摘    要:[目的]研究氮、磷、钾肥不同施用量对魔芋软腐病发生的影响。[方法]运用灰色关联度分析方法,对氮、磷、钾肥施用量与魔芋软腐病的发生进行综合评价。[结果]试验结果表明,过多施用氮肥易诱发魔芋软腐病,施用钾肥对控制软腐病有很好效果。[结论]在魔芋种植中应合理控制氮肥施用量,适当增施磷、钾肥,可起到减少魔芋软腐病发生的作用。

关 键 词:灰色关联度分析  魔芋      钾化肥  软腐病

Abstract:[Objective] The effects of different application amounts of nitrogen, phos-phate and potassium fertilizers on soft rot of konjac were investigated in this study. [Method] The grey correlation analysis was adopted to evaluate the correlation be-tween the application amount of nitrogen, phosphate and potassium fertilizers and the occurrence of soft rot of konjac. [Result] The excessive application of nitrogen fertilizer would induce the occurrence of soft rot of konjac, but the application of potassium fertilizer had a good control effect on soft rot. [Conclusion] The applica-tion amount of nitrogen fertilizer should be control ed reasonably in the planting of konjac, but the application amount of phosphate and potassium fertilizer could be in-creased to some extent, reducing the occurrence of soft rot of konjac.
Keywords:Grey correlation analysis  Konjac  Nitrogen fertilizer  Phosphate fertilizer  Potassium fertilizer  Soft rot
