摘要
采用灰色关联度分析法对8个甜高粱(Sorghum dochna)品种的9个性状进行综合评价。结果表明:在青海东部农业区表现较好的甜高粱品种有九甜杂三、大力士、超级放牧者,而吉甜3号和辽甜1号的生产性能较差。各项指标的权重大小顺序为单株干质量>分蘖数>鲜干比>鲜重产量>主茎粗>单株鲜质量>出苗率>株高>绿叶数,研究结果可为该地区甜高粱的引种及推广提供科学依据。
The grey correlative degree analysis was applied to comprehensively evaluate the growth performance of 8 sweet sorghum varieties by nine characteristics.Three varieties including Jiutianzasan,Hunni green and Super herder performed well,whereas Jitian 3 and Liaotian 1 had relatively low suitability in the eastern agricultural region of Qinghai province.The order of weight index in the grey correlation analysis was plant dry weighttillers numberfresh to dry ratiofresh yieldstem diameterplant fresh weightemergence rateplant heightgreen leaf count.This result will provide a scientific evidence for introducing and extending sweet sorghum in the region.
