Embodiment 1

[0040] The factory environment of present embodiment: choose a water area, can be water tank or pond etc., present embodiment adopts glass water tank 1, and water body pH value is 7.5-8.5, and water temperature remains on 15-28 ℃, and dissolved oxygen in water is sufficient; The depth of water is 1-3m, and the depth of water of the present embodiment is 1m, and 4 pearl mussels are cultivated in the water, and the adjacent pearl mussels keep the distance, such as figure 1 shown. Place at least one infrasonic wave generator 2 in the water area, and perform periodic infrasonic wave stimulation on the pearl mussel 40-50 days after the pearl mussel 4 is implanted into the plant nucleus. In this method, the frequency of infrasound wave is 1Hz, the time of each stimulation is 1s, and the intensity of infrasound wave is 30dB.

[0041] 40-50 days after the pearl clam was implanted into the nucleus, 45 days were selected in this embodiment, and the infrasonic stimulation was carried ou...

Embodiment 2-4

[0065] Example 2-4 : The difference between these 3 embodiments and embodiment 1 is: adopt different infrasonic frequency and infrasonic intensity as shown in table 1 to carry out periodical stimulation.

[0066] The infrasonic frequency and intensity of table 1 embodiment 2-4

Abstract

The invention provides an infrasound 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 infrasound generator is arranged in the water area, periodic infrasound simulation is carried out to the pearl oysters after 40-50 days since the pearl nucleuses are planted in the pearl oysters, the infrasound frequency is 1-18 Hz, and the duration of infrasound stimulation each time is 1-10 s. The infrasound 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 infrasound stimulation method for promoting the secretion of pearl oysters has the beneficial effects that the secretion of pearl oysters is promoted through infrasound simulation, the pearl sac is enabled to uniformly secrete nacre by controlling the frequency and strength of infrasound, 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 pearl mussel nacre secretion, increasing the perfect circle ratio of pearls, 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 for...
