| 摘 要： | 采用田间试验方法,设置1个优化施肥处理和2个习惯施肥处理,分析了大豆不同生育时期各部位可溶性糖积累和分配的特点.结果表明,优化施肥处理通过施用缓释尿素,减少前期的氮肥供应量而增加后期供应量,有效延长叶片功能期,增加光合产物的合成,增加籽粒中的可溶性糖积累量,提高可溶性糖在籽粒中的分配比例,提高产量.

| Abstract: | Field experiment was conducted with three treatments:integrated nutrient management(INM),farmers’ fertilization practice(FFP) 1 and 2.The paper analyzed the soluble sugar accumulation and distribution in various parts of soybeans at different growth stages.The results showed that INM could increase the soluble sugar content in leaves,extend the period of the leaf function,improve the output of the soluble sugar in stems,increase the soluble sugar accumulation in pods,and increase the allocation ratio of soluble sugar in pods and soybean yield. |

| Keywords: | soybean integrated nutrient management soluble sugar distribution yield |
