摘 要:依据2007年河北省夏大豆品种区域试验结果,分别采用通用高产稳产性参数估算、回归系数法和高稳系数法对石豆4号的高产稳产性进行了分析,以期为石豆4号的示范推广提供依据。3种方法的评价结果均表明:石豆4号具有较好的丰产性和稳产性,是一个比较理想的高产稳产大豆品种。对影响产量的主要经济性状进行分析,结果显示,产量与主茎节数、株高、单株有效荚数、单株粒重、有效分枝数和单株粒数呈正相关关系,与百粒重和底荚高呈负相关关系。生产实践中应该加强水肥管理,在大豆营养生长期保证株高和主茎节数,促进分枝,在大豆生长后期保证养分充足供给,促进养分向豆荚转移,从而提高产量。In order to provide the theoretical foundation for demonstrations and applications of Shidou No. d, using the results of soybean variety regional test of Hebei Province in 2007, the high and stable yield of Shidou No. 4 were analyzed by general parameters estimation, regression coefficient method and high stability coefficient method. The evaluate results of the three methods indicated that Shidou No. 4 had the high and stable yield, which was a better soybean variety. Analysis the characterises about the yield showed that the yield was positively correlated with the main stalk pitch number, plant heignt, effective number of pods per plant, the grain weight per plant, effective number of branches and the number of seeds per plant, and negatively correlated with the hundred grain weight and the bottom pod heignt. In the production practice, fertilizer and water investment should be increased, the plant height and the main stalk pitch number should be ensured in the soybean vegetative period to promote the branches, and the nutrition should be ensured in the later period to promote the nutrient transfer to pod, thus increasing the yield.
