摘要
在大田条件下，以露地穴播为对照，研究了不同种植模式和不同覆膜时间对半干旱区马铃薯产量和经济效益的影响。研究结果表明，采用全膜双垄沟播技术种植的马铃薯产量和经济效益较其他种植模式分别提高9．0％-46．8％和9.2％～59．03％．是一项适合于旱作区马铃薯的高产栽培技术。
The field experiment used the cultivating methods and mulching times as the treatments, the effects on crop yield and economic efficiency of potato were studied in semiarid. The results showed that the full mulching on double ridges could increase the yield and economic efficiency of potato by 9.0%-46.8% and 9.2%-59.03% contrasted to other planting models respectively, so it is a reasonable method to increase potato yield in arid and semiarid.
