摘　　要：在沈阳市苏家屯区进行水稻土钾肥施用效果研究,结果表明:在速效钾含量丰富(120 mg/kg以上)的田块施用钾肥增产效果不明显,可以减少施用量;在速效钾含量偏低(80 mg/kg以下)的地块施用钾肥可以提高水稻产量,施用量以187.5 kg/hm2最为经济。Effect of K fertilizer in paddy soil was studied in Sujiatun District of Shenyang City.The results showed that effect of K fertilizer was not obvious in plots rich in potassium（ 120 mg/kg or more ） .Therefore ,the amount administered of K fertilizer could be reduced.It could increase rice yield when the potassium content was low （80 mg/kg or less ）, and fertilizer to 187.5 kg/hm2 most economical.
