摘要
通过对大田玉米全膜平作、全膜垄作沟灌、全膜双垄沟播的灌水流量、灌水定额、节水效益、作物产量以及灌前、灌后土壤含水率的研究测定,认为玉米全膜垄作沟灌技术在河西地区推广有较好的效益和前景,随着石羊河流域综合治理的实施,灌区配置水权水量的减少,发展玉米全膜垄作沟灌农艺节水技术,显得十分必要。
Field corn in the whole film flat for the whole film ridge furrow irrigation,the whole film double furrow sowing irrigation flow,irrigation quota,water efficiency,crop yield and irrigation before irrigation,after the soil moisture study determined that the Corn Film Ridge furrow irrigation technology in the Hexi Region and to promote the benefits of better prospects,with the implementation of comprehensive management of Shiyang River Basin,irrigation water to reduce water rights allocation,the development of the whole film ridge furrow irrigation of maize agronomic water-saving technologies,it is extremely necessary.
