摘　　要：本文对冬小麦根系与地上部生长状况作了系统分析,结果表明,单株次生根数与分蘖数、根干重与冠干重、叶面积与总吸收面积、活跃吸收面积等存在相关关系;根冠比反映着各自干物质积累的特点,与经济系数关系密切;根系活性与叶片衰老、产量构成相关。Systematic analysis of growth status between root system and top in winter wheat showed that for single plants there existed correlations of secondary roots to tillers,root dry weight to crown dry weight,leaf area to total absorption area and active absorption area. Root/crown ratio which related closely to economic coefficient reflected characteristics of dry matter accumulation.Special attention must be paid to activity of root system which correlated to leaf aging and grain yield.
