| 摘 要： | 本文主要研究蔬菜大棚土壤中微量元素含量随棚龄(利用年限)的变化情况。结果表明:除Mo外,在0～40cm内不同深度处微量元素的含量差异很小;露天大田改为蔬菜大棚后第1年,微量元素含量一般显著降低,然后显著升高,5年后达到一个相对稳定的阶段;除Mo之外,微量元素含量之间均或多或少地呈现出一定的线性相关;大量施用家禽粪便和复合肥可能是蔬菜大棚土壤中微量元素含量增加的主要来源,但尚未引起土壤污染;土壤缺Mo严重,在施肥中应予适当的考虑。 |

| Abstract: | This paper was focused on changes in contents of trace elements in greenhouse soils under vegetable cultivation for 0 (CK), 1, 5, 8 and 11 years. The results showed that: Except Mo, there were little differences observed in Co, Cu, Fe, Mn, Ni and Zn contents from depth to depth within 0-40 cm; trace element contents decreased significantly in the first year after the field was turned into greenhouse for vegetable cultivation, but they increased significantly afterwards and reached a relative balance after five years; certain positive linear correlations were somewhat found among Co, Cu, Fe, Mn, Ni and Zn contents; large amounts of poultry dung and compound fertilizer were possibly the main sources for the increase in trace element contents in these soil, no soil pollution happened but attention should be paid to the severe deficiency of Mo in the soil |
