Abstract：'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.
