摘    要:麦套花生,苗期生长慢、时间长,开花、下针、幼果形成集中,具有较长的产量形成期;主茎高度、总干物质和荚果干重增长规律符合“S”型生长曲线,可用Logistic方程y=k/(1十Ae-Bx)很好拟合;叶面积消长动态符合一元二次方程变化曲线;总干物质积累速率高峰在结荚期(播种后81天),荚果干重增长速率高峰在播种后95天,整个产量形成期内荚果干重日增量都保持较高水平,后期不早衰,且具有较高的分配系数。

关 键 词:花生,麦套,生长发育,干物质

Abstract:Summer peanut interplanted in wheat grew slowly in seedling stage, but bloomed in a relatively short period and the genophores and young pods formed fast. The increasing dynamics of main stem height dry matter and pod weight accorded with the sigmoid growth curves,and was fitted to the Longistic equation. The dynamics of leaf area accorded with the curves of second-order equation. The cumulative peak of dry matter occurred at pod setting stage(81 days after planting),and the increasing peak of pod weight occurred at 95 days after planting. Summer peanut interplanted in wheat maintained a higher increasing rate per day of pod dry weight and a higher coefficient of dry matter distribution in whole yield forming phase,and did not devitalize early in latter phase.
Keywords:Peanut interplanted in wheat  Growth and development  Dry matter
