BEST MODE FOR CARRYING OUT THE INVENTION The above-mentioned perlite used in the present invention is obtained by heating pearl foil to 700 ° C. to 1000 ° C. and foaming it, and is a porous body having sterility and light weight. The fact that perlite is a porous body having sterility and lightness is not only suitable as a material for a nursery medium for growing seedlings that requires good porosity and water permeability, but the purpose of the present invention is to have antibacterial properties. Considering that it is intended to provide soil, the sterility of perlite also indicates that perlite is a material for the purposes of the present invention.
Therefore, perlite occupies the largest part of the antibacterial seedling cultivation soil according to the present invention, and particularly forms the skeleton when formed into a mat form.

The above zeolites are natural and synthetic zeolites.
It exists in the form of (Zeolite), and it has been known in the past that each of the two types has characteristics as a catalyst in various forms of hydrocarbon conversion. One zeolitic material is a regular porous crystalline aluminosilicate having a certain crystal structure, as measured by X-ray diffraction,
Within this structure are a number of smaller cavities that can be interconnected by a number of smaller channels or pores. These cavities and pores are uniform in size within a particular zeolitic material. These substances are known as "Molecular Sleves" because these pores coalesce molecules of a certain size by excluding molecules of a larger size. Various attempts have been made to use it.
The above-mentioned properties of zeolite are very useful for growing seeds, and are components of the antibacterial seedling cultivation medium according to the present invention for promoting root growth, maintaining viscosity and suppressing expansion of the cultivation medium. Was adopted as.

When the above vermiculite is expanded at high temperature, it becomes a porous body having light weight and sterility. In particular, when water is supplied, not only the resilience is great, but also voids are formed inside the tissue, which contributes to the promotion of seed germination, especially root growth.

The above-mentioned fiber cellulose (fibrin) is also used as a material for menstrual bands and diapers,
It is necessary for maintaining a cohesive force between the components of the aseptic seedling cultivation soil according to the present invention and for organizing them. This is different from peat or coconut skin and has an antibacterial property as a straight fiber. By further containing the above-mentioned cellulose, it is possible to prevent the above-mentioned porous substance from collapsing or breaking the bond. Therefore, it is an essential component of the aseptic soil according to the present invention.

The above moisturizer is used as a water absorbing agent in physiological zones, diapers and the like, and is supplied in the form of particles (a typical product is "teracon" (polymer absorbent). ). 100 commercially available moisturizers
It is known that not only contains more than double weight of water but also has a function of suppressing evaporation. When the moisturizing agent is contained in the seedling-growing soil, the water of the soil can be continuously maintained during germination and growth by only watering by the user of the soil, which facilitates seedling raising.

The above-mentioned binder is water-soluble and enables the respective constituents of the seed and the soil to maintain the binding state in a dry state, and a typical one is commercially available "teracoat". When the soil according to the present invention is manufactured in the form of a mat, the binder binds to a moisturizer when water is supplied to form a film on the surface of the mat. This film prevents evaporation of internal moisture and prevents the external mold. Plays a role in preventing permeation. The above-mentioned popal is a powder made of polyvinyl alcohol and is used as an aqueous solution in the present invention. Popal has various characteristics of the soil component according to the present invention,
