Abstract

The addition of Sulfur(S) fertilizer was found in this study to significantly increase crude protein and ash concentrations whilst at the same time decrease the crude fiber concentration in M.sativa in the Beijing region.S concentration increased by 50%-70% compared with the no S application treatment.S application significantly increased potassium(K) and decreased phosphorus and sodium concentrations as well as the N∶ S ratio.Significant positive correlations between S,N and K in the plant were shown to occur.S-containing amino acid(Cry and Met) concentrations were significantly increased by S application,while a negative correlation between S-containing amino acids and other amino acids was observed.S application significantly increased the digestibility of dry matter(DM) and organic matter(OM).There were significant negative correlations between DM and OM digestibility and crude fiber concentration, and positive correlations between DM and OM with both crude protein and ash concentrations.The critical S ranges in M.sativa for the first,second and third clippings were 0.23%-0.38%,0.28%-0.37%和0.28%-0.38%,respectively and the N∶S ratio ranged from 9.0 to 12.8.
