摘要
我国东北地区的大豆以种植面积大、产量高、质量好著称，这与该地区环境条件有关。土壤腐殖质层厚，有机质含量在４０ｇ／ｋｇ以上，养分丰富，中性至酸性反映，壤质土，土壤紧实度适中，容重１．１～１．４ｇ／ｃｍ３，５～ｇ月降水在５００～６００ｍｍ左右，５～９月特别是８月气温偏低，在１９～２２℃。上述条件基本可以满足大豆高产优质的需要。
Soybean production in North-East China is well known aswidespread planting.High yield and fine quality. This is related to theenviroment and condition of this area: the soils with thick humic horizns,high organic matter content (over 40 gkg-1), abandant nutrients,neutrality to slightly acid, loamy texture suitable degree of com-paction(bulky density ranged from 1. 1 to 1. 4 gcm-3); 500-600 mm rainfall inMay-September, especially temperature in Angust slightly lower(19-20℃).Allof above conditions are essentially for high yield and fine quality soybean.
