摘  要:
[目的]研究氮肥运筹对钵苗水稻群体质量的影响。[方法]以甬优2640为供试材料,研究不同氮肥运筹对水稻茎蘖动态、成穗率、产量及其构成因素的影响。[结果]当总氮量为390 kg/hm~2,且基肥、蘖肥和穗肥比例为3∶4∶3时,水稻产量最高,氮肥最大程度被利用。[结论]该研究为提高氮肥利用率、形成量化氮肥施用高效运筹技术提供理论依据。

摘  要:
[Objective]To research the effects of nitrogen application on the population quality of rice pot seedlings. [Method]With Yongyou2540 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/hm~2 and 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.
