坡耕地地膜小麦栽培技术研究初报

近年来,黄土高原坡耕地农作物产量随农业科技的普及推广,有了大幅度的提高,但在长期干旱的情况下,如何更有效地蓄存和利用有限的天然降雨,使占黄土高原总面积70%的坡耕地农业作物产量达到稳产高产,显得更为重要.坡耕地地膜小麦不仅解决了作物的稳产高产,而且充分利用了天然降水,提高了水分利用率.1996～1997年试验表明,坡耕地地膜小麦每公顷产量可达4132.5kg,同时该栽培技术投资少、见效快、简便易行,不仅为就地拦蓄入渗,减少坡面径流起到重要作用,而且更重要的是为黄土丘三区坡耕地小麦的栽培开辟了新的途径.

The Culture Technology of Plastic Film Wheat in Slope Field

With the agricultural scientech popularization,the crop yield increased greatly.However,it is very important how to use and store the limited precipitation and to carry outcrop high-stable production in Loess Plateau with 70% slopeland.The culture of plastic filmwheat might promote the crop high-stable production and use the precipitation effectively.The 1996 and 1997 research data had suggested the yield of plastic film wheat might arrive at 4132.5kg/hm².Because of low invest,high income and simple pulture,the culture technologyof film wheat with storing runoff and reducing water loss had spread over 3rd sub-region ofLoess Plateau.
