摘　　要：【目的】研究生防放线菌与草木灰混合包衣黄瓜种子对黄瓜的生长效应,为黄瓜栽培与病害防治提供理论依据。【方法】设生防放线菌与草木灰1∶50、1∶25、1∶10及纯草木灰混合包衣黄瓜种子处理,探讨不同比例的生防放线菌对黄瓜种子出苗、黄瓜幼苗株高、根长及生理生化指标的影响。【结果】生防放线菌对黄瓜出苗有抑制作用,但适宜浓度的生防放线菌制剂能促进黄瓜幼苗株高和根的生长,提高叶片叶绿素含量和过氧化氢酶及硝酸还原酶活性。【结论】在黄瓜生产中,可以采用生防放线菌制剂∶草木灰=1∶25的菌粉包衣黄瓜种子,以提高黄瓜的产量和品质,提高黄瓜种植的经济效益。[Objective]The present experiment was conducted to study the effect of actinomyces bio-control on growth of cucumber to offer the reference on cultivation and disease control in cucumber plantations.[Method]Different mixed ratios of bio-control actinomyces and plant ash（1∶50,1∶25,1∶10）used for coating cucumber seeds were designed to investigate their effects on seed germination,plant height,root length and physiological and chemical characteristics of cucumber.[Result]Bio-control actinomyces had inhibitory effects on germination of cucumber,while suitable concentration of actinomycetes preparations promoted the growth of plant,improved the plant height and root length,and increased the chlorophyll content and activities of CAT and nitrate reductase in leaves.[Conclusion]The actinomycetes and plant ash in ratio of 1∶25 used to coat seeds was found most favorable to enhance the yield,quality and economic benefits.
