The results showed that, at all the growth stages of tobacco, the quantity of microorganisms in the rhizosphere soil added with the soil conditioner was higher than control （CK）. The results of metagenome detection indicated that the diversity of microbial communities in soil added with the soil conditioner was also higher than the CK, and the rate of tobacco bacterial wilt and the disease index decreased by 27.6% and 34.6%, respectively, compared with the CK. In conclusion, the soil con- ditioner could reduce the soil-borne disease by improving micro-ecological environ- ment and diversity of microbial communities in rhizosphere soil to maintain the soil balance.展开更多
