对采自全国各地 2 0个土壤样品进行测定 .结果表明 ,树脂膜法测定的土壤微量元素值与DT PA法测定的土壤有效微量元素之间具有极显著的相关性 ,国产树脂膜的测定值与DTPA法测定值间的相关性稍优于进口树脂膜 .阴离子交换树脂膜法测定的土壤有效Mn与植物实际吸Mn量间的相关性好于DTPA法测定值与植物实际吸Mn量间的相关性 ,国产树脂膜法测定值与植物实际吸Mn量间的相关性稍好于进口树脂膜 ,指数相关性好于一次直线相关性 .离子交换树脂膜法可以用来测定原位土壤中的有效微量元素 ,国产树脂膜可以替代进口树脂膜 .
The soil samples collected from 20 soil samples were measured.The results showed that there was a significant correlation between soil trace element values measured by the resin membrane method and soil available trace elements measured by the DT PA method.The measured value of the domestic resin membrane And the correlation between DTPA method and the imported resin film was better than the imported resin film.The correlation between soil available Mn and the actual amount of Mn absorbed by the plant by anion exchange resin membrane method was better than that between the measured value of DTPA method and the actual amount of Mn Correlation, the measured value of the domestic resin membrane and the actual amount of Mn absorbed by the plant slightly better than the imported resin film, the index correlation is better than a linear correlation. Ion exchange resin membrane method can be used to determine the in situ soil Effective trace elements, domestic resin film can replace imported resin film.
