Abstract:: Two consecutive years of field experiments were used to study the effect of nitrogen concentration on Sorghum bicolor yield and nutrient accumulation to different nitrogen addition levels: control (CK), low nitrogen (LN), medium nitrogen (MN), high nitrogen (HN). The results indicated that the Sorghum bicolor height, root length, leaf area index, stem diameter, the ground and underground biomass were higher than CK, which showed the sequence: MN > HN > LN > CK, and illustrated that nitrogen addition could promote the growth of Sorghum bicolor, but high nitrogen addition may cause the slight inhibition. Nitrogen concentration promoted Sorghum bicolor chlorophyll, soluble protein and soluble sugar contents, which first increased and then decreased, which suggested that nitrogen concentration could promote the synthesis of chlorophyll. The carbon, nitrogen, phosphorus and potassium accumulation of different parts of Sorghum bicolor had the significantly difference which showed the order: spike > leaf > root, and different parts of the carbon, nitrogen, phosphorus and potassium accumulation decreased in the order: MN > HN > LN > CK, which showed that nitrogen concentration could increase the plant nutrient accumulation. The plant nutrient of Sorghum bicolor first increased and then decreased with nitrogen addition, which suggested that nitrogen concentration could increase the plant nutrient accumulation. Correlation analysis showed that the nitrogen concentration had the significant correlation with plant height, stem diameter, leaf area per plant, dry weight per plant, grain numbers per spike and grain yield, which indicates that nitrogen is closely related to Sorghum bicolor growth, and played an important role in high-yield cultivation.
