浙东红壤丘陵区农田土壤中量微量元素含量研究

         

摘要

The contents of medium and trace elements in 32S8 representative farmland soil samples collected from Xianju county of Zhejiang province were determined. The results showed that. The average exchangeable calcium content was 3.2 mg/kg, which was deficient. The average available sulphur content and the available copper content were 30. 16 mg/kg and 1. 17 mg/kg, respectively, which were abundant. The average available manganese content was 30.23 mg/kg, which was basically deficient. The average water -soluble boron content was 0.58 mg/kg, which was moderate. The variation coefficients of soil available manganese, available copper and water-soluble boron contents were higher, being 71.9% , 70.1% and 60.3%% , respectively.%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30.23mg/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%.
