摘要
针对山西部分果园灌水定额偏大的问题,在山西省夹马口灌区果园,根据该地畦田规格、地形条件和实际灌水情况,利用地面灌溉水流运动模拟技术和地面灌溉灌水技术参数优化模型,对灌区三种土壤表面形态即强入渗、较强入渗、中等入渗情况下的地面灌溉的畦田长度和单宽流量等灌水技术参数进行了优化,获得三种土壤入渗类型畦灌优化的灌水技术参数,为方便用户使用提供参考依据。
Aiming at the problem of large irrigation quota in some orchard in Shanxi,the orchard located in the Jiamakou Irrigation District was taken as the research object.Based on close-end border scale,topographic conditions and actual irrigation situation of the orchard,irrigation technical parameters including close - end border length and discharge per unit width were optimized in conditions of intense infiltration,less intense infiltration and moderate infiltration by using flow simulation technology and parameter optimization model of surface irrigation.The optimized irrigation technical parameters of border irrigation of three types of soil infiltration were obtained.The results could provide reference for the convenience of users.
