【摘要】 在前人关于中国大豆栽培区域划分的基础上．根据我国各地２５６份大豆地方品种在南京分季播种、延长或缩短光照长度各处理条件下的生育期表现，结合供试材料的来源地地理与气候条件、播种季节类型、熟期组归属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－熟制春作大豆品种生态区、黄淮海二熟制春夏作大豆品种生态区、长江中下游二熟制春夏作大豆品种生态区、中南多熟制春夏秋作大豆品种生态区、西南高原二熟制春夏作大豆品种生态区和华南热带多熟制四季大豆品种生态区等６大区，并在其中３个区内进一步划分亚区。更多还原

【Abstract】 According to (1) the performances of growth period traits of 256 soybean landraces from all producing areas in China under the natural and artificial conditions of various planting seasons and normal and extended day length in Nanjing, (2) their maturity groups, original planting season types, and the ge- ographic and climatic conditions at their original places, and (3) historical grouping systems of soybean cultivation areas in the literature, a soybean varietal eco-region system in China was proposed which divid- ed the whole country into six eco-regions as the following: 1. Northern Single Cropping Spring Planting Varietal Eco-Region (NRT VER), including Northeast Sub-Region (Ⅰ -1 NEC SR), Northern Plateau Sub-Region (Ⅰ -2 NCP SR ), and Northwest Sub-Region (1 -3 NWC SR );Ⅱ. Huang-Huai-Hai Double Cropping Spring and Summer Planting Varietal Eco-Region(HHH VER ), including Hai-Feng Sub-Region (Ⅱ-1 HFV SR). and Huang-Huai Sub-Reglon(Ⅱ-2 HHV SR); Ⅲ. Middle and Lower Changjiang Valley Double Cropping Spring and Summer Planting Varietal Eco-Region (MLS VER); Ⅳ. Central South Mul- tiple Cropping Spring Summer and Autumn Planting Varietal Eco-Region (CTS VER), including Eastern Middle South Sub-Region (Ⅳ -1 EMS SR), and Western Middle South Sub-Region (Ⅳ -2 WMS SR); V. Southwest Plateau Double Cropping Spring and Summer Planting Varietal Eco-Region(SCT VER); and VI South China Tropical Multiple Cropping All Season Planting Varietal Eco-Region (SCT VER).更多还原
