摘　　要：以民勤绿洲主要作物为研究对象,通过TDR土壤水分测定仪及作物生长、耗水等指标常规测定方法测定了不同节水灌溉条件下作物耗水规律、产量效应、水分利用效率及经济效益,并结合气象数据比较不同灌水处理的优越性,提出了包括耕作、灌水、用水全过程的主要作物节水灌溉模式。研究结果表明,这些集成模式在不减少主要作物产量的同时可有效抑制土面无效蒸发、降低灌溉定额、提高水分利用率及经济效益。Taking the main crops as the research object in the Minqin oasis,through TDR soil moisture measuring meter and conventional method,this paper measured water consumption rule,production effect,water use efficiency and economic benefit under different water saving irrigation conditions.Combining meteorological data to compare the advantages of different irrigation treatments,this paper put forward water saving irrigation mode of main crops,including the overall process of cultivation,irrigation and water use.The result shows that the integrated model can inhibit the soil surface invalid evaporation,reduce irrigation quota,increase water use efficiency and economic benefit.
