Fruit tree winter shears, how to leave the kerf?

The fruit tree is trimmed with a saw, the technique is really simple, the branchlets are made of scissors, and the thick branches are sawed. However, the same branch, let different people do it, but it will have a completely different effect, the problem lies in the difference between the cut and the saw.

Take the back branch, the fruit farmers in many places like to leave a short pile when they are stripping their backs. As a result, in the coming year, not many dry piles are formed, or a pile of slivers emerges. When the back side and the back branch are removed, the cuts are kept very close, causing a lot of prosperous branches on the back side of the cuts in the coming year, but they are unable to make branches under the back, which makes the back more prosperous and the strips keep moving.

How to keep the cut? To achieve "sparse on the back, back side of the horse, back to stay buds." This means that when the branches are removed, the cuts should be flat and the piles should not be left; when the back branches are removed, the cuts should be downwards and outwards, as if they were horse ears. The advantage of this is that in the coming year, the branches will not be tied, and the branches under the cuts will not grow because they are close to the back.

When you want to get rid of the lower branches, you need to leave a bud to encourage it to make new branches in the coming year. It is also to "promote and suppress" and prevent the back from being stripped (because there is an advantage on the back). In this way, the back, back and back are mutually restrained, and the growth of the whole branch will be in a state of balance and stability, which is beneficial to the good flowering and good fruit.

Similarly, when you go to the big branch, you can also pay attention to it. You have to "saw the back of the tree, leave a centimeter, the slash should be flat, and the wound protection is good." When the saw is used, it should be sawed from top to bottom. The saw back should cover the tree body. The saw blade is slightly inclined outwards. The kerf is left in the shape of a horseshoe. The lower part of the slash is only 1 cm long from the trunk (so-called oblique sawing pile), saw The mouth must be flat. If it is very rough, use a knife to cut the side and finally apply a healing agent to protect the wound. This will not weaken the growth of the middle and the wounds, and the slash will not send too many branches in the coming year. This is because the scalloped flat oblique wound heals faster. If the kerf is attached to the tree body up and down, it will weaken the growth of the middle and is not conducive to the healing of the wound. If the shovel stays too long, it will be beneficial to the healing of the wound. However, in the coming year, many branches will be emitted from the upper and lower sides of the slash, which will waste nutrients.

Health Ingredients

Health foods contain a certain amount of functional health ingredients, which can regulate the functions of the human body, have specific effects, and are suitable for specific groups of people. General food does not have specific functions, and there is no specific range of people to eat. Health food cannot be directly used to treat diseases. It is a human body mechanism regulator and nutritional supplement.


The human body needs many nutrients, such as water, protein, fat, carbohydrates, vitamins, minerals, dietary fiber,etc. Nutritional products are generally rich in these nutrients and suitable for everyone. Its nutritional value of health ingredients is very high and it is suitable for everyone to drink. While health food is food with specific health functions and only suitable for specific groups of people, and its nutritional value is not necessarily high. Therefore, the various nutrients that the human body needs are still obtained from three meals a day. Of course, health care products are better in some aspects. Health care products can obtain more fixed health functions than nutrition products. The minerals of the human body are not balanced, so health care products have a greater advantage in some aspects.
