避雨栽培对魔芋软腐病发生及产量的影响

Effects of Rain Shelter Cultivation on the Occurrence of Soft Rot and Yield of Konjac

通过采用避雨栽培、药剂防治措施,研究其对魔芋软腐病的发病率、病情指数、防治效果及魔芋产量等方面的影响。结果表明,避雨栽培可有效降低土壤含水量,降低魔芋软腐病的发病率及病情指数,其防治效果明显高于药剂防治,同时提高了魔芋产量。

Measures including rain shelter cultivation and chemical control cultivation were used to study their effects on konjac soft rot disease incidence, disease index, control effect and yield. The results showed that rain shelter cultivation can effec-tively reduce the water content of soil, reduce the disease rate and disease index of soft rot of konjac. The control effect of rain shelter cultivation was significantly higher than that of chemical control; meanwhile, it also improved the yield of konjac.
