摘要 目的 明确害鼠空间配置 ,为灭鼠提供科学依据。方法 采用夹夜法调查害鼠在农田的分布。结果 作物构成复杂的样区鼠密度最高 ;不同作物地害鼠构成比率各不相同。稻果、稻菜混合种植区害鼠分布与水稻生育期有密切关系。水稻生长中后期 ,稻田鼠密度显著高于果园和菜地 ;水稻收获后 ,果园和菜地鼠密度又显著高于稻田。在一个大样区内 ,不同作物、同作物不同生育期或杂草生长状况不同 ,鼠密度一般相差 1~ 4倍 ,最高相差 2 7.3倍。结论 害鼠空间分布极不平衡 ,凡为害鼠提供丰富食物、良好栖息地和隐蔽条件的环境鼠密度高 ,反之则低。只有充分利用害鼠空间分布规律 ,科学灭鼠 ,才能经济有效地控制鼠害。 Objective The distribution of farmland rodents were studied to provide theory foundation for rodent control in Guangdong province. Methods The rodent density of different environment was investigated using night trapping method. Results The density of farmland rodents was topmost in the intercrop region and the composing of rodents was different in various environment. In the regions that rice interplanted fruit tree or vegetable there was remarkable correlation between the distribution of rodents and rice growth stage. Rodent density in rice field was higher than in fruit or vegetable field in the second half period of rice growth, but it was the lowest after rice harvest. In a big sample site, due to the differences of crops, the development stage of the same crop and weeds condition, the rodent density varied from 1 to 4 folds with each other in usual, but the highest could reach 27.3 folds compared with the lowest. Conclusion The distribution of rodent was imbalance. On the circumstance that provided better foods and habitat, the rodent density was high. It was an effective method to control farmland rodents economically using rodenticide accurately known rat's primary habitat.
