土壤中的病原菌是导致蔬菜作物发病的重要原因之一，尤其是上传病害，病菌往往可以在土壤中存活数年之久，防治非常困难。如茄子黄萎病菌可以厚垣孢子、拟菌核和菌丝体形式随病株残体在土壤中存活６～８年，瓜类枯萎病病菌在土壤中无寄主寄生的情况下仍能存活５－６年。由于菜 Pathogenic bacteria in soil is one of the important reasons leading to the occurrence of vegetable crops, especially the disease of uploading, the bacteria can often survive in the soil for several years and the prevention and treatment are very difficult. Such as eggplant Verticillium wilt chlamydospores, pseudomycoccus and mycelium form with the residual disease in soil survival of 6 to 8 years, Fusarium wilt pathogens in the soil without host parasites still survive 5 - 6 years.
