黑河地区位于祖国的最北部,土质比较肥沃,适于大豆栽培,全区大豆栽培面积约300万亩。全区各地年平均气温在-2～1℃,降水量470～600毫米,无霜期80～130天,日照时数2400～2800小时/年,5～8月达900～1000小时。全年≥10℃积温在1500～2450℃,作物生育季节昼夜温差14～19℃. 本区虽处于高寒地带,气温较低,但作物生育期光照时间长、强度大。降水量虽少,主要集中
Heihe region is located in the northernmost part of the motherland, fertile soil, suitable for soybean cultivation, the region soybean cultivation area of about 3000000 acres. The annual average temperature throughout the region -2 ~ 1 ℃, precipitation 470 to 600 mm, frost-free period 80 to 130 days, sunshine hours 2400 to 2800 hours / year, 5 to August 900 to 1000 hours. In the whole year, the accumulated temperature of ≥10 ℃ is between 1500 and 2450 ℃, and the temperature difference between day and night of crop growth season is between 14 and 19 ℃ .Although the area is in the alpine zone, the temperature is low, but the growing period of the crop is long and the intensity is high. Precipitation is small, mainly concentrated
