Embodiment 1

[0041] The factory environment of this embodiment: select a water area, which can be a water tank or a pond, etc., this embodiment uses a glass water tank 1, the water body has a PH value of 7.5-8.5, the water temperature is maintained at 15-28°C, and the water has sufficient dissolved oxygen; The water depth is 1-3m, and the water depth in this embodiment is 1m. The pearl mussel 4 is cultivated in the water, and the adjacent pearl mussels are kept at a distance, such as figure 1 Shown. At least one acoustic wave generator 2 is placed in the water area, and 40-50 days after the pearl mussel is implanted with the plant core, the pearl mussel is subjected to periodic sound wave stimulation, the sound wave frequency is 20-2000 Hz, and the sound wave stimulation time is 1 min-30 min each time. In this embodiment, The sound wave frequency is 20Hz, each stimulation time is 1min, and the sound wave intensity is 60dB.

[0042] 40-50 days after the pearl mussel 4 was implanted into the pl...

Embodiment 2-5

[0066] Example 2-5 : The difference between the four embodiments and the first embodiment is that different sound wave frequencies and sound wave strengths as shown in Table 1 are used for periodic stimulation.

[0067] Table 1 Acoustic frequency and intensity of Examples 2-5

[0068]

[0069] Comparative experiments: 5 comparative experiments corresponding to the above Examples 1-5 were carried out respectively. The difference between the comparative experiment and Examples 1-5 is that it lacks the sound wave stimulation process of the present invention, and the other contents are the same. The whole pearl culture experiment was carried out simultaneously with the above Examples 1-5, and the culture time was the same.

[0070] Through the comparison of Examples 1-5 with the corresponding comparative experiments, the results show that from the beginning of the first phase of sonic stimulation to 12 months later, the method of the present invention can increase the thickness of the ...

Embodiment 6-10

[0071] Example 6-10 : The culture environment in Examples 6-10: glass water tanks are used, the pH value of the water body is 7.5-8.0, the water temperature is maintained at 20-25°C, and the dissolved oxygen in the water is sufficient; the water depth is 2m, the pearl mussel is cultivated in the water, and the adjacent pearl mussels are kept At least one sound wave generator is placed in the water area, and the pearl mussel is subjected to periodic sound wave stimulation 40 days after the pearl mussel is implanted with the plant core, and the stimulation time is 30 minutes.

[0072] Acoustic stimulation is carried out in three phases, with 4 months as a period. The frequency of acoustic stimulation in each phase is as follows:

[0073] The first phase of acoustic stimulation:

[0074] First month: Stimulate once every 28 hours;

[0075] Second month: Stimulate once every 19 hours;

[0076] Third month: Stimulate once every 15 hours;

[0077] Fourth month: Stimulate once every 5 hours; ...

Abstract

The invention provides a sound stimulation method for promoting the secretion of pearl oysters. A water area is selected, the pH value of the water body is 7.5-8.5, the water temperature is maintained at 15-28 DEG C, and the dissolved oxygen in the water area is sufficient; the depth of water is 1-3 m, pearl oysters are cultivated in the water, and space is maintained between adjacent pearl oysters; and at least one sound generator is arranged in the water area, periodic sound simulation is carried out to the pearl oysters after 40-50 days since the pearl nucleuses are planted in the pearl oysters, the sound frequency is 20-2000 Hz, and the duration of sound stimulation each time is 1-30 min. The sound simulation is carried out by stages, each stage includes 4-6 months, and the simulation number of times in each stage gradually increases by taking month as the unit. The sound stimulation method for promoting the secretion of pearl oysters has the beneficial effects that the secretion of pearl oysters is promoted through sound simulation, the pearl sac is enabled to uniformly secrete by controlling the frequency and strength of sound, and the effects of shortening the growth period and improving the pearl-forming quality are played; and the operation is safe and convenient.

Description

technical field [0001] The invention belongs to the technical field of pearl cultivation methods, and in particular relates to an external physical stimulation method for promoting the secretion of pearl mussels, shortening the growth cycle, increasing the diameter of pearls, and improving the color of pearls. Background technique [0002] At present, there are problems such as thin pearl layer and uneven color in pearl products, which lead to the low quality of pearl ornaments. The reasons for the above phenomenon on the one hand are: the pollution of the breeding waters and the environment, the backward breeding technology, the lack of pollution prevention and control technology, etc.; Even excessive occupation of increasingly scarce farmland resources. In recent years, many places have proposed to reduce the area of ​​pearl cultivation, and have established specific procedures for fading out of this production field in the form of legislation. [0003] Pearl factory cul...
