【摘要】 作物品种研究已经由定性研究向更深层次的定量研究发展,分析评价是一种较为常用的定量研究方法,而评价指标体系及其权重则是评价体系的基础,对评价结果的科学性起着重要作用。以藜麦为研究对象,根据藜麦种植特性构建了一个由3个层、5个系统、15个具体指标组成的藜麦品种种植评价指标体系,并采用Delphi法与AHP法相结合的方法确定了各评价指标的权重。结果表明:从系统指标(第2层指标)权重来看,作物产能子系统在评价指标体系中占主要位置,其次是农艺性状子系统、子粒营养子系统、生态环保子系统,最后是土壤肥力子系统;从单个指标(第3层指标)权重看,亩产量对评价指标体系的贡献率最大,其次是抗倒伏率、千粒重、株高、蛋白质含量、子粒颜色、亩有机肥使用量、收获指数、脂肪含量、土壤有机质含量、淀粉含量、亩浇地用水量、土壤速效钾含量、亩农药使用量、土壤有效磷含量。计算结果与实际情况基本相符,所得到的评价指标体系及其权重能够比较客观地反映出该藜麦品种种植的实际情况。研究结果为藜麦品种种植评价奠定了基础。更多还原

【Abstract】 Crop variety research has developed from qualitative research to deeper quantitative research. Analysis and evaluation is a common quantitative research method,and the evaluation index system and its weight are the basis of evaluation system, which plays an important role in the scientificity of evaluation results. Taking quinoa as the research object,according to the planting characteristics of quinoa,the planting evaluation index system of quinoa varieties was constructed, which was composed of 3 layers, 5 systems and 15 specific indexes. The weight of each evaluation index was determined by combining Delphi method with AHP method.The results showed that from the weight of system index(the second level index), the crop productivity subsystem occupied the main position in the evaluation index system, followed by agronomic subsystem, grain nutrition subsystem,ecological environmental protection subsystem,and finally the soil fertility subsystem. From the weight of single index(the third layer index),the yield per mu had the largest contribution to the evaluation index system, followed by lodging resistance rate, 1 000 grains weight, plant height,protein content,grain color,organic fertilizer rate per mu, harvest index, fat content, soil organic matter content, starch content, water consumption per mu,soil available potassium content, pesticide usage per mu, and soil available phosphorus content. The calculated results are basically consistent with the actual situation,and the evaluation index system and its weight can objectively reflect the actual situation of quinoa planting. The results lay a foundation for planting evaluation of quinoa varieties.更多还原
