[目的]比较研究不同大豆(Glycine max)品种各生育期生理特性及产量,筛选出适合于河北张家口地区种植的高产品种,采用各种调控措施,实现大豆高产优质生产.[方法]14个供试大豆品种分别为东北地区引种的长农18、绥农14、长农16、吉农24、黑农38、吉农15、吉育47、吉农6、吉林30、吉农23、吉农1号、吉农12、吉农14和206.测定苗期、结英期、鼓粒期和成熟期株高、叶面积指数、叶绿素含量,并统计产量,并分析4个时期株高、叶面积指数、叶绿素含量与产量的相关性.[结果]吉林30的产量最高,达到16.839 kg/小区,206次之,为13.989.kg/小区.不同大豆品种叶面积指数在结英期和鼓粒期与产量的相关系数较大,在鼓粒期达到显著或极显著正相关;结英期和鼓粒期的叶绿素含量与产量呈显著或极显著正相关；鼓粒期的株高与产量呈显著正相关.[结论]该研究筛选出了适合于张家口地区种植的高产品种吉林30和206,同时阐明了不同生理生化指标和产量的关系,为栽培技术的合理利用及生态育种指标的有效选择提供了理论依据.%[Objective] The purpose was to comparatively study different soybean varieties' physiological characteristics and yield during ever-y growth period, screen high yield soybean varieties suit for planting in Zhangjiakou Region of Hebei, and realize its high yield and good quality production by all kings of controlling measures. [Method] Fourteen soybeans introduced from Northeast Region were Changnong18, Sui nong14 , Changnong16, Jinong 24, heinong38, Jinong 15, JiYu 47, Jinong6, Jilin 30, Jinong 23, Jinong 1, Jinong 12, Jinong 14 and 206 respectively. Plant height, leaf area index, chlorophyll content at seedling stage, pod setting stage, seed filling stage and mature stage were determined and yield was counted, then their corelation were analyzed. [Method] In fourteen soybeans, Jilin 30' s yield was the highest with 16.839 kg/plot, 206 was the second with 13.989 kg/plot. All kings of soybeans' leaf area index at pod setting stage and seed filling stage had a bigger corelation with yield, and reached a significant or very significant posilive corelation level at seed filling; Chlorophyll content at pod setting stage and seed filling stage had a 9ignifican1 or very significant positive corelation with yield ; Plant height at seed filling had a significant corelation with yiled. [Conclusion] The study screens high yield soybean varieties suit for planting in Zhangjiakou Region of Hebei, Jilin 30 and 206, and clarifies the relations between different physiological and biochemical index and yield at the same time, which provides a theoretical basis for reasonable utilization of cultivation technology and effective choosing of ecological breeding index.
