摘要:

目的 高粱是我国重要的多用途旱地经济作物，生产区域广，生态条件复杂，栽培方式多样，因此，构建高粱品种生态适应性评价指标体系对品种选择、种植规划等具有重要指导意义。方法 文章通过文献研究、生产调研和专家问卷调查，利用层次分析法，构建品种生态适应性评价的指标体系的层次结构；利用德尔菲法，利用橙子办公软件设计调查问卷，借助专家微信群对各指标的相对重要性进行专家问卷调查，使用SPSSAU优序图法，计算各指标权重。结果 根据反复征询意见，确定了各项指标的判分原则和标准，按综合得分将高粱品种生态适应性分为适应（≥90分）、较适应（76~89分）和不适应（≤75分）3类。根据所建评价方法对适应性评价试验中6个代表性品种，对其在6个地区的表现进行综合打分评价。结论 证明结果符合实际。

Abstract:

Sorghum is an important multi-purpose economic crop in dryland in China. In the context of its wide production area, complex ecological conditions, and diverse cultivation methods, it is very imperative to establish an evaluation index system for ecological adaptability of sorghum variety, which is of significance for guiding variety selection and planting planning. Through literature research, production research and expert questionnaire, the hierarchical structure of the index system of variety ecological adaptability evaluation was constructed by using analytic hierarchy process, and the Delphi method and orange office software were used to design the questionnaire, the expert WeChat group was used to investigate the relative importance of each index, then the SPSSAU priority chart method was used to calculate the weight of each index. According to repeated consultation, the scoring principles and standards of various indicators were determined, and based on the comprehensive score, the ecological adaptability of sorghum varieties was divided into three categories: adaptation (≥ 90 points), relatively adaptation (76~89 points) and non-adaptation (≤ 75 points). According to the established evaluation method, six representative varieties was comprehensively scored and evaluated in 6 regions. It concludes that the results are proved to be in line with the reality.
