自50年代开始,日本国在农业领域开展原子能利用研究,近年来发展很快。目前除继续进行基础性的研究工作外,在农业、林业、畜牧、食品加工保鲜、环境保护等方面开展研究和利用。从应用情况来看有,: 一、射线的利用 (一)作物育种辐射育种巳成为一种重要的育种手段。国立农技所从1949年起开展突变育种及有关理论研究,1960年成立辐射育种场。以γ-线为主,先后建成农用钻圃、γ照射室、γ-温室等设施。到1985年底,直接辐射育成的各种作物品种达45个,间接育成品种23个。曾较大面积推广的有“黎明”水稻,“雷电”大豆等品种,取得了一定的经济效
Since the 1950s, Japan has conducted research on atomic energy utilization in agriculture and has developed rapidly in recent years. In addition to continuing to carry out basic research work, research and utilization are carried out in agriculture, forestry, livestock husbandry, food processing and preservation, and environmental protection. From the application of the situation there are: First, the use of radiation (A) crop breeding Radiation breeding has become an important means of breeding. National Agricultural Technology Institute since 1949 to carry out mutation breeding and related theoretical research, in 1960 the establishment of radiation breeding farm. To γ-line-based, has completed the construction of agricultural nursery, γ irradiation room, γ-greenhouse and other facilities. By the end of 1985, there were 45 varieties of crops cultivated by direct radiation and 23 indirectly cultivated varieties. Has a larger area to promote the “Dawn” rice, “Lightning” soybeans and other varieties, and achieved some economic
