本文从1982—1984年连续3年在集安县头道乡进行了蓝色塑料薄膜和无色薄膜培育水稻秧苗的试验,观察不同颜色薄膜对水稻秧苗素质的影响。通过试验我们认为蓝色比无色塑料薄膜培育的秧苗素质好,叶绿素含量增加,干物重和发根力明显提高。平均每亩增产39斤,而蓝色膜比无色膜每亩节省114.5元。 In this paper, blue plastic film and colorless film were used to cultivate rice seedlings in Tudao Township, Ji’an County for three consecutive years from 1982 to 1984, and the effects of different color films on the quality of rice seedlings were observed. Through experiments, we think that the quality of blue seedling is better than that of colorless plastic film, the content of chlorophyll is increased, the weight of dry matter and the hair rooting power are obviously increased. An average of 39 kg per mu yield, while the blue film than the colorless film saved 114.5 yuan per mu.
