Study Of Turf Renew By Zoysiagrass Overseeding In North Transition Zone

Under the conditions of north climate transition zone, there are hot summer and cold winter, lead to the cool-season turfgrass grow hard in this area, disease and high maintain fee are main trouble. Take Xi'an Yajian Golf international club for example, in 2006 May, We have seminal progress which have no precedent whatever domestic and abroad, use warm-season turfgrass zoysiagrass overseeded cool season turf which established 10 years ago (Poa pratensis L & Lolium perenne) . After the progress, we use Lolium perenne overseeded the turf that established by zoysiagrass in 2007 October. Finally, we built a long green period turf which turn warm-season turfgrass in hot season and turn cool-season turfgrass in cold season can suffer from bad environment of north climate transition zone. In this study, we conclude this:1,Under the conditions of we have no precedent whatever domestic and abroad, Seminal use warm-season turfgrass zoysiagrass overseeded cool season turf which established 8 years ago. Summarize flow, technology, progress of use warm-season turfgrass overseeded cool season turf, and track 2 years half coverage of zoysiagrass, prove the feasibility of overseeding.2,After success of zoysiagrass overseeding, compare all turf maintain spend from 02 to 08, we can conclude that by effects of zoysiagrass strong anti-disease and anti-pest ability, with low water and fertilizer need, the decrease of maintenance fee over 20%. It indicate overseeding's effect for decrease golf turf maintenance fee in north transition zone.
