研究了建国以来黑龙江省选育的１４８个大豆品种的蛋白质、脂肪、碳水化合物和灰分含量的变化及其生态地理分布。伴随着品种生产潜力的提高，该省育成品种的脂肪含量略有提高，蛋白质含量有明显的下降，但８０年代又有回升；碳水化合物和灰分含量变化不大；蛋白质和脂肪含量生态地理区域间差别较大，克拜和绥化地区育成的品种蛋白质含量高，黑河与嫩江地区育成的品种脂肪含量高，碳水化合物和灰分含量地区之间差异不大。
The changes of protein, fat, carbohydrate and ash content in 148 soybean varieties bred in Heilongjiang Province since the founding of the People’s Republic of China and their eco-geographical distribution were studied. With the improvement of variety production potential, the fat content of the bred varieties slightly increased and the protein content decreased obviously in the 1980s, but rose again in the 1980s; the content of carbohydrate and ash did not change much; the content of protein and fat in the eco-geographical areas The difference is relatively large. The protein content of varieties cultivated in Qibai and Suihua areas is high, and the varieties cultivated in Heihe and Nenjiang areas have high fat content and little difference between carbohydrate and ash content areas.
