Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a method of cultivating black seaweed, particularly a method of cultivating black seaweed using liquefied carbon dioxide gas.

(b) Conventional technology In the past, in the cultivation of black seaweed, urn-shaped fungi and other diseases such as IKm
This can lead to diseases such as reduced harvest and quality deterioration of black seaweed, so a drug called malachite green is used to suppress the diseases of black seaweed. .

In addition, acidic treatment is performed using an acidic solution containing citric acid as a main component to exterminate harmful green seaweed that grows mixed with black seaweed.

(c) The problem that the invention is trying to solve is that the chemical called malachite green is toxic, and the acidic solution containing citric acid as its main component may cause pollution if the waste liquid after use is poured directly into the sea. Therefore, it was necessary to carry out post-treatment to render it harmless, such as treatment with caustic soda.

The present invention has been devised to solve the above-mentioned problems in the conventional four-propagation of black seaweed, and uses simple means to suppress the occurrence of pathogenic bacteria that are harmful to the cultivation of black seaweed, and to exterminate green seaweed. The purpose of this study is to develop a cultivation method for black seaweed that can increase the reproductive height and improve the quality of black seaweed.

i24 [Means for Solving the Problems] The black seaweed cultivation method of the present invention is based on the method of cultivating black seaweed of the present invention. It is characterized by rapid freezing using soldering gas.

The most distinctive feature of the present invention is the use of liquefied carbon dioxide, which is used to stretch nets covered with black seaweed, slags, and other seaweed cracks from the sea.
This is dehydrated by appropriate means such as using a high-speed centrifugal dehydrator,
After that, the liquefied coal-fired gas was heated to I! in the refrigerator 4. JtD
! s+! Nip and quickly freeze to below -10°C. After the above-mentioned treatment with liquefied carbon dioxide gas for the required time, the 14 moss cracks protrude into the sea again and black seaweed grows.

(E) Effect Once the R4 moss cracks that had been pulled out of the sea and dehydrated were quickly frozen with liquefied carbon dioxide gas, carbon dioxide gas was dissolved in the water contained in the seaweed, and combined with the action of a weak acid, a black seaweed was generated. It is believed that urn-shaped bacteria and other pathogenic bacteria as well as green seaweed can be extremely effectively reduced or killed, and by providing light, the liquefied carbon dioxide gas activates the carbon dioxide assimilation effect of black seaweed itself. By activating the growth of black seaweed, it is possible to breed high-quality black seaweed that is glossy and does not discolor all the way to the tips of its leaves.

(f) Effects As explained above, the present invention aims to significantly reduce or kill green seaweed as well as pot-shaped bacteria and other pathogenic bacteria that hinder the cultivation of black seaweed, and to activate black seaweed. This method is effective in increasing the yield and quality of black seaweed.

Claims (1)

[Claims] A method for cultivating black seaweed, which is characterized in that nets, shells, and other seaweed cracks with black seaweed attached are once pulled up from the sea, dehydrated, and then rapidly frozen using liquefied carbon dioxide gas.
