对咸阳市三原、泾阳、兴平、秦都等地蔬菜主产区不同利用年限的蔬菜日光温室24个样点的土壤有效微量元素变化特征进行调查研究。结果表明：土壤有效B、Cu、Zn、Mn、Fe的含量范围依次为0．11～0．56、1．50～6．94、2．90～11．79、13．49～30．93、8．53～44．00 mg/kg，变异系数为27％～47％。随温室利用年限的增加，土壤有效Zn、B含量总体上呈增加趋势，土壤有效Fe、Mn、Cu含量与棚龄呈负相关；土壤有效Cu、Zn、Mn、Fe的含量较高， Cu、Zn超量风险较高，有效B含量较低。蔬菜温室土壤母质、pH、Eh、施肥习惯、管理水平等的差异，是导致土壤有效微量元素变异较大的主要因素。

The variation characteristics of available microelements in 24 vegetable solar greenhouse soil samples with different utilization years were investigated in Sanyuan , Jingyang , Xingping , Qindu of Xianyang vegetable producing areas .The results showed that the contents of soil available B , Cu, Zn, Mn, Fe were 0.11~0.56, 1.50~6.94, 2.90~11.79, 13.49~30.93, 8.53~44.00 mg/kg respectively with the varia-tion coefficients of 27%~47%.With the increase of utilization years of greenhouse , the soil available Zn , B showed an increasing trend on the whole ,While the contents of soil available Fe , Mn, Cu were negatively cor-related with the utilization years of greenhouse .The contents of soil available Cu , Zn, Mn, Fe were higher. The excess risk of soil Cu , Zn was relatively higher .The available B content was lower .The differences of vegetable greenhouse soil parent material , pH, Eh, fertilizing habits and management levels were main factors resulting in large variations of soil available microelements .
