The purpose of winter orchard pruning is to produce high quality and high quality in the coming year, but if the pruning method is not correct, it will not increase production, but also endanger the normal growth of fruit trees. Here are some common mistakes made during winter plastic pruning. Be careful.
Winter pruning these mistakes to avoid
1, do not take thinning
For winter pruning, the two points considered are group confinement and lighting problems. If it is an orchard with fruit hanging for years, the branches and leaves must be crossed and overlapped, and the row spacing and plant spacing form a closed state. It has long been inconsistent with ventilation and light transmission conditions. Therefore, if it is not trimmed, it is difficult to achieve the purpose of quality improvement. However, there are many garden owners who are afraid of affecting production. They are always unable to worry and raise their legacy. As a result, investment and investment have increased year after year, while both production and quality have been declining year by year.
2, do not remove the big branches
Due to the traditional old-fashioned pruning method, the lateral branches of the fruit trees are thick and large, and the branches are out of the knot. The upper and lower branches are weak or weak, the branches and branches are too many, the branches are not coordinated, and the branches are moved outwards, resulting in tree potential. Virtual or weak, can not produce high-quality goods. However, there are many garden owners who have been able to cultivate a big branch for many years, let them continue to grow, and the pruning staff can't stand the obstacles of the owner, and they will squat down the slope.
3, do not combine pull branches
The traditional pruning mode is “winter cut, no matter all year roundâ€. For the branches with small branches and the oblique branches on the branch, the winter is not removed, the summer is not pulled, and the ring cutting or peeling is used. The result of the flowering is eventually caused by the tail, and in the later reforming process, the trouble of excessive damage is often encountered. For the branches on the back, oblique branches, and small branches, there is no space to kill year by year, there is space for the summer to pull, can not be soft and pity.
4, look at the flower trim
Regardless of the big and the young, regardless of the long branches and short branches, regardless of the tree and tree shape, regardless of the new branches and old branches, see the flowers stay, no flowers, the result is "full tree flowers, half tree fruit", fruit There are few small leaves and small leaves, and the tree is weak and the skin is burning. Pruning must grasp the potential, shape, degree, and quantity, and must grasp the ratio of leaf to fruit, the ratio of branches and the ratio of the pruning. Don't do it with this saw, don't cut it.
5, back to shorten the cut
In the long-term fruit-bearing period, Fuji, banned retraction and short cuts, blindly retracted and short-cut, not forming a "small old tree", is the formation of "a swarm of bees." For the uniaxially extended leader branch, it is necessary to reserve the back and the lower branches for the branch angle change, but not for the side branches to take the scam; for the successive years, the branches are weak, and the branching branches are drooping. High branch angles, the branch group should be replaced, and the retraction and short cuts cannot be performed.
