摘要
探讨了不同施氮量对水稻盐丰47生育及产量的影响。结果表明,施氮量为16 kg/667 m2的C处理,前中后期生长稳健,营养生长生殖生长协调,总颖花数、每穗成粒数多,单产最高为580.5 kg/667 m2,比D、E、B、A处理分别增加0.4%、3.7%、3.9%、7.2%。
Effect of nitrogen application amount on growth, development and yield of Yanfeng-47 .were discussed and the result indicated that treatment C which the nitrogen amount was 16 kg/667 m2 can achieve stable vigor, harmonize vege- tative growth and reproductive growth, increase flowers and grains per panicle, the highest yield was 580.5 kg/667 m2 which increase 0.4%, 3.7%, 3.9%, 7.2% than treatment D, E, B, A.
