Protect the blade
After the fruit is harvested, the fungicide and insecticide are sprayed in time to protect the leaves from harm. The larger the leaf area for photosynthesis of fruit trees, the more nutrients accumulated by photosynthesis, the more full the flower buds are formed and the more complete the branches.
Spraying foliar fertilizer
After harvesting the fruit, before the leaves, spray 0.3%~0.5% potassium dihydrogen phosphate solution every half month, or spray 0.3%~0.5% urea plus 0.3% potassium dihydrogen phosphate mixed solution to meet the nutrient growth of the fruit trees. Demand, increase the nutrient storage of the tree, prevent premature aging of the leaves. Foliar topdressing can extend the functional phase of the leaves, allowing them to make more nutrients stored in the fruit trees for root growth and germination and flowering next year. The blade can be protected simultaneously with a spray bactericide and an insecticide.
Early application of base fertilizer
After harvesting the fruit, it is necessary to apply the base fertilizer in time. This time, the fertilizer is the base fertilizer of the second year. The type should be based on organic fertilizer. Add appropriate amount of phosphorus and potassium fertilizer. Add appropriate amount of nitrogen fertilizer to the tree with excessive fruit hanging this year to restore the tree potential. The type of organic fertilizer is preferably sheep fat, cake fertilizer, green manure, etc. Phosphate fertilizer is powdered superphosphate, and potassium fertilizer is better. The method of applying the base fertilizer should be applied in a proper manner, and the depth of the fertilization ditch should be 30-40 cm. The amount of fertilizer applied is 2 kg of fertilizer per 1 kg of fruit per plant.
Orchard deep
Deep-turning can loosen grass, improve soil physical and chemical properties, improve soil aeration and water permeability, promote soil ripening, facilitate root growth and tree growth and development, and also pull out some insects and eggs that overwinter in the soil. freeze to death. In order to prevent deep roots from being damaged, the surrounding of the tree tray should be shallowly ploughed.
Orchard cleaning
Weeds, dead branches, fallen leaves, and pests and diseases are the wintering places where germs and pests gather. After the fruit trees are deciduous, the orchard should be thoroughly cleaned, and the weeds, dead branches, fallen leaves and pests and fruits should be deeply buried or burned to reduce the number of pests and diseases in the coming year.
Trunk painted white
Protect the trunk from frost damage and sun burns and kill pests and diseases. Whitening agent formula: 11 parts of quicklime, 2 parts of stone sulphur mixture, 1.5 parts of salt, 2 parts of fine clay, 40 parts of water, first remove the residue with water and remove the residue, then add water, salt, stone sulphur mixture and stir well. Finally, add fine clay and mix well, then use. Use a brush to evenly spread the paint on the trunk and large side branches.
