The effects of temperature,pH value,carbon and nitrogen sources on mycelium growth, conidi-um production and conidium germination of Fusarium oxysporum f. Sp. Cucumerinum were studied. The results showed that for the mycelium growth, conidium production and conidium germination of F. Oxysporium, the fitting range of temperature was between 20℃ and 30℃ ,the optimum value being 25℃ ,and the fitting range of pH was 5 ~7 with the optimum value being 6. Sucrose was the best carbon source for the mycelial growth, conidium production and conidium germination of the fungus. Among the tested nitrogen sources, potassium nitrate and urea were the best for mycelium growth and conidium production, but organic nitrogen was of more benefit to conidium germination than inorganic nitrogen.%研究了温度、pH值、碳源、氮源对黄瓜枯萎病病原菌生长、产孢以及分生孢子萌发的影响,结果表明,该病菌适宜温度为20～30℃,最适温度25℃.病原菌最适宜pH值为6,稍偏酸性环境更适宜病菌生长、产孢和孢子萌发.不同营养试验表明,碳源中蔗糖最有利于病菌生长、产孢和孢子萌发；在氮源中,硝酸钾和尿素最适于病菌生长和产孢,而有机氮较无机氮更有利于孢子萌发.
