Improved spindle-shaped fruit trees Free-spinning-shaped fruit trees Spindle-shaped fruit trees are characterized by a large number of main branches, with distinct subordinate relationships (central stem-main branch-result branches), distinct differences in roughness, and short and narrow diameters of tree bodies. Compact tree, no delamination, no lateral branches, single axis extension, results directly on the small main branch; main branch short, angled open, lower 3~5 small main branch horizontal or sagging, branch length no more than 0.5 meters, The entire canopy is elongated. The fruit tree adopting this tree structure has simple basic structure, convenient management, small amount of pruning, early results, good coloring of the fruit and excellent quality. When pruning, we must start from the "supporting the stem" and "miniaturization of the main branch" to quickly develop into a graceful tree with a strong, well-developed main stem and a short stem.
After the seedlings are planted, they are dried at 90 cm. Those who do not meet the height requirements will be short at full shoots and will be dry at 90 cm the next year.
In the spring, buds with a height of more than 60 cm above the main trunk were planted and budded at an interval of 15 cm. In the summer and autumn, when the new shoots are 30 to 40 cm in length, the shoots are made and branches are taken, and the shoot angle of the new shoots is maintained at 100 to 120 degrees. For new growth shoots, 2 to 4 twists and shoots should be taken.
In the first year of winter pruning, the branches within 60 cm above the ground surface are removed, and the branches are extended from the center to a short cut of 1/4 to 1/3 in the upper center. The competition branches are eliminated, and the rest of the new shoots are not placed in shear, and the branches are maintained at a branching angle of 100 degrees or more by twisting the tip and taking the branches. Exfoliate branches that are too dense or thick and equal to the trunk. Through the above treatment, the shoots are spaced 15 to 20 cm apart and arranged spirally on the center stem. The method of winter shearing in each subsequent year is basically the same as the first year. Generally, only short cuts are made on the central stem extension branches, and the other branches are slowly placed, and the dense branches and branches are removed. The ratio of branch to center dry thickness is always maintained at 1:3 and cannot exceed 1:2.
Summer pruning is mainly to eliminate buds, take branches, twist shoots, control branches prosperous, ease branching, promote flower bud formation, and cultivate uniaxial extension branch groups. For the perennial branch, when the resulting branch diameter exceeds 1/2 of the central stem, thinning should be carried out in order to trigger new shoots and cultivate new branches.
The key to reshaping the fruit-shaped fruit tree is to cultivate a strong center and to control the lateral branches through a strong center, ease the lateral branches, promote the formation of flower buds, and achieve the purpose of plastic crowning; The second is to pay attention to the timely renewal of the results of the branch, usually the results of the age of more than 5 years to be removed, and the use of sparse parts of the new branches re-cultivation, update the sticks to maintain the central stem and the result of the thickness of the sticks The ratio of the younger and younger groups.
