摘要
[目的]研究不同氮肥施用量对超级稻桂两优2号生理特性和生长发育特点的影响。[方法]采取随机区组试验设计,开展6个相同密度不同氮肥施用量的研究,调查生长期间茎蘖穗的生长动态以及产量变化。[结果]120 kg/hm2氮肥处理超级稻桂两2号群体结构好,产量最高;300 kg/hm2氮肥处理群体结构差,产量最低。[结论]通过不同氮肥施用量的研究,为超级稻桂两2号及同类超级稻提供适宜氮肥施用量的参考。
[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.
