摘要: 粉煤灰和滤泥以1:1(w/w)比例混合并添加少量化肥配制成混合物,通过盆栽试验研究该混合物农用对土壤生物化学性质、萝卜产量和品质的影响以及重金属在土壤和萝卜中的富集状况.结果表明,该混合物中Cd、Pb、Cr、As和Hg含量均明显低于国家农用粉煤灰中污染物控制标准;施用一定数量的该混合物未见导致重金属在土壤和萝卜中的明显富集作用,重金属污染指数均<1;土壤细菌数量显著增加;脲酶、磷酸酶和纤维素酶的活性增强;促进了萝卜的生长发育和代谢作用,萝卜的生物产量、经济产量、还原糖和维生素C的含量均明显提高.因此,适量施用该混合物未见导致重金属对土壤和萝卜的明显污染,且具有较明显的改土培肥、增产和提高萝卜品质的效果.

Abstract: Based on pot culture experiment,the effect of fly ash filtered mud mixture on soil biochemical properties,radish yield, its quality,and heavy metal accumulation in both soil, radish was examined.The mixture was made by mixing fly ash, filtered mud in proportion 1:1(w/w), adding small amount of inorganic fertilizer.Its Cd,Pb,Cr,As, Hg contents were much lower than those requested by state control criteria.After applying this mixture in a definite amount,no significant accumulation of heavy metals was found in both soil, radish,the pollution index of heavy metals was <1,the quantities of soil bacteria increased notably,and the activities of soil urease,phosphates, cellu2 losase also raised significantly.The application of the mixture promoted radish growth, its development, metabolism.The reducing sugar, vitamin C in radish also increased markedly.The results indicated that the use of adequate amounts of the mixture did not cause any obvious heavy metal pollution in both soil, radish,but could im2prove soil fertility,and raise radish yield, its quality remarkably.
