Abstract A matrix cultivation was conducted to study the effects of 7 different species and concentrations of microbiological preparation on biomass，chlorophyll content and net photosynthetic rate of‘Jinyan No.4’cucumber（Cucumis sativus L．）．Biomass with remarkable growth promoting effect was screened out and their resistance to cucumber Fusarium wilt was tested．The result indicated that treatments with Ba（ bio-organic fertilizer） and Y（Chuang Bo microbial agents） performed better，and the best processing concentration for Chuang Bo is adding 10 mL diluted 600 times，and for Ba is adding 30 g per nursery substrate of one plug（4 L）．The plant resistance with Chuang Bo and Ba is higher than that of the control．The relative anti-effect is 14.5% and 27.4%，respectively．Under the condition of protected cultivation，for promoting cucumber growth and resistance to Fusarium wilt，we would suggest to use bio-organic fertilizer and add 30 g Bio per nursery substrate of one plug（4 L）
