摘要
人工设置瘠薄地块，对高粱进行耐瘠性鉴定，应用耐瘠指数和出苗至开花延迟天数两个分级指标，结合田间目测评级，对养分胁迫下高粱受害程度、产量降低水平和植株死亡等与对照区品种比较，划分品种的抗性等级，从高粱种质资源中筛选出一级耐瘠品种77份。
Screening test for poor fertility tolerance was conducted in the artificially formed barren field and check fertile field. The test materials of sorghum was classified according to the degree of poor fertility tolerance,which was based on field,the tolerance index,the number of days from emergence to flowering,the number of abnormal Plants and so on.
