【摘要】 中华鳖卵的壳、蛋白和卵黄重量比为３∶９∶１３。卵重在孵化过程中减轻６．０４％～９．５１％，并与孵化率、稚鳖出壳时体重成正相关。排卵密度也是影响大规模孵化的重要因素。胚胎在孵化过程中死亡曲线约呈双峰型。更多还原

【Abstract】 The weight proportion of Trionyx sinensis ’s egg shell, albumen and yolk is 3:9: 13. The weight of egg is decreased 6.04% ~ 9 .51 % during incubation, and is positive correlation to proportion of hatch and weight of childish Trionyx sinensis.
