在华国锋同志关于“全党动员,大办农业,为普及大寨县而奋斗”报告的鼓午下,我们根据当地土质盐碱的实际情况,开展了土壤盐分测定工作,考虑到推广科学种田的需要,又重点进行了全盐和氯根含量关系的研究,目的是找出测定全盐的一种方法,这种方法通过简单快速的容量法测定氯根,就可以算出全盐含量来。我们选择三个大队六个小队有代表性的地块在1975年秋后10—12月返盐季节进行了定期取样分析,在对所获得的数据作处理和分析时,初步发现全盐和氯根含量之间存在一定的关系,其结果如下:
Under Dr. Hua Guofeng’s report on the report of “mobilization of the entire Party, large-scale operation of agriculture and popularization of Dazhai County,” we carried out the determination of soil salinity according to the actual conditions of the local soil saline and alkali, taking into account the promotion of science Farming needs, but also focused on the relationship between total salt and chloride content, the purpose is to find out a method for determination of total salt, this method by simple and rapid volumetric method for the determination of chloride, you can calculate the total salt content . We selected the three brigades of the six groups of representative plots in the autumn of October 1975 back to the salt season, a regular sampling analysis, obtained in the data for processing and analysis, the initial discovery of all salt and chloride There is a certain relationship between the content, the results are as follows:
