A kind of ecological pearl breeding system for pearl cultivation and using method thereof

Abstract

The invention discloses an ecological pearl cultivation system for pearl cultivation and a method for using the same, which belong to the technical field of freshwater cultivation. The ecological pearl cultivation system for pearl cultivation can provide pearl cultivation for pearl mussels through scientific and reasonable cultivation management. Optimum growth environment, at the same time adopts the method of precise feeding, provides nutrients to pearl mussels based on the principle of slow release, does not need a large amount of fertilizer feeding to ensure the nutrient intake of pearl mussels, with a smaller amount of nutrients To achieve the same feeding effect, thereby reducing unnecessary waste, on the one hand, it is convenient for pearl mussels to absorb nutrients effectively and quickly, on the other hand, it can reduce the probability of water eutrophication, and prevent water pollution from threatening the growth of pearl mussels In addition, water hyacinth can also be used to absorb excess nutrients to prevent eutrophication of water bodies, and water hyacinth can be used as a raw material for nutrients to complete the transfer and recycling of nutrients to achieve maximum utilization of resources.

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
