| 摘 要： | 为适应再生稻头季低桩机割条件下再生季分蘖生育特性的变化，设置再生季不同氮肥施用量和施用方法。通过观察分析再生季分蘖消长、产量及其构成，研究了再生季氮肥施用技术。结果表明，再生季经济施氮量为180 kg/hm2，采用早施促蘖肥，中期分次施用穗肥和粒肥的方法，可以有效促进有效分蘖的萌发及其穗粒发育，显著提高产量。

| Abstract: | In order to adapt to the change of growth characteristics of ratoon tiller with the main rice harvested by machine in low cutting, the nitrogen application rates and dates were set. And the nitrogen application technique in ratoon season was studied by observing and analyzing tillers, yield and its component. The results showed that, the economic nitrogen fertilizer application amounts was 180 kg/hm2 in ratoon season. The method of early promoting fertilization and fractionated application panicle fertilizer and grain fertilizer in middle may effectively promote the germination of effective tillering and its development of ear and grain, significantly increased yield. |
