Plankton propagation material, plankton propagation device and plankton propagation method

Abstract

The invention provides a plankton propagation material, plankton propagation device and plankton propagation method, which can enable fulvicin acid ferrum required for plankton propagation to be stably and persistently supplied into environment water for a long time. The plankton propagation material is made from a net-shaped container stuffed with granular iron materials, granular carbon materials and adsorbing materials, or made through combination of small boxes of a net-shaped container stuffed with the granular iron materials and the granular carbon materials and a net-shaped container stuffed with the adsorbing materials. The plankton propagation device is made through the steps of at least stacking one group of the plankton propagation materials and the small boxes of the net-shapedcontainers stuffed with leaf molds and loading the stacked groups into a greater net-shaped container. The plankton propagation method contains the step of placing the plankton propagation device inenvironment water for plankton breeding.

Description

technical field [0001] The present invention relates to a plankton growth material, a plankton growth device, and a plankton growth method using them. Background technique [0002] The earth is a planet of water and a planet of iron. Earth's creatures benefit from the bounty of iron. People can also become anemic if they are deficient in iron. The red color of human blood is caused by iron. Plants use iron to promote the production of the essential substance chlorophyll. However, iron, which is a key material, is extremely scarce in water. [0003] There are areas of the earth where vegetation does not flourish. Nitrogen and phosphorus are abundant in this sea area, but there are few plant plankton and the concentration of chlorophyll is low. This is mainly due to iron deficiency. When iron sulfate was scattered in this sea area, growth of plant plankton was confirmed. However, it is extremely difficult to disperse ferric sulfate continuously in a wide sea area. [...

AI Technical Summary

Problems solved by technology

Although various studies have been conducted on solving these problems, no specific method has been found

[0022] In addition, since graphite plates and iron plates have been used in conventional iron supply materials, the iron material will dissolve once a predetermined period of time has elapsed, requiring replacement.

But, according to fishery practitioners, replacement is nearly impossible

This is because: Due to the large number of uses, the replacement time cannot be guaranteed, that is, the above-mentioned replacement is incorporated into the daily work as a practical problem and cannot be solved.

[0023] In this way, it is necessary to simplify the replacement method of the iron material in the conventional iron supply material, but there is no specific method
