摘要
通过磷素水平对不同基因型大豆干物质积累与分配影响的研究表明:施磷量对不同基因型大豆品种植株干物质积累量有较大影响,提高施磷量能增加大豆各器官干物质积累量,但施磷量过高各器官干物质积累反而减少,高蛋白品种和高油品种分别以P10处理和P5处理为最佳施P量。干物质分配开花期以前以叶为主,花期以茎为主,花期后生长中心开始转移到豆荚中。
Phosphorus amount has big influence to dry matler acumulation of different of different soybean varieties. When the phosphorus amounts increased, the dry matter accumulation in all soybean organs can be increased, but if the phosphorus amount is more excessive, the dry matter accumulation all soybean organs is less than that before. High protein variety and high oil variety's the best phosphorus amount are P10 and P5 treatment. Dry matter is mainly accumulated in leaves before flowering is mainly accumulated in stems flowering period, then is transfered in seeds after flowering period.
