Abstract
The effect of different Si application on Kentucky bluegrass(Poa pratensis L.) in terms of upgrowth characteristic and resistance to drought was investigated using soil-cultured pot experiment.the results indicated that 0.08g,0.16g SiO2 per kg soil significantly promoted the growth of grass during the seeding with the initial reaped leaf size and yield increased by 32.5% and 28.3%respectively compared with the control.While 0.24g,0.32g SiO2per kg soil restrained the growth of Kentucky Bluegrass during it's period of growth with the yearly yield lower than control by 4.0% and 28.9%respectively.It can be infered that measured Si supplement could enhance the growth,while excessive Si could restrain the growth.Under the menace of drought,supplement of Si reduced the relative panniculus permeability(RPP),increased the relative water content(RWC).which indicated that Si could enhance the resistance to drought of Kentucky Bluegrass.
