近年鳖的人工养殖发展很快,而如何提高鳖卵的人工孵化率则是广大养鳖专业户遇到的难题。要搞好鳖的人工孵化,提高鳖卵的孵化率,在孵化过程中,务必做到“三控一防”。一、控温鳖卵孵化的适宜温度是22—37 ℃,最适温度为28—35℃。38℃为临界高温,超过38℃会导致胚胎全部死亡,临界低温为22℃,低于22℃胚胎发育停止。孵化期间温度控制在30—35℃效果最好。另外孵化需要的天数与温度的高低有关,孵化积温
In recent years, artificial breeding of turtles has developed rapidly, and how to improve artificial hatching rate of turtle eggs is the problem encountered by the majority of turtles. To do a good job turtle artificial hatching, raising the hatching rate of turtle eggs in the incubation process, be sure to achieve “three control and one defense.” First, the temperature control turtle egg hatching suitable temperature is 22-37 ℃, the optimum temperature is 28-35 ℃. 38 ℃ is the critical high temperature, more than 38 ℃ will cause all the embryos to die, the critical low temperature is 22 ℃, less than 22 ℃ embryo development stops. Temperature control during incubation at 30-35 ° C works best. In addition, the number of days required for hatching and the temperature level, hatching accumulated temperature
