| 摘 要： | 本研究表明：蓝膜有提高秧苗N、P、K合量；促进秧苗干重、分蘖数、叶面积、根数增加的效应，随膜色加深效果越显著．80％透光率的蓝膜对提高秧苗素质效果最佳。还研究了不同光强、不同天气下蓝膜透光率的变化，以及蓝膜育秧的地下、地上温度状况．

| Abstract: | The results of researches indicated that rice seedlings by blue plastic film can raise the N, P, K contents of the rice plant, and can also inctease the dry weight of the plant, the tiller number, LAI (leaf area rate) ,and the root number. The deeper the blue film corlor is, the better the effects are. In the authors researck conditions, 8o% liglt penetrate of blue film is the best film to improve the gualities of the rice seedlings. |
