Embodiment 1

[0023] The multi-functional mulching film for turning red light and longevity light conversion is composed of base resin for mulch film and multifunctional additive components for long life light conversion; the mass fraction ratio of base resin for mulch film and multifunctional additive components for longevity light conversion is 100:3.25; the base film The resin is linear low-density polyethylene; the longevity light conversion multifunctional additive component includes: longevity component A: hindered phenolic antioxidant 1010, and the mass percentage in the red light conversion longevity light conversion multifunctional film is: 0.05%; Longevity Component B: hindered amine light stabilizer 944, the mass percentage in the multi-functional mulching film for red light conversion and longevity light conversion is 0.15%; longevity component C: phosphate antioxidant 168, in the conversion The mass percentage of red light and longevity light conversion multifunctional mulching ...

Embodiment 2

[0025] The difference from Example 1 is that the base resin of the mulching film is ethylene-vinyl acetate copolymer, and other parameters are completely the same.

Embodiment 3

[0027] The difference from Example 1 is that the mulch base resin is a mixture of linear low-density polyethylene and ethylene-vinyl acetate copolymer, and the mass percentage of the two is 30:70; other parameters are completely the same.

Abstract

The invention relates to a conversion-to-red-light long-life light transition multifunctional mulching film. The invention provides the mulching film with light transition performance and light selection function, and is composed of mulching film base resin and a long-life light transition multifunctional addition ingredient; the mass fraction ratio of the mulching film base resin to the long-life light transition multifunctional addition ingredient is 100:3.25-4.52; the mulching film base resin is linear low density polyethylene; the long-life light transition multifunctional addition ingredient comprises a long-life ingredient A, a long-life ingredient B, a long-life ingredient C, a long-life ingredient D, a long-life ingredient E, an ultraviolet light shield ingredient F and an ultraviolet ray absorption function ingredient G. According to the invention, the ultraviolet light and yellow-green light which are incapable of being absorbed by the croups can be converted to red-orange light which is incapable of being absorbed by the crops, and the crop photosynthesis is enhanced.

Description

Technical field: [0001] The present invention relates to a thin film containing polymer substances, and further relates to a red light conversion multifunctional film for longevity and light conversion. Background technique: [0002] All energy sources and main material sources of crop life activities are obtained through photosynthesis. Leaves are the organs for photosynthesis. The light energy absorbed by other pigments can only be transferred to chlorophyll to cause chemical reactions. 90-95% of the dry weight of plants comes from photosynthesis. Therefore, how to make plants maximize the use of solar radiation energy for photosynthesis has a great impact on crops. The effects of different wavelengths of light on the growth of crops Effects are different. The utilization rate of light energy of crops is very low, about 1%. It can be seen that improving the utilization rate of light energy is important to crop yield improvement. [0003] Mulch film is one of the important...
