摘要
通过分析黄淮海地区主栽作物的水分供需规律,认为冬小麦是该区农业灌溉用水的主要消耗作物,也是该区农业水分供需失衡的主要原因,应对其种植面积适当加以控制。为促进该区农业水资源利用向良性平衡方向发展,可适当选择大麦、马铃薯、油菜等作为其替代种植作物或者在适当周期内(2年或3年)放弃一季冬小麦种植。另外,该区玉米、棉花等主栽作物水分利用局部存在供大于需的现象,有一定的节水潜力,可加强其需水规律的研究,降低灌溉定额。
This article analyzed the water deprivation discipline of the main crops in irrigation area of Huanghuaihai region.The results show that the winter wheat is the main consumer of the agricultural water resource in this area,and also the primary cause of the unbalance of the agricultural water resource supply and demand.It should be choose the barley,potatoes,canola plant to plant instead,or to give up one season plant of the winter wheat in two or three years.There is some phenomenon of water oversupply on corn and cotton in this area,the studies of water requirement of crops must be reinforced,and then it should be to cut down the irrigation norm in order to advance the virtuous cycle of the agricultural water resource.
