Abstract:

Through the study of the effect of different varieties and different densities to yield and sugar content of sweet sorghum, it indicates the following aspects. Firstly, yield and sugar content are significant difference of different varieties. Secondly, yield of same variety is significant difference with different densities, but sugar content is not significant. Thirdly, yield and sugar content are significant difference under the interaction of different varieties and densities, but the effect of interaction to sugar content is lower. Meanwhile, Longtian 6 and Longtian 2 have high yield and sugar content. Their best plant density is 67500 plants/hm2.
