摘 要：
Soybean is an important crop in China and is planted everywhere except on the higher plateaus where the weather is too cold or too dry. Statistics of the Chinese Ministry of Agriculture show that its acreage was 8.2 million hectares throughout the country, yielding a total harvest of 9.3 million metric tons in 1981. The production is mainly concentrated in eight provinces namely Heilon jiang, Henan, Anhui, Shangdong, Jilin, Liaoning, Hebai and Jiangsu though it varies in order from year to year. These eight provinces are situated in the Northeast and North China Plains, then the next places are in the middle reaches of Huanghe (the Yellow River) and Chang Jiang (the Yangtze River).According to the natural factors such as effective cumulative temperature, frostless days, rainfall, photoperiod and the differences of farm system in different places, we divided the soybean cultivation area of China into three regions and ten sub-regions as follows:Ⅰ. Northern Single Cropping Spring Planting Region: 1. Northeastern Spring Planting Sub-region:Includes east side from Great Xing An Mt., those are the provinces of Heilongjiang, Jilin, Liaoning and Northeastern Inner Mongolia district. 2. North Plateau Spring Planting Sub-region: Includes Southwestern Inner Mongolia, north from Great Wall, those are the northern parts of Hobei, Shanxi and Shanxi.3. Northwestern Spring Planting Sub Region. The oasis of Xinjiang district.Ⅱ. Huang, Huai and Hai Valleys Double Cropping Summer Planting Region.4. Hai Valley Summer and Spring Planting Sub-region: Includes the middle parts of Hobei and Shanxi provinces.5. Huang and Huai Valleys Summer Planting Sub-region:Includes Shandong, most part of Henan, southern Hobei, southern Shanxi, north parts of Anhui and Jiangsu, and the middle part of Shanxi.Ⅲ. Southern Multiple Cropping Many Planting Region:6. Chang Jiang Valley Summer and Spring Planting Sub-region: Includes parts of provinces along the Chang Jiang Valley.7. Southeastern Autumn and Spring Planting Sub-region;Includes southern Zhejiang, northeastern Jiangxi,most part of Fujian and he whole Taiwan.8. Middle Southern three Plantings Sub region:Includes most parts of Hunan, Guangdong, Guangxi provinces, and southwestern Jiangxi.9. Southwestern Plateau Spring and Summer Planting Sub-region. Includes most parts of Guizhou and Yunnan provinces, western Guangxi,Sichuan and Hunan provinces.10. Tropical Multiple Planting Sub-region:Includes the tropical parts of Guangdong, Guangxi And Yunnan.The limit of the area for soybean cultivation is where the cumulativ temperature of ≥ 10℃ below 1,900℃ or with an annual rainfall less tha 250 mm and nonirrigation area as like the provinces of Gansu and Qinghai, and the districts of Inner Mongolia and Tibet.
