Abstract
[Objective] The effects of fertilizer on quality characters of continuous cropping sweet sorghum stem were studied to overcome continuous cropping obstacle.[Method] The sweet sorghum varieties Sweet 2 was used to study the effects of fertilization on brix and crude protein content of continuous cropping sweet sorghum stem.[Result] Continuous cropping obstacle could reduce forage quality of sweet sorghum.When preceding crop was sweet sorghum,employing continuous cropping fertilizer 600 kg/hm2 adding nitrogen fertilizer 450 kg/hm2,phosphate fertilizer 450 kg/hm2 and potassium fertilizer 150 kg/hm2,brix and the crude protein content of sweet sorghum were the highest.When preceding crop wasn't sweet sorghum,employing phosphate fertilizer 450 kg/hm2 and continuous cropping fertilizer 600 kg/hm2,brix and the crude protein content of sweet sorghum were the highest.[Conclusion] The research could provide essential scientific evidence for overcoming continuous cropping obstacle of sweet sorghum.

Claim · model-written summary
When sweet sorghum was the preceding crop, the fertilizer mix of 600 kg/hm2 continuous-cropping fertilizer with N 450, P 450 and K 150 kg/hm2 gave the highest brix and crude protein content.
