试验结果表明,适当增施氮肥能促进免耕抛秧水稻立苗,有利于加快分蘖速度,提早够苗,增加穗粒数,从而提高产量。增施氮肥对晚稻免耕抛秧生育期无明显影响。以每公顷施纯氮181.5~198.0 kg为宜。
The results showed that proper application of N fertilizer could promote the seedling raising of no-tillage and throwing rice seedlings, which was good for speeding up the tillering speed, raising the seedlings earlier and increasing the number of grains per spike, so as to increase the yield. No significant effect of nitrogen application on no - tillage and seedling throwing stage in late rice. Apply nitrogen per hectare 181.5 ~ 198.0 kg is appropriate.
