武清县地处北纬39°21′~39°42′,东经116°48′~117°21′之间,属海河低平原区。年平均气温11.6℃,≥10℃积温4 169.1℃,无霜期207天,日照4 476.3小时,年降雨量606.8毫米。据普查,全县土壤缺磷少氧,土壤肥力中等偏下。武清县属于冬、春小麦,春、夏玉米过渡地带,全县热量一季有余,两季不足。随着农村改革不断深化,农田基本建设不断发展,机械化和农业科学技术水平的不断提高,三秋、三夏的农耗积温大大缩短,以小 Wuqing County is located in the lowland area of ​​Haihe River between 39 ° 21’-39 ° 42’N and 116 ° 48’-117 ° 21’E. The annual average temperature of 11.6 ℃, ≥ 10 ℃ accumulated temperature of 4 169.1 ℃, frost-free period of 207 days, 4 476.3 hours of sunshine, the annual rainfall of 606.8 mm. According to the census, the county’s soil lack of phosphorus and oxygen, soil fertility is moderately lower. Wuqing County belongs to winter, spring wheat, spring, summer corn transition zone, the county more than a quarter of heat, less than two quarters. With the continuous deepening of rural reform, farmland capital construction continues to develop, mechanization and agricultural science and technology continue to improve, three autumn, three summer agricultural consumption accumulated temperature is greatly reduced to small
