관상용, 식용 및 약용으로도 이용되는 석죽목 석죽과의 여러해살이풀인 오랑캐장구채는 국내에서는 중부 이북지방의 유용 자생식물로 조경산업에의 이용가치가 크나, 이용성 증대 등을 위한 재배기술은 미흡하다. 지피식물용 재배조건의 구축을 위하여 2017년 7월 31일부터 10월 9일까지 약 10주간 본 연구를 수행하였다. 실험재료로 종자에서 육묘한 유묘를 사용하였으며, 유묘의 소질, 이식조건 및 재배관리에 대한 생육의 영향을 조사하였다. 유묘의 소질로는 162구 트레이에서 cell당 4립씩 파종하여 육묘된 유묘가 초장 및 건물중이 높았고, 특히 4립 파종구는 마디수를 제외한 생육량이 다른 처리구에 비해 유의적으로 큰 차이가 있었다. 경제성을 고려할 때, 상토는 혼합비료(N-P-K) $300-200-200mg{\cdot}L^{-1}$가 첨가된 마사토:피트모스(3:1) 혼용토를 충진한 처리구가 효과적이었다. 또한, 코트비료의 기비처리는 포트당 20알 처리구에서 지하부 생체중이 무거웠으나, 엽면적 등 다른 생육량을 고려할 때 기비하지 않은 처리가 효과적이다. 재배관리에 있어서 차광처리는 습기 등의 환경에 약한 유묘의 특성상 차광하지 않고 배치하는 것이 모든 생육량이 높았다. 이식 후에는 추비처리를 하는 것이 효과적이며, 추비농도는 엽수 등을 고려할 때 $500mg{\cdot}L^{-1}$ hyponex이 적합하였다.

It is true that the industrial development has usually been accompanied with urbanization or centralization of population that has inevitably led to high-rise buildings and densely built-up living area in the cities. While it is badly needed to acquire as much green land within the city limits as possible to compensate for reduced space for recreational purpose in parallel with increasingly urbanized area, the living conditions of plants have become seriously devastated due to shortage of sun light walled-off by high-rise buildings and contaminated environment and air. The shade that is generated by high-rise and compact buildings hinders growth of plants, which makes it urgent to develop native ground cover plant that is strongly viable in the shade. For this purpose, Ligularia stenocephala, best known as greens for Ssam (rice and condiments wrapped in leaves) was cultivated under the 30%, 50%, and 80% shadings and observed to see if there would be any changes in soil conditions, growth of plants and chlorophyll contents depending on the shading rate. The leaf number was 10.8 pieces under the 50% shading and 8.4 under the 30%-shading, 7.7 pieces more than that cultivated under lighting. The leaf width turned out to be excellent from cultivation under the 50%- shading, an evidence indicating its possibility of being cultivated as native ground cover plant in the shade. The live weight of the plants cultivated under the shading increased to 31.63 g, 43.39 g and 19.40 g, respectively, compared to 90.43 g of those in the untreated control plot. The increase in growth of roots was particularly significant with 48.48 g in comparison to 12.33 g under 30% shading cultivation. The chlorophyll synthesis amounted to 46.2 under the 50% shading, showing an increase compared to 41.9 under lighting. The chlorophyll synthesis rather shrank under other shading conditions. The cultivation of Ligularia stenocephala under the 50% shading showed the best condition in growth as native ground cover plant.

갯까치수염은 앵초목 앵초과의 두해살이풀로 지상부가 고사하지 않고, 월동 후 봄까지 뚜렷한 윤기가 흐르는 잎을 가지며, 7~8월에 흰색 꽃이 피는 관상성이 뛰어난 우리나라의 자원식물이다. 이에 신 관상소재로서의 품목개발을 위해 관상 및 조경산업용 가치가 큰 갯까치수염의 지피용 작물로서의 재배효과를 확인하기 위하여 2017년 7월 31일부터 10월 9일까지 약10주간 실험하였다. 이식묘의 소질별 생육효과, 기비의 시비와 혼합상토의 조성 및 포트의 크기 등의 이식조건, 차광처리 및 추비시비 등 재배관리에 대한 효과를 조사하였다. 종자로 육묘한 이식묘의 소질로서는 200구 트레이에서 한 cell 당 2립씩 파종된 유묘가 지피용 갯까치수염의 재배에 적합하였다. 이식조건으로 코트비료의 기비는 하지 않고, 마사토:피트모스(3:1) 혼합 용토에 $300-200-200mg{\cdot}L^{-1}$(N-P-K)의 비료분을 첨가한 토양을 충진한 4인치 포트에 이식하는 것이 생육에 가장 효과적이었다. 재배관리에는 차광처리를 하지 않고 배치하는 것이 50 및 70% 차광처리보다 초장, 엽수, 엽면적, 생체중 및 건물중 등 생육에 효과적이었다. 또한, $500mg{\cdot}L^{-1}$ hyponex 추비처리를 한 것의 엽수가 36매로 다른 처리의 15~26매 보다 많았지만, 엽면적 및 생체중을 고려할 때 지피식물로서 10주간의 재배를 위해서는 추비하지 않는 것이 적합할 것으로 생각된다.

