一般试验室大都采用丘林容量法测定土中有机质的含量大小,亦有用硫酸注射法进行快速的测定工作,虽然测定的方法稍有不同,但他们的计算方法是相同的.计算公式中有七个变数,如果按普通方法进行计算,不但费时,而且容易出错.随着社会主义建设的飞跃发展,土中有机质含量的测定工作大为增加. In most laboratories, the content of organic matter in the soil is determined by the Khulin Volumetric Method, and the rapid determination by the sulfuric acid injection method is also used. Although the methods for determination are slightly different, they are calculated in the same way. There are seven If variables are calculated according to ordinary methods, it will be time-consuming and error-prone.With the rapid development of socialist construction, the determination of organic matter in soils has greatly increased.
