摘　　要：[目的]探索仁用杏叶及中草药植物源提取液对黄瓜黑星病的抑制效果。[方法]选择仁用杏叶及中草药提取液,以黄瓜主栽品种津绿3号为材料,通过盆栽试验对黄瓜黑星病预防效果进行研究。[结果]中草药制剂(黄柏、金银花、丁香、荷叶提取液混配)、仁用杏叶提取液和黄柏叶提取液3种植物提取液对黑星病菌都有一定抑制作用,仁用杏叶提取液效果最显著,该处理对黄瓜黑星病菌的抑制效果达22.83%。黄瓜植株遭受黑星病原菌侵害后,施用仁用杏叶及中草药植物源提取液的黄瓜植株中抗氧化酶(POD和SOD)活性上升,黄瓜植株对黑星病菌抵抗能力增强。[Aims] The aim of the research was to explore the reasonable application of kernel apricot leaves and different Chinese herbmedicine on the control of Cladosporium cucumerJnum. [Methods] Effect of kernelapricot leaves and different Chinese herbmedicine （ZY, RXY, HB） on the performance of cucumber seedling infected by pathogen （C. cucumerinum） was studied in green house. [IRosults] The results showed that, the fungiof Cladosporium was inhibited by 3 kernel apricot leaves and different Chinese herbmedicine, especially for the RYX. About 22.83% pathogen was inhibited on the RXY treatment compared with the control, and about 12.69and 18.49% pathogen was inhibited by ZY and HB, separately. The defense system （POD and SOD） of cucumber was induced and strengthened by these kernel apricot leaves and different Chinese herbmedicine while the plantwas attacked by pathogen of C. cucumerinum.
