摘要
以“金蒜3号”大蒜为试材．在水培条件下，以0mmol／L为对照，研究了0．5、1．0、1．5、2．0、2．5mmol／L不同磷浓度对青蒜磷含量、生长及品质的影响。结果表明：青蒜叶片和假茎中磷含量随营养液中磷浓度的升高呈显著正相关；青蒜的植株鲜重、株高、假茎长和假茎粗均随磷浓度的升高呈先增大后减小的趋势，至1．5mmol／L处达到最大，比不施磷处理分别提高了84．99％～470．32％、22．20％～83．19％、10．74％～46．95％和70．11％～99．15％；青蒜叶片和假茎中大蒜素、可溶性糖、游离氨基酸和可溶性蛋白质的含量以及叶片中维生素C含量同样在1．5mmol／L处达到最高。表明水培条件下，栽培青蒜的营养液磷浓度以1．5mmol／L最佳。
Taking ＇Jinsuan No. 3＇ as material, under hydroponic condition, five different phosphorus（P） concentrations at 0. 5,1.0,1.5,2. 0, 2. 5 mmol/L were designed, with 0 mmol/L as control, the effects of P in nutrient solution on P content, growth and quality of garlic sprout were studied. The results showed that the P content in leaf and pseudostem were significantly correlated with the increase of P concentrations. The plant fresh weight, plant height, pseudostem length and pseudostem diameter of garlic sprout were increased at first and then decreased with the increase of P concentrations,and these indexes reached the maximum at the 1.5 mmoI/L P concentration,which were increased by 84. 99%- 470. 32%, 22. 20% - 83. 19%, 10. 74% - 46. 95- and 70. 11% - 99. 15% compared to the treatment of 0 mmol/L P concentration. The contents of allicin, soluble sugar, free amino acid and soluble protein in leaf and pseudostem were also the highest at the 1.5 mmol/L P concentration,so was the content of vitamin （2. Thus it could be seen that,the 1.5 mmol/L P concentration was the best treatment to garlic sprout under hydroponic condition.
