Abstract

This study was conducted to examine the effect of cool-season grass overseeding on the green period, turf quality and density in zoysiagrass lawn. Treatments were perennial ryegrass (PR) overseeding ($60g\;m^{-2}$) on medium-leaf type zoysiagrass, Kentucky bluegrass (KB) overseeding ($20g\;m^{-2}$) on medium-leaf type zoysiagrass and narrow-leaf type zoysiagrass, and no overseeding on medium-leaf type zoysiagrass. Overseeding of KB or PR effectively provided quality improvement of zoysiagrass lawn by extending green-period about one month in spring and two months in fall season. PR overseeding showed quick green cover within 2-3 weeks but decreased the quality of overseeded zoysiagrass lawn during the summer season. Whereas, KB overseeding showed slow green cover taking two to three month after seeding but provided stable and good turf quality throughout the years. KB or PR overseeding significantly increased the turf density of zoysiagrass lawn except the period of summer depression of PR. The ground coverage of cool-season grasses ranged from 30 to 80% with considerable seasonal variation. As a result, KB and PR have their strengths and weaknesses as an overseeding material. Thus, the use of KB and PR as a mixture would provide better overseeding performance in zoysiagrass lawn.

본 연구는 녹색유지 기간이 6-7개월에 불과한 한국잔디로 조성된 잔디밭에 한지형잔디 종자를 덧파종하여 잔디밭의 녹색기간 연장, 잔디품질, 잔디밀도 등을 평가하기 위하여 수행되었다. 처리내용은 대조구로 한국잔디(중엽형)를 포함하여 퍼레니얼 라이그래스($60g\;m^{-2}$)를 중엽형 한국잔디에 덧파종 처리와 켄터키 블루그래스($20g\;m^{-2}$)를 중엽형과 세엽형 한국잔디 '세밀'에 덧파종 처리를 두어 2014년 부터 2016년까지 조사하였다. 한국잔디에 켄터키 블루그래스 또는 퍼레니얼 라이그래스 덧파종으로 월동 전 2개월, 월동 후 봄철 녹화기에 1개월로 총 3개월 정도의 녹색기간 연장으로 품질유지 효과를 보였다. 퍼레니얼 라이그래스를 덧파종 하였을 때 발아 및 초기생장이 빨라 덧파종 후 2-3주만에 녹색기간 연장효과를 볼 수 있었으나, 고온 다습한 여름철 기간 동안에는 하고현상으로 품질 저하가 나타났다. 이에 반해 켄터키 블루그래스로 덧파종한 경우에는 발아 및 초기 생육이 느려 가을 파종시 당년에 뚜렷한 월동전 녹색기간 연장 효과를 볼 수 없었으나, 이듬해부터는 하절기를 포함하여 연중 안정적인 품질 및 녹색 유지 효과를 보였다. 세엽형 한국잔디에 켄터키 블루그래스 덧파종 처리가 중엽형 잔디 처리에 비해 균일도가 좋아 품질 평가가 높게 나타났다. 덧파종은 퍼레니얼 라이그래스의 하고현상 발생시기를 제외하고는 한국잔디의 잔디밀도를 유의하게 향상시키는 효과를 나타냈다. 덧파종한 한지형잔디의 피복률은 계절과 초종에 따른 변화를 보였고 약 30-80%의 피복률을 나타냈다. 본 시험결과 퍼레니얼 라이그래스는 덧파종 후 빠른 피복도와 뚜렷한 녹색기간 연장효과는 있으나 하절기 품질저하를 보였고, 켄터키 블루그래스 덧파종은 초기 생육은 느리나 연중 안정적인 품질유지가 가능한 특성을 보여 덧파종시 2종을 혼용하여 사용하는 것이 바람직할 것으로 판단되었다.
