以章丘大葱为材料,并以珍珠岩为栽培基质,采用盆栽试验研究了不同氮、硫供应水平对大葱营养生长前期的于物质累积及含硫有机物含量的影响.结果表明,氮、硫供应及其交互作用显著影响大葱生长和含硫有机物含量.在硫不足(SO2-4 0.01 mmol/L)和硫充足(SO2-4-4.00 mmol/L)供应条件下,随氮供应水平提高,大葱植株干物重明显增加,当供氮水平为N 6.0 mmol/L时,植株干物重及吸硫量达到最大;增加硫素供应可显著提高植株的硫含量和总硫量.然而,硫供应不足时,随着供氮水平提高,植株含硫有机物含量逐渐下降;反之,充足供硫条件下,随着氮供应水平的提高,大葱含硫有机物含量出现先增加后降低.当供氮水平为N 12.0 mmol/L时,含硫有机物含量最高,达到7.23 μmol/g,FW.过量氮供应(N 24.0 mmol/L)则抑制植株生长,降低含硫有机物含量.因此,充足供硫条件下,氮素调控水平对保证大葱高产和高含硫有机物含量至关重要.

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 influ-enced 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 de-creased with N supply increasing under deficient S condition, and sufficient N and S supply increased organo-sulfur con-centration. 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.
