Problems solved by technology

It often leads to unstable calcium concentration and short-term effect, so that pearl mussels cannot absorb the calcium needed for a long time and convert it into active calcium that can form high-quality pearls
As a result, the proportion of low-quality pearls in the current market is as high as 60%, making China's pearl industry at a disadvantage in international competition

Embodiment 1

[0009] Embodiment 1: Get 650 grams of calcium oxide with a particle maximum diameter of 0.06 mm, get 250 grams of clam shell powder with a maximum particle diameter of 0.02 mm and add 50 grams of acetic acid for acidification, and above-mentioned calcium oxide, clam shell powder after acidification treatment Fully mix with 30 grams of compound amino acids, 5 grams of vitamin D and 15 grams of calcium-binding protein to make a freshwater pearl mussel calcium source, and then put the above freshwater pearl mussel calcium source into a bag of 150 grams per bag with a surface aperture of 0.07 mm Serve in the packaging bag.

[0010] The method of use is: a. How to put the calcium source: hang the calcium source packed in the packaging bag into the water together with the pearl clam, and control the amount of feeding at 25 grams per cubic water body; b. The number of times the calcium source is put in: spring 1 time / 30 days, 1 time / 20 days in summer, 1 time / 40 days in autumn, c. The...

Embodiment 2

[0011] Embodiment 2: Get 510 grams of calcium oxide with a particle maximum diameter of 0.08 mm, get 380 grams of clam shell powder with a maximum particle diameter of 0.05 mm and add 40 grams of acetic acid for acidification, and above-mentioned calcium oxide, clam shell powder after acidification treatment Fully mix with 40 grams of compound amino acids, 3 grams of vitamin D and 27 grams of calcium-binding protein to make a freshwater pearl mussel calcium source, and then put the above freshwater pearl mussel calcium source into a bag of 200 grams per bag with a surface aperture of 0.09 mm Serve in the packaging bag, all the other are with embodiment 1.

Embodiment 3

[0012] Embodiment 3: Get 750 grams of calcium oxide with a particle maximum diameter of 0.09 mm, get 150 grams of clam shell powder with a maximum particle diameter of 0.06 mm, add 20 grams of acetic acid for acidification, and above-mentioned calcium oxide, clam shell powder after acidification treatment Fully mix with 45 grams of compound amino acids, 5 grams of vitamin D and 30 grams of calcium-binding protein to make a freshwater pearl mussel calcium source, and then put the above freshwater pearl mussel calcium source into a bag of 100 grams per bag with a surface aperture of 0.1 mm Serve in the packaging bag, all the other are with embodiment 1.

[0013] After the freshwater pearl mussel calcium source was used by the pearl mussel farm in Fuquan Town, Shaoxing County and the pearl mussel farm in Pingshui Town, Shaoxing County, the output of high-quality pearls increased by 10-20%. If the present invention is popularized and applied, even if only about 30% of farmers adop...

Abstract

The invention discloses a mussel calcium source for pearl cultivation in fresh water and manufacturing and using methods thereof. Each 1000g of mussel calcium source comprises 400-850g for calcium oxide, 100-450g for mussel shell powder, 10-100g for vinegar, 10-100g for compound amino acid, 1-10g for vitamin D and 5-40g for calcium binding protein. The manufacturing method is that: a. the calcium oxide is mashed; b. the mussel shell is mashed and then added with vinegar for acidification; c. the materials from steps a and b are fully mixed with compound amino acid, vitamin D and calcium binding protein to form mussel calcium source for pearl cultivation in fresh water; d. the mixture is packed. The using method is that: a. the calcium source packed in bag is suspended to water with mussel shell for cultivating pearl; b. the times for suspending calcium source are that: one time / 30 days in spring, one time / 20 days in summer and one time / 40 days in autumn; c. the temperature surrounding the calcium source is kept between 15 DEG C and 35 DEG C. The invention has the advantages of scientific prescription, low cost, easy usage and being capable of effectively improving fresh water pearl output and quality.

Description

technical field [0001] The invention relates to a calcium source and its production and use method, especially related to the freshwater pearl mussel calcium source and its production and use method. Background technique [0002] After more than 30 years of development, the production of freshwater pearl cultivation has reached more than 1,000 tons, with an annual output value of more than 4 billion yuan. Yet along with the increase of pearl output in recent years, the quality problem of pearl is increasingly serious threat to the development of this breeding industry. Pearls are composed of 90% to 95% calcium carbonate, 10% to 5% conchiolin, a small amount of water and inorganic salts. The formation of high-quality pearls is mainly limited by two aspects: one is the source of calcium; the other is the rate of calcium absorption and secretion by the mantle and pearl sac. And in the existing actual production, people often use quicklime (calcium oxide) as the most economica...
