Clearing dead branches, fallen leaves and weeds in time to remove the deciduous, rotten fruit and weeds of the orchard, and bury it deeply or burn it, which can eliminate a large number of wintering pests and pathogens and reduce the pests and diseases of the leap year.
The ploughing and turning of the soil can turn the pests and germs of the winter larvae of P. sylvestris and P. sylvestris to the surface and freeze to death, dry or be eaten by natural enemies, so that the pests turned to deep layers cannot be feathered and unearthed. Suffocating, can improve the soil, enhance permeability, increase ground temperature, and is conducive to root growth. Tied the grass, scraped the bark, and painted the white 1. Use the pests of the small heartworm, the leaf miner, and the leaf-moth moth to choose the wintering place. Before wintering, tie the grass to the main trunk and the big branch to trap the mature larvae. Overwinter, then focus on elimination. 2. Pests, heartworms, pears, star caterpillars, moths and other pests and bacteria in the rough skin, skin, cracks of the fruit trees lurking winter, scraping bark in winter and then burned intensively, have a good control effect on a variety of pests and diseases. Be careful not to hurt the phloem when you are scratching. Manually remove the mites from the branches to achieve a fine and even. 3. Apply whitening agent on the trunk to effectively prevent freezing damage and kill the pests that overwinter on the trunk. It is better to coat the trunk twice, the first time in the early spring before the fruit trees are deciduous until the soil is frozen. For large trees with more cracked skin and more skinned skin, scrape the old skin, wrinkle the skin before applying white, and then apply white. Whitening agent formula: 10 parts of quicklime, 1 part of sulfur powder, 0.5 part of salt, 40 parts of water.
The winter shears are trimmed in the early winter, the canopy structure is adjusted, the dry branches and the diseased branches are removed, the long branches and the development branches are controlled, and the ventilation and light transmission conditions of the trees are improved. If the fruit tree is closed, you can take the "open skylight" approach. The pruning standard is to maintain the good ventilation and light transmission of the canopy. The cutting edge should be smooth, and the wound with a diameter of 1 cm or more should be immediately coated with a protective agent (the ratio of quicklime, stone sulphur residue, salt to water is 5:0.5:0.2:20). At the same time, the cut branches should be removed from the park in time and burned intensively.
