Abstract：In order to study the effects of bio-organic fertilizer on continuous cropping cucumber growth and rhizosphere microenvironment,the bio-organic fertilizer was fermented,pot experiment was designed.Blank control (CK),application of organic fertilizer(OF) and application of bio-organic fertilizer(BOF) were set to compare the differences of the cucumber growth and rhizosphere microenvironment.The results showed that the number of rhizosphere bacterial (12.36×107 cfu· g-1) and actinomycete (5.27×106 cfu· g-1) community were increased,while the number of the fungal (1.23×105 cru· g-1) was decreased;the pH,available P and available K were increased significantly,the three indicators increased 6％-11％,24％-125％,15％-29％ respectively.The activities of SOD and POD were also increased significantly,the two indicators increased 1 8％-42％,47％-1 13％ respectively.The rhizosphere community was changed,the physical and chemical properties of soil were improved,the antioxidant activity of protective enzyme was higher,the plants were stronger after using BOF.
