摘　　要：以金乡白皮蒜为材料,采用Hoagland营养液水培方法,探究硫对青蒜生长发育、品质及主要矿质元素吸收的影响。结果表明:硫可显著提高青蒜植株的叶片数、叶长和叶面积;当硫处理浓度为1.50 mmol/L时,叶片中大蒜素含量最高,较不施硫处理增加97.96%;假茎中大蒜素含量以硫浓度为2.25 mmol/L时最高;当营养液中硫处理浓度为2.25 mmol/L时,青蒜叶片和假茎内可溶性糖和维生素C含量最大,可溶性糖比不施硫处理分别增加2.64和0.53个百分点,维生素C含量分别增加14.98%和24.57%;青蒜植株(叶片和假茎)中全氮和全硫含量随着营养液硫浓度的升高而增加,呈显著正相关;全磷和全钾含量以硫浓度为2.25 mmol/L时最高。总之,硫能显著促进青蒜叶片生长,提高青蒜的营养品质,增加矿质元素的积累,营养液硫处理浓度为2.25 mmol/L时各项指标表现最好。Using Hoagland solution, taking the white garlic as the testing cultivar, the experiment was conducted to study the effects of sulfur on the growth and development, quality and mineral elements of garlic sprouts. The results show that the leaf numbers, length and area are significantly increased with the increments of sulfur content in the solution culture. When the sulfur content is 1.50 retool/L, the allicin content in garlic leaves is the highest, which is increased by 97.96% compared to the control; while the alliein content in stem diameters is the highest when the sulfur content is 2.25 mmol/L. When the sulfur content is 2. 25 mmol/L, the soluble sugar and Vc contents in leaves and stem diameters of garlic sprout are increased by 66.59% and 35.14% , 14. 96% and 24.57% , respectively. There are significantly correlations between total nitrogen and total sulfur contents in garlic plants （ leaves and stems） , and the sulfur contents in the nutrient solution. The total phosphorus and total potassium contents in garlic plants are the highest, when the sulfur content is 2.25 mmol/L. In conclusion, the sulfur fertilization could promote the growth of garlic sprouts, improve the quality of garlic sprouts and absorptions of mineral elements, and the best sulfur content is about 2.25 mmol/L.
