土壤有机质是研究土壤肥力的一个重要测定项目,测定的方法很多,但目前国内一般以应用丘林的容量法为多。该法中的消化步骤是用油浴,具有较迅速、准确和易于掌握的优点,而且在无电源的地方也能使用。但其不足之处是在170—190℃高温下,油会气化造成空气某种程度的污染,同时消化过的待测液需要转移容器,易导致操作上的
Soil organic matter is an important measure to study soil fertility. There are many methods for determination of soil fertility, but at present, the volume method of applying Qulin is generally used in China. The digestion step of this method is an oil bath, which has the advantage of being quick, accurate and easy to grasp, and can be used where there is no power supply. However, the downside is that at a high temperature of 170-190 ° C, the oil will be gasified to some degree to pollute the air, and the digested liquid to be measured needs to be transferred to the container to easily cause the operation
