1. Tree-shaped Pruning Technology of Red Fuji Fruit Suitable for Three-bud Pruning.

At present, the tree shape of apple trees is mostly small crown, sparse layer or spindle shape, and medium L-year-old branches on the main branches are selected, with the length between 9-40 cm.

Pruning method and effect of second and third bud scissors for red Fuji fruit trees

1. Winter pruning: leave 3 buds on the selected L-year-old branches (called base branches) in the first year, and send 3 branches in the second year. Generally, the first bud is a long branch with a length less than 40 cm. The second bud is a middle branch and the third bud is a leafy branch. When pruning in winter, three buds are left on the long branches, and the other two branches are not moved. If the hair branch is two long branches, take the 1 branch under the cut, and do the same 3-bud scissors on the second branch. This continues every year (too strong branches or too weak slender branches are thinned out). After 3-bud pruning for 2 consecutive years, at least L flower buds can be formed from the middle branches and foliage branches on the base branches, and flower buds can be formed after 3 or 4 years. The fruiting branches produced are also medium branchlets, which will become thinner after 2-3 years of continuous fruiting.

2. Summer pruning: 3. Bud grafting pruning is mainly in winter, and new shoots are not treated in summer. It is also possible to carry out 3-leaf and 3-bud shearing on back shoots and upright shoots in August, and the same effect as that of 3-bud shearing in winter can be achieved in the following year.

3. Advantages of three pruning techniques for red Fuji fruit trees.

(1) is suitable for Qiaohuaping fruit trees in arid and semi-arid areas, which overcomes the phenomenon of bare legs on the back of main branches and ensures vigorous growth.

⑵ The proportion of vegetative branches and fruiting branches in the branch group is moderate and stable.

⑶ This cutting method is practical and suitable for dwarfing apple trees.

⑷ This method is easy to learn and popularize.
