Root irrigation can promote root development, strengthen plants and enhance their disease resistance. The orchard was sprayed with Kuifuling and organosilicon to sterilize and disinfect.

The apple tree needs to be inspected in early spring and early March and September in autumn. Scraping off the rough skin and old warped skin on the trunk side branches can not only check the rot and dry rot, but also scrape off the overwintering eggs in the warped skin to facilitate spray insecticidal. After the inspection, using anti-rot medicine to coat the rod, the warped skin will gradually warp up, which is conducive to the growth of the old skin and the new skin.

When diseased spots are found, scrape off the diseased spots on the branches until they are white (good), then use Kuifuling solution and silicone to evenly smear 3-5 times, each time at an interval of 3-5 days, the application range should be 2-3 cm beyond the scraping range. In the later stage, it is necessary to spray and brush the branches with Kuifuling and other agents. Use Liangguoan, Wofengsu and so on for foliar spray.
