汾西县扁桃干果园社鼠肥满度的季节性变化研究

摘要

Rat traps and cages were deployed to catch social mice in the almond dried fruit garden in Fenxi County throughout the year. The weight and body length of niviventer collected every month were measured, and the fatness data were calculated one by one, and the fatness of each month was counted. The results showed that the fatness of almond forest community rats showed a single peak seasonal change, the highest in October, declined rapidly from November to December, declined slowly from January to March, the lowest in March, then increased slowly from April to July, and rose rapidly from August to September to the highest in October.%在汾西县境内扁桃干果园林地全年布署捕鼠夹和捕鼠笼捕捉社鼠, 将各月采集到的社鼠测量体重与体长, 逐只计算肥满度数据, 统计各月肥满度.调查结果表明:扁桃林社鼠肥满度呈现单峰型季节性变化, 全年肥满度10月最高, 11月—12月社鼠肥满度快速下降, 次年1月—3月缓慢下降, 3月肥满度全年最低, 随后4月—7月社鼠肥满度平缓增加, 8月—9月快速上升至10月的全年最高峰.
