碳酸盐土壤吸收容量的测定,是土壤调查中了解土壤肥力、土壤分类、土壤改良不可缺少的分析项目。因此,关于这方面的测定,前人曾作了许多研究,拟定了不少方法。但在这些方法中,大多手续繁 琐,费时颇多,不能在短时间内得到满意的结果。一般认为较可靠的(指碳酸盐土壤)鲍布考一阿斯克纳兹法(1),也需多次代换,费时五六天后才能得到正确 Carbonate soil absorption capacity of the determination of the soil survey to understand soil fertility, soil classification, soil improvement indispensable analysis of the project. Therefore, on this aspect of the measurement, many studies have been made and many methods have been drafted. However, most of these methods are complicated and time-consuming, and can not be satisfactorily achieved in a short period of time. It is generally considered more reliable (referring to the carbonate soil) abacus Knob test method (1), but also need to be replaced several times, took five or six days to get the correct
