以空育131和垦鉴稻6号为材料，设置3种氮肥施用策略（基肥∶蘖肥∶调节肥∶穗肥∶粒肥=4∶2∶1∶2∶1、5∶3∶0∶2∶0、4∶3∶1∶2∶0），研究不同氮肥运筹方式对寒地水稻生长和产量的影响，并提出最佳的施肥策略。结果表明，3种氮肥施用策略中，以基肥∶蘖肥∶调节肥∶穗肥∶粒肥为4∶3∶1∶2∶0处理的产量最高，是寒地水稻高产栽培中较为合理的氮肥运筹模式。

Effects of fertilization strategies on yield and yield components were studied with Kongyu 131 and Kenjiandao 6 as material in Cold Area. Three nitrogen application strategies(the ratio of nitrogen applied before sowing, tillering stage, growth transition stage, jointing stage and booting stage were 4∶2∶1∶2∶1, 5∶3∶0∶2∶0, 4∶3∶1∶2∶0) were designed. The results indicated that the highest yield was at the ratio of 4∶3∶1∶2∶0 in the three nitrogen application strategy, and it was suitable for rice cultivation in cold area.
