The latest course of management techniques and methods after fruit harvest of oranges

After the orange is picked, the nutrition of the tree is consumed and the tree is weak, so it is necessary to do a good job of management, otherwise it is not conducive to the overwintering of fruit trees and will affect the flower bud differentiation and yield of the following year. So how to manage it after the oranges are picked? Let's get to know it with the editor.

1. Inter-park transformation

The transformation should mainly do a good job in four aspects of light: first, we should carry out thinning reasonably for those orchards that are too densely planted, so as to facilitate ventilation and light, so as not to prevent the hanging fruit from moving out; second, the trees in the orchard should be ploughed and re-fertilized in time, so as to restore the tree potential and survive the winter safely as soon as possible, so as to facilitate the growth of the following year. The third is to gradually replace the old, weak, sick and disabled planting with low utilization rate, which has not affected the yield, and transplant the big trees with soil in time to ensure the basic number of trees; fourth, to expand holes and fertilize in batches to facilitate the growth and development of the root system.

2. Rational fertilization

Focus on fertilization after fruit harvest, fruit growth and ripening need a lot of nutrients, general fruit harvest results in little nutrition left, so timely fertilization to supplement nutrition, so that it can survive the winter smoothly. Because of the problems of tree potential and fruit yield, the tree potential varies after fruit harvest, so we should be reasonable in fertilization, less for prosperous trees, and skillful for weak trees, so as to maintain the balance of vegetative growth and reproductive growth of fruit trees as far as possible.

3. Proper pruning

Pruning is a meticulous light, which includes the management and correction of the tree shape of fruit trees, the pruning of weak diseased branches, and the reasonable collocation of fruiting branches and vegetative branches. Pruning in winter should follow: first, scissors, diseases and insect pests, weak branches, and cross branches; second, timely removal of immature late autumn shoots and diseased leaves, so as to avoid latent diseases and insect pests, and damage in the following year; third, it is necessary to reasonably match vegetative branches and fruit-bearing branches, usually 3:2 is better.

4. Pest control

After fruit picking, it is necessary to clear the garden, remove the branches and leaves of diseases and pests in time, and burn them together with the withered branches and leaves, diseased fruits and weeds on the ground, so as to remove the overwintering places of diseases and insect pests so as to avoid damage after the beginning of spring. At the same time, the whole garden sprayed stone-sulfur mixture, tree trunk whitening and other work to thoroughly control diseases and insect pests.

The above is the introduction of orange post-harvest management technology. I hope it can help you. If you want to know more about it, please pay attention to us.
