摘    要:目的]研究不同氮肥运筹对钵苗机插水稻性状及产量的影响。方法]以杂交籼稻Ⅱ优118和常规粳稻武运粳27为材料,研究不同基蘖肥和穗肥比例对水稻茎蘖动态、成穗率、产量及其构成因素的影响。结果]基蘖肥:穗肥为7∶3的氮肥运筹方式有利于提高穗数,增加产量;Ⅱ优118以基蘖肥178.5 kg/hm~2、总用氮量255 kg/hm~2的处理的产量最高;武运粳27以基蘖肥252.0 kg/hm~2、总用氮量360 kg/hm~2的处理的群体产量最高。结论]该研究为钵苗机插水稻的最佳氮肥运筹方式的推广提供理论基础。

关 键 词:氮肥运筹方式  Ⅱ优118  武运粳27  成穗率  产量

Abstract:Objective] To research the effects of nitrogen application regimes on the character and yield of machine transplanted rice seedling from pot.Method] With Indica hybrid rice Ⅱ you 118 and conventional Japonica rice Wuyunjing 27 as the research materials,we researched the effects of basic tiller fertilizer-earing fertilizer ratio on the rice tiller dynamics,ear forming rate,yield and yield component factors.Result]Nitrogen application regime of 7∶3 basic tiller fertilizer-earing fertilizer ratio was helpful to enhance the ear number,and increase the yield.Ⅱ you 118 had the highest yield at 178.5 kg/hm2 basic tiller fertilizer and 255 kg/hm2 total nitrogen amount;while Wuyunjing 27 had the highest yield at 252.0 kg/hm2 basic tiller fertilizer and 360 kg/hm2 total nitrogen amount.Conclusion] This research provides theoretical basis for the extension of the optimal nitrogen application regime for machine transplanted rice seedling from pot.
Keywords:Nitrogen application regime  Ⅱ you 118  Wuyunjing 27  Ear forming rate  Yield
