摘　　要：甜高粱是人类开发生物质能的重点。近年来对甜高粱品种的研究较多,对配套的栽培技术研究较少,使品种的增产作用没能充分发挥。通过甜高粱不同品种及不同栽培密度对产量和含糖量的影响研究,阐明甜高粱不同品种的产量和含糖量有极显著差异;同一品种不同栽培密度间的产量差异极显著,含糖量差异不显著;品种与不同栽培密度互作间的产量和含糖量差异显著,但互作效应对含糖量的影响较低。同时阐明,龙甜6和龙甜2产量高,含糖量高,在生产上采用的最佳栽培密度为67500株/hm2。Through the study of the effect of different varieties and different densities to yield and sugar content of sweet sorghum, it indicated the following aspects. Firstly, yield and sugar content were significant difference of different varieties. Secondly, yield of same variety was significant difference with different densities, but sugar content was not significant. Thirdly, yield and sugar content were significant difference under the interaction of different varieties and densities, but the effect of interaction to sugar content was lower. Meanwhile, plants/hm2.
