Abstract

Effect of N and S supply on the growth and organo-sulfur compounds of Zhangqiu spring onion was investigated in a potted soilless experiment.The results indicated the growth and organo-sulfur compounds of spring onion were influenced by N,S and their interactions significantly.N supply promoted plant growth and increased shoot N concentration and uptake,and S supply enhanced shoot S concentration and uptake.Concentration of organo-sulfur compounds decreased with N supply increasing under deficient S condition,and sufficient N and S supply increased organo-sulfur concentration.The highest organo-sulfur concentration(7.23 μmol/g,FW) was observed at N 12.0 mmol/L and SO2-4 4.00 mmol/L,however,excessive N supply(N 24.0 mmol/L) retarded plant growth and decreased concentration of organo-sulfur compounds.Therefore,N could regulate the growth and organo-sulfur compounds of Chinese spring onion with sufficient S supply.
