Influences of Different Nitrogen Fertilizer Rates on Yield of Xiangzaoxian45

The influences of different nitrogen fertilizer rates on the yield of Xiangzaoxian45 were studied through the field plot experiment.The results showed that different nitrogen fertilizer rates had huge influences on the yield of the Xiangzaoxian45 that it was positively correlated with the nitrogen fertilizer increasing to 180 kg/hm2 and reduced with the nitrogen fertilizer exceeding the 180 kg/hm2.Comprehensively analysis indicated that the Xiangzaoxian45 got the highest yield and benefit when the nitrogen fertilizer rate was within 180 kg/hm2.
