The key to turtle breeding is to grasp the hatching of turtle eggs. No matter which hatching method is used, it is necessary to grasp the three factors of incubation temperature, humidity, and air permeability. According to the three-lined shell turtle, snapping turtle and yellow-shouldered turtle in recent years, The hatching test of eggs of different turtle species, such as the eagle turtle, can achieve a hatchability rate of 95-98% as long as the temperature, humidity, and air permeability are in the best condition.
First, the incubation temperature: turtle hatching temperature should be controlled at 28-35 °C, about 30 °C is the best. Can not be too high or too low, when the temperature is low, artificial heating can be used. There are electric heating, solar heating, stove heating and so on. If the temperature is too high, the window should be ventilated and cooled. In short, once the incubation temperature is set, the temperature difference cannot differ by 3°C before and after.
Second, the incubation humidity: turtle hatching humidity is generally more suitable for hatching sand moisture content of 7-8%. If the humidity is too high, the turtle eggs can easily get rid of gas and die. If the humidity is too low, the turtle eggs will easily evaporate and the eggs will die. A more practical test method is: hand-sanding into a group, spread the hand after the group is dispersed, indicating moderate humidity. The hatching sand of the three-lined shell turtle and eagle turtle should be mixed with soil as a ratio of 6:4. In addition, spray water to spray 1-2 times a day during the incubation process.
Third, hatching air state: egg hatching air permeability is the hatching sand thickness should be moderate, should be selected from the middle of the river fine sand, clean before use, three-lined shell turtle hatching soil with loess as well, and with sand full Stir evenly, during the incubation period, spray water 10 minutes after each day, loosen the sand layer by hand. This will not only prevent the sand plate from closing and prevent moisture from evaporating. However, when the sand layer is shaken, it must not vibrate the eggs below, so as not to affect hatching. effect. In particular, the hatching sand used for snapping turtles, yellow-throated turtles, and tortoises all use medium sand and does not need to be mixed with loess, so as not to affect the shelling rate. In addition, it is also important to keep the hatchery box sheltered from wind, shade and quietness.
