摘　　要：田间试验研究了不同氮、磷、钾水平对水稻叶鞘腐败病病株率和病情指数的影响。结果表明,水稻叶鞘腐败病的病株率与N、P、K关系分别为:随氮肥施入量的增加,呈先上升再下降的趋势;随磷肥施入量的增加,呈下降趋势;随钾肥施入量的增加,呈先上升再下降的趋势。方差分析结果表明,病株率方面:N0与N3处理间显著,K0与K3处理间显著,其他处理间不显著;病指方面:K0与K3处理间显著,其他处理间不显著。The effect of different fertilizer on disease incidence and disease index of rice sheath rot disease were researched under different level of Nitrogen, Phosphorus and Potassium. The result indicated that rice sheath rot disease were increased at first and then decline with increasing Nitrogen; Rice sheath rot disease were decline with increasing Phosphorus; Rice slxeath rot disease were increased at first and then decline with increasing Potassium. The results of variance analysis show that treatment NO and N3, treatment K0 and K3 reached significant level on the aspect of disease incidence; Treatment K0 and K3 reached significant level on the aspect of disease index, other treatments were insignificant.
