摘要
黑龙江省带岭林区自60年代初,每3—4年发生一次棕背(鼠平)(Clethrionomys rufocanus)幼林鼠害。我们先后使用磷化锌、氟乙酰胺和敌鼠钠等药剂灭鼠,当时虽然压低了害鼠密度,但并没有起到长期防鼠的效果,害鼠数量有逐年上升的趋势。为此,我们提出林木鼠害的综合治理问题。一。
The Clethrionomys rufocans is an important rodent pest for young forest. This paper deals with the control measure during 1982-1987 in the Forest Bureau of Dailing. On the basis of habit that it's fond of eating tender oark, according to its regular dispersion, some branches from the residue of tending were thrown to substitute the food in young forest. Field experiment showed that this control measure was effective, and reduced the number of the voles, which protected the natural enemy, also saved the rodenticide cost.
