Abstract: 2010-2011,and the gentle slope of the earth loess hilly upland potato planting membrane cover all double ＂a film with two years＂ no-till planting mode benefits research orientation.The results found that removed the first season with mulch,double ridges all cultivation with big ridge membrane the highest yield grow potatoes,is the preferred way to get a high yield,high yield but not necessarily high charge.Potato planting membrane cover all double ＂a film amphibious＂ no-till planting with most reduce cost and increase benefit performance,it is good to reduce production investment and improve the rate of putting into production,should be in ＂a film two season＂ cultivation of wide application.In the first quarter of demolition film,double ridge membrane cover all planting in cultivation reduce cost and increase benefit performance is poor,do not advocate in production application.
