Scrapping the bark saying goes: "To eat pears, scrape the bark." This is very reasonable. In the rough skin, cracks, and cracks of fruit trees, many pests such as Pyrosphaeridae, Hawthorn spider mites, Myzus persicae, Mythica spp., Myxidae, Pyriacidae, etc. are often lurking. Before the budding of the fruit trees in early spring, thoroughly remove the rough skin and cut kerfs on the stems (especially at the tree branches). Can eliminate a large number of wintering pests. The degree of scraping the skin to scrape off the light brown skin see green not white. When scraping the skin, it is necessary to put a plastic cloth under the tree to collect the scraped bark and crumbs, and to concentrate deeply or burn them. For fruit trees with rot and blight disease, apply Fumei arsenic or lime sulfur to prevent and cure after scraping. Shaving the trees in the early spring is not only an important measure to improve the soil and promote the production of fruit trees, but also an effective method to eliminate overwintering pests. Through deep plowing, pests (peach borer, peach pit, etc.) and pathogens that overwinter in the soil can be turned to the surface and frozen, dried or destroyed by natural enemies, and some of the dead branches, rolling leaves and Weeds in the weeds and pests (fly moths, aphids, red spiders, etc.) are buried underground and cannot suffocate due to their normal emergence. Before the overwintering larvae are unearthed, the overlying mulch film is glued into a piece according to the size of the crown projection, and a slit is cut from one side to the middle point. The shearing seam is pulled out from the trunk of the crown and the edge of the mulching film is buried underground. Hand over about 20 centimeters and tighten the cord with the trunk (the film can last until early September). Covering the mulching film has obvious effects on reducing the harmful effects of insects such as red spider, peach borer and other pests. Spraying deciduous fruit trees during dormancy, spraying 1 to 2 times diesel oil containing 4% to 5% diesel oil, and 5 Baume degrees of lime sulfur to harm various species of scale insects, red spiders, and apple rot. Pear tree scab, grape black spot disease, etc., have significant control effect.
