Common problems in shaping and pruning of fruit trees

Fruit tree is a kind of economic tree species, there are hundreds of known fruit trees, and all kinds of fruit trees have different planting areas in our country. When planting fruit trees, shaping and pruning is very important for its growth. Reasonable shaping and pruning can improve the permeability of fruit trees, promote the growth of fruit trees, and improve the rate of flowering and fruiting. But many friends do not have a correct pruning method, there are a lot of problems. The following editor is to introduce some common problems in fruit tree pruning.

1. The main branch is too low

Now in many orchards during the peak fruiting period, the location of the three main branches at the base of the fruit tree will not be more than 30 centimeters from the ground. This is very disadvantageous to the growth of fruit trees, because if the selection of main branches is too low, it will not only hinder the management of soil and pest control. It will also reduce the flowering and fruiting rate and affect the quality of the fruit. Especially if the main branch at the bottom of the fruit tree is too close to the root, the nutrient water of the main branch is absorbed too much, which leads to the growth of the bottom branch. The branches of fruit trees are strong at the bottom and weak at the top, which seriously affects the planting benefit.

2. Uneven growth

The uneven growth of fruit tree branches is due to the different growth progress of the main branches selected in the same year or before and after two years, and this difference will become more and more obvious with the delay of time. If this kind of branch is not pruned in time to adjust its growth, it will lead to more vigorous growth of overgrown branches and, on the contrary, weaker ones. The difference in growth ability between branches is getting bigger and bigger, so when we prune and select the main branches, we should pay attention to whether the branches grow evenly, and not blindly choose big branches and strong branches. Otherwise, it will lead to an uncontrolled increase in the number of branches, consume too much nutrition, and lead to a serious decrease in the rate of flowering and fruiting.

3. Improper handling of competitive branches

When choosing the main branch, many friends will take the competitive branch as the main branch, which is the backbone branch of the fruit tree, and its growth ability is very strong. And the angle between the competitive branch and the trunk is very small. If you do not do heart-picking, sprouting and other work on the competitive branch in the summer, and choose it as the main branch. The growth ability is very strong, it will be very troublesome to manage, and it will lead to the imbalance of growth between the main branches. And the base angle between it and the trunk is very small, if a large number of fruits are hung, it is very easy to cause the base to crack when picking or in strong wind. Therefore, we should prune competitive branches reasonably to avoid affecting the future growth of fruit trees.

4. there is no distinction between the main and the auxiliary.

When pruning the auxiliary branches, it is necessary to retract and remove them in time, and then open the angle to prevent the auxiliary branches from growing longer and longer, resulting in insufficient space for the growth of the main branches. There is no distinction between primary and secondary, the skeleton structure of fruit trees is very chaotic, can not see the branches on the haircut, to prevent the growth of each branch overweight, there is no primary and secondary. And when cutting the main branch, we should also pay attention to the pruning of the side branch to prevent the growth ability of the main branch from being weaker than that of the side branch. Pay attention to pruning strength to avoid the main branch is too weak, auxiliary branches are not supplemented, seriously affecting the growth of fruit trees.

The above are several common problems in fruit tree shaping and pruning, and we should also pay attention to branch pulling, pruning distance and main branch splicing strength when pruning. The pruning of fruit trees is very important and requires everyone to have certain skills, so we must pay more attention to it.
