Embodiment 1

[0024] Light-changing agent preparation: with high-purity Mg 3 (PO 4 ) 2 、SmPO 4 ·H 2 O, NaF, Eu 2 o 3 and MnCO 3 As raw material, according to the chemical formula Mg 8.47 SmNa(PO 4 ) 7 F: 0.01Eu 2+ , 0.03Mn 2+ The stoichiometric ratio of each raw material is weighed; then the obtained raw materials are fully ground in an agate mortar and mixed evenly, and the obtained mixture is put into a corundum crucible, and then the corundum crucible and the mixture are put into a high temperature tube furnace Carry out burning, the burning temperature is 1200°C, the burning time is 6 hours, and the sintering atmosphere is a mixture of 5% hydrogen and 95% nitrogen. After the burning is completed, the sample is cooled to room temperature with the furnace, and finally the sintered body is taken out for further processing. The light-changing agent can be obtained by ball milling, pulverizing, washing and drying.

Abstract

The invention relates to the field of agricultural greenhouse planting, and in particular to a light conversion film suitable for vegetable greenhouse planting and a preparation method thereof. The light conversion film suitable for vegetable greenhouse planting is prepared from thin-film resin, a modifying agent and a light conversion agent, wherein the mass of the light conversion agent is 0.5 to 1.0 percent of the mass of the thin-film resin; a chemical general formula of the light conversion agent is Mg9-x-ySmNa(PO4)7F:xEu<2+> and yMn<2+>, wherein a value of x is greater than or equal to 0.01 and smaller than or equal to 0.03, and a value of y is greater than or equal to 0.02 and smaller than or equal to 0.05. The light conversion film disclosed by the invention is capable of assistingfarmers in improving production conditions according to a required best red light and blue light ratio during a production process of Chinese chives, so that the quality and the yield of a plant canbe increased; meanwhile, the growth period can be shortened, income can be increased, and remarkable economic benefit and remarkable social benefit can be generated.

Description

technical field [0001] The invention relates to the field of agricultural greenhouse planting, in particular to a light conversion film suitable for vegetable greenhouse planting and a preparation method thereof. Background technique [0002] Modern crop cultivation uses a lot of pesticides, chemical fertilizers, hormonal drugs and genetically modified methods, so it has also brought many diseases to humans. According to data, the possibility of pesticides and chemicals causing cancer is very high. Hormonal drugs and genetically modified It may also lead to premature development of human beings and some unstable factors. At the same time, pesticides and chemical fertilizers have also brought devastating blows to other organisms. [0003] The existing organic health food cultivation is basically based on ordinary greenhouses covering plastic film and applying organic fertilizers. The initial investment is large, the process maintenance cost is high, and the increase in produc...
