Why does plum tree pull branches?
Pulling branches and opening angles is the most commonly used method in plum pruning, which is to artificially change the growth direction of branches and make vertical branches oblique, horizontal or drooping.
This can effectively regulate the growth potential of branches, promote the formation of short branches and middle branches, promote the transformation from vegetative growth to reproductive growth, and blossom and bear fruit early.
1, adjust the tree structure, enlarge the crown, and accelerate the molding;
2. Improve the lighting conditions of trees;
3. Slow down the growth of trees;
4. It plays an important role in promoting flower bud differentiation and early fruiting.
Can plum trees 1 1 month pull branches?
Plum trees can be pulled not only in 1 1 month, but also all year round. Because time is not the only factor to decide whether to pull branches.
It is also related to many other factors, such as tree age, branch flexibility, opening angle, branch pulling method, plum variety, region and so on.
1, spring pruning
Pruning in spring should be completed before plum trees germinate as far as possible. This pruning technique is to supplement the unfinished work last year (plum trees only need to pull out the backbone branches, so try their best to do the work last year).
Step 2 pull branches in summer
This time, the branch was pulled at the end of May and the beginning of June. If the spring seedlings stop growing, there is no need to pull them out. If the spring seedlings stop growing during this period, they can be pulled out.
Step 3 pull branches in autumn
Autumn pruning refers to pruning from August 20th to September 30th. At this time, the branch pulling effect is the best. First, the angle setting time is short, and it can be fixed in about 10 days. Second, the autumn shoots will stop growing immediately, that is, the autumn shoots will be very short.
Step 4 pull branches in winter
Try not to pull branches in winter. Many fruit farmers pull branches because they have time in winter. Because the branches have stopped growing in winter and the degree of lignification is high, pulling out the branches will definitely hurt the bones and muscles, and there is no recovery time after pulling out the branches.
Why is it said that plum tree 1 1 month can pull branches?
1. The sap is still flowing and the branches are flexible.
1 1 The temperature in many places, especially in the south, is not very low and does not reach the dormancy temperature of plum trees, so many plum trees are in semi-dormancy or non-dormancy state.
This means that there is still a small amount of sap flowing and the branches have good flexibility. At this time, if you pull the branches gently and carefully, you can pull the branches successfully.
2. Suitable temperature and light
1 1 month, or late autumn, many places are not only suitable for temperature, but also sunny, warm as spring and crisp in autumn. So many places are suitable for plum trees to pull branches.
Moreover, during this period, there are few rainy days and many heavy rains, and even if there is branch pulling disease, it is not easy to be infected and rotted.
3. Not easy to suffer from pests and diseases
1 1 month, the weather is warm and cold, and the possibility of bacteria and eggs breeding and hatching is very small, and many pests and diseases are eager to hide. Therefore, it is not easy to be disturbed by pests and diseases even if pruning and pulling branches during this period.
4. More leisure time
1 1 month, the crops should be returned to the warehouse, and people have more leisure time. This time is naturally suitable for pruning plum trees.
What is the right angle at which plum trees pull branches?
The pruning angle of plum tree mainly depends on what kind of tree you choose. Today, taking our southern plum varieties as an example, the natural happiness is the main factor, and the happiness angle is 45 -60 degrees. For vigorous trees, the angle should be wider, on the contrary, the angle should be smaller.
