| Abstract/Contents: | "At three slope aspects (semi-shading slope EN 40°, sunny slope WS33°, shady slope WN 29°) of hilly area with purple soil, mixed-sown slope-protection turf consisting of Festuca arundinacea, Lolium perenne and Poa pratensis were studied. The dynamics of relative frequency, relative coverage, relative density, important value and relative yield of the turfgrass within 1~5 years after sowing were analyzed, to study the effects of slope aspect and planting years on the degradation rate of the turf. Slope aspect and planting years had significant effects on the degradation rate of important value and total biomass of slope-protection turf, which was mostly affected by planting years, followed by the interaction of planting years and slope orientation, and least affected by slope orientation. The degradation rates of important value and biomass of the three grass species were significantly different among planting years and slope aspect. Effects of slope orientation on degradation rate of important value followed the order of L. perenne > total value > F. arundinacea > P. pratensis, and effects of planting years followed the order of total value > L. perenne > P. pratensis > F. arundinacea, while effects of both slope orientation and planting years on degradation rate of relative biomass followed the order of P. pratensis > L. perenne > total value > iF. arundinacea. Slope aspect and planting years had significant effects on the degenerative performance of the three grass species. The degradation rate of total biomass for L. perenne and P. pratensis was 74.81% and 86.13% in the 2nd year on sunny slope; while iF. arundinacea had 70.16% degradation rate on shady slope in the 4th year.In conclusion, the slope aspect had different effects on the important value and biomass of three turf grass species, such as the fastest degradation rate for P. pratensis and L. perenne in 2~3 years, while in the 4th year for F. arundinacea. Therefore, the corresponding turf planting and maintenance technical measures should be formulated according to the slope orientation." |
