Abstract:
The number of culturable microorganisms were measured by traditional method.Soil enzyme activity，plant phenotypic traits and incidence number were determined by routine analysis methods,to explore the synergism of biocontrol agents bacteria D，actinomycetes 317 and fungi compound to cucumber Fusarium wilt.The results showed that three agents compound was superior to single agent and two agents compound，its synergism was the best.Three agents compound was compared to control；number of bacteria，actinomycetes and fungi could raise 50.57%，110.98% and 13.48%；microflora was becoming fungi type to bacteria type；activity of phosphatase，invertase，catalase and urease could raise 244.90%，7.17%，2.90% and 31.01%；plant height，stem diameter，leaf number and dry matter weight could raise 33.92%，35.48%，34.43% and 79.13%；control effect could raise 52%.Compared to control，three agents compound had clear synergism in number microorganism，microflora，plant phenotypic traits and control effect.The synergism to phosphatase，invertase and urease was not clear，but to catalase was clear.Three agents compound would have great application potential in production.
