研究了一种快速测定土壤有机磷的方法,(土样用0.3MNaOH 液浸提后用超声波处理3分钟),并与原有的灰化法与浸提法进行比较。结果表明,快速法测得的结果与测定步骤冗长的浸提法相似,测定高度风化的土壤时该法比灰化法更加准确。
A rapid method for the determination of soil organic phosphorus was studied. (Soil samples were treated with 0.3M NaOH for 3 minutes and then sonicated for 3 minutes). The results were compared with the conventional ashing and extraction methods. The results show that the fast method is similar to the tedious one in the determination of highly weathered soils. This method is more accurate than the ashing method in the determination of highly weathered soils.
