How to manage pear trees during the dormant period? A detailed explanation of the latest technical key points
Pears are a fruit that many people enjoy eating very much, and the planting area of pear trees in our country is also very large. In the growth throughout the year, pear trees are generally divided into the dormant period and the growth period. In winter, pear trees generally begin to enter dormancy, stopping most of the physiological activities of the tree body. So how should they be managed after pear trees enter the dormant period? Below, the editor will give everyone a brief introduction. Let's take a look together!
1. Winter pruning and shaping
After 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 high-quality, high-yielding tree structure. Therefore, when pear trees are in the dormant period, most of the nutrients in the tree body are in the branches and roots. If some useless branches are pruned off at this time, nutrients can be effectively saved. It is also very beneficial to the growth of the tree the following year. Winter pruning is mainly to adjust branches and buds, renew fruiting branch groups, and at the same time adjust the growth angle and direction of the main branches well, and control the growth amount and flower bud amount of pear trees well.
2. Scraping off tree bark
During the dormant period of pear trees, in addition to doing a good job of pruning, we should also pay attention to timely scraping off the old bark on the trunks. For the thick old peeling bark on some main trunks and main branches, we must not be soft-handed. This is because these barks basically hide many insect eggs and pathogens, and are their main overwintering sites. When the environment is suitable the following year, they will begin to become active and affect the growth of pear trees. If pear trees have disease spots such as rot disease and ring rot disease, they should also all be scraped off, and then the scraped disease spots should be concentrated and taken out of the orchard for burning treatment.
3. Orchard cleaning work
When carrying out winter pruning, we should pay attention to removing some old, weak, diseased and disabled branches and some diseased and mummified fruits. Then sweep the fallen leaves, fallen branches, fallen fruits and so on in the orchard, and then spray the trees comprehensively once with an eradication agent. After cleaning up the fallen branches, fallen leaves and fruits, they should be classified and handled well. If they are fallen leaves, then we can use them as raw material for compost. Residual branches and fallen fruits should be burned or deeply buried. Orchard cleaning work is a key measure to eliminate pests and pathogens, and is also the key to ensuring the normal growth of pear trees the following year.
4. Thinning flower buds
The flower buds of pear trees are very good for people and livestock; during winter pruning, for some trees in an on-year, flower thinning work should be carried out in advance. If there are too many flowering branches, then according to the branch-to-fruit ratio, the tops should be broken or shortened back to reduce the number of flower buds. If it is a tree in an off-year, then the main approach should be to keep all flowers seen, reducing the nutrient consumption of the tree body. For vegetative branches, short cutting should be carried out to avoid too many flower buds the following year. And if there are few flowers or no flowers, then some high-quality leaf buds should be retained to improve the quality of new shoots, enhance the photosynthetic capacity of the tree body, and prompt the tree vigor to recover as soon as possible.
The above is a brief introduction to how to manage pear trees during the dormant period. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
