应用0.1mm厚度塑料薄膜(简称普膜)进行早稻保温育秧,能起到增加复种指数、扩大粮食播种面积、进一步提高早稻、后季稻单位面积产量的作用。但普膜价格高,农本大、经济效益低。我县从1981年起,在三熟制早稻秧田上用0.015mm厚度塑料薄膜(简称地膜),进行了小面积育秧试验,取得了较好的效果。1983年推广面积达6800余亩,占 The use of 0.1mm thick plastic film (referred to as the general film) for early rice incubation and seedling can play a role in increasing the multiple cropping index, expanding the sown area of ​​grain, and further improving the unit area yield of early and late rice. However, the high price of Pu membrane, agricultural capital, low economic benefits. Since 1981, we have experimented on a small-area seedling raising experiment with plastic film of 0.015mm thickness (referred to as plastic film) on the three-year-old early rice seedling and achieved good results. In 1983 to promote the area of ​​more than 6800 acres, accounting for
