我们在养鳖生产实践中经摸索并掌握了提高受精鳖卵的孵化率与稚鳖暂养成活率两项技术。现概述如下:1 室内恒温鳖卵孵化技术 受精鳖卵孵化的三个要素是,温度、孵化用沙的湿度,及通气状况,其中温度最为关键。温度恒定在30±2℃,湿度保持在80—85％,同时有良好的通气状况,从而提高受精卵的孵化率,缩短孵化时间。1.1 鳖卵孵化前的准备工作1.1.1 孵化室。面积10—15m~2为宜,坐北朝南,室内用砖砌成面积为1—1.5m~2的水泥池,供鳖卵孵化及后期稚鳖暂养用。池壁砌成“T”型压口,要求不漏水及保湿性能好。
We practice in raising turtle by groping and mastered the raising of fertilized turtle egg hatching rate and juvenile turtle survival rate of two technologies. Now summarized as follows: 1 indoor temperature turtle egg hatching technology fertilized turtle egg hatching three elements of the temperature, humidity and hatch sand, and ventilation, in which the temperature is the most critical. Constant temperature at 30 ± 2 ℃, humidity maintained at 80-85%, while good aeration, thereby increasing the fertilized egg hatching rate and shorten the incubation time. 1.1 Preparation of turtle eggs before hatching 1.1.1 hatching room. Area of 10-15m ~ 2 is appropriate, sit north facing south, indoor brick with an area of 1-1.5m ~ 2 cement pool for the turtle egg hatching and the later use of juvenile turtles. Pool wall puzzle “T” -type pressure mouth, requiring good water and moisturizing performance.
