关于大豆生育阶段与产量关系方面的研究，国内外曾有过报导。这些报导仅在大豆生育阶段与产量相关方面，或在不同栽培措施下研究大豆发育天数与产量的关系。为了进一步明确大豆各生育阶段的长短对产量性状作用实质，更有效地指导育种工作实践，本文在大豆品种资源研究中，... Research on the relationship between soybean growth stage and yield has been reported both at home and abroad. These reports only study the relationship between the number of days of soybean development and the yield of soybean in terms of yield-related aspects of the growth stage or under different cultivation practices. In order to further clarify the effect of the length of each stage of the growth of soybean on the yield traits, and to guide the practice of breeding work more effectively, this article in the study of soybean variety resources, ...
