Embodiment 1

[0013] Collect fertilized eggs during the egg-laying season (May to July) of the third-line box turtle, and lay a 5cm hatching substrate (50% vermiculite + 25% river sand + 25% clay particles) in a plastic incubator with a water content of 8 ~ 25%; fertilized eggs are placed on the hatching substrate with the animal pole facing upwards, the distance between fertilized eggs is kept at about 1.2cm, and it is covered with an incubation substrate with a thickness greater than or equal to 1.5cm and the same humidity, and the moisture content of the substrate is about 8%; the hatching The box is placed in an incubator with temperature control and humidity control. The relative humidity of the incubator is kept at about 65%, and the temperature is controlled at around 30.5°C but not higher than 30.5°C.

[0014] When the embryo develops to a certain stage (temperature-sensitive period), adjust the temperature of the hatching room to 26°C at a rate of 2°C / day, adjust the air humidity to...

Embodiment 2

[0018] Collect fertilized eggs during the egg-laying season (May to July) of the third-line box turtle, and lay a 5cm hatching substrate (50% vermiculite + 25% river sand + 25% clay particles) in a plastic incubator with a water content of 8 ~25%; fertilized eggs are placed on the hatching substrate with the animal pole upwards, the distance between fertilized eggs is kept at about 1.2cm, and the hatching substrate with the same humidity of 1.5cm or more is covered on it; the incubator is placed in a temperature-controlled, In the humidity-controlled hatching room, the temperature of the whole hatching process is controlled at 25-26°C. The relative humidity of the hatching room is kept at about 65% in the early stage of hatching, adjusted to 80%-85% in the middle of hatching, and over 90% in the late hatching period. The water content of the matrix was controlled at 8% in the early stage of incubation, 15% in the middle stage of incubation, and adjusted to 25% in the late stage...

Embodiment 3

[0022] Collect fertilized eggs during the egg-laying season (May to July) of the third-line box turtle, and lay a 5cm hatching substrate (50% vermiculite + 25% river sand + 25% clay particles) in a plastic incubator with a water content of 8 % to 25%; the fertilized eggs are placed on the incubation substrate with the animal pole up, and the distance between the fertilized eggs is kept at about 1.2cm, and it is covered with an incubation substrate with a thickness greater than or equal to 1.5cm and the same humidity; place the incubator in a temperature-controlled , Humidity-controlled hatching room, the temperature of the whole hatching process is controlled at 30.5°C, the relative humidity of the hatching room is kept at about 65% in the early stage of hatching, adjusted to 80%-85% in the middle of hatching, and over 90% in the late hatching period, and the hatching matrix The water content of the fish is controlled at 8% in the early stage of incubation, maintained at 15% in...

Abstract

The invention relates to a male young cyclemys trifasciata hatching method capable of obtaining high hatchability, and relates to cyclemys trifasciatas. In the reproduction season of the cyclemys trifasciatas, a first layer of hatching matrix is laid at the bottom of a hatching box, and fertilized eggs are horizontally placed on the first layer of hatching matrix with the animal poles upward and then covered with a second layer of hatching matrix; the hatching box is placed on a shelf in a hatching room, the temperature in the hatching room is controlled to be at 26 DEG C-30.5 DEG C, the relative humidity is controlled to be 65-90%, and the hatching temperature is kept until the young cyclemys trifasciatas come out of shells. The eggs are hatched at high temperature except a temperature sensitive period, the indoor temperature and the humidity of the hatching media are adjusted correspondingly according to different growth periods, the hatching period can be shortened greatly, and the occurrence rate of mildewed eggs is reduced, so that hatchability of young water turtles is improved, the hatching period is shortened by about 25 days, and the hatchability is improved to more than 95%; the eggs are hatched in a suitable temperature range, and the male young cyclemys trifasciatas which are health and obvious in male characteristic can be hatched within about 85 days.

Description

technical field [0001] The invention relates to a three-line box turtle, in particular to a method for hatching three-line box turtle male seedlings capable of obtaining a high hatching rate. Background technique [0002] The three-lined box turtle (Cuora trifasciata) belongs to the genus Cuora trifasciata in classification, and is mainly distributed in Guangdong, Guangxi, Hainan, Fujian, Hunan, Hong Kong, Macau, Taiwan, Vietnam, Laos and other Southeast Asian regions. distributed. The three-lined box turtle is a temperature-sex-determined animal. Its sex depends on the hatching temperature during a certain period (temperature-sensitive period) during the hatching process. During this high temperature hatching, female hatchlings will be produced, and vice versa, male hatchlings will be produced. Due to the greenhouse effect, more than 99.9% of the offspring of the three-lined box turtle hatched under natural conditions are females. Therefore, it is extremely important to ca...
