Problems solved by technology

[0002] At present, the output of my country's freshwater pearls accounts for 95% of the world's total output, but my country's pearls only account for 6-8% of the world's total trade volume. The reason is that the quality and characteristics of my country's freshwater pearls do not have high quality and originality.

Embodiment 1

[0024] Lithium-rich pearls:

[0025] 1. Select the pearl mussels that have been recuperated after the operation, and raise them in separate ponds, with a density of 400-1200 pearl mussels / 667m for 1-2 years old. 2 , 3-5 years old pearl mussel 300-1000 / 667m 2 ;

[0026] 2. In the process of pearl mussel cultivation, during the annual pearl cultivation season, use substances containing trace element lithium (element, compound, organic matter) to make the content of trace element lithium in the pearl water body reach 0.005-0.200mg / L;

[0027] Specific methods: a. During the pearl growing season, keep the content of trace element lithium in the water body to 0.005-0.200mg / L for no less than 7-15 days per month, that is, the number of times of input of the substance containing trace element lithium per month is 3 5 times.

[0028] b. Change the water no less than once a month, but the water should not be changed within 5-7 days after the concentration of 0.005-0.200mg / L in the aquaculture ...

[0034] Ge-rich Se-Zn-Iron Pearl:

[0035] 1. Select the pearl mussels that have been recuperated after the operation, and raise them in separate ponds, with a density of 400-1200 pearl mussels / 667m for 1-2 years old. 2 , 3-5 years old pearl mussel 300-1000 / 667m 2 ;

[0036] 2. In the process of pearl mussel cultivation, during the annual pearl cultivation season, use substances containing trace elements germanium, selenium, zinc, and iron (which can be elemental, compound, or organic matter) to make the trace elements germanium, selenium and zinc in the pearl water body , Iron content reaches 0.005-0.200mg / L respectively.

[0037] Specific methods: a. During the pearl growing season, keep the content of trace elements germanium, selenium, zinc and iron in the water body to 0.005-0.200mg / L each month for no less than 7-15 days, that is, invest in the trace element germanium every month The frequency of selenium, zinc, and iron substances is 3-5 times.

[0038] b. Change the water no l...

Embodiment 3

[0044] Rich manganese molybdenum strontium boron rubidium pearl:

[0045] 1. Select the pearl mussels that have been recuperated after the operation, and raise them in separate ponds, with a density of 400-1200 pearl mussels / 667m for 1-2 years old. 2 , 3-5 years old pearl mussel 300-1000 / 667m 2 ;

[0046] 2. In the process of pearl mussel cultivation, during the annual pearl cultivation season, use substances containing trace elements manganese, molybdenum, strontium, boron, and rubidium (which can be simple substances, compounds, organic matter) to make the trace elements manganese and molybdenum in the pearl water body The contents of strontium, boron and rubidium reach 0.005-0.200mg / L respectively.

[0047] Specific practices: a. During the pearl growing season, keep the trace elements of manganese, molybdenum, strontium, boron, and rubidium in the water body at 0.005-0.200mg / L each month for no less than 7-15 days, that is, the monthly input contains trace amounts The number of ...

Abstract

The invention provides a cultivating method for increasing content of trace element of pearls. In the water body for cultivating pearls, the content of trace element needed in target pearl cultivationis improved so as to obtain pearls containing one or a plurality of trace elements. The invention overcomes the defects that the trace element is limit in the natural water body environment and the content of trace element of cultivated pearls is low and is even lack. The invention can cultivate pearls which are rich in trace elements or a plurality of trace elements, and the content of the target trace element can be improved by above 20% so as to improve the drug and edible quality of pearls, self-quality and selling price, improve the economic benefit of pearl cultivators and enhance the market competitiveness of the freshwater pearls. The invention is easy and simple to learn, has low cultivating cost and strong applicability, is favorable for popularizing and applying, in particularto various pearl farmers, and increases the financial income of pearl farmers.

Description

Technical field [0001] The invention relates to a culture method of pearls, in particular to a culture method for increasing the content of pearl trace elements. Background technique [0002] At present, the output of my country's freshwater pearls accounts for 95% of the world's total output, but my country's pearls only account for 6-8% of the world's total trade. The reason is that the quality and characteristics of my country's freshwater pearls lack high quality and originality. The poor quality and non-characteristic refers to the poor quality of pearls, low bead rate, poor gloss, and low nutrient content in pearls, especially the functional elements of trace elements such as selenium, lithium, germanium, zinc, etc. The content is low. In addition to making decorations, pearls are mainly used in medicine and health products. The effect of trace elements on the human body is well known. In addition, everyone knows that the source of trace elements in freshwater pearls is ...
