Gangue as one of the largest emissions of industrial solid wastes in China, not only takes up quantities of farmland, but also becomes the three sources of pollution harm of solid, liquid and gas, causes a series of ecological environment problems. Therefore we should strengthen the comprehensive utilization of gangue and let it become resources. The experiment was based on the analysis of its physical and chemical properties, through pot experiment, study on gangue together with two kinds of matrix that was loam and sand on the growth index and biomass of Chinese cabbage under different proportion. The results show that, while maintain the total weight of flowerpot, with the increase of gangue, the germination, plant height, root weight, fresh weight of Chinese cabbage has signiifcant effect on the index. When adding gangue in loam matrix is greater than 300 g, adding gangue in sand matrix is greater than 250 g, the growth and biomass index of Chinese cabbage decreases signiifcantly. In order to achieve the maximum comprehensive utilization of gangue, the proportion of loam and gangue should be 3:2, the proportion of sand and gangue should be 2:1, so that the gangue can achieve its maximum utilization.
