Four points of winter management of fruit trees
In winter, when fruit trees enter dormancy, growth stops or activities are weak. The main points of winter management are to do the following four tasks: 1, to be combined with pruning to remove litter and pests and tissues, concentrated burning. Second, trim Third, antifreeze 3, the tree disc soil, the fruit tree to the trunk as the center, the tree disc soil 10-20 centimeters, but after the spring temperature rise picked up after the main soil around the open to expose the neck. 5. In winter drought conditions, conditional orchards can be irrigated from mid-December to early January. Orchards are more or less infected with pests and diseases during successive years of production. In the early stage of winter, insecticide sterilization should be based on the principle of prevention, prevention and control, so that fruit trees will not be attacked by diseases and insect pests, and fruit trees will thrive. Spray sterilization, spraying the ratio of ferrous sulfate: quicklime: water = 3:3:100 can be. Spray fine spray, spray uniform, with the distribution with the spray. It is worth noting that rain can't be sprayed on the rainy days, and windy days can't be sprayed. Sooner or later, when there is dew, it can't be sprayed, and high-temperature weather can't be sprayed. Otherwise, it is easy to produce phytotoxicity or reduce the efficacy of fruit trees. It is best to spray at 8-10 AM and after 3 PM. In order to eliminate and eliminate the breeding and breeding sites for pests and diseases, the orchards must be thoroughly cleaned after the fruit trees have entered a dormant period. Clean up dead leaves and rotten leaves with pests and diseases in the garden, and burn or bury them deeply. Autumn fruit trees, whether purchased or exported, must be subject to physical quarantine by the relevant phytosanitary authority. All seedlings with pests and diseases shall be destroyed and qualified persons may conduct transactions and plant cultivation.

2. Till the soil. Plowing the orchard will not only help improve the physical and chemical properties of the soil, but also help kill pests and diseases that overwinter in the soil.
3. For fruit trees with older trees and pear cracks, such as grapes and pears, they can be peeled and shaved.
4. Evergreen fruit trees use Baume 1 degree lime sulfur or 45% crystal lime sulfur agent in 100 times in winter, Peach, pear, grape, plum and other deciduous fruit trees use Baume 3-5 degree lime sulfur or 45% crystal stone Sulfur mixture 30 to 50 times the whole garden spray, can greatly reduce the winter sickness pest base.
After one year of growth, fruit trees are liable to cause tree-like disorders. In order to form a good crown structure, prolong economic life, and achieve high quality and stable yield, it is best to prune deciduous fruit trees in the winter from late December to January. Generally young trees and tree branches are lightly sheared; aging trees and weak tree power are sheared; trees with moderate fruiting periods and moderate tree vigor are trimmed, and the growth and result adjustments in the following year are carried out.

2, the main coating white, with 1 part of quicklime, 6? 8 parts of water, add a small amount of salt dubbed whitening agent, the main coating of the white, coated with a small amount of sulfur in the agent is even better.
4. Evergreen trees can use 0.5% urea solution or 0.3-0.5% potassium dihydrogen phosphate for extra-root fertilizer at noon on sunny days in winter to increase the humidity of orchards and increase the anti-freezing ability.
