摘　　要：试验比较了半膜平铺、全膜平铺、全膜沟播等不同覆膜方式对山旱地麦后复种西葫芦产量和水分利用效率,结果表明,全膜沟播产量为39 787.50 kg/hm2,较全膜平铺和半膜平铺(CK)分别提高7.96%、18.97%;水分利用效率为285.78 kg/(mm.hm2),较全膜平铺和半膜平铺(CK)分别提高14.02%、27.89%,且差异均达极显著水平。An experiment was carried out to study the effects of different film-covering modes of semi-film mulching, full-film mulching, full-film furrow on yield and water use efficiency of dry-land multiple cropping squash after wheat. The results showed that the yield of fullfilm furrow was 39 787.50 kg/hm2, and compared with full-film mulching and semi-film mulching increased by 7.96%, 18.97%. The water use efficiency was 285.78 kg/（mm·hm2）, compared with full-film mulching and semi-film mulching increased by 14.02%, 27.89%, respectively, and the difference reached extremely significant level.
