Primary study of appropriate mixed sowing ratio of three cool season turfgrasses in initial growth stage

This experiment studied the impacts of the mixed sowing proportion of Kentucky bluegrass, perennial ryegrass and red fescue on turf quality in field conditions in order to provide practical basis for the mixed sowing of these 3 turf grasses in the northern area of China. The results showed the turf with the lower proportion of Kentucky bluegrass or the higher proportion of red fescue fixed with 20% of perennial ryegrass, had greater density, better texture, more green, smaller underground biomass.The optimal mixed sowing ratio of these three cool-season turfgrasses was Kentucky bluegrass:perennial ryegrass:red fescue=1:2:7 after comprehensive analysis all of the turf quality indices.
