Tie up standard All branches on the kidnapping side require binding. Tie branch is an auxiliary external force used for vines with poor dryness (ligninization) and cannot support themselves. If some branches are bound on the shelf surface, and some are not bound, it is easy to damage the overall stability of the tree. Tie and not die No matter whether you use binding materials such as U-shaped cards or cloth strips, it is not allowed to tie the branches tightly. However, the binding material cannot be moved on the steel strand and must be firmly fixed. There can be gaps between the branches and the tied materials, so that there should be room for thickening of the branches. The so-called "movement without moving, tied without death". Parallel arrangement To ensure that the branches are arranged parallel on the shelf surface, the distance between branches and branches must be equal. Generally, the Chinese family is required to be moderately weaker, such as Hongyang, Golden Peach, and Huayou, with a distance of about 25 cm; the Chinese family and the delicious family have strong vigorous tree species, such as Jinyan, Jinguo, Cuiyu, Hayward , Qin Mei, Xu Xiang and other branches are about 35 cm apart. Tie up method Traction tying is mostly used for putting the first fruit on the tree, using short-term pruning and weak tree rejuvenation and re-cutting. Because the branches are short, they cannot be pulled flat on the steel strands, and the tie is tied to the top of the branches and pulled to the steel strand. Straight buckle tying is the most common method of using U-shaped clips or tie bars to directly fasten the branches to the steel strands. This method is used for most normal summer cut trees. Binding requirements Light considerations Tie branches are not only the fixation of branches, but also the embodiment of wind resistance. The most important thing is the consideration of light energy utilization and the protection of photosynthesis, especially in areas with insufficient light. Therefore, prevent crowding, compaction, crossover, overlap and other binding phenomena that are not conducive to the use of light energy. Ventilation conditions Although ventilation and light transmission are usually relevant, ventilation actually has a more important role. Among the 16 elements required by plants, the top three are carbon, hydrogen, and oxygen. The so-called ventilation is the wind through carbon dioxide (photosynthesis is the use of sunlight to remove carbon dioxide and water in the air by plant leaves under light conditions). The process of synthesizing organic substances and releasing oxygen). Failure to ensure good ventilation will inhibit photosynthesis, reduce the synthesis and transformation capacity of organic substances, and directly affect yield. Therefore, the tied branches must be sparse and have a pre-design for the sprout of the next year. The shelf surface is flat. All the branches on the shelf surface should be at the same level by binding the branches, that is, the shelf surface should be flat, without three-dimensional or layered feeling. Whether tree potential and branch potential can show the golden mean, has a certain relationship with tying branches. More vigorous branches are tied flat or flattened, which will obviously restrain the top advantage and ease the branch potential, which will help balance the tree's potential and promote fruit production.

Pulling and tying refers to the method of using tying strips to pull the branches with strong stems that are upright or with a large angle to the shelf surface to forcibly flatten or reduce the angle to the shelf to fix the branches. On one branch, it is mostly in the middle and lower parts. Use this method.
Don't ignore kiwi fruit after winter cut
As a component of kiwi winter shears, tying branches after shearing has a very important meaning and effect. In terms of production, some growers have a vague understanding of this, and there is a lot of room for improvement and improvement. Based on long-term production experience, the following opinions are put forward on the binding of kiwi fruit branches after winter pruning for reference.
