Suitable Combination of Water and Fertilizers for Interplanted Summer Corn under Drip Irrigation
【摘要】 麦行间套播夏玉米,采用滴灌方式和适宜灌水量、分期追肥、水肥结合、氮磷肥适宜调配等有效技术措施,全生育期追施氮(折纯N)、磷(P2O5)肥量分别保持在168~186kg/hm 2 和132~159kg/hm 2 水平时,可获取9450kg/hm 2 以上产量,水分生产效益达到1.9kg/m 3 以上,显示出良好的节水增收效益
【Abstract】 By adopting effective measures, such as drip irrigation, reasonable irrigation amount, fertilizing at special growing stages on needed, united application of water and fertilizers, suitable combinations of nitrogen(N) and phosphorus(P 2O 5), and applying N and P 2O 5 at rates of 168.0~186.0 kg/hm 2 and 132.0~159.0 kg/hm 2 respectively in entire corn season, yield of summer corn interplanted in fallow strips in winter wheat field has reached more than 9450.0 kg/hm 2, and water use efficiency over 1.9 kg/m 3. The effective measures can result in obvious effects of water saving and yield raising.
