The golden turtle generally does not mature until the gonads are over 7 years old, and matures well over 9 to 10 years. The mating period of the money turtle is mainly in the spring and autumn of each year, the male turtle is particularly active in the estrus period, the expression is excited, the mating process is carried out in the water, first the male turtle chases the female turtle, the head blocks the female turtle procession, after a period of flirtation, when the female turtle swims slowly, the male turtle will sneak up on the back of the female turtle with the forelimbs, swoop down on the back of the female turtle, the female turtle will not be able to bounce, after dozens of minutes of entanglement, the female turtle touches the scene, reaching the peak of the estrus period, at this time the male turtle will quickly insert the handover into the female turtle's cloaca to mate with it. Time can be up to a few minutes. Mating time is generally from 17 to 18 pm, mating on land or water. The golden turtle lays its eggs on land, and the spawning period is from May to August. Before spawning, the amount of food is reduced, which is obviously not very active, which is a harbinger of imminent labor.

When laying eggs, the golden turtle mostly crawls to a place far from the shore before dusk or dawn to a more hidden and loose soil (the moisture content of the soil is 5% to 20%), and the hind limbs alternately dig the soil into a burrow (generally the depth of the burrow is about 10 cm, the caliber is 8-12 cm), and then the eggs are laid in the burrow, and after laying the eggs, the soil is covered with the soil, and the soil is flattened with the abdominal nail before leaving. The golden turtle does not have the habit of guarding the nest and protecting the eggs; Another reproductive feature of it is that the maturation of the eggs is not synchronized. Therefore, the female turtle lays eggs once a year, 2 to 9 eggs each time.
When artificially breeding money turtles, before the mating period, first select the mature golden turtles, carefully raise, supply sufficient nutrients, especially should be fed more protein-rich feed, in order to facilitate the production of excellent germ cells of the money turtles; Secondly, during the mating period of the golden turtle, the male and female golden turtles that have matured and are physically fit are combined in a 1:1 ratio to allow them to mate naturally. During the spawning period of the golden turtle, attention should be paid to keeping the feeding pond quiet and the suitable humidity of the sandy soil on the open space outside the pool, so as to facilitate the smooth laying of eggs by the female golden turtle.
Collect the eggs after the golden turtle lays eggs, because the female turtle lays eggs at night, and every morning you can observe the circular footprints left by the female turtles at the spawning site, which can be marked to avoid direct sunlight, so it is most appropriate to collect eggs around 6 o'clock in the morning. In order to make the embryos of the eggs sound, the eggs can be collected once every three days, and the sand should be gently opened by hand when collecting eggs, and after egg collection, they should be gently placed in the temporary box and transferred to artificial incubation.
Fertilization reactions are visible from 24 hours to 72 hours postnatal, up to 8 days at the latest. At the beginning of the reaction, the white dots of the fertilization reaction are visible in the center of the turtle egg and slowly spread, forming a grayish-white halo. At this time, the fertilized eggs can be selected for incubation. The incubation temperature of turtle eggs is most suitable for 30 °C, the general incubation period is about 80 days, higher than 30 °C, the incubation period is shorter, lower than 30 °C, and the incubation period is longer. Through these scientific breeding techniques, a high reproduction rate is obtained and the economic benefits are improved.
