CitrusAfter harvesting, the tree is weak because the fruit takes away a lot of nutrients, so post-harvest management is required. First of all, we should pay attention to leaf preservation, especially the leaf-preserving large-fruited typeCitrusSuch as:Navel orange, Xinhui mandarin orange and sand sugar orange, etc., because of the large fruit typeCitrusThe post-harvest defoliation can seriously affect the yearFlower bud differentiation, the output of the coming year. In addition, fruit picking and pruning operations can cause wounds on the tree's body, which can be easily infested by pathogens. It is recommended to replenish the nutrients needed by the tree, improve the quality of the leaves, and quickly restore the tree's strengthFoliar fertilizerMake additions. In addition, it is also important to remove dead branches and leaves, and prune properly to reduce the breeding of pests and diseases. ForNavel orangeand other large fruit typesCitrusTrees, supplementing with magnesium, zinc, iron, boron and other trace elements are essential for leaf preservation. Magnesium deficiency can lead to yellowing of old leaves and severe defoliation, which can exacerbate the weakening of the tree. Therefore, when spraying, add micro-supplement Bili andDile water-soluble fertilizerSatisfiedCitrusPhotosynthetically related elements required by trees to prevent the problem of nutrient deficiency of yellow leaves and defoliation.
After harvesting, we should not only protect the leaves, but also pay attention to promoting flowers. Especially now exactly isFlower bud differentiationAdequate zinc and boron supplementation is important for the robust development of flower buds. CitrusofFlower bud differentiationIt needs to consume a lot of nutrients, and the post-harvest fruit takes away a lot of nutrients, if it is not supplemented in time with reproductive elements such as boron and zinc, it may lead to fewer flowers and weak flowers in the next year. It is recommended to spray micro-floral power and dilabor on the foliar surface after fruit picking, and carry out multiple sprays with an interval of 10-15 days to promoteFlower bud differentiationto produce more and more robust flower buds in the coming year.
Timely and reasonable application of winter fertilizer after harvest forCitrusThe restoration of the tree and the good yield of the coming year are very important. Winter isCitrustree'sFlower bud differentiationcritical period, so increasing the application of winter fertilizer is conducive to promotingFlower bud differentiationto lay a good foundation for a bumper harvest in the coming year. The application of winter fertilizer should pay attention to the useOrganic fertilizer, especially rottenOrganic fertilizerThe dosage should be sufficient. In addition, it is recommended to add micro-supplements to each treeDouble-force micro-supplementM45 granules, withOrganic fertilizerCompound fertilizerBury together. In this way, calcium, magnesium and nutrients such as zinc and boron can be supplemented at the same time to improve the robustness and promotion of the treeFlower bud differentiation。Finally, it is necessary to do a good job of plastic pruning, remove diseased branches, diseased leaves, moss and rotten fruits, etc., and take them out of the garden for destruction. In winter, the activity of pests and diseases is weak and it is easy to control, so spraying after harvest and after clearing the garden to reduce the number of pests and diseases to prevent the outbreak of pests and diseases in the next year.
In summary,CitrusPost-harvest management is essential for maintaining tree health, promotingFlower bud differentiationand a good harvest in the coming year is very important. By preserving leaves, replenishing nutrients, promotingFlower bud differentiationand reasonable application of winter fertilizer and other measures can be madeCitrusThe tree quickly recovers its vigor, improving yield and quality. At the same time, it is also necessary to pay attention to pest control and remove pests and diseasesCitrusAn important part of tree health.
