在毛主席革命路线指引下,我所计量人员深入农村生产第一线,实行科研生产相结合。在深入调查的基础上,针对土壤盐分测定采用化学分析法存在着设备复杂、操作费时、药品供应不便等缺点,我们选用较少的元件、较简单的线路制作了 DYC-1型电导式水土盐分速测仪。该速测仪体积小、耗电少、制作方便、造价低;测定方法简易快速。在莆田地区农科所的大力支持下,经过在生产实践中和化学分析法的对比实验以及有关农业科研单位的协助鉴定,认为基本上克服了化学分析法所存在的各主要问题,测量精度
Under the guidance of Chairman Mao’s revolutionary line, the personnel of our measurement went deep into the first line of rural production and practiced the combination of scientific research and production. On the basis of further investigation, the chemical analysis method for soil salt determination has the disadvantages of complex equipment, time-consuming operation and inconvenient supply of medicines. We chose DYC-1 type conductivity salt water and soil salt with fewer components and simpler circuits Speedometer. The speedometer small size, low power consumption, easy production, low cost; determination method is simple and quick. Under the strong support of the Agricultural Science Institute in Putian, through comparison experiments in production practice and chemical analysis and the assistance identification of relevant agricultural research institutes, it is considered that the main problems of chemical analysis are basically overcome, the measurement accuracy
