摘　　要：通过调查八五八农场地区主要稻田钾肥利用和水稻的需肥特性,研究钾肥不同比例(基肥与穗肥)对水稻产量和钾肥利用率的影响,结果表明:当基肥与穗肥比例为7:3时,钾肥回收利用率最高为34.3%,水稻产量623 kg/667 m2,增产7.3%。The effect of potassium application （base fertilizer and panicle fertilizer） on rice yield and potassium recovery efficiency were researched by investigated potassium recovery efficiency and characteristics of fertilizers required in 858 Farm, the result indicated that recycling rate of potassium was highest by 34.3% and yield of rice was 623 kg/667 mE by increasing 7.3% under the ratio of base fertilizer and panicle fertilizer was 7：3.
