The present invention relates to a grafting method. More specifically, the present invention relates to a grafting method in which the binding property is significantly improved by using a film that exhibits self-adhesive properties during film stretching as a binding material. Generally, continuous cultivation of agricultural products in the same field, that is, continuous cultivation, tends to cause diseases and reduces yield, so continuous cultivation is usually avoided. In recent years, with the development of greenhouse horticulture, continuous cropping has been adopted for efficient operation of facilities, and the technology for continuous cropping has also improved significantly. One of these is the creation of grafted seedlings that are resistant to continuous cropping. What is a grafted seedling?
For example, a seedling that is obtained by grafting a tomato, which is weak against continuous cropping, using a pumpkin, which is resistant to continuous cropping, as a rootstock.A seedling obtained by grafting the desired plant using a closely related plant that is tolerant to continuous cropping as a rootstock. It is. The use of grafted seedlings is essential, especially for plants belonging to the cucurbits and eggplants, and this has led to the rapid development of greenhouse horticulture.
It is also useful in a wide range of applications. Furthermore, for fruit trees such as mandarin oranges and apples, a method of growing roots from a part of the mature tree and growing them as seedlings, the so-called tree method, is also widely practiced. In the case of grafting, the rootstock and scion must be brought into close contact with each other, and the grafted area must be firmly fixed or covered to prevent water from entering. In the case of tree cuttings, the cambium layer of the branch that is to be used as a seedling is removed and wrapped in water, covered with water, and tied.
This area must not be allowed to get wet or dry. For a binding material suitable for these uses, two things are essential: it can be firmly fixed, and it can prevent water from entering from the outside and preventing it from drying out. Polyvinyl chloride or polyethylene film is used as a binding material that satisfies these two points, but the ends of the tape-shaped film must be tied. Therefore, a considerable amount of time is required for binding during the grafting process. Furthermore, it is difficult to tie the film tightly so that it does not loosen. I tried using adhesive tape instead of tying the end of the film, and was able to tie it tightly to prevent it from coming loose, but it was necessary to use a different adhesive tape than the film used for binding. Therefore, it took almost the same amount of time as tying up a film terminal. In addition, if water or mud adhered to the area where the adhesive tape was applied, it would peel off easily, making it not very practical to use adhesive tape in the case of lumber. I also tried grafting using only adhesive tape, but since the tape is sticky from the beginning, it becomes sticky and difficult to handle.When stretching the adhesive tape, the difference in characteristics between the film support of the adhesive tape and the adhesive causes problems at the interface. The binding material is bad because it causes peeling and a decrease in adhesive strength.Since the adhesive comes into direct contact with the graft, it has a negative effect on the growth of the plant, resulting in a decrease in the binding workability and the survival rate of the graft.Adhesive tape Grafting alone was also not practical. In view of this situation, the present inventors conducted extensive research and found that when a film that exhibits self-adhesive properties when stretched is used as a binding material for grafts, binding can be completed by slightly pulling the ends, and further They continued their research and finally completed the present invention. That is, according to the invention, polyisobutylene 30~
A grafting method is proposed, which is characterized in that a film consisting of a resin composition of 60% by weight, 10 to 40% by weight of polyethylene, and 15 to 60% by weight of paraffin wax is used as a binding material. The term “grafted” here includes grafted wood. The same applies below. The polyisobutylene used in the present invention is a polymer whose main component is isobutylene, and has a molecular weight of 200,000 to 200,000.
1.5 million. Of course, homopolyisobutylene can also be used. The polyethylene may be one polymerized by either a high-pressure method or a low-pressure method, and vinyl monomers copolymerizable with ethylene, such as vinyl acetate, propylene, 1-butene, 4-methyl Copolymers of ethylene with α-olefins such as -1-pentene, acrylic acid and its esters may also be used. Next, as a paraffin wax, its melting point is 60.
~80°C is preferred. It is also possible to use isoparaffin and oligomers of α-olefin such as ethylene and propylene, which are used in combination with normal paraffin. The amount of parfine wax blended is preferably 15% to 60% by weight. If the amount is less than 15% by weight, the self-adhesion will be weak or very small when the film is stretched, and if it exceeds 60% by weight, it will be difficult to form the film, or even if the film can be formed, the self-adhesion will be weak during stretching. There is a problem that the film does not stretch very much and breaks. These components are used by mixing them in the above proportions, but in addition to these, commonly used resin additives such as antioxidants, antistatic agents, pigments, fillers, etc. can also be added. The total amount of these additives is suitably 20 parts by weight or less per 100 parts by weight of the above composition; if this exceeds this amount, stretchability or self-adhesiveness during stretching is often lacking. Further, depending on the purpose, chemicals such as fungicides and rooting promoters may be added to the above composition. The composition obtained by a conventional kneading method is formed into a film by a known means such as a calendar method or an extruder. Note that the thickness of the film is preferably about 50 to 200 μm. The film obtained in this way does not have self-adhesive properties as it is, but by stretching the film and applying self-adhesive properties to the grafted area, it has both waterproofing and fixing functions just by wrapping it around the grafted area. fulfill. That is, terminal processing, which was complicated with conventional binding materials, becomes easier. For this reason, the workability of grafting is greatly improved, 2 to 3 times that of the conventional method, and it is possible to securely bind the grafts. If the composition ratio is outside the above range, the film may already be sticky before stretching, and the film may block and the roll may not be peeled off, or the film may be too hard and hardly elongate, requiring bundling, etc. Many of them are unsuitable for this purpose. Hereinafter, the present invention will be specifically explained with reference to Examples. Example (i) Polyisobutylene (R
-1) or 1 million polyisobutylene (R-2), (ii) polyethylene and (iii) melting point approximately 60℃
The following paraffin waxes were blended in the composition ratio shown in Table 1 and kneaded using oven rolls. This kneaded material is extruded onto a metal surface through a T-die at a temperature of about 180℃ using a single-screw extruder to form a sheet A of about 100μ.
~F was obtained. This sheet was cut into tapes with a width of 2.5 cm and used as a binding material. A Kabochinya plant before true leaves appeared was used as a rootstock, and a tomato seedling with one or two true leaves was grafted onto it. Table 1 shows the number of seedlings processed per minute and the graft survival rate at that time. Comparative Example 1 Table 1 also shows the results of grafting using tapes G to K obtained in the same manner as in the example with the composition ratios shown in Table 1. Furthermore, for comparison, polyvinyl chloride film (trade name: Mitsui Vinyl, manufactured by Mitsui Toatsu Chemical Co., Ltd.,
thickness 100μ) and polyethylene film (thickness
Table 1 shows the results obtained by making a 2 cm wide tape of 100μ) and using it for grafting. It took time to bind the ends of polyvinyl chloride film and polyethylene film tapes.

[Table] is shown in Table 1. Since the tape was sticky from the beginning, it took time to tie it together. As is clear from the table, the grafting method of the present invention significantly improves the workability of grafting compared to the conventional method using binding materials, and also improves the graft survival rate because the binding is more reliable. There is.
