在毛主席革命路线指引下,各地土壤和作物诊断的研究工作发展很快。自1974年以来,全国组织了土壤普查、土壤诊断研究协作组。参加这个协作组的单位有山东省土壤肥料研究所、湖南省农科院土肥所、中国科学院南京土壤研究所、北京市农科院、河北省植保土肥所、福建省农科院和浙江农业大学、华北农业大学、西南农学院、山东农学院。两年来,各协作单位在各级党的领导下,紧密联系生产实际,与群众性的科学实验相结合,对土壤和作物营养诊断和障碍诊断的速测方法进行了研究。但由于各地采用的速测方法不一,其测定结果差异很大,造成经验和资料交流不便,具体运用困难。为了使土壤和作物诊断速测方法更好地为农业学大寨、普及大寨县服务,1975年12月至1976年1月集中在湖南省农科院土肥所,首先就目前土壤和作物营养诊断速测方法存在的问题,进行了比较研究。关于物理性状、生物特性和其它障碍诊断的方法以后还要继续组织比较研究。参加这次工作的,除各协作单位外,中国计量科学研究院和湖南农学院也派人参加。在两年来研究和这次比较分析的基础上,各协作单位共同协商讨论编写成《土壤和作物营养诊断速测方法》一文。这次推荐的土壤和作物营养诊断速测方法,较我刊1975年第1期发表的《大搞科学种田积极开展土壤普查与诊断》中的速测方法有了改进和提高,但仍有不少缺点。欢迎广大读者在生产斗争和科学实验实践的运用中,不断加以验证,提出宝贵意见,以便今后进一步修改,逐步完善。 Under the guidance of Chairman Mao’s revolutionary line, the research work on soil and crop diagnosis has rapidly developed. Since 1974, the National Soil Census and Soil Diagnostics Research Collaboration Team has been organized nationwide. Participate in this collaborative group units are soil and Fertilizer Institute of Shandong Province, Hunan Provincial Academy of Agricultural Sciences Soil and Fertilizer Institute, Nanjing Institute of Soil Science, Chinese Academy of Sciences, Beijing Academy of Agricultural Sciences, Plant Protection and Fertilizer Institute of Hebei Province, Fujian Academy of Agricultural Sciences and Zhejiang Agricultural University North China Agricultural University, Southwest Agricultural College, Shandong Agricultural College. In the past two years, under the leadership of the party committees at all levels, all collaborating units have conducted research on the rapid test methods for the diagnosis of soil and crop nutrition and the diagnosis of obstacle, in close connection with production practice and with mass scientific experiments. However, due to the different speed measurement methods adopted in various places, the results of the determination vary greatly, which leads to the inconvenience of experiencing and exchanging data, and the specific application is difficult. In order to make soil and crop diagnostic rapid test method better for Dazhai Agricultural Science and popularize Dazhai County service, from December 1975 to January 1976, focus on the Soil and Fertilizer Institute of Hunan Academy of Agricultural Sciences. At first, the current soil and crop nutrition Diagnose the problems of quick test method, and make a comparative study. Methods for the diagnosis of physical traits, biological traits and other disorders will continue to be organized later. Participate in this work, in addition to the collaboration units, the China Institute of Metrology and Hunan Agricultural College also sent to participate. On the basis of two years of research and comparative analysis, all the collaborators jointly negotiated and compiled a paper entitled “Methods for Quick Diagnosis of Soil and Crop Nutrition.” The proposed soil and crop nutrition diagnostic rapid test method, compared with my published in 1975 No. 1 published “vigorously carry out scientific investigations and diagnostics of soil in the scientific farming,” the method has been improved and improved, but still not Less disadvantage. Welcome readers in the production struggle and the use of scientific experimental practice, continue to be verified, put forward valuable opinions for future further amendments, and gradually improve.
