Abstract:
In the typical arid region of Lanzhou，effects of special soil amendment(YNEC) on the physiological characteristics of Poa pratensis under salt stress were studied.The results showed that YNEC soil amendment reduced membrane permeability of Poa pratensis leaf and the content of malondialdehyde，increased proline content，and kept the variation of enzyme-recovery-system of Poa Spp.stay at a relatively high level，improved the salt-resistance ability of Poa pratensis.Drawing from the correlation among every physiological indexes，it was the water content that firstly changed，then a series of physiological changes followed including proline content，the activity of SOD and POD.It was suggested that YNEC soil amendment could regulate and reduce salt stress in soil，and improve the adaptability of turfgrass in saline-alkaline land.
