A Study on Conventional Farming System and its Development -in the case of Southeast Asia-

1992年，我们在老挝和泰国进行了实地研究，1993年在湄公河三角洲和老挝进行了实地研究。我们得到了老挝农林部、越南坎托大学等机构和人员的帮助，1992年8月在老挝进行实地考察后，所有研究成员都参加了由Thamrong Prempridi教授组织的第四届东南亚农具和农业系统演变研究成果传播国际研讨会，也是我们研究团队的一员研讨会的目的是将在老挝实地研究中获得的知识传播给日本和东南亚国家的利益相关方，并将技术专家，社会科学家和工程师聚集在一起，就农业工具/机器，农业系统和相关主题交换意见。在老挝使用的农具仍然是传统的和当地制造的。实践中的耕作制度也有因地制宜的常规耕作制度，1993年又在湄公河三角洲、越南和老挝进行了实地考察。拖拉机、拖拉机、铣床在湄公河三角洲很常见。该地区的耕作制度，特别是种植模式变化很大，主要与自然条件相适应。湄公河三角洲目前采用的耕作制度可以说是积累了最适合当地条件和环境的知识、技能和技术。

We conducted field study in Laos and Thailand during 1992, and in Mekhong Delta and in Laos during 1993. We have been assisted by various institution and people, such as the Ministry of Agriculture and Forestry of Laos, University of Cantho, Vietnam and so on.After the field study carried out in Laos, August in 1992, All research members participated the fourth International Seminar on THE DISSEMINATION OF RESEARCH FINDINGS ON FARM TOOLS AND THE EVOLUTION FARMING SYSTEMS IN S.E.ASIA organized by Professor Thamrong Prempridi who is also one of our research team members. The object of the seminar were to dissiminate knowledge gained from field studies in Laos to interest parties in Japan and from countries in SE Asia, and to bring together technologists, social scientists and engineers to exchange views on farm tools/machines, farming system and related subject. Farm tools used in Laos are still traditional and locally made. Farming system put in practice there are also conventional which is fit to local conditions.In 1993 field study carried out in Mekhong Delta, Vietnam and Laos again. Tractor, threshing machine, milling machine are common in Mekhong Delta. Farming system, especially cropping patterns in the areas are very varying in Correspondence to mainly natural conditions. Farming system presently used in Mekhong Delta can be said to contain accumulated knowledge, skill and techniques which are most adaptive to the given local condition and environment.
