摘要：【目的】硫是植物必需的营养元素之一，研究无土裁培营养液中不同浓度硫对韭菜生长和品质的影响，以期为确定合理的韭菜水培营养液配方提供依据。【方法】试验采用水培方法，以含硫2mmol/L的日本千叶农试葱营养液（通用型）为基础，以硫酸钠作为硫源，设置了硫浓度分别为1、2、3、4、5mmol/L的5个处理(分别用S1、S2、S3、S4和S5表示)。鉴于相对低浓度的Na'对植物生长发育影响较小，本试验结果忽略Na 的影响。在非菜第二茬收获时测定了生长、生理、产量、品质指标及含硫化合物的种类和浓度。【结果】适当增加硫素浓度，对韭菜生长有良好的促进作用。与S1处理相比，S2处理非菜的株高、叶长、假茎粗、叶宽和叶片数分别增加了2.6%、4.5%、5.6%、10.8%、7.2%，韭菜单株鲜重和干重分别提高6.9%、10.1%。韭菜根系活力以S3处理最高，比S1处理显著增加了25.7%，叶绿索a和叶绿素a+b与S2处理差异不显著，但显著高

Abstract: [ Objectives ] Sulphur supply affects the yield and quality of Chinese chives. Study of the suitable sulfur concentrations in nutrient solution will provide basis for the optimization of nutrient solution for the hydroponic production of Chinese chives.【 Methods A Chinese chive hydroponic experiment was conducted using the Japan Chiba farming vegetable nutrient solution as base solution. Five levels of sulphur concentrations(1, 2, 3, 4, 5 mmol/L, noted as S1, S2, S3, S4 and S5, respectively) were setup with sodium sulfate as S source The growth, yield, quality and sulfur compounds of chive were measured. [ Results 】 Sulphur was found effective to stimulate the growth of chives. Compared with S1 treatment, the plant height, leaf length, stem diameter, leaf width, leaf number, single plant fresh weight and dry weight of S2 treatment were significantly incrcased by 2.6%, 4.5%, 5.6%, 10.8%, 7.2%, 6.9% and 10.1%, respectively. The peak root activity index was obtained in S3 treatment, which was 25.7% higher than the root activity index of S1 treatment, and the maximum chlorophyll a and chlorophyll a+b contents were obtained in S3 treatment, they were respectively 19.0% and
