Description

A self-purifying small circulation pool system for germplasm resource protection

technical field

The invention relates to a self-cleaning small circulation pool system for germplasm resource protection, which belongs to the technical field of aquatic equipment. the

Background technique

Germplasm resource protection usually adopts natural breeding ponds, because natural breeding ponds are closer to natural ecosystems, natural ecosystems are conducive to the growth of aquatic animals, and the water quality is better, but natural breeding ponds are generally used for germplasm resource protection. The stocking density will be greatly reduced, which is not conducive to fish sampling, and the fish body is vulnerable to damage during the fishing process. The cement pool in the greenhouse is difficult to circulate due to the lack of self-purification ability. At the same time, due to the lack of competing organisms such as bacteria, it is easy to breed algae. Appropriate algae can increase the oxygen content of the water, but too much algae will deteriorate the water quality. Planting water hyacinth and other floating plants directly in the pond can remove algae, but the floating plants multiply rapidly and will cover the water surface, thereby affecting the contact between the water surface and the air and affecting the oxygen content of the water. Therefore, the cement ponds in the greenhouse are often not suitable for long-term maintenance Conservation. the
