Abstract:: The effect of different biological agents on the number of soil microorganisms，morbidity and yield of cucumber were studied using the method of dilution plate in greenhouse.The results showed that rooting agent could greatly increased the number of bacterium and actinomyces，increased by 772.11% and 412.85%,respectively.While fungus was increased by 34.17%.In addition，rooting agent and trichoderma compound agents T32 could decreased the morbidity of cucumber wilt disease，and yields were increased by 12.91% and 11.74% respectively.The conclusion was drawn that two kinds of biological agents could increased the number of soil microorganisms，decreased the morbidity of cucumber wilt disease and increase the yield of cucumber.
