Applied and fundamental studies on the fjoating culture system in the waters

这项由中日科学家共同开展的国际联合研究项目，旨在研究用漂浮培养的植物去除水中有害化学物质包括重金属和阴离子表面活性剂（SDS）的可能性，这种植物可用于净化富营养化的河流和湖泊。1994年中国水稻研究所在天然河流下漂浮栽培的水稻中部分重金属含量是1995年在冈山大学生物资源研究所测定的。5名日本科学家于1996年3月15日至22日访问了CNRRI，以冈山大学分析的数据为基础，审查并建立了漂浮培养植物消除重金属和SDS的实验方案。3 .日本科学家在中国科学研究中心进行小麦浮培试验时，向中国科学家传授了生长分析测量方法和水质标准分析方法。收集了中国一些河流和湖泊的分析用水，并将其带到日本，了解目前水体中重金属和SDS的含量。中国科学家邹国彦应邀赴日本接受重金属分析方法和SDS培训。培训于1996年2月25日至3月31日在冈山大学生物资源研究所进行。1996年3月1日至15日，中国科学家宋祥福应邀到日本收集有关日本水质净化研究的资料，并与日本科学家讨论总结这一国际联合研究项目。

This International Joint Research Project with Chino-Japanese scientists conducted to examine possibility of elimination of harmfuly chemical substances Include heavy metals and anion surface-active agents (SDS) from the waters by plant grown with floating culture which is useful for water cleaning of eutrophied reivers and lakes.1. Some heavy metal contents in rice plant grown with floating culture under the natural river at China National Rice Research Institute (CNRRI) in 1994 were etermined at Research Institute for Bioresurces, Okayama Universityiin 1995.2. Five Japanese scientists visited CNRRI from March 15 to 22,1996 to examine and establish the experimental program on the elimination of heavy metals and SDS by floating culture plants based on the date analized at Okayama Univ.3. Japanese acientists taught to Chinese scientists measuring method for growth analysis and analytical method of water quarity criteria at experimental field where was doing floating culture of wheat plants at CNRRI.4. Water for analysis of some rivers and lakes in China were collected and they werebrought to Japan to know contents of heavy metals and SDS in the waters at present.5. A Chinese scientist (Guoyan Zou) was invited to Japan for trainning of analytical method of heavy metals and SDS.The trainning was carried out at Research Institute for Bioresurces, Okayama University from Feburary 25 to March 31,1996.6. A Chinese scientist (Xiangfu Song) was invited to Japan to collect information on water quarity cleaning research in Japan and to discuss about summarizing with Japanese scientists on this International Joint Research Project from March 1 to 15,1996.
