    Results of field experiment showed that on the alluvial soils of Jilin Province, potash fertilizer applications could have a obvious yield-increasing effect on rice, and the optimum potash fertilizer rate was K2075 kg/ha, whose relative yield-increasing value was 7.34%, and the fertilizer utilization rate reached 53.6%, 1 000-grains weights and grain number per spike was the highest.
