Total of 11 persons of Utsunomiya University visited China, and total of 10 Chinese scientists of Zhejiang Agricultural University, Hangzhou, China, visited Japan to perform comparative studies on the agriculture of Japan and China. The studies were focused on rice production, weed control in patty field, animal production, vegetables, especially aquatic species cultivation, sericulture, and basic and applied plant pathology. 1. Zhejiang Province and Japan have a current problem in common that the rural population has been decreasing seriously. The Province needs essential increase in food production. Rice varieties bearing high productivity are most desirable, and saving of labor other than machanization is required urgently in China. 2. Weed species and community changes in paddy field, methods and effect of weed control, and present problems in weed management in Japan and China were studied. Major problems in weed control are establishment of weed management, protection of paddy fi … More eld ecosystem and development of new weed control methods without herbicide. 3. In the field of animal production, the present status of animal industry and the production techniques were comparatively studied by the field survey in Japan, whole China and Zhejiang Province. 4. Differences of culturing techniques and commercial production of aquatic vegetables including lotus root and water bamboo etc. between Japan and China were studied. 5. Differences in the quality and productivity of cocoon between Japan and China were noticed. Improvement of sericulture system in China might be needed after Japanese experience. 6. A variety of plant materials which had possible virus or mycoplasma etiology were collected in Zhejiang Province and in Japan. Cooperative studies were done to find out the pathogen of each material. A segment of 16S ribosomal DNA was isolated in Zephyranthes candida with yellows symptoms, and the sequence of the DNA was analyzed. A model was established which will contribute to the promotion of cooperative studies between two colleges. Less

宇都宫大学共11人访问了中国，浙江农业大学、杭州、中国共10名中国科学家访问了日本，对日本的农业和中国进行了比较研究。这些研究集中在水稻生产、肉豆田杂草防除、动物生产、蔬菜，特别是水生物种栽培、蚕桑以及基础和应用植物病理学。1.浙江省和日本都有一个共同的问题，即农村人口一直在严重减少。该省需要大幅度增加粮食生产。高产水稻品种是最可取的，中国迫切需要节省机械化以外的劳动力。2.研究了日本和中国的稻田杂草种类和群落变化、杂草防除方法和效果，以及目前杂草管理中存在的问题。杂草防除的主要问题是杂草管理的建立、稻田FI…的保护更成熟的生态系统和开发新的无除草剂除草方法。3.在畜牧业生产方面，通过对日本、中国全省和浙江省的实地考察，对我国畜牧业现状和生产技术进行了比较研究。4.研究了日本与中国等水生蔬菜的栽培技术和商品化生产的差异。5.比较了日本和中国在蚕茧品质和产量上的差异。借鉴日本经验，中国的养蚕体系可能需要改进。6.在浙江省和日本采集了多种可能存在病毒或支原体病原学的植物材料。为了找出每种材料的病原体，进行了合作研究。从黄化症状的狼毒中分离到一段16S核糖体DNA片段，并对其进行了序列分析。建立了一个模式，将有助于促进两所学院之间的合作学习。较少
