In spring, the fruit trees will sprout soon, and many fruit farmers have begun to scrape rough skin. There is no doubt that scraping bark and applying chemicals are routine measures to prevent rough skin disease, but every year, many tumors of fruit trees are scraped off, which is still a headache for fruit farmers.

Therefore, it is particularly important to adopt reasonable methods and choose good chemicals to prevent and control the rough skin of rings:

1, strengthen management and enhance tree potential.

Balance application of nitrogen, phosphorus and potassium, and increase application of organic fertilizer; Reasonable annual plastic pruning to minimize girdling; Reasonable fruit thinning, strict control of load, and enhancement of tree potential.

2. Lightly scrape the rough skin of wheel tread and the old warped skin

Scrape the bark gently, but not too hard. As the saying goes, "people want face, trees want skin", and trees can't live without skin.

From the perspective of modern science, bark is the place where fruit trees transport and store organic nutrients. Excessive peeling in early spring is equivalent to a large area wound on the tree, which is easy to dry and dehydrate, resulting in cracks, which not only loses a lot of nutrients, but also needs a lot of nutrients to heal. The result is that the nutrients used for germination and flowering are greatly reduced, which seriously affects the yield and quality of fruits.

Step 3 apply medicine

After many years of experiments, it has been proved that the application of 5 ~ 10 times of membrane force 56 suspension concentrated solution or 20 ~ 30 times of original clear solution can prevent and control ring rot well.
