【摘要】 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。更多还原

【Abstract】 The integrated method of experiments,trials and demonstrations wasadopted to compare the effects of maize yield-increasing and water-saving cultivationtechnclogy by the whole ground plastic sheet mulching with that of the traditional stripplastic sheet mulching and the cultivation of corn without mulching.This paper analysedthe yieldincreasing catises with water saving by this technology and economic returns as well,thus confirming the effect of the whole field plastic sheet mulching in yield increaseso that a scientific base was provided for increasing maize yields in a new stage in thearid areas.更多还原
