上海市郊南汇县近200亩温室大棚农作物在新年到来之前穿上了“新衣”。这件由上海师范大学参与研制的“新衣”是一种新型温室覆盖薄膜,已在南汇县书院镇给农作物“试穿”了两年。对照长寿无滴农膜暖棚,“新衣”第一年使西瓜增产9.5%,总产值上升14.29%;第二年使甜瓜增产9.94%,总产值上升30.87%。新型温室覆盖农膜的新就在于它加入了上海师大生命与环境科学学院研制的稀土转光粉。这种稀土转光粉是生产光转换农膜的重要助剂,可以将太阳光中对农作物有害的紫外光转换成绿色植物光合作用吸收的红色光,从而有
Nearly 200 acres of greenhouse crops in Nanhui County, Shanghai’s suburbs, were put on “new clothes” before the New Year. Developed by Shanghai Normal University, this new garment is a new type of greenhouse cover film that has been cropping in for two years at the academy in Nanhui County. In the first year, the yield of watermelon increased by 9.5% and the output value increased by 14.29%. The second year increased the yield of melon by 9.94% and the output value increased by 30.87%. The new greenhouse covering plastic sheeting is that it joined the Shanghai Normal University Institute of Life and Environment Science developed rare earth turn light. This rare earth turn light powder is an important auxiliary for the production of light-transformable agricultural film, which can convert the ultraviolet light harmful to crops in sunlight into the red light absorbed by the photosynthesis of green plants, so that
