土壤pH平均值计算模型探讨

DISCUSSION ON CALCULATING MODEL OF SOIL PH AVERAGE VALUE

土壤pH平均值计算模型在土壤学界暂未达成共识。这里基于水化学酸碱中和平衡理论和土壤pH值测试原理,针对以往pH平均值计算模型原理及其存在的不足,建立了土壤pH平均值计算新模型。对比应用发现,新模型计算结果准确并易于掌握。

So far,no certain calculating model of soil pH average value is accepted by the pedologists.Based on the theory of ionization equilibrium of aqueous solution and testing for soil pH value,a new calculating model for pH average value is developed on the form of the flawed calculating model of soil pH average value.Compare with the results from different models,the new calculating model is very exact and easy to grasp.
