Management operation of Yughubao litchi after harvest

How to maintain jade purse litchi after harvest? How can we establish a good tree shape and how to apply fertilizer? Let's take a look at it together.

1. Do a good job of pruning, cultivate strong fruiting branches, and establish a good tree type.

two。 Pay attention to the management of fertilizer and water to restrain the germination of late shoots in autumn and winter.

3. Strengthen the prevention and control of diseases and insect pests, protect the integrity of new shoots and leaves to maintain tree potential, etc.

Three management operations after harvest. I would like to give a brief explanation on the key points of the above management work.

1. Do a good job of pruning

The purpose of pruning Yuhebao litchi is to control plant height, adjust tree type, improve photosynthetic efficiency of leaves, avoid overgrowth caused by overdense crown branches and shading each other, improve ventilation and light transmittance of plants, and reduce the occurrence of diseases and insect pests.

If pruning is carried out early after harvest, the new shoots will germinate earlier. In the period of low temperature in winter, because the growth period is longer and the branches are more mature, it is easier to restrain the sprouting of evening shoots, so the pruning work after harvest should be carried out as soon as possible.

The pruning amount of branches can be adjusted according to the strength of trees and the number of branches. For over-dense branches, pest branches, withered branches, cross branches and weak branches should be cut off, while over-long fruit branches can be cut short to reduce unnecessary nutrient consumption. If the branch is too upright or high near the center of the plant, it is easy to cause the crown to rise, which is not conducive to the management operation in the future, so the main branch in the center can be sawed off to dwarf the tree.

two。 Pay attention to the management of fertilizer and water

After the harvest of jade purse fruit, in order to restore the tree potential and promote the rapid germination of new shoots, organic fertilizer can be applied as ceremonial fertilizer for the fruiting branches of the following year. After pruning, in order to promote the third shoot to mature from October to November and effectively inhibit the germination of the shoot, with the increase of the number of shoots, the application of nitrogen fertilizer should be reduced and the application of phosphorus and potassium fertilizer should be increased, so as not to stimulate the winter shoot germination and affect the flower bud differentiation.

Yuhebao litchi needs wet soil environment during shoot growth in summer to promote branch and leaf growth, while dry soil environment is needed in winter flower bud differentiation period to inhibit new shoot growth and promote flower bud formation. If the soil moisture is too high, will affect flower bud differentiation. Therefore, during the period of shoot growth after pruning, irrigation should be given properly, and during the period of flower bud differentiation in autumn and winter, irrigation should be reduced until after flowering.

3. Strengthen the control of diseases and insect pests

Since most of the inflorescences of Yuhebao litchi are drawn from the top or leaf axils of the mature branches of the year before last, the integrity of the leaves of the new shoots should be protected during the period of shoot germination in summer, and attention should be paid to the prevention and control of litchi diseases and insect pests at any time to avoid damage to new shoots, tender leaves or tree trunks, affecting plant nutrient accumulation, resulting in weak tree potential, poor flowering and fruiting. Common diseases and insect pests include litchi moth, rust tick, leaf curler, glue worm, longicorn beetle and so on.

With so much information, you should know what to do.
