【Abstract】 In order to investigate the characteristics of nitrogen accumulation and translocation, two soybean varieties with different protein contents were used in pot experiments. The results show that both the nitrogen accumulation and nitrogen translocation efficiency of higher protein content variety are significantly higher than that of lower-protein variety, there is also great difference between leaf nitrogen and stem nitrogen in high-protein variety, and the former is higher than that of latter, but there is only slight difference in lower-protein one. Nitrogen accumulation peak is ten days delayed in high-protein variety than that of lower-protein one.更多还原
