农用土壤肥料养分测定仪研制

The Development of Instrument for Analysing Soil and Fertilizer Nutrient in Countryside

利用现代电子技术，采用液晶显示器、集成电路技术研制了一种低功耗、交直流两用的土壤肥料养分测定仪。与主机配套的有相应的测定土壤和肥料养分的化学试剂和器皿，仪器和配制的试剂构成了在农村测定土壤肥料的最小系统。实践证明：使用该测定仪能快速、可靠地测定出土壤、肥料中的养分含量，为在农村推广测土配方施肥和在基层鉴别化肥真假奠定了坚实的物质基础。

Using of modern electronic technique, adopting liquid crystal display and integrated circuit, we developed a new instrument for analysing of soil and fertilizer nutrient. It is of low power and can use not only Ac but also Dc.The minisystem for examination soil and fertilizer nutrient in countryside consists of main electronic instrument and chemical reagent for analysing of nutrient of soil and fertilizer. Practice demonstrate that the instrument can analyse soil and fertlizer nutrient quickly and reliably. It will lay strong material foundation for expanding applying fertilizer technology according to the soil nutrient and for appraising the quality of fertilizer in countryside.