Sedum takesimenses among the Korean Native Genus Sedum was selected as evergreen ground covers during winter in the central districts of Korea. In order to obtain basic information for production as a pot flower with good quality, the effects of pinching frequencies on growth and flowering of S. takesimense were investigated. S. takesimense plant height became much shorter and numbers of lateral shoots were increased with increased pinching. Shoots of S. takesimense treated with 30% pinching during 2004 and 2005 showed greater length and less number of lateral shoots than those with 60% pinching. Leaves of S. takesimense treated with 70% shading showed a dark green color and had a longer shoot length and a lower number of shoots than cultivation under full sunlight. Therefore, Korean native S. takesimense will be utilized as ground cover treated with 70% shading or under a tree. Therefore, S. takesimense will be promising as ground cover materials in the central districts of Korea.

With the purpose of designing companion planting of groundcover plants for ornamental uses, this study identified the yearly growth characteristics of nine species of different life forms, analyzed the coverage characteristics of individual plants, and suggested combinations of plants suitable for each life form. Polygonatum odoratum var. pluriflorum, Liriope platyphylla and Hosta capitata, as short-grained plants that can grow to more than 20 cm, tended to grow for 60 days after planting in April and maintain their shape thereafter. Their aerial parts started to wither and enter dormancy after September. Saxifraga stolonifera, Dianthus chinensis and Sedum middendorffianum tended to continuously grow until September after planting in April and their growth declined after September. Lysimachia nummularia, as a creeping plant that grows creeping on the ground, started to show a rapid growth three months after planting. Sedum sarmentosum grew slowly until August and the aerial parts started to wither from September when the temperature decreases. The coverage characteristics of these nine species that grow differently after companion planting were surveyed and the growth of Sedum sarmentosum showed the highest number of companions. It was found that Hosta capitata can be companion planted with Sedum middendorffianum, Saxifraga stolonifera, and Lysimachia nummularia. These results indicate that among different shoot growth types species propagated with their stems creeping on the ground or those that can grow vegetatively with non-rhizome parts are more suitable for companion planting with others than those of which rhizomes branch.

Three evergreen ground-cover species were tested and evaluated for cold acclimation with different lights in central Korea to enrich the varieties of ground cover plants for over-wintering. Nandina domestica which recently started to be planted in central Korea had high chlorophyll unit with shade condition in both locations, Banpo and Gwacheon during winter. Light condition had no influence on chlorophyll unit in Banpo after April, meanwhile full sun condition decreased chlorophyll unit significantly in Gwacheon, which is exposed to cold wind from north. Ophiopogon japonicas had more than double chlorophyll unit in shade condition compared to that in full light condition in both investigation areas in February. In addition, higher value of L and b in shade condition had been maintained than in full sun condition throughout investigation period. However, leaves in Gwacheon were de-colorized in full sun condition after over-wintering. Pachysandra terminalis had more higher chlorophyll unit in shade condition compared to in full sun condition in both investigation areas in February. But light conditions had not effect the difference of chlorophyll unit of Gwacheon in April. Therefore, The present results suggest that evergreen ground covers with shade condition would be used as landscape materials in the capital area.

The aim of this research was carried out that leafty and tonic vegetable using garlic (Allium victorialis L. var. platyphyllum Makino) makes use of landscape ground-cover plant. Following shading level treatments (30%, 50%, 80%), garlic was cultivated to investigate plant growth characteristic and chlorophyll content. Leaf number of all treatments was unaffected, and 80% shading treatment had grown vigorous growth 16.8 cm leaf length and 10.1 cm leaf width compared to 13.4 cm leaf length and 7.3 cm leaf width for the non-shading treatment. Fresh weight of non-shading treatment was better than those of three shading treatments, however, 80% shading treatment had produced 10.4 g fresh weight of stem part compared to 8.5 g for the for the non-shading treatment. The chlorophyll content of the 50 and 80 shading treatments showed 42.8% and 40.5% respectively. These treatments increased 36.7% chlorophyll content compared to non-shading treatments. Following shading level treatments, growth characteristics of garlic in 80 shading level treatment shows outstanding growth and it is worthy of planting as shading ground-cover plants.

This paper has attempted to investigate the change in soil moisture volume and temperature of architecture by planting ground(soil thickness and soil mixture ratio) and ground cover plants(Sedum sarmentosum, Zoysia japonica, Chrysanthemum zawadskii) for middle region green roof system. For this, a test was conducted on the roof of Konkuk University building from April 2009 to October 2009. In terms of treatment, five types(SL, $P_7P_1L_2$, $P_6P_2L_2$, $P_5P_3L_2$, $P_4P_4L_2$) depending on soil mixture ratio and two types(15cm, 25cm) by soil depth were created. Results of soil moisture volume by soil mixture ratio in the 15cm soil thickness showed that the difference was significance between simple soil and mixture soil treatment, however, the statistical significance was not recognized according to soil mixture ratio. In case of 25cm soil thickness, soil moisture volume by soil mixture ratio was more higher 7Vol.%~10Vol.% in the mixture soil than simple soil treatment. In terms of districts planted ground cover plants, soil volume moisture differed among plants in the order Zoysia japonica 17.74 Vol.%$34.86^{\circ}C$, district non-planted $27.49^{\circ}C$, Sedum sarmentosum $25.11^{\circ}C$, Chrysanthemum zawadskii $23.08^{\circ}C$, Zoysia japonica $24.45^{\circ}C$ respectively So, concrete surface showed more higher $5^{\circ}C{\sim}15^{\circ}C$ than other things among the all the time. Result of inner temperature of the architecture and soil, it was measured inner of architecture $25.69^{\circ}C$, inner district non-planted $24.29^{\circ}C$, Chrysanthemum zawadskii $23.90^{\circ}C$, Zoysia japonica $24.02^{\circ}C$, Sedum sarmentosum $25.13^{\circ}C$, respectively.
