摘　　要：基于北方旱区'十年九旱'、'十田九旱'的地域特点和'春旱秋雨'的气候特征,提出'在旱平地上,结合作物播种,采用双沟覆膜技术,在4～9月份集雨聚水、截流蓄存,实现多雨时蓄水,天旱时补灌'.这不仅大幅度提高了雨水的利用率,增进了农田水分的生产潜力,而且有效地遏制了因地表径流引起的水土流失等现象.The film-covered double-furrow planting technique on even drought land was put forward based on the characteristic of nine drought year of decade on north drought areas and the climate feature of spring dry and autumn rain. The technique comprised film covered Double furrow cultivating plant, collecting rain and gathering water, capturing glide and storing up in order gather water in rain and irrigate in drought from April to September. The technique is not only improved the water utilizing efficiency and in creased cropland water production potential, but also kept within limits the water and soil lose through water flow in land surface.
