摘　　要：以超级稻盐丰47为材料,采用小区对比试验方法,进行机插氮肥运筹技术研究,确定盐丰47在机插条件下,基肥、蘖肥与穗肥的施用量一般为氮肥计划施用总量的15%、55%和30%左右。蘖肥适于插后的2、3叶龄期分期施入。最终可以获得10.26 t/hm2以上的产量。The nitrogen application of mechanized transplanting were researched by plot comparative test and used Yanfeng47 as experiment material, through the test it confirmed that under the condition of mechanized transplanting, the applied dosage of base fertilizer, tiller fertilizer and panicle fertilizer should be 15%, 55% and 30% from total nitrogen, the tiller fertilizer were suitable for using at the stage of two leaves and three leaves, and the yield could exceed 10.26 t/hm^2.
