农村鼠种构成和鼠密度的消长，与不同环境条件有密切关系，调查表明，野外以黑线姬鼠为主要鼠种，村内褐家鼠是主要鼠种，其密度分别为：野外旱田２２．０％；水田为１９．６０％。村内新房户占２．２９％；旧房户占５．５７％。室内坚持长年布饵灭鼠户占１．００％；未布饵灭鼠户占４．３３％；粮食散放户占８．４０％；粮食封存户占２．２０％。村边户与村内户鼠密度为６．３６％和５．５４％。为科学灭鼠，防病保粮提供了可靠依据。
The growth and decline of rat population in rural areas and the density of rats are closely related to different environmental conditions. Survey shows that in the wild, Apodemus agrarius is the main mouse species, Rattus norvegicus is the main mouse species in the field, and its density is respectively: field dry field22. 0%; paddy field is 19.60%. 2.29% of new households in the village and 5.57% of old ones. Indoor long-term adherence to cloth bait rats accounted for 1.00%; bait off rodent households accounted for 4.33%; grain storage households accounted for 8.40%; grain storage accounts for 2.20%. Village households and village households with rat density of 6.36% and 5.54%. Science for rodent control, disease prevention and grain provide a reliable basis.
