| Abstract: | Objective] To study the influence of different nitrogen application amount on the physiological and growth characteristics of Guiliangyou 2.Method] A randomized block experiment was designed to set up six different nitrogen application amount.The growth dynamics of tiller and the changes of spike production were investigated during the growing season.Result] Applied with 120 kg/hm2 nitrogen,Guiliangyou 2 had good community structure and high yield,while its community structure was the worst and yield was the lowest when applied with 300 kg/hm2.Conclusion] The study provided references for the appropriate nitrogen application amount and the high yield of Guiliangyou 2. |
