摘要
为研究ET管理的工程节水、农艺节水和管理节水的综合节水技术,在临县白文镇曜头村选取玉米作物的四种不同组合灌溉模式,采用区域水量平衡的方法,对不同模式下不同耗水ET的变化、作物产量、作物水分生产率及效益等方面进行分析比较,结果表明所选取的"秸秆还田覆膜沟灌"模式是比较理想的应用种植模式。在ET管理综合节水措施下,可在山西及其他适宜区域对"秸秆还田覆膜沟灌"模式进行推广应用。同时对促进区域农业和经济社会可持续发展发挥重要的示范引导作用。
In order to study the comprehensive water saving technology based on ET management, combining engineering water-saving, agricultural water saving and management water saving, four different combination irrigation modes for corn in Yaotou village of Baiwen Town, Lin County are selected, the regional water balance method is adopted to analyze the change of ET of different water deprivation, crop yield and crop water productivity and benefit under different modes. The results show that the selected ＂straw counters-field coated by furrow＂ mode is an ideal planting mode. Under the ET management comprehensive water-saving measures, the ＂straw counters-field coated by furrow＂ mode can be widespread used in Shanxi and other appropriate area. At the same time, it has important guiding effect to promote regional agriculture demonstration and sustainable economic and social development.
