摘要: 1979~1982年对两个杂交种亩产千斤水平的干物质积累、分配及其对籽粒产量的影响进行了研究。发现高梁总干物质生产中开花前约占43%,开花后约占57%。籽粒产量主要依赖开花后光合作用的净同化率所同化,开花前提供约12~33%。同时观察到高梁生长后期茎叶干重多有回升。群体生长率的动态变化呈双峰曲线,其消长过程与产量形成关系

Abstract: In 1979~1982,the accumulation and distribution of dry matter and theformation of grain yield at the level of 1,000 jin/mu(7.5 tons/hectare)were investigated for two sorghum hybrids.It was discovered that 43% and 57% of total dry matter derived frompre-anthesis and post-anthesis period respectively.
