摘要
Abstract
[Objective]To research the effects of nitrogen application on the population quality of rice pot seedlings. [Method] With Yongyou 2540 as the test materials,we researched the effects of nitrogen application treatments on rice tiller dynamic,percentage of earbearing tiller, yield and yield component factors. [Result] When total nitrogen amount was 390 kg/hm2and base fertilizer:tillering fetilizer:earing fertilizer was 3:4:3,rice had the highest yield and nitrogen fertilizer was used to the full extent. [Conclusion] This research provided references for enhancing the nitrogen use efficiency,and forming the efficient operation technology of quantitative nitrogen fertilizer.关键词
