鼠害是三七主产区的一大隐患。从三七播种至收获,老鼠不仅危害三七的根、茎、果实,还在地里串洞拱土,破坏墒面,造成缺苗,严重影响三七的正常生长。各地虽然采用了许多方法防治,但收效甚微。1988～1990年,我们针对老鼠的活动规律,在不同的季节采用不同的方法防治鼠害,取得较好的效果,现简介如下。 1.早春,在三七播种至出苗阶段,主要清除七园内及四周的杂草或堆放物,减少老鼠栖息场所,同时采用地膜覆盖栽培形成屏障。
Rodents are a major hidden danger in the main producing area of Panax notoginseng. From Panax sowing to harvest, not only endanger the roots of Panax notoginseng, stems and fruits, but also in the field of string arch soil, destroy moisture surface, resulting in lack of seedlings, a serious impact on the normal growth of Panax notoginseng. Although many methods have been adopted in various places, they have had little effect. From 1988 to 1990, we used different methods to control rodent pests in different seasons to achieve better results. The brief introduction is as follows. 1. Early spring, sowing to the emergence of the stage of Panax notoginseng, mainly to remove seven orchards and surrounding weeds or stacked objects to reduce the habitat of rats, while using film mulching to form a barrier.
