| Abstract: | At present, for soil agrochemical analysis experiments, more and more researchers have begun to invest in related researches. This article mainly focuses on the determination of soil organic matter potassium dichromate volumetric analysis method, through traditional oil baths and improved boiling water baths. Two heating methods, compare and analyze the experimental data, master the advantages and disadvantages of the two methods and the appropriate method selected in the research project research, through long-term experimental research, combined with the nature of the local soil to draw conclusions, hope that the related scientific research work will go smoothly Make a contribution to progress. |
