摘要 双光水稻壮秧膜采用聚乙烯共混改性,利用光转换机理,通过添加光转换剂来改善薄膜的透光特征,提高蓝紫光、红光的透过率及紫外光的吸收率,使其更适合水稻秧苗生长的需要。研究表明,双光膜培育的秧苗的叶绿素含量、光合速率、根系活力、碳水化合物含量及淀粉酶活性均高于普通膜培育的秧苗。 Bi-light PE film for rice seedling was modified with a light-conversion agent. Taking advanrage of the optical conversion characteristics, the film allowed blue-violet and red light to transmit, UV to be highly absorbed. The light spectrum in such film became more suitable for the growth of rice seedlings, better than in the white ordinary diaphanous film. The chlorophyll content, photosynthetic rate, activity root systems, carbohydrate content, and amylase activity of the rice seedling raised in the bi-light film were all higher than those in the white ordinary diaphanous film.
