摘要
[目的]研究设施大棚农业对土壤肥力和土壤环境质量的影响.[方法]通过对设施蔬菜大棚的土壤和露天蔬菜种植地的土壤分别进行采样分析,测定其中的养分和重金属元素的含量,根据所测结果利用指数和法和污染指数法进行评价.[结果]设施大棚土壤中的养分元素含量,均高于露天农田,指数和法评价其肥力达到了一级或者二级水平;设施大棚土壤中的重金属元素Cu、Cr、Cd、Pb、Zn的含量均比露天种植地高,污染指数法评价表明,土壤均处于清洁水平.[结论]设施大棚农业提高了土壤的肥力,但是重金属在土壤中的积累作用明显.
[ Objective] To study the effect of agricultural greenhouse on soil ferti l ity and soil environmental quality. [ Method] The contents of nutrients and heavy metal elements were determined by sampling and analysis of the soils of vegetable greenhouses and open soils in open field. The indexes were evaluated by exponential method and pollution index method according to the measured results. [ Result] Nutrient con-tent of agricultural greenhouse was higher than that of open field. Soil fertility reach to first level or second level by exponential method evalua-ting. Contents of Cu, Cr, Cd, Pb and Zn in the greenhouse were higher than those of in the open field, and the fertility of the greenhouse was higher than that of the open field. The content was higher than that of open field, and soil was at the clean level by pollution index method e-valuating. [ Conclusion] Greenhouse agriculture increased the soil fertility, but the accumulation of heavy metals in the soil was obvious.
