水稻旱育丢秧不同基蘖氮肥与穗粒氮肥比例对产量的影响

摘要

Under the condition of the same total application rate of nitrogen fertilizer, the effects of different ratios of base and tillering nitrogen fertilizer to panicle nitrogen fertilizer on the yield of hybrid rice variety "Gangyou 827", whose seedlings were cultivated in dry bed and transplanted by throwing, were studied. The results were gained as follows; when the ratio of base and tillering nitrogen fertilizer to panicle nitrogen fertilizer was 5:5, the yield per unit area of rice was the highest, and its comprehensive economic traits and the characters of the upper leaves were the best.%在同一施氮水平条件下,研究了水稻旱育丢秧不同基蘖氮肥与穗粒氮肥比例对杂交水稻冈优827产量的影响.试验结果表明:当基蘖氮肥与穗粒氮肥比例为5:5时,水稻的单产最高,综合经济性状和上部叶片的性状最优.
