Three-dimensional prevention and treatment method of bacterial canker of kiwifruits

The invention provides a three-dimensional prevention and treatment method of bacterial canker of kiwifruits. The method comprises the steps that stem coating is conducted on plants in winter, pesticide and bactericide killing is conducted in time, and soil is improved and sterilized. In the stem coating stage, stem coating fertilizer is used, and the stem coating fertilizer, by mass, comprises 10% of plant oil processed through plasma treatment and 90% of polymer powder; in the real-time pesticide and bactericide killing stage, 50% of 600-800-fold tuzet wetting powder, 10% of 3500-4000-fold imidacloprid, 20% of 600-800-fold buprofezin, 10% of 1000-fold chlorfenapyr suspension liquid, 45% of 800-1000-fold ambam, 2.5% of 1000-fold efficient cyhalothrinmissible oil and water soluble fertilizer are adopted, and the water soluble fertilizer is plant oil processed through plasma treatment; in the soil modification stage, root fertilizer is adopted, and the root fertilizer, by mass, is composed of 1% of plant oil processed through plasma treatment, 90% of polymer powder and 9% of water. The three-dimensional prevention and treatment method has a remarkable bacterial canker prevention effect, and effectively prevents secondary damage and pathogen infection.
