【摘要】：通过熔融插层法制备了具有光转换功能的纳米聚乙烯薄膜,用XRD、UV-Vis、FL、TGA等方法对转光膜的性能进行了分析研究,结果表明新型纳米转光膜能有效地吸收对植物有害、对温室棚膜有破坏作用的206~360nm的紫外光,发射360~500nm的蓝紫光,且其具有良好的抗荧光衰减性能。转光膜在红橙光和蓝紫光区的光质比例分别比对照高2.43%和1.82%,有利于植物进行光合作用,且在UV-A、UV-B、UV-C光区的光质比例分别低于对照1.35%,4.97%,5.54%,这在一定程度上会降低紫外线对塑棚温室内作物及棚膜的损害。与对照膜相比,纳米转光膜有良好的保温性能,且可有效提高塑棚温室内的空气温度和土壤温度,利于作物生长,农田试验结果表明,新型纳米转光膜可有效促进生菜的生长,用其处理的生菜鲜重比对照增加了14.03%,可有效提高作物的产量。
[Abstract]:Nano-polyethylene film with light conversion function was prepared by melt intercalation method. The properties of the film were studied by XRD,UV-Vis,FL,TGA and other methods. The results showed that the new nano-conversion film could effectively absorb harmful to plants. The UV light of 206~360nm, which is destructive to greenhouse film, emits blue ultraviolet light of 360~500nm, and it has good anti-fluorescence attenuation performance. The ratio of light to quality in the region of red orange and blue violet light was 2.43% and 1.82% higher than that of the control, which was beneficial to the photosynthesis of plants, and the ratio of light and quality in the light region of UV-A,UV-B,UV-C was lower than that of the control 1.35, respectively. 4.975.54, which can reduce the damage of ultraviolet ray to the crops and film in plastic greenhouse to some extent. Compared with the control film, the nanometer light transfer film has good thermal insulation performance, and can effectively improve the air temperature and soil temperature in plastic greenhouse, which is conducive to crop growth. The results of field experiments show that the new nanometer light conversion film can effectively promote the growth of lettuce. The fresh weight of lettuce treated with it was increased by 14.03 as compared with the control, which could effectively increase the crop yield.
