摘要
对BL膜和普通白色透明膜(WH膜)培育的稻苗进行了秧苗素质及多种理化指标的对比分析研究.结果表明,BL膜培育的秧苗素质优于WH膜,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WH膜培育的秧苗.利用BL膜可以培育出壮秧,具有生产应用价值.
The quality and varied physiological and biochemical indexes of the rice Seedling, raised in both the BL membrane and the white ordinary diaphanous membrane, were analysed. We have found the quality of the rice seedlings in BL membrane is better than in the white ordinary diaphanous membrane.The chlorophyll content. photosynthctic rate, activity root systems,carbohytydrote content and amlyse activity of the rice seedling raised in the BL mermbrane are higher than that raised in white ordinary diaphanous membrane.
