本文运用主成分分析和聚类分析相结合的数量分类方法,将1983和1984年分别种植的22和64个山西省各地区代表性品种,按5个生育期生态因子与5个生态农艺性状,分为14个生态类型。不同类品种各具特点,反应出山西省大豆品种资源的丰富多样性及明显的地域性。各类品种对光温反应均敏感,且感温性>感光性;晚熟类型>中熟类型>早熟类型。生态分类的主要因子是出苗——开花日数、全生育期的日数、积温以及百粒重、主茎节数、株高等;表明除生育期对生态型的形成起重要作用外,其他性状作为生态因子亦起一定作用。
In this paper, the principal component analysis and cluster analysis combined quantitative classification method, the 1983 and 1984 were planted in 22 and 64 representative varieties of Shanxi Province, according to five ecological factors and five stages of ecological agronomic traits, Divided into 14 ecological types. Different varieties have their own characteristics, reflecting the rich diversity of Shanxi province soybean resources and obvious geographical. All kinds of varieties are sensitive to light and temperature, and the temperature sensitivity> light; late-maturing types> maturing types> precocious types. The main factors of ecological classification are the emergence and flowering days, the days of the whole growth period, the accumulated temperature, the weight of one hundred kernels, the number of main stems and the height of the plant. It indicates that except for the growth period, the ecological traits play an important role, Factors also play a role.
