| Abstract: | The effect of PAL on the yield of winter wheat,water use efficiency(WUE) and nitrogen utilization efficiency(NUE) were investigated from 2008 to 2010 in Loess Plateau East of Gansu.The results showed that the yield of winter wheat increased significantly with applying higher amount of PAL under the same amount of N,and improved winter wheat yield and water use efficiency with increasing N and PAL in the experimental design of N 0～105 kg/hm2 and PAL 90～150 kg/hm2 range;NUE of applying PAL treatment were higher than that of non-PAL treatment in the same amount of N,NUE of high N application amount treatment is higher than that of low N application amount treatment at the same amount of PAL. |
