一地膜覆盖裁培技术,从1979年引进到现在(1986年)仪北方六省(辽、鲁、豫、冀、京、陕)覆膜栽培面积已达370余万亩。经过科研、单位院校和农技推广部门试验、示范、推广的实践证明,这项栽培技术,由北向南,由东到西,在我国花生生产发展中,发挥了巨大的作用。在无霜期长、温量资源充沛的黄淮、长江流域中游地区,为了提高复种指数,增加经济效益,麦茬覆膜夏播花生得到发展,赢得粮油双丰收.在长江中游的湖北、湖南、安徽、江西等水稻产区应用地膜覆盖新技术,推行粮油轮作,已获得新进展。如中国农业科学院油料作物研究所,自1983年起,针对当前、当地农业生产的需要,先后与上述四省农业厅协作开 A film mulching cultivation technology, introduced from 1979 to now (1986) north of six northern provinces (Liao, Shandong, Henan, Hebei, Beijing, Shaanxi) covered cultivation area has reached more than 370 acres. After scientific research, unit institutions and agricultural extension departments to test, demonstrate, promote the practice has proved that this cultivation technology, from north to south, from east to west in China peanut production and development, has played a huge role. In the areas of Huanghuai and the middle reaches of the Yangtze River where frost-free period is abundant, and the middle reaches of the Yangtze River valley, summer peanut covered with wheat stubble has been developed in order to increase the multiple cropping index and increase economic benefits, Jiangxi and other paddy areas to apply new technology of mulching, grain and oil rotation, has made new progress. For example, the Institute of Oil Crops, Chinese Academy of Agricultural Sciences, since 1983, in response to the current and local needs of agricultural production, has collaborated with the above four provinces Agriculture Department
