摘要
在分析土壤快速测定仪设计技术基础上从低成本快速土壤养分测试的目标出发 ,提出了研制土壤养分速测仪结构和原理 ,介绍了YN型土壤养分测定仪设计思路及实现方法。实测数据表明YN型土壤肥料养分测试仪性能指标达到和超过了国家有关标准 ,其精度满足农村定量测土施肥的要求。
On the basis of analyzing the design technology of the soil quick tester, from the goal of quick testing soil nutrient of the low cost, the structure and principle of R&D of soil nutrient quick tester were proposed. The design mentality and the realization method of the YN soil nutrient tester were introduced. The measured data have indicated that the performance index of the YN soil nutrient tester achieves and has surpassed the national related standards. Its precision satisfies the request of quantitative testing soil and applying fertilizer in the rural area.
