摘　　要：[目的]探索中华鳖的适宜生态环境条件。[方法]通过正交试验,研究不同温度、相对湿度和孵化介质对中华鳖孵化率的影响。[结果]中华鳖胚胎发育的最优条件为:温度30℃,相对湿度为75%～85%,孵化介质粗砂、中砂、细砂的比例为1∶4∶1。此条件下,中华鳖的孵化率最高,为98.0%。根据其胚胎发育情况,将中华鳖的胚胎发育过程分为9期。[结论]该研究为中华鳖的人工孵化提供了理论基础与借鉴依据。[ Objective] The research aimed to discuss the suitable ecological environment conditions of Trionyx sinensis. L MethodJ Usmg orthogonal test,the effects of different temperature, relative humidity and hatching medium on the hatching rate of T. sinensis were studied. [ Re- suit] The optimum conditions for the embryonic development of T. sinensis were as follows：temperature of 30 ℃ ,relative humidity of 75% - 85%, using the hatching medium with the ratio of coarse sand：medium sand：fine sand of 1： 4： 1. Under these conditions,the hatching rate of T. sinensis was highest, being 98.0%. According to the embryonic development of T. S＇inensis,its embryonic development process was divided into 9 stages. [ Conclusion] The research provided theoretical basis and reference for the artificial hatching of T. sinensis.
