摘要
2010～2011年，在黄土丘陵缓坡地上对旱地马铃薯全膜双垄覆盖“一膜两年用”免耕栽培模式效益进行定位研究。结果发现，拆除第1季地膜，双垄全膜覆盖栽培大垄侧种植马铃薯产量最高，是获得高产的首选方法，但高产不一定能高收；马铃薯双垄全膜覆盖“一膜两年用”免耕栽培最具有节本增效性能，它能很好地减少生产投入，提高投产比，应在“一膜两季”栽培中大面积推广应用；拆除第1季地膜，双垄全膜覆盖沟播栽培节本增效性能最差，生产中不提倡应用。
Effectiveness localization of double ridge mulching in upland potato under non-tillage cultivation mode of ＂one film used for two＇years＂ was studied in gentle hill of loess hilly from 2010 to 2011. The results showed that after the first season mulch was removed, the potato yield in double ridge mulching cultivation was the highest, which was the preferred method to obtain high yield, but high yield was not necessarily led to high income. Double ridge mulching under non-tillage cultivation mode of ＂one film used for two years＂ performed better cost saving and benefit improving ability, which could better reduce production investment and improve production ratio, and should be promoted in large area in ＂one film used for two years＂ cultivation： The cost saving and benefit improving ability of double ridge mulching and furrow sowing cultivation was the poorest after the first season mulch was removed, so the procedure is not advocated in the production.
