摘　　要：气候条件和栽培管理技术直接影响着高梁的干物质积累状况和最终产量。在栽培技术基本相同条件下,干物质的积累主要受气候条件所制约。因此。Based on field studies, the relationships between climatic conditions and annual yields of sorghum in Jilin province are analyzed. Different types of bumper, medium and short harvest years are classified using fuzzy subordination, and dynamic models of dry matter accumulation in different harvest years are established, which contributes to the scientific prediction of sorghum yield in years with different climatic conditions.
