摘　　要：为明确氮硫互作对青蒜(蒜苗)大蒜素含量和品质的影响,以陕西大蒜主栽品种G025为试材,采用2因子3水平随机区组试验设计,于4~5叶期叶面喷施不同浓度氮硫,10 d和20 d后分别采收分析蒜苗品质。结果表明,不同氮、硫浓度及其互作对蒜苗生长及大蒜素、蒜氨酸、硫含量等营养品质都有显著性影响,处理后20 d蒜苗大蒜素、蒜氨酸含量高于处理后10 d,处理后20 d低氮(450 mg·L^(-1))与中硫(300 mg·L^(-1))组合可显著提高叶片和假茎大蒜素含量,高氮(850 mg·L^(-1))与低硫(100 mg·L^(-1))组合或低氮(450 mg·L^(-1))与低硫(100 mg·L^(-1))组合可显著提高蒜氨酸含量。In order to clarify the effect of nitrogen and sulfur interaction on allicin and quality of garlic seedling,a main garlic cultivar‘G025’of Shaanxi was used as test material,and a 2 factors 3 level random block test was designed.This experiment sprayed the leaf surface with different nitrogen and sulfur concentrations during the 4-5 leaf stages,and harvested and analyzed the quality of garlic seedlings after 10 days and 20 days,respectively.The results showed that nitrogen and sulfur factors and their interaction had significant effects on the growth of garlic seedlings,and contents of allicin,alliin,sulfur etc.nutritional qualities.20 days after treatment the allicin and alliin contents of garlic seedlings were higher than that of 10 days after treatment.20 days after treatment,the combination of low nitrogen(450 mg·L^(-1))and medium sulfur(300 mg·L^(-1))could significantly increase the contents of allicin in leaves and pseudostems.The combinations of high nitrogen(850 mg·L^(-1))and low sulfur(100 mg·L^(-1)),or low nitrogen(450 mg·L^(-1))and low sulfur(100 mg·L^(-1))could significantly improve the content of alliin.
