农田害鼠药物防制策略的探讨

大地回春,农田害鼠仍处于贫食阶段,并开始进入第一个繁殖高峰期。春季用抗凝血慢性杀鼠剂开展大面积灭鼠活动,不仅灭鼠、保苗效果好,且可压低农田害鼠的发生基数,争得全年药物灭鼠的主动权。夏秋季节,对鼠密度高的即将成熟的农作物田中,用急性杀鼠剂进行局部防治,可迅速扑灭鼠害,一般不必开展大规模的农田灭鼠活动。

Studies on the strategy of farm rodents control with rodenticides

It is very important that the farm rodents were controlled in early spring with anticoagulant rodenticides, because in this time, foods in field were poor, and rodents were in the first reproduction peak, so this control could protect seedling and reduce the amout of farm rodents.While in summer and autumn, a large scale control was not nessary in field, but the treatments with acute rodenticides still were taken if the density was high in harvesting field.
