  • Tobacco bacterial wilt is the most difficult rhizome disease to prevent and control, and the costliest in production. In order to integrate a sustainable prevention and control technology system, aiming at the practical problems of slow growth at early seedling stage of tobacco, and serious harm of tobacco bacterial wilt in Tongzi County, Zunyi City, and based on the three years of practice in the region, this study integrates the prevention and control technology system of soil acid regulation, rhizosphere micro-ecological regulation, nutrient balance and resistance improvement technology, and evaluates the effect of integrated technology on tobacco bacterial wilt control, agronomic traits and economic traits of tobacco. The results showed that the physical and chemical properties of soil in the treatment area were improved. The treatment had a certain effect on the growth of tobacco. The whole growth period was significantly increased by 7 days. The promoting effect on growth at clumping stage and topping stage were the most significant, among which the plant height, stem circumference, leaf number, maximum leaf length, maximum leaf width and leaf area were significantly increased by 14.33%, 42.88%, 34.28%, 17.60%, 19.30% and 40.27%, respectively, compared with those in the non-treated area. In addition, the treatment could delay the occurrence of tobacco bacterial wilt to a certain extent, and the disease index and incidence rate in the treatment area were significantly lower than in the control area, and the relative control efficiency in the early stage was as high as 94.87%. The control efficiency of the outbreak period was as high as 78.91%, and the control efficiency of the stable period was still 71.39%. In terms of economic traits, compared with the control area, the income of the treatment area increased by 489.52 yuan/667 m2, and the average price of tobacco leaves increased by 1.12 yuan/kg. The demonstration results of this study can provide a reference for the research and development of green prevention and control technology for tobacco bacterial wilt.
