摘　　要：为了优化甜高粱栽培措施,达到高产的目的,通过L9(34)正交试验对内蒙古林西地区甜高粱秸秆产量、籽粒产量、秸秆平均锤度与种肥、密度间之间关系的研究。结果表明:密度是影响甜高粱秸秆产量、籽粒产量和秸秆平均锤度的主要因素。在内蒙古林西地区,甜高粱高产优化栽培技术措施为:尿素8.8kg/667m2、二胺6.2kg/667m2、硫酸钾10.6kg/667m2、密度6000株/hm2。In order to achieve a high-yield of sweet sorghum through optimizing the cultivation measures, the relationships between straw yield, grain yield, the average straw Brix, seed manure and density of that in Lin xi area, Inner Mongolia were studied by the L9（34） orthogonal experiment. The results showed： the production of sweet sorghum stalks, grain yield and average straw Brix were mainly affected by density. The cultivation measures in Lin xi area in Inner Mongolia were optimized as follow： urea 8.8 kg/667m2, diamidogen 6.2 kg/667m2, potassium sulfate 10.6 kg/667mz and 6000 plants/hmz of density.
