| 摘 要： | 针对陇东旱作农业区年降水量少、季节分布不均，特别是玉米生产中春旱严重等问题，研究了6种不同覆膜方式对旱作玉米水分利用效率、土壤水分变化、生育时期、出苗率、产量及经济效益的影响。结果表明，双垄面全膜覆盖沟播种植技术能够把小于5mm的无效降水蓄积起来，最大限度地减少了玉米棵间蒸发，提高自然降雨的利用效率，提高出苗率和出苗速度，提早成熟，增产效果明显，经济效益显著，是陇东旱地玉米有效的抗旱覆膜方式。

| Abstract: | In order to meet of water requirement of maize grouwth at the situation of limited and unevenly distributed rainfall in Longdong dry farming area,the problem of serious spring drought,the effects of six different film-covering modes on emergence rate,growth stages,water use efficiency,soil moisture variation,yield and economic benefit of dry land maize were studied.The results showed that the mode of whole covering on double ridges and planting in catchment furrows was a most effective film-covering mode fo... |
