主题词:旱地双沟覆膜集雨节灌技术是一项综合抗旱耕作技术,适合在粮、油菜等经济效益较高的作物上应用,具有集水、渗水、保水和节水多种功能,且具有投入少、易操作、等特点。地处毛乌素沙漠与黄土高原过渡地带的榆林,年降雨量400mm左右,素有“十年九旱”和“十田九不收”的说法,在科学技术高度发达的今天,干旱依然是困绕当地农业发展的主要因素。2001年,农业技术人员在学习借鉴各地旱作农业技术的基础上,通过大胆试验示范和技术创新,将地膜
Key words: Dryland double-furrow catchment rainwater harvesting technology is a comprehensive drought-resistant tillage technology suitable for crops and rapeseed with higher economic benefits, such as catchment, water seepage, water retention and water saving, And with less investment, easy to operate, and so on. Located in the transition zone of the Mu Us desert and the Loess Plateau Yulin, annual rainfall of about 400mm, known as “ten years nine drought ” and “ten fields nine do not accept ” argument, science and technology are highly developed today, drought It is still the main factor that has troubled the development of local agriculture. In 2001, on the basis of learning and drawing on the technologies of dry farming in various places, agricultural technicians, through bold experimental demonstration and technological innovation,
