The Differences of Thatch Accumulation by Turfgrass Species

잔디 초종에 따른 Thatch 축적의 차이

The experiment was carried out to analysis the differences between classification by the estimate of survey character and thatch accumulation. The results obtained are summarized as follows:1.BentgrassPenncross: had the highest thatch accumulation. 2.Thatch accumulation of creeping season turf was higher than that of bunch type and thatch accumulation of cool season turf was higher than that of warm season turf. 3.The coverage rate was 43.3%, so turf quality was not good. 4.Bermudagrass(Guymon) had the highest content of lignin in thatch and coverage rate. 5.Species had significant negative correlation with the content of lignin.
