L-蓝光膜的研究和试验

Study and Test of L -blue Light Film

本文阐述了Ｌ一蓝光膜的光学特性，它能使阳光穿透该膜后产生保持一定能差的两个光谱峰，被覆盖环境可见光增加，光质和光量符合Ｃ３类作物光合作用需要，保温性能良好。通过种植试验验证，该薄膜具有能使秧苗生长粗状，发根力强，干物质产量高，能预防早稻烂秧，增强苗体生理生化活性，提高秧苗抗逆力，促进禾苗旺盛生长，有利于早熟增产等生物效应，是一种性能优越的水稻育苗覆盖薄膜新品种。

In this paper the optical features of L-blue film are described which include improved visible light transmission,two peak values of some energy difference apart,increase of visible light under the covered environment,quality and quantity of transmitted light meeting the need by C3 crops in respect of photosynthesis,good thermal reservation,etc.Plenty data of planting experiment are collected,which indicate rice seedlings cultered under L-blue covering film are stronger,of flourishing root sprouting,higher in dry matter made,resistant to rottting,of better physiological and biochemical behavior,of better resistance to adversity,more flourishing,earlier ripening and higher in yield.All these render the L-blue film a novel high quality varlety of rice seedling culturing film.
