摘　　要：通过对甜高粱不同品种不同施肥方式产量和含糖量的影响研究,阐明不同甜高粱品种的产量性状和含糖量差异极显著;同一品种采用不同施肥方式产量的差异极显著,但含糖量差异不显著;不同品种与不同施肥方式互作对产量和含糖量的影响差异不显著。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施肥方式为7月5日一次性追施磷酸二铵150kg/hm2,尿素150kg/hm2,硫酸钾150kg/hm2。Through the study of the effect of different varieties and fertilizer application methods 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 fertilizer application methods, but sugar content is not different. Thirdly, yield and sugar content are significant difference under the interaction of different varieties and fertilizer application methods. Meanwhile, Longtian 6 and Longtian 2 have high yield and sugar content. Their best fertilizer application method is ammonium phosphate 150 kg/hm2 , urea 150 kg/ hm2, and potassium sulphate 150kg/hm2 in one sump sum on July 5.
