以金乡白皮蒜为试材，设置5个硅水平（0、0.75、1.50、2.25、3.00mmol·L-1），探讨了硅对水培大蒜根系生长、光合特性及产量的影响。结果表明：在0～3.00mmol·L-1硅浓度范围内，大蒜的根系生长量、植株鲜质量、蒜薹鲜质量、鳞茎鲜质量及根系活力均随硅浓度增加呈先升高后降低的趋势，当硅浓度1.50mmol·L-1时最高；同时叶片中色素含量、净光合速率和气孔导度也随着硅浓度增加呈先升高后降低的趋势，当硅浓度1.50mmol·L-1时最大；蒸腾速率变化趋势则恰好相反，硅浓度1.50mmol·L-1时最低，比不施硅处理降低了17.78%。

‘Jinxiangbaipisuan’ was taken as experiment material investigate the effects of silicon on root growth,photosynthetic characteristics and yield of hydroponics cultured garlic(Allium sativum L.). Five different silicon levels (0,0.75,1.50,2.25,3.00 mmol·L-1) were designed. The results showed that the root system growth,fresh weights of garlic plant,bolt and bulb,and root system activity all rose with the increase of silicon concentration from 0 to 1.50 mmol·L-1,but fell while the silicon content reached 1.50 mmol·L-1. At the same time,the pigment content,net photosynthetic rate and stomatal conductance of leaves also increased first and then decreased with the increase of silicon content from 0 to 3.00 mmol·L-1.They reached the highest when silicon concentration was 1.50 mmol·L-1. While the change trend of transpiration was just the opposite. It reached the minimum value at Si 1.50 mmol·L-1 and was reduced by 17.78% compared with the treatment without silicon.
