Correlativity coefficient between the arsenic concentration of the soil extracted with 0.5 mol/L NaHCO_3 and the summation arsenic concentration of plant sample (pulp+branch+leaf+root) R=0.7545~* (n=6), reached to notable level.
当年生长抽发的植物样品(果肉+枝条+叶片+根系)砷合计量与土壤0.5mol／LNaHCO_3的浸提砷量的相关性系数R=0.7545~*(n=6)，达到显著正相关水平。 枝条砷含量与两层土壤(0～15cm、20～35cm)的NaHCO_3浸提合计量呈极显著正相关关系，R=0.7253~(**)(n=10)，叶片、根系砷含量与土壤的NaHCO_3浸提量之间相关性不显著。
