黑河地区位于黑龙江省北部(北纬41°21′至51°01′之间,气候寒冷(年平均气温-2.0～1.0℃、≥10℃的活动积温1600～2400度) ,生育期短(85～125天),对大豆生育不十分有利。大豆是本区主要的油料和经济作物,播种面积(不包括省属农场)历年占总播种面积25％左右,因此本区是省重点商品大豆基地之一本区大豆栽培从60年代起,生产上一直是推行以群体增产为主。一般用繁茂性中等的早熟品种,
The Heihe region is located in the northern part of Heilongjiang Province (latitude 41 ° 21 ’to 51 ° 01’, with cold climate (annual average temperature -2.0 ~ 1.0 ℃, active accumulated temperature 1600 ~ 2400 ℃ ≥10 ℃) 125 days), is not very beneficial to soybean growth.Soybean is the main oil and cash crops in this area, sown area (excluding provincial farms) over the years accounted for about 25% of the total sown area, so the area is the provincial key soybean base A district of soybean cultivation from the 60s onwards, the production has been the mainstay of the group to increase production.General use of luxuriant medium-sized precocious varieties,
