摘要
根据我国各地 2 5 6份代表性大豆地方品种在南京分期播种、延长或缩短光照长度各处理条件下的生育期表现 ,结合供试材料来源地的地理与气候条件、播种季节类型、熟期组类型以及光温反应特性等因素 ,将我国大豆品种生态区划分为 :北方一熟制春作大豆品种生态区 (Ⅰ ) ,黄淮海二熟制春夏作大豆品种生态区 (Ⅱ ) ,长江中下游二熟制春夏作大豆品种生态区 (Ⅲ ) ,中南多熟制春夏秋作大豆品种生态区(Ⅳ ) ,西南高原二熟制春夏作大豆品种生态区 (Ⅴ ) ,华南热带多熟制四季大豆品种生态区 (Ⅵ )等六大区、10亚区 ,并阐述各区的一般生态条件及代表生态类型 .
Based on the climatic and geographical condition,cropping system and season sowing types and maturity group (MG) types of 256 varieties in test from total cultivating regions of soybean in China,six ecological regions of soybean were suggested.Those are:Northern single coropping,spring planting eco-region(Ⅰ),Huanghuaihai double cropping,spring and summer planting eco-region(Ⅱ),Middle and lower Changjiang valley double corpping,spring and summer planting eco-region(Ⅲ),Central south multiple cropping,spring,summer and autumn planting eco-region(Ⅳ),Southwest plateau double cropping,spring and summer planting eco-region(Ⅴ),and South China tropical multiple cropping,all season planting eco-region(Ⅵ).The cultivating environmental condition and representative varieties were shown,and the characteristics of all ecological regions of soybean in China were also discussed in this paper.
