1甜高粱生产现状甜高粱具有光合效率高、生物产量高、糖分含量高、适应性强、抗旱、耐涝、耐盐碱的特点,是一种高效节水型作物,适合于西北大部分地区种植。甜高粱的育种与核辐照技术运用密不可分,采用重离子辐照诱变技术可快速获取适合西北沙荒、盐碱等边际性土地的新种质资源,加快新品种选育进程。2012年,武威市从中科院近代物理研究所引进醇用型和饲用型甜高粱品种2个,在凉州区、民勤县、古浪县选定7个试验点试种。结果表明,饲用型甜高粱在武威大部分地区生长旺
1 sweet sorghum production status Sweet sorghum has photosynthetic efficiency, high biological yield, high sugar content, adaptability, drought, waterlogging, salinity tolerance is a water-efficient crops, suitable for most parts of Northwest China Planting. The breeding of sweet sorghum and the application of nuclear irradiation technology are inseparable. Using heavy ion irradiation mutagenesis technology can quickly obtain new germplasm resources suitable for the marginal land of desertification, salt and alkali in Northwest China and speed up the breeding process of new varieties. In 2012, Wuwei introduced 2 varieties of alcohol-type and sweet-type sorghum from the Institute of Modern Physics, Chinese Academy of Sciences, and selected 7 pilot sites in Liangzhou District, Minqin County and Gulang County. The results showed that forage sweet sorghum grew well in most parts of Wuwei
