摘要
介绍了ＹＮ型土壤肥料养分测定仪的结构及工作原理。利用集成电子技术设计的土壤肥料养分快速测定仪工作可靠、快速简便、重现性好、测试精度高。试验结果表明，速测的土壤中Ｎ，Ｐ，Ｋ的结果与常规测定呈极显著相关关系，其Ｎ，Ｐ，Ｋ的相关系数分别为０８８７０，０９８９７。
The paper gives a detailed introduction to the structure and working principle of YN type speediness soil and fertilizer nutrient measuring apparatus. Designed by making use of the technology of integrated circuit,the apparatus is of high perfornance price rate and high reliability According to the reports of Soil and Fertilizer Work Station of Shanxi Province, the apparatus can be widely used in the countryside and is provided with high amplitude foreground.
