Abstract

The purpose of this study is to find the suitable putting green maintenance equipment for improving the quality of putting green. This study was carried out to investigate the green speed(i.e., ball roll distance) by different the types of greens mower(between work-behind greens mower and riding greens mower), the types of reel blades(between 9 blades and II blades) and the types of roller(between riding soil sprayer and lightweight roller). Green speed of golf course putting greens is assessed by use of Stimpmeter. The west course of Lakeside Country Club was selected for the case study. The results are summarized as follows; 1. The green speed was faster in 3.8 mm moving height treatment plot using work-behind greens mower than in 3.8 mm moving height treatment plot using riding greens mower right after the moving and even after eight hours had passed, and it was statistically significant at a 95% confidence level. Therefore, work-behind greens mower was judged to be a proper equipment type for the fast green management practice than riding greens mower. 2. The green speed was faster in 3.2 mm mowing height treatment plot using work-behind greens mower equipped with II blades than in 3.2 mm mowing height treatment plot using work-behind greens mower equipped with 9 blades, and this result was statistically significant at a 95% confidence level. Therefore, II-blade was judged to be a proper blade type for the fast green management practice than 9-blade. 3. The difference in green speed (green speed increased after rolling) between a treatment plot mowed at 3.0 mm mowing height with the work-behind greens mower and then rolled a single time with riding soil sprayer and a treatment plot mowed at 3.0 mm mowing height with the work-behind greens mower and then rolled once with lightweight roller was not statistically significant at a 95% confidence level. However, the difference in green speed (green speed decreased after rolling) between two treatment plots measured after eight hours had passed was statistically significant at a 95% confidence level. Therefore, the lightweight roller was judged to be a proper roller type for the fast green management practice than the riding soil sprayer.

본 연구는 골프코스관리자들이 빠른 그린관리를 위한 장비 사용 계획시 참고가 될 수 있는 기초자료를 제공하고자 그린모아 유형(보행식, 승용식)에 따른 그린스피드 차이, 보행식 그린모아에 장착된 회전날 유형(9날, 11날)에 따른 그린스피드 차이 그리고 롤러 유형(승용식 그린정리기, 경량롤러)에 따른 그린스피드 차이를 비교하였다. 그 결과의 요약은 다음과 같았다. 1. 그린모아 유형(보행식, 승용식)에 따른 그린스피드 차이는 깎기 후 바로 그리고 깎기 후 8시간 경과 뒤에도 보행식 그린모아를 사용한 3.8mm 깎기 처리구가 승용식 그린긴아를 사용한 3.8mm 깎기 처리구에 비해 그린스피드가 빠르게 나타났고 이는 95% 유의수준에서 통계적으로 유의한 결과였다. 따라서 보행식 그린모아가 승용식 그린모아에 비해 빠른 그린 관리에 적합한 장비 유형으로 판단되 었다. 2. 그린모아에 장착된 회전날 유형(9날, 11날)에 따른 그린스피드 차이는 11날 장착 보행식 그린모아를 사용한 3.2mrn 깎기 처리구가 9날 장착 보행식 그린모아를 사용한 3.2mm 깎기 처리구에 비해 그린스피드가 빠르게 나타났고 이는 95% 유의수준에서 통계적으로 유의한 결과였다. 따라서, 11날이 9날보다 빠른 그린관리에 적합한 회전날 유형으로 판단되었다. 3. 보행식 그린모아로 3.0mm로 깎기한 다음이어서 승용식 그린정리기로 1회 롤링한 처리구와 보행식 그린모아로 3.0mm로 깎기한 다음 이어서 경량롤러로 1회 롤링한 처리구간의 그린스피드 차이(다짐후 그린스피드 증가효과)는 95% 유의수준에서 통계적으로 유의하지 못했으나 8시간 경과 뒤에 측정한 두 처리구들의 그린스피드의 차이(다짐후 그린스피드 감소효과)는 95% 유의수준에서 통계적으로 유의한 결과를 나타냈다. 따라서, 경량롤러가 승용식 그린정리기 보다 빠른 그린관리에 적합한 롤러유형으로 판단되었다.
