摘要
通过灌溉水高效利用监测管理信息系统对灌区代表性站点进行土壤墒情监测,分析不同监测点位下作物灌溉用水定额和作物灌溉水效益的变化,分析结果表明,灌区各作物的灌溉用水定额均大于理论试验值,作物综合灌溉用水定额为322 m^3/亩,且滴灌条件下作物灌溉水效益大于常规灌溉,作物平均灌溉水效益为4.95元/m^3。数据表明新疆三屯河灌区现状作物还处于比较保守的充分灌溉,故灌区的综合灌溉效益较好,应适当加大高效节水面积,提高作物灌溉效益,促进作物节水增收。
Using the monitoring and management information system of irrigation water,the soil moisture of repre⁃sentative stations is monitored,and the changes of crop irrigation water quota and irrigation water efficiency under different monitoring points are analyzed.The results show that the irrigation water quota of each crop in irrigation area is greater than the theoretical test value,and the comprehensive irrigation water quota of crop is 322 m^3/mu,and the crop irrigation water efficiency under drip irrigation is greater than conventional irrigation.The average ir⁃rigation water efficiency is 4.95 yuan/m^3.The data show that the crops in Santunhe River irrigation area of Xinji⁃ang are still in conservative and sufficient irrigation;therefore,the comprehensive irrigation efficiency is better.It is necessary to appropriately increase efficient water-saving area,improve the crop irrigation efficiency,and pro⁃mote the crop water-saving and income increase.
