关于环境因素,如室内地面、住宅位置、存粮状况以及禽畜饲养等对鼠密度的影响,从直观和推理方面有过不少论述,甚至其中不乏符合实际的看法,但系统调查较少。为了弄清鼠密度波动的原因,采取针对性较强的解决办法,我们在崔庄和张庄进行了比较细致的调查。结果表明,有些传统看法并不合乎实际,按照这些看法采取措施,起不到控制鼠害的作用。
On the environmental factors, such as indoor ground, residential location, the status of food stocks and livestock breeding and other effects on rat density, from the visual and reasoning has been a lot of discussion, and even some of them are consistent with the actual view, but less systematic investigation. In order to find out the reason of the fluctuation of the density of the rats and to adopt a more targeted solution, we conducted a more detailed investigation in Cui Zhuang and Zhang Zhuang. The results show that some of the traditional view is not realistic, according to these views to take measures to control the role of rodent.
