洞庭湖区农业生产格局及措施对农田害鼠种群数量的影响研究

Influence of agricultural productive structure and countermeasures on the rodent population density of the farmland in Dongting Lake area

  • 摘要: 研究洞庭湖区农业生产格局及措施对农田害鼠种群数量的影响结果表明,水稻田鼠密度高于棉花地,初冬稻茬地鼠密度高于油菜地,开春后油菜地鼠密度高于稻茬地;无酚棉田鼠密度高于有酚棉田,田埂硬化农田鼠密度显著低于未硬化田埂农田。早稻播种、双抢和晚稻收割等全局性农事活动可改变生境导致鼠迁移扩散而对农田害鼠种群数量变化产生一定影响,且因地区和鼠种而异,但受农田害鼠自身繁殖特性制约而对总鼠密度的影响呈不明显差异。

     

    Abstract: The influence of agricultural productive structure and countermeasures on the rod ent population density of the farmlands in Dongting Lake area is studied.The results show that the population density of rod ent in paddy field is higher than that in cotton land;and its population density in ha rvested paddy field is higher than that in rape land in the first month of winter,but the population density of rod ent in rape land is higher than that in harvested paddy field in the begin.ning of spring;the population density of rod ent in the non phenol cotton field is higher than that in the phend cottonfield,the po pulation density of rod ent in the field with hardened ridge is lower than that in the field with unhardened ridge.The agricultural productive activities,i.e.the early rice seeding,seeding and harvesting in time,the later rice har.vesting,may cause the migration of rodents owing to the change of the habitats,while the influence on rodent population density is restricted by it propagating characteristics,so the po pulation density of rodent is not affected markedly by themain agricultural productive activities in the farmland.
