对广西沙田柚主产区果园21个0-30cm表层土壤样品和12个土壤剖面的36个土壤样品进行了有效铜及全铜含量测试分析。结果表明,沙田柚果园的表层土壤有效铜含量范围是0.18~23.93m g/kg,平均值为3.33m g/kg,高过广西耕地土壤有效铜的平均含量及柑桔园土壤有效铜的适量范围;土壤全铜含量在5.71~71.35m g/kg之间,平均值为29.36m g/kg;果园表层土壤有效铜含量主要受土壤pH和有机质含量影响;在土壤剖面中,土壤有效铜及全铜含量随土壤剖面层次的加深而减少。
Twenty-one soil samples from 0 to 30 cm in the orchard of the main producing areas of Shatian pomelo and 36 soil samples from 12 soil profiles were tested for their available copper and copper contents. The results showed that the available copper content of topsoil of Shatian pomelo orchard was 0.18 ~ 23.93mg / kg with the average value of 3.33mg / kg, which was higher than the average content of available copper in arable land in Guangxi and the available range of available copper in citrus orchard. The content of total copper in the soil was between 5.71-71.35mg / kg, with an average value of 29.36mg / kg. The available copper content in the surface soil of orchard was mainly affected by soil pH and organic matter content. In the soil profile, Soil profile deepened and reduced.
