Pear trees are not neglected after harvesting
After picking the fruit, the pear trees will remove the fallen leaves, rotten fruit and weeds around the orchard in time, and concentrate on deep burial or burning. The "General Tree Protection" will be used to completely disinfect the clearing garden to prevent the spread of bacteria and pests in the trees and to become the source of pests and diseases in the second year. In the early spring of the next year, it will be sprayed again to eliminate the source of the disease and the source of insects, and reduce the occurrence of pests and diseases of pear trees. It is also possible to eliminate a large number of wintering germs and pests that are lurking in the rough skin, the skin and the trunk cracks of the pear trees by scraping the bark. Rot and pathogens, P. sylvestris and Star caterpillars, and Hawthorn red spiders mostly overwinter in the rough skin and cracks of fruit trees. In the winter or early spring, the old skin of the pear tree is scraped off with a spatula, and then the "callus antiseptic film" is used. "Smear the wound in time and close it. The old skin that has been scraped off should be burned or buried deeply.
After picking fruit, fungicides and insecticides can be used to control various pests and diseases of pear trees, protect the leaves, prevent early leaves, and affect the annual yield. When using the chemical control, it is necessary to add an appropriate amount of "new high-fat membrane" to improve the efficacy and the best control effect.
After picking the fruit, the pear garden should be ploughed, the soil can be loosened, the permeability can be enhanced, and the pests and diseases can be reduced. The depth of the tillage around the tree tray is about 10 cm, 20 to 25 cm outside the tree tray. After ploughing, timely irrigation according to the grievances. Through the deep turn of the orchard in autumn and winter, the pests that are hiding in the soil under the canopy to prepare for wintering can be turned out of the ground, allowing the birds to forage or freeze to death. At the same time, the deep turn can also bury the dead leaves of the diseased leaves on the ground and the pests hiding in the dry grass. In the following year, they can not be unearthed and suffocated. Pear trees are deciduous until the freezing of the trunk, which can prevent the fruit trees from burning and freezing, and can also eliminate the bacteria and pests that overwinter on the trunk.
