缩短养鳖周期的关键是控制水温。鳖的适宜生长水温是25~34℃,只要满足这一要求,可使500克左右的鳖养成商品鳖由原来的3~4年缩短为13~15个月。具体对策是: 1.合理放养亲鳖,强化培育,促其提早繁殖。每平方米放养亲鳖数量0.5~0.8只,重量0.6~0.9公斤。4月下旬,当亲鳖冬眠后开始活动时,将水位由原来的1.5米降至0.7米,以利提高水温。同时在水面敷设浮板,以增加鳖的体温和食欲。 2.控温控湿孵化鳖卵。要求温度32±2℃,相对湿度前期40天90%左右,后一周85%以下,沙的
The key to shortening the turtle cycle is to control the water temperature. The appropriate growth temperature of turtle is 25 ~ 34 ℃, as long as to meet this requirement, can make about 500 grams of soft-shelled turtle products from the original 3 to 4 years reduced to 13 to 15 months. Specific countermeasures are: 1. Provisional stocking soft-shelled turtle, strengthen nurturing and promote its early breeding. Per square meter stocking soft-shelled turtle 0.5 ~ 0.8, weight 0.6 ~ 0.9 kg. In late April, when the soft-shelled turtle began activities after hibernation, the water level was reduced from 1.5 meters to 0.7 meters in order to raise the water temperature. At the same time laying floating in the water, to increase the body temperature and appetite. Temperature controlled wet incubation turtle eggs. Requirements temperature 32 ± 2 ℃, relative humidity 40 days early 90% about 85% the following week, the sand
