毕节地区640多万亩耕地,分布在海拔457公尺到2600多公尺的范围内,有立体农业的特征。作物组合垂直变化的规律显著。地区东部:低中山、低山地貌,年均温15℃左右,≥10℃的积温4100℃以上,气候温暖,属连作两熟区。其中赤水河、鸭池河等河谷地带,气候温热。地区中部:中山、高中山地貌,年均温13℃左右,≥10℃的积温3300—4100℃,气候温和,属套作两熟区。地区西部:高原、高中山地貌,年均温11℃左右,≥10℃的积温3300℃以下,气侯温凉,属一年一熟和两年三熟区。其中习惯称高原缓丘部份为半凉山,高原山脊部份为凉山,气候冷凉。
More than 640 million mu of cultivated land in Bijie area is distributed within the range of 457 meters above sea level to more than 2600 meters and has the characteristics of three-dimensional agriculture. The vertical variation of crop combinations is significant. The eastern part of the region: low Zhongshan, low mountain topography, annual average temperature of about 15 ℃, ≥ 10 ℃ accumulated temperature above 4100 ℃, warm climate, is continuous cropping two ripening areas. One Chishui River, duck pond river valley, the climate is warm. Central region: Zhongshan, high mountain landscape, with an average annual temperature of about 13 ℃, ≥ 10 ℃ accumulated temperature 3300-4100 ℃, mild climate, is a set of two ripening area. The western part of the region: plateau, high mountain landscape, with an average annual temperature of about 11 ℃, ≥ 10 ℃ accumulated below 3300 ℃, the climate is cool, a year and a three-year ripening area. Among them, it is customary to say that part of the plateau is a semi-cool mountain, and that part of the plateau is Liangshan with a cold climate.
