A method of cultivating pearls

Abstract

The invention discloses a pearl cultivation method, and belongs to the aquatic product cultivation technical field; the method comprises the following steps: selecting a cultivation room to cultivate pearl oysters, wherein the cultivation room comprises a culture pond, a first purifying pond, a second purifying pond, and a water storage pond connected in sequence, and top surfaces of the four parts gradually descends in a stepped manner; utilizing a tide difference principle to realize water self-discharge self-irrigation in the pond; arranging a filtering net and a mesh screen to purify water body, thus saving energy, and reducing cultivation cost; arranging the bottom of a net cage to be a waveform surface so as to prevent pathogen infection, thus providing better growth environment for the pearl oysters; preparing nutrient solutions of different components to process cell small particles and pearl cores, thus improving core planting rate, and reducing core repelling phenomenon; applying different fertilizers to accelerate pearl oyster maturation in different stages, and promoting pearl quality in the same time.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a pearl cultivation method. Background technique [0002] As a colorful, dazzling, rare and precious decoration, pearls are deeply loved by the public, and can be refined into various necklaces, bracelets, ornaments and other decorations through processing.

Problems solved by technology

At present, more than 90% of the pearls on the market are artificially cultured pearls. my country is the earliest country to breed and has the largest culture output today. However, due to the backward culture technology and unscientific culture management in our country, the planning of the culture area is unreasonable, and the capacity is too high. Density breeding causes severe aging of the farm, and the wounds of pearl-growing mussels often fester and cause infection and even death. The formed pearls have a high rate of defects, a low rate of round beads, and a small number of high-quality pearls
