摘　　要：在马铃薯的生长发育过程中,干物质在叶片、地上茎和块茎中的分配随生长发育阶段不同而不同;干物质的积累是形成马铃薯产量的物质基础,以合理的栽培技术措施促进干物质的合理分配才能取得比较好的马铃薯产量。The researching results on the characteristics of dry matter accumulation and distribution for two varieties showed that dry matter accumulation in the growth of potato emerged S-shaped curve.The distribution of dry matter in leaves, stems, and tubers was different in various stages. The accumulation of dry matter in whole plant was basis for yield formation; High yield can be achieved by promoting reasonable distribution of dry matter through cultivation.
