How to manage orange trees after fruit harvest? Latest technical method tutorial

After oranges are harvested, the tree's nutrients have been consumed and the tree vigor weakens, so management work must be done well; otherwise it is unfavorable for the fruit trees to overwinter and will also affect flower bud differentiation and yield the following year. So how should · management be done after oranges are harvested? Let's learn about it together with the editor.

1. Orchard renovation

Renovation mainly requires doing well in four aspects of light. First, for those orchards planted too densely, reasonable thinning should be carried out to facilitate ventilation and light penetration, so as to prevent fruiting from shifting outward; second, for trees in the orchard whose vigor has weakened due to excessive fruiting, timely deep plowing and heavy fertilization should be carried out so they can recover vigor as soon as possible and overwinter safely, facilitating growth the following year; third, old, weak, diseased and disabled plantings with low utilization rates should be gradually replaced to avoid affecting yield, and large trees that have already fruited should be timely transplanted with soil to fill the gaps, ensuring the basic number of plants; fourth, hole expansion and fertilization should be carried out in batches to facilitate root growth and development.

2. Reasonable fertilization

Fertilization after fruit harvest is the key point. Fruit growth and ripening require large amounts of nutrients, and generally after fruit harvest the fruit tree has very few nutrients left, so fertilization should be timely to supplement nutrients and allow it to overwinter smoothly. Because of differences in tree vigor and fruiting amount, tree vigor after fruit harvest varies, so fertilization should be reasonable: vigorous trees should be fertilized less, while weak trees should be fertilized skillfully; blind fertilization is also inadvisable, and efforts should be made to maintain the balance between vegetative growth and reproductive growth of the fruit trees.

3. Proper pruning

Pruning is a meticulous task involving light. It includes management and correction of the fruit tree's tree shape, removal of weak and diseased branches, and reasonable matching of fruiting branches and vegetative branches. Winter pruning should follow these principles: first, prune injured, pest-damaged, weak and crossing branches; second, timely remove late autumn shoots that have not matured and diseased leaves, so as to prevent pests and diseases from lurking and causing harm the following year; third, reasonably match vegetative branches and fruiting branches, generally 3:2 is best.

4. Pest and disease control

After fruit harvest, orchard cleaning work should be done well, timely removing diseased branches and leaves, and burning them together with dead branches, fallen leaves, diseased fruit and weeds on the ground, clearing overwintering sites of pest and disease sources, so as to prevent harm after spring begins. At the same time, spray the whole orchard with lime sulfur mixture and whitewash tree trunks, among other work, to thoroughly control pests and diseases.
