Agricultural daylight greenhouse orange light conversion membrane

Abstract

The invention discloses an agricultural daylight greenhouse orange light conversion membrane. A monobasic complex crystal is prepared from a nitric acid solution and europium oxide, industrial ethanol is added into the monobasic complex crystal so that an europium monobasic complex is obtained, phenanthroline is added into the europium monobasic complex so that an europium dibasic complex is obtained, the europium dibasic complex slurry is put into a vacuum suction filter and then is subjected to pumping filtration so that europium complex powder is obtained, the europium complex powder, a plastic fluorescent dye and linear low density high pressure polythene are subjected to wet processing, the product is subjected to water grinding, phase inversion, water washing and drying to form color master batches, and the color master batches are added into a middle layer of a polythene or polyolefin film according to a ratio of 2.5% so that a light conversion greenhouse film is produced. The agricultural daylight greenhouse orange light conversion membrane realizes light wave transition and promotes plant growth.

Description

technical field [0001] The invention belongs to the technical field of compounds and relates to an orange light conversion film for agricultural solar greenhouses. Background technique [0002] The growth and development of plants, flowering and fruiting all require photosynthesis produced by light. Plants have requirements on the light intensity and photoperiod of light energy, and at the same time, light quality is also a very important factor. Light quality not only affects the photosynthesis rate of crops, but also can regulate the growth of crops. It can be seen that light is an important environmental factor in the process of plant growth and development, and it is also the main energy source for plant growth. However, the absorption of light by plants is not full-band but selective. Different plants have basically the same absorption spectrum of light. Mainly concentrated in the blue light (440-480nm) and orange-red light (600-680nm) light area, which can signific...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide an orange light-converting film for agricultural solar greenhouses, which solves the problem that the light-converting films currently advertised and sold in the market only have one color difference, and cannot achieve the effect of light-converting and promoting plant growth at all.
