1 秋冬季引龟苗的好处。因为龟常在新环境下,怕惊,捕食能力下降。龟苗从一个环境进入另外新的环境要通过1～2个月才慢慢适应。再说龟是变温性动物,进入秋冬季后,随着气候的逐渐下降,龟也逐渐生长缓慢。秋冬引种的好处就在于抓住此时龟生长缓慢的时机,即引种苗,让它进入新环境适应,开春后,气温上升,龟立即进入生长状态,不需要再适应新环境。一般情况下,秋冬引进的龟苗比春季引进的龟苗提前1～2个月进入生长期。 2 品种与质量直接影响经济效益。我国现有淡水龟类25种,引种前需对 1 autumn and winter turtle seedlings benefits. Because turtles often in the new environment, fear of panic, decreased predation ability. Turtle seedlings from one environment into another new environment to pass 1 to 2 months to adapt slowly. Besides turtles are warm-temperate animals, into the autumn and winter, with the gradual decline in climate, turtle gradually growing slowly. The benefits of autumn and winter introduction is to seize the opportunity tortoise growth is slow at this time, the introduction of seedlings, let it adapt to the new environment, after the spring, the temperature rise, turtle immediately into the growth state, do not need to adapt to the new environment. Under normal circumstances, the introduction of autumn and winter tortoises than the introduction of turtle in spring 1 to 2 months in advance into the growing season. 2 species and quality directly affect the economic benefits. There are 25 kinds of freshwater turtles in our country, which need to be correct before introduction
