通过研究不同氮、磷、钾肥施用量对魔芋软腐病发生的影响，结果表明，随着氮肥施用量的不断增加，魔芋软腐病的发病率逐渐增高，氮肥施用量与魔芋软腐病的发病率呈显著正相关；然而，随着磷肥、钾肥施用量的不断增加，魔芋软腐病的发病率随之降低，磷、钾肥施用量与魔芋软腐病的发病率呈显著负相关，其中，施用钾肥后的防病效果尤为明显。

This paper studied the effects of different application amounts of N, P and K fertilizers on soft rot disease of konjac. The results showed that the disease incidence of konjac soft rot increased with the increasing of nitrogen fertilizer application amount, and there was a significantly positive correlation between the application amount of nitrogen fertilizer and the disease incidence of konjac soft rot. However, with increasing of phosphorus or potassium fertilizer application amount, konjac soft rot disease incidence decreased, and there was a significantly negative correlation between the application amount of phosphorus or potassium fertilizer and konjac soft rot disease incidence, moreover, the effect of disease prevention was especially obvious after applying potassium fertilizer.
