Abstract: Festuca arundinacea L. was planted in municipal solid waste (MSW) compost which was leached by different amount of water. Seed germination and physio-ecological indices were investigated. The results showed that F.arundinacea in the leached compost was better than in the control(pure compost without leaching) through the growth index. In the treatment of 1∶1 leaching proportion, the maximum germination rate increased 89.6% as compared with the control. The determination of the activity of protective enzymes(SOD, POD, CAT), the content of proline and the accumulation of MDA indicated that the stress of compost after leaching was less than pure compost without leaching, and the leached compost was more favorable for turf growth. Considering of growth and physiological indices of F.arundinacea, the optimum proportion for compost leaching was the mass ratio of water to compost=2∶1.
