Coupling Effects of Waterand Fertilizer on CornYield With Drip Irrigation
Abstract:Field experimentson the coupling effect of water and fertilizer on the intercrop of summer corn with dripirrigation have been conducted. The results showed that there are 4800m3 waterper hectare of summer corn can be consumed, and applying N and P2O5at rates of 175k.hm-2 and 145k.hm-2respectively in entire corn season, yield of summer corn has reached more than 9450k.hm-2,and WUE(water use efficiency) over 1.9kg.m-3. Theeffective measures can results in obvious effects of water-saving and yield-raising.
