文章主要从机肥料氮、磷、钾的含量测定方面出发,针对于普通复混肥料厂在有机肥料的测定中出现测氮的时间过长,没有购置分光光度计和火焰光度计等问题进行阐述。从而采取有效的方法对有机肥料的化学测定,以有利于提高各种化学物的分析水平。 In this paper, the content of nitrogen, phosphorus and potassium in fertilizer is mainly measured from the point of view of the content of nitrogen, phosphorus and potassium in organic fertilizers. In view of the fact that the time for measuring nitrogen in organic fertilizers is too long for common compound fertilizers, there are no problems such as purchase of spectrophotometer and flame photometer . In order to take an effective approach to the chemical determination of organic fertilizers, in order to help improve the level of analysis of various chemicals.
