How to manage the dormant period of pear trees

Pear is a kind of fruit that many people like to eat very much, and the planting area of pear trees in our country is also very large. The growth of pear trees in the whole year is generally divided into dormant period and growing period. Pear trees generally begin to dormancy in winter, stopping most of their physiological activities. So how to manage the pear tree after entering the dormant period? The following editor will give you a brief introduction, let's have a look!

1. Winter shearing and plastic surgery

After the pear trees enter the dormant period in winter, it is the most suitable time for winter pruning and shaping of pear trees. The main purpose of shaping is to cultivate a tree structure with high quality and high yield. Therefore, when the pear tree is dormant, most of the nutrients in the tree are in the branches and roots. Cutting off some useless branches at this time can effectively save nutrition. And it is also very beneficial to the growth of the tree in the following year. The main purpose of winter shearing is to adjust the branches and buds, renew the fruiting branches, adjust the growth angle and direction of the main branches, and control the growth and flower buds of pear trees.

2. Scrape off the bark

During the dormant period of the pear tree, we do a good job of pruning. We should also pay attention to scrape off the old skin on the trunk in time, and should not be soft on the thick old warped skin on some trunk branches. Because these barks are basically latent a lot of eggs and germs, is their main overwintering place. When the environment is suitable in the second year, activities will begin to affect the growth of pear trees. If pear trees have disease spots such as rot and ring disease, they should also be scraped off, and then the scraped disease spots should be taken out of the orchard to be burned.

3. the work of clearing the garden

When we carry out winter pruning, we should pay attention to the removal of some old, weak, sick and disabled branches and some diseased nuts. Then clean up the fallen leaves, branches and fruits in the orchard, and then fully spray the tree with a scavenging agent. After cleaning up the fallen branches and deciduous fruits, they should be classified. If the leaves are fallen, then we can turn them into composting materials. On the other hand, the remnant branches and fallen fruit should be burned or buried deeply. Garden cleaning is not only the key measure to eliminate insect pests and germs, but also the key to ensure the normal growth of pear trees in the second year.

4. Dredge flower buds

The flower buds of pear trees are very good for people and animals, and flower thinning should be carried out ahead of time for some big trees during winter cutting. If there are too many flower branches, then the top should be broken or retracted according to the branch-fruit ratio to reduce the number of flower buds. If it is a small tree, it is necessary to see the flowers stay mainly to reduce the nutrient consumption of the tree. Cut short the vegetative branches to avoid too many flower buds in the second year. If there are few flowers or five flowers, then it is necessary to retain some high-quality leaf buds, improve the quality of new shoots, enhance the photosynthetic capacity of the tree, and promote the tree potential to recover as soon as possible.

The above is a brief introduction to how to manage the dormant period of pear trees. That's all for today's introduction. This article is for reference only. I hope it can help you all.
