摘　　要：对种芋不同含水量与魔芋软腐病的发病关系进行研究,结果表明:随着种芋失水量的增加,魔芋软腐病的发病期逐渐延迟,而软腐病的发生呈先减少后增加的趋势,其中当种芋失水量为15%时,发病率最低,仅为10.30%,而失水量为5%时,发病率最高,为25.30%。The relationship between different water content and the incidence of soft rot in Amorphophallus Konjac was studied.The results showed that：with increasing of the loss of water the occurrent stage of soft rot of Amorphophallus Konjac gradually delayed,the incidence of soft rot showed the trend of decreasing firstly and then increasing,during which when the loss of water of seed tuber was 15%,the incidence rate was the lowest,only 10.30%,while water loss was 5%,the incidence was the highest,25.30%.
