When cutting in winter, it is advisable to cut off diseased branches, weak branches and dead branches as much as possible to avoid breeding and spreading in spring. Then, it is to scrape off the rotten skin and diseased skin on the branches and give them proper disinfection and protection. Light path pruning is what people often say is convenient lighting and ventilation pruning. That is, the process of cutting off dense branches, parallel branches, cross branches and inner branches.

First, the winter cutting time

The winter cutting time of pepper is generally from early spring to germination. Among them, it is especially suitable for late autumn and early winter and late winter and early spring, that is, to avoid freezing and cold weather.

Second, the winter cutting method

Zanthoxylum bungeanum is a small deciduous tree. Its tree is not tall and its branches are messy, but its branches have strong germinating ability and many ears. When pruning in winter, it is beneficial to prune from the aspects of disease prevention and insect control, lighting and ventilation, plastic dwarfing and so on.

1. Disease prevention and pest control pruning

Zanthoxylum bungeanum has a special fragrance and pungent taste, and has strong disinfection, sterilization, disease prevention and insect prevention capabilities, and is generally not prone to pests and diseases.

However, it does not rule out the occurrence of pests and diseases caused by weather, human negligence or management errors. Such as common root rot, rust, cotton bug, etc.

Therefore, when cutting in winter, it is advisable to cut off diseased branches, weak branches and dead branches as much as possible to avoid breeding and spreading in spring. Then, it is to scrape off the rotten skin and diseased skin on the branches and give them proper disinfection and protection.

2. Light path trimming

Light path pruning is what people often say is convenient lighting and ventilation pruning. That is, the process of cutting off dense branches, parallel branches, cross branches and inner branches.

Its main purpose is to make the branches and leaves receive light evenly, so as to promote photosynthesis and enhance the tree potential. At the same time, the purpose of dredging the wind and driving away pests and diseases is achieved. When pruning, cut it off from the base of the branch and coat it with disinfectant and protective material.

Step 3: plastic trimming

Plastic pruning refers to the process of pruning, reducing and delaying the strong branches, long branches and new branches of Zanthoxylum bungeanum in order to adjust the tree structure, balance the tree potential and beautify the crown.

Zanthoxylum bungeanum is not tall because of its small trees, but its stems and branches are prickly. Therefore, when people prune, they usually prune or pull branches to shape by retaining 3-4 main branches, so that they grow in a gratifying way and cultivate branches.

This can not only achieve the purpose of lighting and ventilation, but also promote light efficiency, enhance tree potential, ensure fruit quality, and facilitate picking.

Dwarf pruning

Zanthoxylum bungeanum is a small deciduous tree or shrub, and its tree generally grows very tall. However, because of its strong germination ability, it often happens that the branches are too high because of untimely pruning, which brings great inconvenience to picking.

Therefore, when cutting in winter, it is advisable to use methods such as cutting short, reducing weight and pulling branches to dwarf the tree, so that it can grow into a dwarf tree that can not only ensure the fruit quality, but also promote high yield and facilitate picking.

Third, Qingyuan

Cleaning the pepper garden is a continuation of the winter pruning of pepper trees. It seems that it has nothing to do with pruning, but it is inextricably linked. It is an important event that must be carefully completed in the process of pruning.

1. Burning

Burning is one of the rudest, simplest and most effective ways to clean the garden.

After the pepper is trimmed, the next task is to burn the cut branches, scraped rotten skins, dead leaves, residual branches and weeds under the tree. Its purpose is to avoid the resurgence of pests and diseases.

Spray medicine

When the burning is over, the next step is the further garden cleaning work-spraying drugs. Because after pruning, there will inevitably be "fish escaping from the net" in the tree body and soil, waiting for an opportunity to make a comeback.

Therefore, it is also necessary to spray disinfectant and insect repellent after clearing the garden. When spraying, spray the tree body first, and then spray it to the tree foot and the surrounding environment.

whitewash

Painting is a kind of maintenance method for people to sterilize and repel insects and reflect heat preservation. After burning and spraying, lime slurry can be used to paint the trunk of pepper tree. When whitewashing, try to choose sunny weather.
