    摘要:

    对山东省海阳地区150个不同种植年限的番茄大棚土壤重金属元素的分布特征进行了调查研究。结果表明, 该地区番茄大棚土壤Fe、Zn、Cu、Mn含量平均值为18 874、80.1、27.7、467.5 mg/kg,变异系数26.7% ~ 39.2%,具有一定的空间变异性。该地区番茄大棚土壤Cu和Zn元素含量在种植年限为1 ~ 10年间逐年增加,而在种植年限11 ~ 17年间呈降低的趋势,番茄大棚土壤Cu和Zn元素含量随种植年限变化的规律与大棚土壤施肥量以及土壤pH的变化有关;随着蔬菜温室使用年限的增加,土壤Mn含量有逐年降低的趋势,Fe元素含量变化趋势不明显。

    Abstract:

    The distribution of soil heavy metal elements in 150 vegetable greenhouses under different utilization ages were investigated in Haiyang of Shandong Province, China. The results showed that the average contents of soil Fe, Zn, Cu and Mn were 18 874, 80.1, 27.7 and 467.5 mg/kg, respectively. The coefficients of variation was about 26.7% - 39.2%, which have some spatial variability. The contents of Cu and Zn in greenhouse soils increased at the first 10 years and then declined at the last 7 years. These variations were related with fertilization and soil pH. The content of Mn in greenhouse soils was decreased with the utilization years continued. The change of Fe content was not obvious.
