摘要：为探讨氮硫互作对大葱植株矿质营养状况的影响，本文采用裂区试验设计，研究了营养液不同氮（N）、硫(S)水平对盆栽沙培大葱生长量及氮(N)、磷(P）、钾（K）、硫(S)吸收分配特性的影响。结果表明，营养液N、S 水平显著影响大葱根、假基及叶片N、P、K、S含量，植株干物质及N、P、K、S的吸收积累量均随营养液N、S水平升高面显著增加，当硫水平超过6.69mmol/L(S4)时，植株干物质量开始降低，对N、P、K、S的吸收积累量也相应下降，虽然S4较S0(0.01mmol/L)处理仍增加显著，但较S1(1.68mmol/L)干物质重量降低了7.97%，对N、P、 K、S的吸收积累量也分别降低了16.37%、10.24%、9.06%、5.77%。营养液N、S水平及其交互效应(Nx×S)对大葱N、P、K、S在不同器官的分配多有显著影响，但硫的影响远不及氮明显。综合分析表明，以营养液氮水平 16.00mmol/L、硫水平为1.68~3.35mmol/L时最有利于改善大葱的矿质营养水平，并促进其干物质的积累。关键词：大葱；矿质营养；吸收；分配

Abstract: Using split plot design, a pot experiment with sand culture was conducted to investigate the effects of nitrogen and sulfur interaction on adsorption of N, P, K and S nutrients in Chinese spring onion under different N and S level. The results showed that the different concentrations of N and S had significant influence on the N, P, K and S contents in each onion organ, With increases of N and S level in the nutrient solution, the dried matter and the uptake of N, P, K and S in plant was significantly raised, and the dried matter decreased when 6. 69 mmol/L of sulfur level was supplied (S4). Though it was significantly higher than the treatment for 0. 01 mmol/L (SO), the dry matter and absorption of N, P, K and S in S4 treatment were lower than that in 1. 68 mmol/L (S1) treatment, and lowered by 7. 97% , 16. 37% , 10. 24% , 9. 06% and 5. 77% respectively. The effects of the N and S levels and their interaction were significant on the N, P, K and S distribution in almost organs of Chinese spring onion, while the response to S level was less sensitive than N level. In conclusion, for improving the mineral nutrition status and the dry matter of Chinese spring onion, the nutrient solution containing N 16. 00 mmol/L and S 1.68-3.35 mmol/L is an optimal choice.
