摘要
[目的]研究不同施氮水平对绿旱一号经济性状的影响,[方法]设置4个施氮水平分别对绿旱一号进行处理,通过田间试验考察不同处理条件下水稻的经济性状,并进行相关性分析.[结果]水稻的有效穗数、实粒数、瘪粒数、总粒数和总重与施氮量呈正相关,而结实率、千粒重与施氮量呈负相关,水稻的穗长与施氮量关系不明显.[结论]该研究为在水稻生产上进行合理施肥提供重要理论依据.
Abstract
[Objective] The aim was to study the effects of different nitrogen application rate on economic traits of Lvhan 1.[Method] Settingup four N use rate,the economic traits of Lvhan 1 under different conditions were investigated through field experiment,and correlation analy-sis was conducted.[Result] The results showed that effective spikes,filled grains,shriveled grains,total grains and total weight was positive-ly correlated with N amount,while filled-grain percentage and 1 000-grain weight was negatively correlated with N amount,the correlation be-tween spike length and N application rate was not significant.[Conclusion] The study provides an important theoretical basis for rational ferti-lization in rice production.
