Pear tree pruning time and method in winter
Pear pruning in winter can regulate the relationship between vegetative growth and results, and achieve high and stable yields year after year.
First, pruning time
It is carried out from December to the next year when the pear tree germinates.
Second, the pruning method
First of all, according to the growth characteristics of strong trunks, obvious apical advantages, strong germination, and weak branching, and short fruiting branches as the main growth characteristics, it is necessary to grasp the large and small trees and the weak trees. Cut or not. Second, according to the size and strength of the pear tree, the pruning of the tree is considered, especially for different types of branches, different cutting methods should be adopted.
1. Backbone branches: The main branches, sub-main branches or other branches on the main branches shall be pruned mainly with short cuts. The pruning amount shall be appropriately increased, and the main branch angles shall be taken by supporting, pulling and hanging.
2. Branch group: It is the location of the fruit. The branch group that has been fruited in successive years should be kept strong and weak, and updated in time. Those branches that are horizontal, oblique and grow moderately and have full flower buds still allow them to grow naturally. Those with too many flower buds and new shoots growing short and weak should be appropriately short-cut, and thin and weak branches should be thinned. Those who are debilitated should be retreated more heavily.
3. Keeping branches: Where there is space in the canopy of the tree canopy, especially the vacant spaces between backbone branches at all levels, try to keep as many branches as possible. , Flower bud short in the second year), or retract after fruiting. If it affects the growth of the backbone branches, you can increase the angle, go straight to stay oblique, go strong to stay weak, and slowly release the results.
4. Fruit stand, short fruit branch: The fruit stand of the pear tree often sheds 1 to 3 auxiliary shoots. When pruning, it can be sparse and left one, or one short and one left. It can bear fruit and there are preparation branches. For short fruit branches, Pruning can be based on the total tree load to determine the amount of short fruit branches, thinning out excess short fruit branches, when the tree is weak, we must pay attention to thinning weak branches and weak buds. In addition, the leaves and branches should be kept strong and weak, and diseased insects, dry branches and dense branches should be thinned out.
Management after trimming
1. Disinfection in the garden to prevent and control various overwintering diseases and insect pests. After trimming, spray the stone sulfur mixture at 3 ° C to 5 ° C once or twice, and brush the trunk of the white pear tree with its sediment. At the same time, the scraped warped bark, deciduous dead branches, diseased insects and residual fruits will be burned and buried.
2. In the severe winter season, the orchard ground is covered with plastic film (or weeds, straws, etc.), or cold and frost, such as smoke.
3. After spring, apply spring fertilizer and irrigation early to improve the quality of flowering.
