1.概述自1961年农林水产省开展地力保全对策诊断工作以来,土壤诊断有很大发展,有关部门也更加认识到该项工作的重要性。随着比色计和火焰光度计组合仪器的发展,原子吸收光谱仪的普及等,土壤养分的快速测定法进展迅速。但是,盐基交换量和交换性盐基的测定,仍然以提取操作费时费力的Schollenberger方法为主,人们希望能快速测定。为此,我们利用提取土壤养分的装置组合成,搅拌提取法,使盐基交换量和交换
1. Overview Since 1961, MAHDI has made great efforts in the diagnosis of geo-preservation measures and the departments concerned have also realized the importance of this work. With the development of colorimeter and flame photometer instrumentation, the popularity of atomic absorption spectroscopy, rapid determination of soil nutrients rapid progress. However, the determination of base-exchange and exchangeable base is still dominated by the time-consuming Schollenberger method of extraction, which is expected to be rapid. To this end, we use the device to extract soil nutrients into a combination of extraction method, the exchange of salt-based and exchange
