燃煤烟气脱硫副产物在酸性土壤的农业资源化利用

通过盆栽试验,研究了在酸性土壤上施燃煤烟气脱硫副产物对萝卜的影响及其对环境影响的初步评价.结果显示:(1)在两个不同土类、及同一土类不同母质的两种土壤上,萝卜适量施用脱硫副产物均可获得不同程度的增产和提高品质的效果.(2)在酸性土壤上施用供试物获得正效应是由于其富含红壤土类中普遍缺的有效性钙、硫、硼、钼、硅等作物营养元素;并能有效改善土壤的理化性能.(3)供试物中的重金属含量均没有超过国家的限量标准,故适量施用后,当造作物植株中检出的重金属均低于国家限量标准.

Agriculture resource Use Study of Desulphurization Byproducts of burn coal smoke with Acid Soils

The effects of applying desulphurization byproducts on radish growth in pot-experiment with acid soil were studied. It was showed that (1) applying desulphurization products to red soil derived from different parent material was effective in promoting the growth and improving the quality of radish; (2) The reason for positive effects could be that the desulphurization products are rich in Ca, S, B, Si, Mo e.t.c.Which are just lack generally in red soils. By applying desulphurization products properly, the physical and chemical property of soils was also effectively improved; (3) The content of heavy metal such as Pb, Cd, Cr, As, Se, Ni, Cu e.t.c. in desulphurization products was below the national set limit, thus applying desulphurization products properly to the soil, the content of heavy metal in the first season crop was below the set limit for nuisanceless food.
