Abstract: Soil restoration for continuous cropping obstacles has become a serious problem in the world. In this study, micro ecological preparation and plant vaccine agent (avirulent Ralstonia solanacearum) were combined to restore soil and prevent bacterial wilt disease. At 7 years continuous cropping tomato greenhouses field, two doses of micro ecological preparation (60 t/hm2 and 30 t/hm2) combining with plant vaccine agent were designed, and the control did not contain any micro ecological preparation or plant vaccine. The effects of different treatments on the contents of soil nutrients, soil enzymes, biological characteristics of tomato plant and the control efficiency against bacterial wilt disease were compared. The results showed that the contents of organic matter, total nitrogen, total phosphatase and exchangeable calcium for two doses of micro ecological preparation treatments were significantly higher than control treatment, while the content of total potassium was significantly lower. Moreover, the activities of soil urease, catalase, sucrose and acid phosphatase for two doses of micro ecological preparation treatments were also significantly higher than control treatment, and they were higher for the dose of 30 t/hm2 than for the dose of 60 t/hm2. The single fruit weight at the dose of 30 t/hm2 was 113.82 g, significantly higher than that of 60 t/hm2 dose (104.07 g) and control treatment (104.99 g) (P<0.05). Furthermore, the control efficiency of 30 t/hm2 micro ecological preparation (reaching to 91.87%) was also higher than that of 60 t/hm2.
