Fruit tree scraping rough notice

Scraping the rough skin of the fruit tree can effectively prevent the occurrence of rot disease and ring disease, and restore the weak tree to life. Practice has proved that early spring scraping is better than winter, especially in alpine regions, which must be scraped in early spring to prevent frost damage.

The rough skin should be mastered with the principle of “redness and no whiteness”, that is, it is better to scrape the red endothelium. The lack of red indicates that the shaving is shallow, and the white indicates that the shaving is deep, the former is poor, and the latter is weakening the tree. Tree species, different ages, different degrees of scraping, such as old trees, premature aging trees should be heavier and deeper, the first fruit trees should be shallower and lighter.

After scraping the skin, the affected area should be coated with methyl thiophanate or a 5 degree stone sulphur mixture or whitening agent to prevent the invasion of the bacteria, and the scraped rough old skin is burned or buried deeply.
