Raising medium function of environmental engineering by usinglife rubbish to produce carpet turf

Abundant material with low cost was utilized to raise medium function of producing carpet tutfby life rubbish. The results showed that the material used could strikingly raise water retentiveness and ventilating of medium. Through the determination of the effect of each growth index of several turfgrass, emergence density, plant height, root growth and individual plant's net primary production were all positively related to the materials amount mixed, showing that the mixture of material could promote turfgrass growth, further proving that the material used raised medium function of producing carpet turf by life rubbish and made most use of life rubbish resources. It provided a scientific base is for application of environmental engineering by using life rubbish to producecarpet turf. So the study had both important theoretic meaning and applied value.
