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.
