摘　　要：微喷灌溉在辽宁西区地区迅速发展,缓解了干旱缺水对当地农业的严重影响。然而,微喷灌溉技术在辽西地区缺乏相应的灌溉制度,使得其节水灌溉效益不能充分发挥。以花生为研究对象,通过灌溉试验,确定了辽西地区花生微喷灌溉的控制灌溉制度,为指导农户灌溉提供理论依据。研究结果表明,花生在75%灌溉保证率下节水灌溉制度为:一共灌5水,全生育期灌溉定额为154mm,折算成亩均灌水量为102.7m^(3)。Micro spray irrigation has developed rapidly in western Liaoning,alleviating the serious impact of drought and water shortage on local agriculture.However,micro spray irrigation technology lacks corresponding irrigation system in western Liaoning,so its water-saving irrigation benefits can not be brought into full play.Taking peanut as the research object,through irrigation experiments,this paper determines the controlled irrigation system of peanut micro spray irrigation in western Liaoning,which provides a theoretical basis for guiding farmers'irrigation.The results showed that under the 75%irrigation guarantee rate,the water-saving irrigation system of peanut was as follows:a total of 5 water was irrigated,the irrigation quota in the whole growth period was 154 mm,and the average rrigation amount per mu was 102.7 m^(3).
