| 摘 要： | 连作障碍的土壤修复是世界性难题。本研究利用土壤微生态修复剂结合青枯病植物疫苗菌剂来改良土壤和预防青枯病发生。在连作7年的番茄地，设3种处理，处理1为添加量60 t/hm2的土壤微生态修复剂和植物疫苗100倍稀释液，处理2为添加量30 t/hm2的土壤微生态修复剂和植物疫苗100倍稀释液，CK为不添加土壤微生态修复剂和植物疫苗，研究不同处理对连作番茄土壤养分、土壤酶活性、植株生长特性及病害防效的影响。结果表明，土壤微生态修复剂2种不同添加量处理的番茄土壤有机质、全氮、全磷和交换性钙含量均显著高于对照，而全钾含量显著低于对照；两种不同添加量处理的番茄土壤过氧化氢酶、脲酶、蔗糖酶和酸性磷酸酶活性均显著高于对照，添加量为30 t/hm2处理的土壤各酶活性（酸性磷酸酶除外）大于添加量为60 t/hm2处理的土壤；添加30 t/hm2处理的单果重量（113.82 g）显著高于添加量60 t/hm2处理（104.07 g）和对照处理（104.99 g）（P<0.05），其对番茄青枯病防效达91.87%，大于添加量为60 t/hm2处理的防效（55.34%）。

| 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. |
