摘    要:采用野外采样及室内分析方法,对沈阳市郊区蔬菜保护地与露地土壤中DTPA—Fe、Mn、Cu、Zn含量状况进行对比研究。结果表明,蔬菜保护地土壤中的DTPA—Fe、Cu、Zn含量明显高于露地土壤,DTPA-Mn含量则明显低于露地土壤。部分保护地土壤已达到对蔬菜生产造成不同程度Cu、Zn污染的状况。导致Fe、Cu、Zn含量升高和Mn含量降低的主要原因是大量有机肥料的投入改变了元素的含量状况,保护地土壤特殊的水、肥、气、热和生物因子影响了元素各形态间的转化。农药的大量施用也导致了蔬菜保护地土壤中Cu、Zn的富集。

关 键 词:蔬菜  保护地土壤  DTPA浸提          含量  土壤环境

Abstract:A comparative study on soil DTPA- extractable Fe, Mn, Cu and Zn contents in both vegetable greenhouse and cultivated soils was conducted in Shenyang suburbs, China, in order to explore the changes of micronutrients in soils under greenhouse vegetable cultivation. The results showed that DTPA- extractable Fe, Cu and Zn contents in greenhouse soils were higher than that in cultivated soils, while DTPA- extractable Mn content in greenhouse soils were generally lower than that in cultivated soils. Part of the greenhouse soils has reached the Cu and Zn pollution limit to vegetable production. Main reasons for Fe, Cu, and Zn increase and Mn decrease were attributed to the changes of element contents by high input of manure into soils, and the elemental forms are changed by the factors of moisture, fertility, atmosphere, temperature and biomass activity in greenhouse soils, while a lot of application of pesticide may also result in the increase of Cu and Zn contents in the greenhouse soils.
Keywords:soil  iron  manganese  copper  zinc  greenhouse  vegetables
