: 1. The color decay period is short, and the color will fade after 50-70 days of use, and the light conversion effect cannot be maintained for a long time; 2. 1. The quality of the light is not correct, and the crops cannot fully perform photosynthesis; 3. When the film is blown, the colorant is easy to volatilize; 4. The function is single, prone to fog droplets, short service life, poor heat preservation effect and other problems

Abstract

The invention relates to an agricultural shed plastic film, and particularly relates to a three-layer fragrant-flowered garlic. The shed plastic film provided by the invention is of a three-layer composite structure, wherein the outer layer is an anti-aging layer; the inner layer is a dripping fog disposal layer with the functions of dripping, and the middle layer is a light conversion layer formed by mixing resin, nano organic red additives and other functional additives. The agricultural shed plastic film provided by the invention has the advantages of good light quality regulating effect of the light conversion layer, small color attenuation velocity of the light conversion layer, great service life prolongation of the shed plastic film, obvious temperature preservation effect, crop pest disease and pest damage insulation and the like.

Description

technical field [0001] The invention relates to an agricultural shed film, in particular to a three-layer composite red shed film used for planting leeks. Background technique [0002] Colored shed film has not been used in my country's agricultural production for a long time, but from the perspective of use, it has the effects of increasing crop yield, improving crop quality, and reducing plant diseases and insect pests compared with colorless and transparent shed film; red shed film can Increase the temperature in the shed, promote the growth of crops, and provide the red light needed by crops. [0003] The existing red shed film is manufactured by adding inorganic red colorant to the shed film. This kind of red shed film has the following defects: 1. The color decay period is short, and the color will fade after 50-70 days of use, and the light conversion effect cannot be maintained for a long time; 2. 1. The quality of the light is not correct, and the crops cannot fully...
