对人工孵化的中华花龟幼龟进行了为期60个月的养殖,记录了幼龟生长和发育过程;对中华花龟两性形态特征和个体繁殖力进行了研究。结果表明,雌、雄龟性别形态的区别在于第二性征的出现,即雌性龟腹甲平坦,尾巴短小,肛孔距腹甲后缘近;雄性龟腹甲内凹,尾巴粗壮,肛孔距腹甲后缘远。雌、雄两性个体的生长存在明显差异,在前12个月,雌性生长稍快于雄性,表现为背甲长、背甲宽、体重较大,但两者间差距不太大;在后期中,雌性生长速度则快于雄性。至试验期结束时,雌性个体平均增重量为雄性个体的3.86倍。雌性个体生育力回归分析表明,中华花龟的产卵数量与背甲长和体重的回归关系显著,雌性通过增加个体大小(背甲长和体重)来提高个体生育力。
The hatching and breeding process of Chinese turtle hatchlings was conducted for 60 months. The growth and development of juvenile turtles were recorded. The morphological characteristics and individual fertility of Chinese turtles were studied. The results showed that the difference between female and male turtles was the appearance of the secondary sex, namely, the female tortoise shell was flat and the tail was short, and the anal hole was close to the posterior border of the plastron. The male turtle belly was concave, the tail was thick, Caesarean section away from the trailing edge. In the first 12 months, the female grows slightly faster than the male, which is characterized by a long carapin, a large carapace and a large body weight, but the difference between the two is not too big. In the later period , Female growth rate is faster than the male. By the end of the study period, the average weight gain of females was 3.86 times that of males. Regression analysis of individual fertility in females showed that there was a significant correlation between the number of spawning eggs and the length and weight of carapaces in females. Females increased their individual fertility by increasing individual size (carapace length and body weight).
