摘要
在污染区和清洁区,对瘤坚大球蚧密度和其寄主国槐树体营养(总糖、可溶性蛋白质、氨基酸、VB2)研究发现:污染区蚧虫密度和寄主营养水平均高于清洁区。
This paper studies on the scale (Eulecanium gigantean (shinji)) density and its host nutrition (total carbohydrate,soluble proteins) in the polluted areas and clear areas. The results show that in polluted areas the scale density and its host plant's nutritional level were higher than that in the clear areas.
