摘要 人工驯养条件下,黄缘盒龟5月中下旬进入产卵期,6月中旬为产卵旺期,产卵期为46~54d,产卵时间集中在傍晚18:00~21:00.年产卵1次,年均产卵量2.5~2.6枚,卵的受精率为64.0%~64.6%.受精卵在常温与控温条件下的平均孵化期分别为76.7d、75.8d,孵化积温分别为47491.2~57741.1℃.h、45460.8~56088.0℃.h,最短孵化期为66d,最长孵化期为82d;常温孵化比控温孵化的平均孵化积温高1803.8℃.h,孵化率降低7.6%. Cistoclemmys flavomarginata begins to lay eggs in late May with peak period in the middle of June.The incubation time is 46~54 days with spawning time at 18:00~21:00.They lay eggs once a year and the average annual is 2.5~2.6 with the fertilization rate of 64.0~64.6%.The incubation time is 76.7 and 75.8 days of fertilized eggs under the normal temperature incubation and constant temperature incubation.The shortest incubation time is 66 days and the longest incubation time is 82 days.The accumulated hatching temperatures are 47 491.2~57 741.1 ℃·h and 45 460.8~56 088.0 ℃·h.The average accumulated hatching temperature of normal temperature incubation is 1 803.8 ℃·h more than constant temperature incubation.The hatching rate of normal temperature incubation is 7.6% lower than constant temperature incubation.
