四、中国林蛙性别控制 　　中国林蛙的经济价值主要体现在雌性的输卵管上，因此在生产中如何提高雌性个体的比例就显得非常重要。自然条件下南方春季繁殖期水温相对比较高，繁殖期水温偏高导致后代雄性个体比例偏高。因此在南方进行中国林蛙养殖雌性诱变技术就显得更加重要，雌 Four, China Rana gender control China’s economic value of Rana mainly in the female fallopian tubes, so in the production of how to improve the proportion of female individuals is very important. Under natural conditions, the water temperature in the spring breeding season is relatively high, and the high water temperature in the breeding season leads to a high proportion of offspring male individuals. Therefore, in the South for Chinese female Rana Breeding mutagenesis technology is even more important, female
