Problems solved by technology
Later, due to the excessive production of pearls and improper breeding management, the production of pearls began to decline.
And there are many problems brought about by pearl farming, such as: disease, water pollution, poor pearl quality, etc.
[0003] Among them, water pollution has become a hot topic in the current society. Due to the excessive use of fertilizers and bait in the water during breeding, water quality pollution and damage to the water body have been caused. Environmental pollution has also forced relevant policies in many places to suppress and reduce the breeding area. Lead to the decline of the pearl industry, which also brings bad economic benefits to the farmers of pearl mussels

Embodiment 1
[0046] see figure 1 , a freshwater pearl harmless cultivation method, comprising the following steps:
[0047] Step 1, the establishment of breeding ecology, set up isolated pearl mussel culture ponds, original aquaculture ponds, and water purification ponds, wherein the pearl mussel culture ponds are divided into juvenile mussel culture ponds and adult mussel culture ponds, juvenile mussel culture ponds and adult mussel culture ponds. The breeding pond, the original aquaculture pond and the water purification pond are all provided with a water inlet and a water outlet. The water outlet of the juvenile clam cultivation pond is connected with the water inlet of the adult clam cultivation pond, and the water outlet of the adult clam cultivation pond is connected with the water outlet of the original aquaculture pond. The water inlet is connected, the water outlet of the original aquaculture pond is connected with the water inlet of the water purification pond, and the water outl...

The invention discloses a method for harmless cultivation of freshwater pearls, which belongs to the field of cultivation of freshwater pearls. It relates to a method for the cultivation of freshwater pearls for harmless cultivation. The establishment of breeding ecology includes the establishment of mutually isolated pearl mussel cultivation ponds, original aquaculture ponds, water Purification pool, in which the pearl mussel culture pool is divided into juvenile mussel culture pool and adult mussel culture pool, which are formed by establishing mutually isolated juvenile mussel culture pools, adult mussel culture pools, original aquaculture pools and water purification pools, and connected by circulating pumps A circular circulation aquaculture system, through the separation and utilization of water in different aquaculture ponds, the fully utilized water is passed into the water purification pond for electrolysis and filtration, which effectively reduces the content of nitrogen, nitrate nitrogen and harmful substances in the water, and realizes the waste water It is converted into raw materials, and then the processed raw materials are circulated into the culture ponds at all levels, which not only purifies the water body of the whole culture system, but also saves costs and reduces the degree of environmental pollution.
Description
technical field [0001] The invention relates to the field of freshwater pearl cultivation, in particular to a method for harmless cultivation of freshwater pearls. Background technique [0002] With the continuous expansion of the pearl farming industry, my country's pearl production has also continued to increase. It reached its peak in the past few years, with an annual output of more than 4,000 tons. my country has also become the world's largest producer of freshwater pearls. Later, due to excessive pearl production and improper breeding management, the pearl production began to decline. And there are many problems brought about by pearl cultivation, such as: disease, water pollution, poor quality pearls and so on. [0003] Among them, water pollution has become a hot topic in the current society. Due to the excessive use of fertilizers and bait in the water during breeding, water quality pollution and damage to the water body have been caused. Environmental pollution h...
