2. Distinguish between the plant pole and the animal pole: the plant pole is pink, the animal pole is extremely white, and the upward direction is better. The side where the turtle comes out is the animal pole, so the plant pole is placed below and the animal pole is placed above.
3. Gently place the turtle eggs in the sand to keep a certain humidity, but not too wet: put the turtle eggs in the sand, and then spread 5 cm medium sand and 1-2 cm thick fine sand in turn. The fine sand is mainly used to keep the humidity and prevent the water from evaporating too quickly. Spread a towel on the fine sand, and it is better to spray water on the towel.
4. Pay attention to the incubation temperature: the temperature of the prepared sand is about 30℃. Below 25℃, embryo development is slow; At 38℃~40℃, the embryo will die within a few hours. In order to maintain the best temperature, the temperature is high in summer, so it is necessary to ventilate and cool down; When the temperature is low, close the doors and windows to keep warm.
5. The final shelling is the key step: 5-8 days later, the plant pole (opposite to the animal pole) turns pink; After 20~25 days, the plants are extremely red and black, and at this time, young turtles have formed; From 26 to 30 days, slightly black embryos can be seen in plants; After 33 days, the whole egg turned white, and the animal and plant poles could not be distinguished.
Extended data:
Turtle is an aquatic omnivore and likes to eat animal bait. Young turtles feed on aquatic insects, water worms, tadpoles and shrimps. Keep it in water.
Soft-shelled turtle is an amphibious animal, breathing with lungs, so there should be enough land beach around or in the center of the nail pond for land activities. Turtle is sensitive to the sound of the surrounding environment. As long as there is a slight movement around, turtle can quickly dive into the bottom mud, so the breeding environment must be kept quiet.
If soft-shelled turtles are often frightened, it is very unfavorable for their growth and reproduction. Turtle likes to stay in an environment with good water quality, so the owner must change the water frequently, about once every 2-3 days.
