困難を伴うことが多い。[0003] Oyster shells are used to prevent solidification of the soil in which shells live.
It is sprayed by making the soil pH slightly alkaline. However, when oyster shells are used in this way, the culture environment is deteriorated unless corrosive substances such as germs and shellfish attached to the shells have been removed, and the cultivation environment deteriorates. It is often difficult to collect the required amount of seashells from which seawater has been removed.

The type of shell can be used without any particular limitation. For example, shells such as clams, red clams, scallops, and oysters can be given.
Processing is carried out industrially, and there is also an advantage that a large amount of shells are generated and the shells can be obtained relatively easily. In general, a part of the shell meat is attached to the shell after collecting the shell meat, and the surface of the shell is covered with an organic substance called conchiolin.

一旦生成した炭素分が酸化分解されてしまう。By heat-treating the shell at a temperature of 350 to 600 ° C., the soil conditioner of the present invention can be obtained. By heat-treating the shell in this manner, organic matter such as conchirion on the shell surface is carbonized, and the resulting carbon content is included in the shell after the heat treatment, that is, the soil conditioner of the present invention. Sterilization of various germs attached to the shell can be performed. If the heat treatment temperature is lower than 350 ° C., carbonization of organic substances adhering to the shell and sterilization of various fungi are not sufficient. I will.

It is particularly suitable because it can be used as it is. The amount of carbon is sufficient to carbonize organic matter such as conchirion by heat treatment, and even if the amount is more than that, a significant effect cannot be obtained.

By heating the conchirion covering the shell surface and carbonizing the shell by heat treatment, calcium carbonate, which is the main component of the shell, is easily eluted, making the shellfish habitat soil suitable for the growth of shellfish. The effect of alkalinization is promoted, which has a positive effect on the growth of shellfish. The carbon content contained in the soil conditioner of the present invention promotes the effect of making shellfish patterns more distinct. Hereinafter, the present invention will be described in detail with reference to examples.

After spraying to a ratio of about m 2 , the clam larvae were released. Also, oyster shells conventionally used were sprayed under the same conditions as above in another place of the clam farm, and the same amount of juvenile clams were released. Six months later, clams were harvested from each location, and the amount of harvest and the pattern of the shells of the harvested clams were examined.
