마사토가 학교 운동장 피복재료로 많이 사용되어 왔고 일부에서는 천연잔디를 사용해 왔으나 최근에는 인조잔디가 많이 사용되기 시작하고 있으며 서울의 경우 174개교의 운동장에 인조잔디가 설치되었고, 미국에서는 인조잔디를 시공한 곳이 운동장뿐 아니라 공원에 이르기까지 3,500곳 이상이 된다. 이러한 인조잔디 사용의 증가로 인해 인조잔디가 주변 환경에 미치는 영향은 많이 연구된 것에 비해 인조잔디가 주변 미기후에 미치는 영향은 한국에서는 많이 연구되지 않고 있다. 그러므로 본 연구의 목적은 학교 운동장에 시공되는 세가지 포장재료가 - 인조잔디, 천연 잔디 및 마사토 - 각각 주변에 미치는 기온저감 및 열환경 영향을 조사하여 학교운동장 계획에 유용한 정보를 제공하는 데에 있다. 본 연구에서는 전산유체역학기법(Computational Fluid Dynamics, CFD) 시뮬레이션을 이용하여 세 가지 포장재료에서의 기온 및 열쾌적지수(Predicted Mean Vote, PMV) 시뮬레이션 결과를 도출하여 현장 관측 기온 값과 비교하였다. 2011년 7월 20일 14시 30분 주간의 기온 저감효과는 천연잔디가 인조잔디와 마사토포장과 비교하여 가장 높게 나타났다. 야간에도 23시 30분에 기온 저감 효과가 나타났지만 주간보다는 크지 않았다. PMV효과도 역시 천연잔디가 인조잔디와 마사토포장보다 주간보다 크게 나타났으나 야간에는 별 차이가 없었다. 본 연구결과 인조잔디가 기온 저감효과 및 열쾌적성 효과가 가장 낮게 나타나 학교운동장 계획 시 이와 같은 열환경 효과를 고려할 필요가 있다고 판단되었다.

Vehicular traffic on turf results in loss of green cover due to direct tearing of shoots and indirect long-term soil compaction. Protection of turfgrass crowns from wear could increase the ability of turf to recover from heavy traffic. Plastic turfpavers have been installed in trafficked areas to reduce soil compaction and to protect turfgrass crowns from wear. The objectives of this study were to evaluate traffic performance of turfgrasses (Zoysia matrella and Axonopus compressus) and soil mixture (high, medium and low sand mix) combinations on turf-paver complex. The traffic performance of turf and recovery was evaluated based on percent green cover determined by digital image analysis and spectral reflectance responses by NDVI-meter. Bulk density cores indicated significant increase in soil compaction from medium and low sand mixtures compared to high sand mixture. Higher reduction of percent green cover was observed from A. compressus (30-40%) than Z. matrella (10-20%) across soil mixtures. Both turf species displayed higher wear tolerance when established on higher sand (>50% sand) than low sand mixture. Positive turf recovery was also supported by complementary spectral responses. Establishment of Zoysia matrella turf on turfpaver complex using high sand mixture will result in improved wear tolerance.

본 시험은 2003년 9월부터 2005년 12월까지 충남대학교 생명과학대학내 부속 초지시험포장에서 수행하였다. 공시된 혼파초지는 상번초형(tall type) 혼파초지(orchardgrass, Potomac 50+tall fescue, Fawn 20+ Kentucky bluegrass, Kenblue 10+red clover, Kenland 20%)와 잔디형(turf type) 혼파초지(Kentucky bluegrass, Newport 60+Tall fescue, Reboil II 20+ perennial ryegrass, Palmer II 20%}의 두 처리를 두어 시험하였다. 얻어진 시험결과는 다음과 같다. 2년 평균 건물수량은 상번초형 혼파초지가 12,721 kg/ha으로 잔디형 혼파초지의 11,275 kg/ha 보다 높은 결과를 보였다(p<0.05). 잔디형 혼파초지는 상번초형 혼파초지에 비하여 CP 함량과 건물소화율(DMD)이 높은 반면에 NDF와 ADF, cellulose 및 lignin 함량은 낮은 결과를 보였다(p<0.05). 2년 평균 조단백질수량(CPDM)과 가 소화건물수량(DDM)은 상번초형 혼파초지가 잔디형 혼파초지에 비하여 높은 결과를 보였다 (p<0.05). 이상의 결과로 보아, 잔디형 혼파초지는 상번초형 혼파초지에 비하여 목초의 사료가치는 높았으나, 건물수량이 낮아서 조단백질수량과 가소화건물수량이 낮은 결과를 가져왔다. 그러나 잔디형목초는 상번초형 혼파초지에 비하여 사료가치가 높고, 연간 13회 예취 시 수량과 밀도를 고르게 유지할 수 있었던 것으로 보아 추후 말이나 유산양과 같은 가축의 방목이용 가능성을 타진할 필요가 있다고 판단된다.

