摘要
本实验对土壤用水浸提和ＫＣｌ浸提两种方法测定其活性酸和潜在酸，并用不同的液土比测定其ｐＨ值。其结果是：用不同的浸提液测定的土壤ｐＨ值差异极其显著。而不同的液土比之间测定的ｐＨ值虽有随着液土比的增大ｐＨ值增高的趋势，但差异不显著。
Water and KCl solution extraction and different ratioes of liquid/soil were used to detect the active and latent acidity in soils.The different extration liquid resulted obviously different soil pH. The soil pH rised with the increase in ratio between liquid and soil, but the difference in pH was not obvious.
