Fruit tree grafting generally uses more mulch film, and you can also use fresh-keeping bags, which is fine. The grafting tape has the function of fixing and moisturizing. There is really not so much emphasis on the raw materials. Using more than 100 imported glutinous rice paper grafting tapes and a few yuan of plastic strip grafting tapes will not have a great impact on the survival rate of the graft. It is just that the imported glutinous rice paper grafting tapes are easier to use and can be dissolved later without any human factors. It is more convenient to remove the grafting tape. Generally, it is better to use mulch film as the most commonly used grafting tape. Buy a roll of mulch film and cut it into small sections to tie up the grafting joint. The mulching film is relatively thin. Wrap a layer around the bud point area. The bud point can lift the grafting tape. However, the back of the mulch film cannot be interpreted naturally. If the grafting interface continues to expand later, the grafting tape must be touched manually. Otherwise, the expansion of the protoplast and grafting interface will be restricted, and the grafting tape will be inserted into the enlarged callus, which will have a negative impact on the saplings. Growth and development are not good.

Of course, some old fruit farmers even use tape when grafting. As long as the sealing is tight, the graft can survive. If you understand the role of the grafting tape, you can easily give full play to it. Some red grape projects do not even use grafting tapes for grafting seedlings. Red grape grafting usually uses rootless grafting in large quantities and is produced on an assembly line. A grafting machine is used to pick up a bud point at the top of a stick-wood branch, usually in a U shape. There are many graftings, and then the grafting tape is not tied up and fixed directly with grafting wax. Generally speaking, there are two types of grafting wax, healing wax and fixing wax, which are used at different times during the red grape season. China already has this It is a production model similar to assembly line production.

Apple tree grafting is divided into bud grafting and bud grafting. Branch grafting is carried out in the spring (usually late April) before the fruit tree buds, while bud grafting is carried out after the development of the fruit tree has stopped in the spring, that is, 6--7 The weather varies across the country during the month. The branches used for grafting are first of all non-toxic, do not contain many bacteria, are all good species, and have round buds. It is very important to choose a good climate. The temperature is high and it is easy to survive. If it is rainy, you cannot choose to graft. Commonly used grafting methods Carving knives and sharpeners must be sterilized. After grafting, they can be wrapped with mulch film or fresh-keeping bags. The mulch film can be 7-8 cm wide. The thickness does not matter. When wrapping, wrap it from top to top. , no gaps are exposed to prevent water or stains from entering and affecting the survival rate. The wrapping process is important and fixed well, so that the grafting position can be affinity.

In addition, before survival, the buds should be wiped immediately to remove the buds emerging from the sticky wood position. This can reduce nutrient consumption and promote the early survival of grafted young leaves, which is particularly important. What kind of binding is best for fruit tree grafting depends on what kind of wiring method you choose. It is best to bundle all bud grafting with a 1 or 5cm wide stretch plastic film bag. It must be wet and there is It is malleable and will not easily sink into the surviving and enlarging buds. Such as organic fertilizer bags, tissue packaging bags, etc., you can turn waste into treasure by adding it yourself. If it is bud grafting (including bridge pressing), it is not possible to use plastic film. You need to use plastic film rope, which can withstand tensile force, can be tightly wrapped, moisturizing, and can be firmly tied. Since bud grafting is not a single bud, but at least 2 to 3 buds, it will still be like a small sapling after survival. It is easy to shake when exposed to wind, and the survival rate of Zatai Pine will be greatly affected.
