Abstract

The present invention relates to a rare earth pearl culture method which belongs to a culture method of pearls. In the present invention, young and small mussels, cell chips and mother mussels with pearls are processed by rare earth solution with proper concentration in the periods of pearl culture; the 200-300 ppm of rare earth (RE) is added in nourished soil, or the 0.1-0.2 ppm of RE is sprinkled in a water body for culturing the young and the small mussels, the cell chips are soaked and wounds are rinsed by the 500-1000 ppm of rear earth physiological saline, and the mother mussels with pearls are cultured in the method of injecting 0.5-1 ml of the 5000-50000 ppm of rear earth physiological saline, or soaking with the 80-500 ppm of rare earth solution and sprinkling the 0.2-0.2 ppm of rare earth solution into the water body. The pearl culture with the utilization of the method has the advantages of short pearl culture period, higher yield and quality of the pearl, and higher input-output ratio; the present invention is a pearl culture method with obvious economic benefit.

Description

Thin working pearl culturing method

Thin working pearl culturing method belongs to a kind of method for pearl culture.

The application of rare earth on crops is the frontier that rare earth is used, and China is first rare earth is used for agricultural production as commodity country, in these years the application of rare earth expands forestry, livestock breeding and fishery gradually to, but does not see the report of relevant rare earth cultured pearl as yet.

Conventional pearl culturing method, growth rate young, little freshwater mussel is slow, and the cultivation time is long, and 2-3 just reaches 8cm; The secretion of pearl matter is slow, and pearl production is low, and about every 3 gram, the cycle reaches 36 months; Pearl matter is low, and the top grade pearl is less than 28%.

The present invention is intended to explore the frontier that rare earth is used, and make pearl culture output with a new breakthrough is arranged qualitatively.

Realize that foregoing invention purpose technical scheme is: in each period of pearl culture, handle young, little freshwater mussel, cell small pieces and bosom pearl oyster freshwater mussel with the earth solution of debita spissitudo; Cultivate young, little freshwater mussel, then in educating the nutrition soil of freshwater mussel, add 200-300ppmRE, or the 0.1-0.2ppmRE that in the water body of culturing son, little freshwater mussel, splashes; Pair cell small pieces and wound then soak cell small pieces and flushing wound with 500-1000ppm rare earth normal saline solution; When culturing bosom pearl oyster freshwater mussel, can adopt injection or soak to combine with the method for splashing, injection i.e. injection rare earth normal saline solution from the abdominal foot ditch of freshwater mussel, and consumption is the 2-10mgRE/kg freshwater mussel, time be every month once, soak promptly and soak female freshwater mussel of cleaning with 80-500ppm rare earth liquid, consumption is the 2kgRE/kg freshwater mussel, soak time be every month once, each 2 hours, splash promptly to educating the freshwater mussel water body earth solution of splashing, making rare earth concentration is 0.2-0.3ppm, and the time is every month 1-2 time.

Be described in further detail the present invention below.

Rare earth has activation to some enzyme such as DNA enzyme etc. in the freshwater mussel body, can quicken Ca ⁺⁺Transhipment and alternative Ca ⁺⁺Effect, thereby can promote the growth of son, little freshwater mussel, the formation of pearl capsule, the pearl growth cycle is shortened in the secretion of pearl matter and the improvement of color and luster, improves output and the quality of pearl.

When cultivating son, little freshwater mussel, cultural method is routinely carried out, only need in nutrition soil, to add 200-300ppmRE, or the 0.1-0.2ppmRE that in the water body of culturing son, little freshwater mussel, splashes, splash water quality requirement PH＜7.5 of RE, transparency are greater than 35cm, splash 6-10 month sunny weather carry out, time is in morning during 8-10, every month 1-2 time.

When handling the cell small pieces, in 0.5% physiological saline, add RE, make it to contain RE500-1000ppm, when separating the outer embrane operation, soak the cell small pieces with this liquid then, irrigate with this liquid after operation is finished.

When culturing bosom pearl oyster freshwater mussel, can adopt injecting method to handle, be mixed with the earth solution of 5000-50000ppm earlier with 0.5% physiological saline, then freshwater mussel is strutted and jump a queue, injection rare earth normal saline solution 0.5-1ml from the abdominal foot ditch, (in per kilogram freshwater mussel 2-10mgRE), inject once in every month month of 6-9, or immersion process is handled when cherishing the pearl oyster freshwater mussel, be mixed with the rare earth liquid of 80-500ppm earlier with the PH6.5-7.0 clear water, female freshwater mussel of cleaning is put into the above-mentioned heavy rare earth liquid of two times of freshwater mussels that is made into, soak time is each 2 hours, in 6-9 month, soaked once in every month; Simultaneously can be to the water body of putting bosom pearl oyster freshwater mussel in a suitable place to breed the earth solution of splashing, first clear water with PH6.5-7.0 is mixed with the rare earth mother solution about 100,000 ppm, it is 0.2-0.3ppm that the amount of the rare earth mother solution in the bold and vigorous people pond makes the rare earth concentration in the pond, splash generally 6-10 month sunny weather the morning carry out during 8-10, require water quality PH6.5-7.5 when splashing, the not muddy transparency of water is splashed every month 1-2 time greater than 35cm.When handling bosom pearl oyster freshwater mussel, be used in combination with the method for splashing with a kind of in injection and the infusion method.

After adopting rare earth to handle each period of above-mentioned pearl culture, the growth rate of little freshwater mussel is accelerated 30-60%, 60% freshwater mussel can reach 6cm then, and the cycle of growing cultured pearls shortens 50%, and growing cultured pearls 16 months 50% only can reach 5.9g/, pearl production improves 20-90%, maximum product pearl is 22.5g/, and average 8.98/, top grade pearl ratio reaches more than 48%, improve 20 percentage points than original top grade pearl ratio 28%, go into operation than bringing up to 1: 5-20.

The present invention utilizes original technology and equipment cultured pearl of growing cultured pearls, simple, the processing ease of method, and the cycle of growing cultured pearls shorten, pearl production and quality have by a relatively large margin a raising.

Embodiment:

Young, little freshwater mussel breeding phase the nutrition soil that is mixed with 200ppmRE, is put into according to a conventional method to hang and is supported dish, adds the 0.2cm left and right sides freshwater mussel son who has just gone out the pond July, and density is 2.5/cm ², to culture 20-30 days, in August, young freshwater mussel is about 2cm, and the branch dish is added with above-mentioned nutrition soil equally in the dish, 0.8/cm of density ², cultured the long 3-4cm of children freshwater mussel in September, branch dish, same above-mentioned nutrition soil, the 0.3/cm of density of adding in the dish 20-30 days ², to culture 30-40 days, October, the children freshwater mussel reached 5.5-6.5cm, and then the branch dish, 0.12/cm of density ², in April, second, young freshwater mussel reaches 8cm more than 30%.
