高产·早熟夏播大豆品种比较

Variety Comparison on Summer Sowing Soybean Varieties with High Yield and Early-Maturity

[目的]筛选适宜在山西省中部地区与冬小麦复播种植,且品质优良的高产、早熟夏播大豆品种。[方法]以4个大豆品种为试验材料,比较不同品种间生育期、产量性状及营养成分的差异。[结果]晋豆25号和晋大早黄2号生育期均为102 d,麦后复播可以正常成熟;晋大早黄2号的产量及蛋白质含量高于晋豆25号,但其出油率低于晋豆25号。[结论]晋豆25号和晋大早黄2号2个品种各有优势,可以在山西省中部地区小麦收获后复播种植。

[Objective] To screen suitable summer-sowing soybean varieties after wheat harvest in central Shanxi Province, which can early mature with high yield and good quality. [ Method] Comparative experiment was carried out with four soybean varieties as material, growth pe- riod, yieht characters and nutrient composition were compared. [ Result ] The growth period of Jindou No. 25 and Jindazaohuang No. 2 were 102 d, which can normal mature;The yield and protein content of Jindazaohuang No. 2 were higher than Jindou No. 25, but the oil extraction rate was lower. [ Conclusion] Two varieties have their own advantages, which can be multiple planting after wheat harvest in the central region of Shanxi Province.
