大豆各生育阶段所需要的日数,通常随品种和栽培环境而有所不同。但就各生育阶段日数对子实产量的关系来说,还不十分清楚。因此,明确大豆整个生育过程中,对子实产量最有影响的生育段阶,这对于大豆栽培和育种工作,将是非常有益的。本试验主要是探讨各生育阶段所需日数和产量之间的关系。
The number of days needed for each stage of soybean production varies, depending on the variety and cultivation environment. However, it is not yet clear enough about the relationship between the number of days at each stage of birth and the quantity of live births. Therefore, it is very beneficial for the cultivation and breeding of soybean to clarify the most important stages of the growth stages that affect the whole fruit production during the whole growing process of soybean. This experiment is mainly to explore the relationship between the number of days required and the yield of each stage of fertility.
