Abstract A pot experiment was performed to study the effects of 4 microbial fertilizers（Lianchawang，Trichoderma，Jinbaobei and Hugenbao）on continuous cropping cucumber（Cucumis sativus L.）growth and soil physiochemical properties．Results showed that 4 microbial fertilizers significantly promoted the continuous cropping cucumber growth，among which Hugenbao microbial fertilizer had the best effects on vine length，leaf number，leaf dry weight，total plant dry weight and leaf area index of continuous cropping cucumber among the 4 microbial fertilizers，by increasing 54.8%，40.0%，96.0%，94.9% and 73.2%，respectively compared with the control，the difference reached significant level．Microbial fertilizers significantly increased chlorophyll and carotenoid content in cucumber leaves except for Jinbaobei．Lianchawang microbial fertilizer had the best effects on chlorophyll and carotenoid content in cucumber leaves，the increased range was 34.0% and 28.0%，respectively compared with the control．Trichoderma microbial fertilizer treatment could significantly decrease bulk weight and increase porosity of cucumber cropping soil．In addition，the 4 microbial fertilizers could significantly improve the chemical properties of cucumber cropping soil．Trichoderma microbial fertilizer treatment could increase soil pH，organic matter，and available nitrogen，phosphorus and potassium content by 4.3%，14.3%，21.5%，14.1% and 14.8%，respectively compared with the control，the difference reached significant level．In general，the order of comprehensive effect of 4 microbial fertilizers on cucumber continuous cropping obstacle was Trichoderma＞Hugenbao＞Lianchawang＞Jinbaobei.
