采用试验、验证、示范相结合的研究方法，把玉米全地面地膜覆盖栽培技术的节水增产效果与常规条膜覆盖和露地优化栽培进行了比较，浅析了此项栽培技术的节水增产原因及经济效益问题，肯定了全膜覆盖的节水增产增效作用，为干旱地区玉米生产再上新台阶提供了理论依据。 By using the methods of experiment, verification and demonstration, the water-saving and yield-increasing effect of corn ground-covered mulching cultivation technology was compared with the conventional strip-mulching and field-optimized cultivation. The reason of water saving and yield increase of this cultivation technique was analyzed And economic benefits, and affirmed the water-saving and yield-increasing effect of full film coverage, which provided a theoretical basis for the corn production in arid areas to a new level.
