The removal of old cracks from fruit trees is an effective measure to eliminate pests and rejuvenate the tree. This is a good measure. Pests can be reduced by 70% to 80% over the winter, pathogens are reduced by more than 80%, and the use of drugs is reduced by 1 or 2 times in the growing season. Save money and increase efficiency. However, there are many problems in the scraping of bark by the fruit growers in production. The five-five and five-failure are not recommended for your reference.
First, should not be too late
Most people think that the sooner the scraping is done from leaf to flowering, the better. It is actually wrong, because it takes several months before the leaves fall to flowering. The early scraping of the skin is due to the exposure of young tissue, wind and sun, and loss of moisture. On the other hand, after scraping off the old skin, it is equivalent to people taking off a layer of clothes, and the ability to resist coldness is obviously reduced. Therefore, it is better to scrape the skin before the pests emerge before they sprout.
Second, should not be shallow
People need skins on their faces. A considerable number of fruit growers are too deep and heavy to shave, so that fresh and disease-free protection organizations are severely damaged and affect the normal growth of the trees. Therefore, it is appropriate to have just enough to scrape the body and knock off the skin. The trees are white and the trees are green and the disease-free body is not scratched.
Third, should not be thick
Do not scrape only the main skin, the main branch of the epidermis, for more than one year must observe carefully, do not miss a small tumor, because mung bean size tumors can produce hundreds of millions of colonies, the whole tree scraping Also check it up and down again and again to achieve complete and complete goals.
Fourth, should not be buried with
When scraping the skin, pay attention to the tree under the cover of plastic paper or chemical fertilizer bags, etc., and collect the epidermis disease at the same time, do not bring out the orchard edge or burn, because the bacteria brought to the garden can continue to spread with water flow, burning waste of nutrition, It is best to dig more than 30 centimeters deep in the orchard and bury the fallen leaves in the tree. After rot, it is a better nutrient.
Fifth, should not be old
After scraping the skin, you should not use Fumei arsenic coating or spray that has been effective, high residue, and highly pathogenic in the past. Use pollution-free biopesticides 5 times or even non-polluting chemically synthesized gum tree, biofilm, etc. The bactericidal protection of the brush spray, especially the gum tree, the biofilm is applied to the tree to form a film, the bacteria is not easy to invade and infect, and the moisture of the tree is not easy to dissipate.

Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
