摘　　要：本试验以4个春大豆品种垦丰16、东农豆252、东农豆254和东农豆255为试验材料,在垄作条件下以其最适密度播种,探索春大豆不同品种农艺性状、产量及品质之间的差异。结果表明,农艺性状方面,垦丰16的平均株高、节间长度、节数和单株粒数性状较好,分别为91.89 cm、4.79 cm、19.93个和127.93粒/株;东农豆252的平均株高和百粒重性状较好,分别为82.47 cm和24.07 g;东农豆254的平均节间长度和单株粒数性状较好,分别为5.80 cm和162.53粒/株。产量方面,垦丰16、东农豆252、东农豆254和东农豆255产量分别为3006.60 kg/hm 2、2790.30 kg/hm 2、2097.93 kg/hm 2和1903.77 kg/hm 2,垦丰16和东农豆252产量显著高于东农豆254和东农豆255。品质方面,垦丰16、东农豆252、东农豆254和东农豆255蛋白质含量分别为41.47%、43.83%、43.97%、44.40%,脂肪含量分别为20.37%、20.30%、19.30%、19.97%,东农豆255蛋白质含量最高,垦丰16脂肪含量最高。In this experiment,four spring soybean varieties(Kenfeng 16,Dongnongdou 252,Dongnongdou 254 and Dongnongdou 255),were used as experimental materials,and planted at the most optimum density under ridge culture to explore the differences of spring soybean with different varieties in agronomic characters,yields and qualities.The results showed that the average plant height,internode length,internode number and grain number per plant of Kenfeng 16 were 91.89 cm,4.79 cm,19.93 and 127.93 grains/plant,respectively.The average plant height and 100-grain weight of Dongnongdou 252 were 82.47 cm and 24.07 g,respectively.The average internode length and grain number per plant of Dongnongdou 254 were 5.80 cm and 162.53 grains/plant,respectively.In terms of yield,the yields of Kenfeng 16,Dongnongdou 252,Dongnongdou 254 and Dongnongdou 255 were 3006.60 kg/hm 2,2790.30 kg/hm 2,2097.93 kg/hm 2 and 1903.77 kg/hm 2,respectively.The yields of Kenfeng 16 and Dongnongdou 252 were significantly higher than those of Dongnongdou 254 and Dongnongdou 255.In terms of quality,the protein contents of Kenfeng 16,Dongnongdou 252,Dongnongdou 254 and Dongnongdou 255 were 41.47%,43.83%,43.97%and 44.40%,respectively,and the fat contents were 20.37%,20.30%,19.30%and 19.97%,respectively.Dongnongdou 255 had the highest protein content,and Kenfeng 16 had the highest fat content.
