近年来,农村养鳖(甲鱼)的人越来越多,但大都是模拟自然方式养殖,鳖从孵化出壳到养成商品鳖,一般需3～5年,效益不甚理想。如何缩短鳖的养殖周期?实践证明,应用以下新技术,可使养殖周期缩短为一年多时间。1.人工孵卵鳖卵在自然条件下孵化慢,孵化率极低,人工孵卵可加快孵化速度,且能使孵化率达90%以上。方法是:把直径为0.5毫米左右、含水量为7～10%的细砂子平铺在盛卵盒内(盛卵盒自制,大小根据需要掌握),厚
In recent years, there are more and more people raising turtles (turtle) in rural areas, but most of them are farming in simulated natural ways. The turtles usually hatch from hatching to raising turtle products for 3 to 5 years, and the benefits are not very satisfactory. How to shorten the breeding cycle of turtle? Practice has proved that the application of the following new technologies, can shorten the breeding cycle for more than a year. 1. Artificial hatching Soft-shelled turtle eggs hatch slowly under natural conditions, hatching rate is very low, artificial hatching can speed up the hatching rate, and can make the hatching rate of more than 90%. Method is: the diameter of about 0.5 mm, the water content of 7 to 10% of the fine sand tucked in the egg storage box (made of egg boxes, according to the need to master size), thick
