How to prune fruit trees

Prior to the fruit tree forming, the free-spindle shape with 35-meter row spacing was cultivated into a 65-meter-long happy-shape year after year. It was cultivated year after year for 7 years and formed for 10 years. High-quality, high-yielding fruit trees should be tall and dry, with good light, large shoots and small twigs, master-slave, and uniaxial extension. First, pruning order and thinking program 1. Trim to consider the three-year tree. 2. Turn around the tree for a few laps first. If you encounter a special tree shape for a few more turns, you can make a careful plan. 3. It is wrong to say that there are many branches and many results. It should be observed from different angles that the main branch with good orientation, good angle and suitable size should be 3-4, and the angle between the main branch and the ground should be 35 degrees. The first main branch is best left in the south, and the uppermost main branch cannot remain in the south. In short, it is low in the south, high in the west, and low in the west. The main branch has a spacing of 20-40 cm and spirally arranged in ascending order. The ratio of the main branch to the main trunk is 1:3-4. Second, pruning technology points 1. Permanent main branch trim. After the 3-4 year permanent branch is decided, the main branch is cut first, and the temporary branch will not fail. The main branch should be trimmed from the branch, that is, leave the head from the outside. On the main branch, more branches and less branches are needed. The side branches of the temporary branches give way to the main branches, and the side branches affect the side branches on the main branch. Offshoots should be removed. The distance between the lateral branches on the main branch is about 20 cm, and the ratio of the thickness of the lateral branch to the main branch is 1:3-4. The cultivation goal of the branch group is based on the loose ptosis type. 2. Temporary branches trimmed. Without prejudice to the growth of the permanent main branch, three to four temporary main branches per plant were selected to supplement the space and results. When the temporary main branch affects the permanent main branch, it must be transformed to make it clear from the main point. First, the large lateral branch and the large branch group should be removed. The second is proper retraction. Retreat to a moderately moderate or moderately large branch or branch with a large number of flower buds. Third, shaping the ideal model of the tree 1. The tree is about 2.5 meters high, with a permanent branch as the main, temporary main branch to supplement the happy-shaped basic framework. 2. 6-8 main branches of the whole tree, 3-4 permanent main branches and 3-4 temporary main branches, distributed between 1.5-2.5 meters on the main trunk. There is a clear distinction between the size of the permanent main branch and the temporary main branch, the branch group, and the pruning method, which are clear at a glance. 3. The branch culture and equipment are properly cultivated and there are enough quality flower buds. 4. The ratio of the thickness of trunk, main branch, lateral branch, and branch is appropriate, and the master and the follower are distinct. 5. The trees are well ventilated from top to bottom, from east to west, from east to west and north, and from inside to outside. The tree potential can be consciously adjusted and balanced, from strong to moderate, from weak to moderate. China Agricultural Network Editor
