对土壤肥料的分析研究,其中分析项目繁多,对每个项目的测定有很多方法,在一些书籍中也常常见到,我们的工作主要是根据目前农村仪器,药品的设备,尽量采用简单快速的操作方法,使土壤的改良确实有效。根据我们的初步经验,我们认为在目前条件下可以采用下列各个步骤和方法来对土壤肥料进行分析。一、土壤样品的采取方法这项工作非常重要,因为只有用同样的方法采取能代表该区土壤真实情况的样品来分析,才能获得正确的结果,若随便抓一把土壤或肥料便送至化验室要求分析,它的结果是毫无意义的。
Analysis of soil fertilizers, of which a wide range of analysis, the determination of each project has many ways, is also often seen in some books, our work is mainly based on the current rural equipment, pharmaceutical equipment, try to use simple and fast Method of operation, soil improvement is indeed effective. Based on our initial experience, we believe that under the current conditions, the following steps and methods can be used to analyze soil fertilizers. I. METHOD OF SOIL SAMPLING This work is very important because only by using the same method to analyze samples that represent the true condition of the soil in the area can we get the correct result. If we simply grab a soil or fertilizer and send it to the laboratory Room requires analysis, its result is pointless.