This experiment was conducted to investigate the effects of turf grass growth to seedling rates and bed soil types. The results of this experiment were summarized as follows; the more increasing the seedling rates, the plant height and leaf length were longer, but the number of leaf and number of branch were fewer. Incase of transplanting of turf grass seedling by rice transplanting machine, it might be considered that the proper alternative bed soil was sandy loam soil with regarding to the economic aspects. The maximum seedling rate of turf grass in the seedling tray for rice was 1,000 of seedling amount due to the nutrient competition with intensive seedling. As the results indicated, it might be recommended that the proper alternative bed soil was sandy loam soil with 1,000 of seedling rates in case of transplanting of turf grass seedling by rice transplanting machine.

School is the center for life of the students, 30% of Korean population. Students spend half of their daily life at school. However, amenity of school is not so good because school grounds in Korea are covered with soil while in USA and Europe with turf. This study was conducted to provide guidelines for constructing natural turf ground at school. 1. As of 1999, number of school grounds covered with turfgrass in Korea is only 130 out of 10,345. More turfs grounds should be constructed to improve amenity of school. Dept. of Education in Japan supports schools to establish turf grounds. 2. In Korea, only Zoysia japonica is used while in Japan several turfgrasses such as Zlysiagrass, bermudagrass and tall fescue are used. 3. In Korea and Japan, turfgrass at school is planted on soil based rootzone system resulting poor quality by heaby traffic. Recently in Japan, sand based rootzone systems such as Califonia and USGA systems are used at the schools with many students. 4. School turf both in Korea and Japan was managed by students and teachers. Turf quality of schools in Korea was not so good due to the poor management.

Winter turfgrass injury is one of the critical problems of many golf courses in Korea. Turfgrass loss from freezing injury due to low temperature leads to many types of damages including weed invasion, increased herbicide cost, increased soil erosion, and expensive re-establishment. Although Kentucky bluegrass (Poa pratensis L.) which is the most widely used among cool-season grasses in Korea is well known as cold tolerance species, freezing injuries to Kentucky bluegrass during winter are often found. Protecting the turfgrass crown is necessary to recover from low temperature stress in winter because shoots and roots can be recovered from the crown. Turf covers may protect the crowns from direct low temperatures and desiccation. Six different turf covers were installed to cover Kentucky bluegrass during a period of low temperatures. Turf covers had positive effects for spring green-up of Kentucky bluegrass based on the study. Applying any type of turf covers on Kentucky bluegrass resulted in an increase average and minimum temperature compared to the uncovered plot. Among turf covers, clear PVC film without holes produced the longest root length and the highest turfgrass quality.

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.

In this study, the distribution of players on a soccer field was investigated with slide -photos in order to suggest a basic data for the athletic turf maintenance and construction. The results of this investigation may be summarized as follows. 1) There's a tendency that trampling frequency per grid (32.23m$^2$)of a soccer field gradually increases from the corner area to the center. Especially the area around goal and center-circle get the highest frequency. 2) Trampling numbers per grid show the similar tendency to trampling fequency. And the grid around the goal get the highest trampling number per grid.(6.52 times/32.23m$^2$). 3) The extent of the damage to the athletic turf per grid also show the similar tendency to the foregoing results. Under such extent of the damage to the athletic turf as these, the method of the turf maintenance and construction will be made.

본 시험은 한국잔디의 실생묘 이식 재배에 따른 적정 이식 시기를 구명하기 위해 수행하였다. 정식시기가 지연됨에 따라 잔디의 생육저하를 초래하였고, 생육특성을 고려할 때, 이식 시기는 7월 초순이전에 하는 것이 좋은 것으로 나타났다. 단일 조건이 지속되는 7월4일 이후부터 정식 묘의 포복 분지경수를 비롯한 마디수, 포복경의 총길이 등에서 급격한 생장 감소 현상을 나타냈다. 특히 제2직립경부터는 포복 분지 경수의 감소를 초래하였다.
