在中国土壤学会土壤—植物营养专业委员会和江苏省土壤学会共同主持下,全国中量、微量元素研究学术讨论会于1993年8月15—20日在苏州召开。来自农业科研单位、高等院校和农业技术推广部门的54位代表出席了会议。会议收到论文53篇。会议回顾了我国十年来中,微量元素研究与应用的进展。土壤有效性微量元素的丰缺状况已由定性的概念进而对缺乏、适宜、过量提出了定量的指标,作物营养已由局限于微量元素含量分析,进而研究营养元素的生理、生化效应和对作物解剖结构的影响。此外,在诊断方法、分析技术方面也有了很大进步。在此基础上生产出一些作物专用肥,在生产上取 Under the co-sponsorship of the Soil-Plant Nutrition Professional Committee of China Soil Society and Soil Society of Jiangsu Province, the National Symposium on Medium and Trace Elements Research was held in Suzhou on August 15-20, 1993. 54 representatives from agricultural research institutes, universities and agricultural technology promotion departments attended the conference. The meeting received 53 papers. The meeting reviewed the progress of research and application of trace elements in China over the past decade. Soil availability The abundance and deficiency of trace elements have been quantitative indicators of lack of, appropriate and excessive from the concept of qualitative, crop nutrition has been limited to the trace element content analysis, and then study the physiological and biochemical effects of nutrients and the crop Effect of anatomy. In addition, great advances have also been made in diagnostic methods and analytical techniques. On this basis to produce some of the crop fertilizer, take in the production
