| 摘 要： | 在推广应用旱地玉米全膜双垄沟播栽培技术基础上，从进一步减少冬春季土壤水分的无效蒸发、提高土壤含水量、改善玉米经济性状、提高玉米产量入手，进行了全膜双垄沟播秋覆膜对旱地玉米产量和降水利用率影响的试验研究。结果表明，全膜双垄秋覆膜沟播栽培可明显减少冬春季土壤水分的无效蒸发、增加土壤水分含量、玉米的经济性状明显改善，玉米产量比全膜双垄沟播栽培播种前覆膜和半膜覆盖栽培分别增产16.13%和46.08%，增产效果明显；水分生产率比全膜双垄沟播栽培播种前覆膜和半膜覆盖栽培分别提高34.5%和57.8%。

| Abstract: | In order to further diminish useless evaporation of soil water in winter and spring and increase soil moisture content,improve the economic characters of maize,increase the yield of maize,based on promoting the use of cultivation techniques of sowing dry land corn in the entire film double furrow;Research have been done on effects of planting in furrow and whole plastic-film mulching on double ridges in autumn on yield of cron production and water use efficiency in dry lands;The yield of corn production with whole plastic-film mulching on double ridges in autumn increased 16.13% and 46.08% compare with those of whole plastic-film mulching on double ridgesin before sowing and routine method of semi-mulching as well as production rate of soil water raised 34.5% and 57.8%,respectively;The result displayed that the way of planting in furrow and whole plastic-film mulching on double ridges in autumn reduced the useless evaporation of soil water in winter and spring,increased soil moisture content and economic trait of corn remarkable. |
