摘要
本文通过对在镉污染的碱性土壤上所种植的蔬菜品种进行筛选，确立了以富集系数来判断不同的蔬菜品种对镉的富集的能力，从而选择那些在镉污染土壤上富集能力低的菜种，以减少镉进行食物链的量，对镉污染区域的生产具有实际的指导意义。
This article expounds to select plantable vegetable species on the alkaline soil polluted by cadmium and establishs accurate capacities of the different vegetable species by the method of accumulation coefficient.The seleetion of those species of low accumulative ability will reduce the quantity of cadmium within the food chain. The result can be used for practice of vegetable plantation in the area of cadmium pollution.
