作者分析了贵州从东到西,随海拨的升高,不同播期的大豆生育期,植株性状,生产力的生态变化特点,特别探讨了花期凹曲线分布的成因,及与结荚的关系。并分析了不同类型品种对贵州不同生态区气候条件的两种适应方式——避性和耐性。据此提出了贵州典型生态区的育种、引种和农艺目标。 The author analyzed the ecological characteristics of the growing period, the plant characters and the productivity of soybean in different sowing dates from east to west in Guizhou Province. The reasons of the concave curve distribution in flowering and the relationship with the pods were analyzed. Two kinds of adaptation modes of different types of cultivars to climatic conditions in different ecotopes in Guizhou were analyzed, such as avoidance and tolerance. Based on this, the breeding, introduction and agronomic goals of the typical ecological area in Guizhou were put forward.
