摘　　要：通过麦后水直播稻15 kg/667 m2、18 kg/667 m2、21 kg/667 m2、24 kg/667 m2不同用氮量的对比试验研究,结果表明,总施氮量15 kg/667 m2的水稻生长量明显不足,施氮量21 kg/667 m2的水稻生长量略显偏多,施氮量24 kg/667 m2的水稻生长量明显偏多,而施氮量18 kg/667 m2处理不仅使水稻各生育期的生长清秀稳健,而且穗粒结构较为协调,同时还表现出较高的产量水平。从而初步明确麦后水直播稻施氮量以18 kg/667 m2为宜。The nitrogen content of 15 kg/667 m2,18 kg/667 m2,21 kg/667 m2,24 kg/667 m2 were tested on rice,the results indicated that increment was deficiency by content of 15 kg/667 m2,the increment of 21 kg/667 m2 has a little more than normal,the increment of 24 kg/667 m2 were better.The rice grew strong and heathy under the content of 18 kg/667 m2,at the same time the spike-grain structure was fine and the yield was high,so it made clear the content of 18 kg/667 m2 was the best.
