摘要
利用流动分析仪测定了烟田土壤中的全氮、全磷。结果表明,氮的RSD<2%,回收率97.7%～102.5%;磷的RSD<2%,回收率96.2%～104.7%。
Total nitrogen and total phosphorus in tobacco field soil were determined with a Skalar flow analyzer. The results showed that RSD and recovery were <2% and 97.7%-102.5% for total nitrogen, and <2% and (96.2%)-104.7% for total phosphorus, respectively.
