Problems solved by technology

My own research shows that: when the dissolved oxygen content in the pearl pool is above 5mg / L, and the beneficial bacteria in the water body are above 85%, the pearl oysters will not only grow rapidly, but also be free from disease and injury; if the dissolved oxygen is below 5mg / L, even beneficial bacteria When the proportion of bacteria is as high as 90%, or the dissolved oxygen is above 5mg / L, but the proportion of beneficial bacteria is below 85%, poor growth of pearl oysters still occurs

Embodiment 1

[0011] Embodiment 1: (1), transformation of pearl cultivation ponds: DN15 inflatable pipes are erected at 5 cm from the bottom of the pond in the pearl cultivation ponds, one is laid every 3 m, and a diameter of 1 mm is opened on each pipe every 0.5 m. The air intake end is connected to the oxygen enrichment equipment, and the end is sealed without air leakage;

[0012] (2) During the peak season of pearl cultivation from April to October, start the machine and inflate for 5 hours at 11 o'clock on a sunny day to keep the dissolved oxygen content in the water not lower than 5mg / L;

[0013] (3) During the peak season of pearl cultivation from April to October, add beneficial bacteria at 9:00 on sunny days every 7 days, and the input amount is 1kg / mu, so that the number of beneficial bacteria in the water body accounts for more than 85% of the total number of bacteria.

[0014] After a period of cultivation test: compared with the control pearl, the yield of this method has been ...

Embodiment 2

[0015] Embodiment 2: (1), transformation of pearl cultivation ponds: erect DN40 inflatable pipes in the pearl cultivation ponds at a place 20cm from the bottom of the pond, lay one every 10m, and open a small hole with a diameter of 10mm every 2.0m on each pipe, and enter The gas end is connected to the oxygenation equipment, and the end is sealed without air leakage;

[0016] (2) During the peak season of pearl cultivation from April to October, start the machine and inflate for 1 hour at 16:00 on a sunny day to keep the dissolved oxygen content in the water not less than 7mg / L;

[0017] (3) During the peak season of pearl cultivation from April to October, add beneficial bacteria every 15 days at 12:00 on a sunny day, the input amount is 5kg / mu, and keep the number of beneficial bacteria in the water body accounting for more than 95% of the total number of bacteria.

[0018] After a period of cultivation test: compared with the control pearl, the yield of this method has bee...

Abstract

A method for cultivating pearls, including the transformation of a culture pond and the control of the number of beneficial bacteria and the oxygen content in the culture water, so that the entire culture ecology can be optimal. Advantages of the present invention: the present invention increases the dissolved oxygen in the water body, accelerates the decomposition of toxic and harmful substances, ensures that the water body is not hypoxic, improves the quality of the water body, and is beneficial to the growth of mussels; promotes the convection and movement of the water body up and down, and effectively utilizes the mussels to The intake of bait organisms; uniform nutrients and various elements in the upper, middle and lower layers of the water body, improve the algae phase and micro-ecological environment of the water body and facilitate the absorption and utilization of algae, improve the utilization rate of nutrients and various elements; promote mussels Growth can increase the pearl output by more than 20%, and the quality can be improved by more than 5 percentage points.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a pearl cultivation method. Background technique [0002] Since freshwater pearl culture was reintroduced from Japan in the early 1960s, it has developed rapidly in my country, ranking first in the world, accounting for 95% of the world's total. Although pearl cultivation technology has made great progress, there are also differences in cultivation technology and benefits. Some people have become billionaires, and some people have gone bankrupt. The reason is mainly due to differences in farming techniques. According to my research and practice on the key technology of freshwater pearl industrialization in the past 25 years, the creation of a pearl culture environment is the key to the growth of high-quality pearls and the success of pearl culture, especially whether there are diseases in pearl culture and the growth speed of pearls. My own research shows that: when the dis...
