Ecological pearl cultivation system for pearl cultivation and use method thereof

Abstract

The invention discloses an ecological pearl cultivation system for pearl cultivation and a use method thereof and belongs to the technical field of freshwater breeding. The ecological pearl cultivation system for pearl cultivation can provide an optimal growth environment for pearl cultivation mussels through scientific and reasonable breeding management, adopts a precise feeding mode to provide nutrient substances for the pearl cultivation mussels on the basis of a slow release principle, ensures the nutrient substance intake of the pearl cultivation mussels without massively putting feed, achieves the same feeding effect with fewer nutrient substances, and thus reduces unnecessary waste. On the one hand, convenience is provided for the pearl cultivation mussels to effectively and quicklyabsorb the nutrient substances; on the other hand, the probability of eutrophication of water can be reduced, and water pollution is prevented from threatening the growth of the pearl cultivation mussels. In addition, water hyacinth can also be used for absorbing redundant nutrient substances to prevent the eutrophication of water and adopted as a raw material of the nutrient substances, transferring and recycling of the nutrient substances are completed, and the maximum utilization of resources is realized.

Description

technical field [0001] The invention relates to the technical field of freshwater aquaculture, and more specifically, relates to an ecological pearl cultivation system for pearl cultivation and a use method thereof. Background technique [0002] As a colorful, dazzling, rare and precious decoration, pearls are deeply loved by the public, and can be refined into various necklaces, bracelets, ornaments and other decorations through processing. Pearls are rich in amino acids and a variety of trace elements, so they are also valuable Chinese herbal medicines, which have the effects of clearing away heat and detoxification, calming nerves, calming convulsions, improving eyesight and relieving pain, and astringing and promoting muscle growth. [0003] Pearls can be divided into natural pearls and cultured pearls. At present, more than 90% of pearls on the market are cultured pearls, and cultured pearls can be divided into seawater pearls and freshwater pearls. With the continuous ...

AI Technical Summary

Problems solved by technology

[0004] Artificially cultured pearls have a long history in our country. They are mainly hanged and raised in natural waters such as rivers and lakes, or in natural and artificially dug ponds. Usually a small amount of filter-feeding fish are mixed in the water, and organic fertilizers are sprinkled into the water. or chemical fertilizers to cultivate planktonic crops as bait for pearl mussels. However, if a large amount of organic fertilizers or chemical fertilizers are used, river mussels cannot absorb them all at once after feeding them in conventional culture, resulting in a large amount of organic matter precipitation, which is easy to cause eutrophication in the water body. At the same time, a large amount of fish feces and leftover bait residues are deposited at the bottom of the water body, resulting in the continuous accumulation of organic matter at the bottom of the water body, which is easy to ferment and produce carbon dioxide, resulting in severe hypoxia in the water body and imbalance of pH, which can easily lead to low pearl production and even the death of pearl oysters. And the direct discharge of polluted water can easily cause environmental pollution and even threaten human health
