| 中文摘要 | 本省之氣候類型較適於暖季型草類( warm-season turfgrasses )生長,但因於 冬季時有寒流發生,氣溫降低,此類草種不耐寒冷而造成冬季草坪品質不佳。為改善此一現 象, 本實驗利用三種不同冷季型草類( cool-season turfgrasses )(粗莖藍草、小糠草 、 肯塔基藍草)於冬季進行交播( overseeding )操作於百慕達草果嶺之上並與無交播作 業區對照,以期改善此一現象,並經由實地管理操作,以瞭解各冷季型草種於此地表現之特 性。由實驗結果顯示:四個處理間平均每週收刈鮮草重交播處理者雖稍有增加但差異不顯著 ,此可能由於本試驗期適逢暖冬,而使百慕達草並未受嚴重寒害之故,而鮮草重的差異不大 亦顯示其他各冷季型草類於此時期成長亦甚好。草色之表現以未交播之百慕達草較偏深綠, 各冷季型草種色澤較淺。平滑度測試結果以未交播處理及粗莖藍草與百慕達交播處理者最佳 ,而肯塔基藍草與百慕達交播處理最差。 然而回春( spring up )之表現以小糠草和肯塔 基藍草與百慕達交播之處理速度最快,而以粗莖藍草與百慕達交播之處理較緩慢。上述結果 顯示三種冷季型草類於本省冬季生長無礙,於寒冬時交播操作應屬可行。 |
| 英文摘要 | Warm-season turfgrasses are well adapted to the climate conditions in Taiwan. However, during the winter period, when low temperatures persist, the turfgrass showed lower turf qualities due to chilling injury. In this experiment overseeding operations were conducted by using three different types of cool-season turfgrasses (rough bluegrass, bentgrass, and Kentucky bluegrass) on bermudagrass green to see if the operations can improve turf quality during the winter period. Also, through management practices the adaptation performance of these turfgrasses were evaluated after overseeding. The results showed that the average fresh weight of the mowed turf was slightly higher for the overseeded treatments as compared to the check in the early stage of the winter. However, no significant differences of the mowed fresh weight were found among all treatments in the rest of the period due to the mild winter. Also, the check treatment showed darker green color compared to the overseeded treatments. The check and overseeded with rough bluegrass treatment showed better smoothness test results than the Kentucky bluegrass treatment. The spring up rate were faster in bentgrass and Kentucky bluegrass treatments than in the rough bluegrass. Above results showed that even in this mild winter the three cool-season turfgrasses were well adapted to the winter climate here in Taiwan. Thus, with proper operation and management practices the overseeding operation provides another option for winter turf. |
