分期将黄瓜枯萎病、霜霉病、炭疽病接种在同一株黄瓜幼苗上，鉴定黄瓜的多抗性。结果表明：复合接种法与单一接种法的结果呈显著正相关，证明了复合接种法的可行性。黄瓜枯萎病用胚根接种法，选用浓度为１０４个孢子ｍｌ或１０５个孢子ｍｌ；黄瓜霜霉病用子叶点滴法接种，选用浓度为１０４孢子个ｍｌ；黄瓜炭疽病用子叶点滴法接种，选用浓度为５００个孢子ｍｌ，较适合用于复合接种多抗性鉴定。
Stages of cucumber wilt, downy mildew, anthracnose inoculated on the same cucumber seedlings, identification of cucumber resistance. The results showed that there was a significant positive correlation between the compound inoculation method and single inoculation method, which proves the feasibility of compound inoculation method. Cucumber blight by radicle inoculation method, the selection of the concentration of 104 spores ml or 105 spores ml; Cucumber downy mildew by cotyledon inoculation, the selection of a concentration of 104 spores a ml; cucumber anthracnose with cotyledons drip method Inoculation, the selection of the concentration of 500 spores ml, more suitable for multiple inoculation identification.
