摘　　要：对不同海拔不同魔芋专用肥施用量对魔芋产量和发病率的影响进行试验研究,结果表明,随着海拔升高,发病率降低,海拔700m以上区域较适宜魔芋生长。施用魔芋专用肥的各处理鲜芋产量和膨大系数均高于不施肥(CK),其中667m2施肥75kg为最佳施肥量,产量和膨大系数较高,发病率较低。播种种芋大小与出苗率呈正相关、与膨大系数呈负相关。The main disease of konjac is soft rot of Amorphopallus in Ankang. With the altitudes rise, the soft rot of Amorphopallus rate decline, konjac is suitable for growing at an altitude of above 700 m. The output and coefficient of expansion of konjac corm, which is fertilized with konjac special fertilizer are higher than no fertilized. The size of planting konjac corm is positively correlated with rate of seedling, and negatively correlated with coefficient of expansion. The best fertilization is 75 kg per 667 m2.
