采集浙江省仙居县农田代表性土样3288个,测定了其中量和微量元素的含量。结果表明:土壤交换性Ca含量平均值为3.2 mg/kg,处于偏低水平;有效硫平均含量为30.16 mg/kg,处于较丰富水平;有效锰含量平均值为30.23 mg/kg,基本上处于较低水平;有效铜含量平均值为1.17 mg/kg,处于较丰富水平;水溶性硼平均含量为0.58 mg/kg,处于适量水平。土壤有效锰、有效铜和水溶性硼含量的变异系数较高,分别达71.9%、70.1%和60.3%。
A total of 3288 soil samples were collected from farmland in Xianju County, Zhejiang Province. The contents of trace and trace elements were determined. The results showed that the average content of soil exchangeable Ca was 3.2 mg / kg, which was at a low level. The average content of available sulfur was 30.16 mg / kg, which was at a relatively high level. The average content of available manganese was 30.23 mg / kg, Lower level; the average effective copper content was 1.17 mg / kg, at a relatively high level; the average content of soluble boron was 0.58 mg / kg, at a moderate level. The coefficients of variation of soil available manganese, available copper and water-soluble boron were higher, reaching 71.9%, 70.1% and 60.3% respectively.
