최근들어, 친환경 축산이 중요하게 대두대면서 Silvopastrol system에 대한 관심이 높아져 오고 있다. 초지가 나무와 공존하기 위해선 비음에 강한 목초육종과 혼파조합을 선발하는 것이 필요하다. 이에 본 연구는 준 고랭지 지역에서 차광정도에 따른 목초 혼파조합의 식생변화를 살펴보고 생산량과 품질을 조사하여 비음조건에 가장 적합한 목초의 혼파조합을 선발하기 위해 실시하였다. 차광수준이 높아짐에 따라 모든 혼파조합의 목초수량이 감소하는 결과가 나타

Background : This experiment was conducted to find the right degree of shading to reduce summer months when the death Allium hookeri cultivation in the southern highland in Korea. This experiment was conducted at an altitude of 500m, Jeonbuk Namwon unbong plateau region The soil was tested in phosphatic content was slightly higher so 671 ㎎/㎏ than regular soil. Every soil testing was conducted in sandy soil with good water. The test day highs at 50% shading plots of shading in this period about 6.1℃ lower than the non-shading. The soil temperature is lowered to 1.9℃ at 50% shading plots compared with the non-shading. As a result, Allium hookeri underground quantities produced per 1,682 ㎏ 10a in 50% shading plots. This was a 35% increase compared to the non-shading plots. Allium hookeri is native to the Alpine 4,200m from 1,400m above sea level, near the Himalaya Mountains. Myanmar is known as the National vegetables. Allium hookeri is Allium plants. It flies three flavors, including sweet, spicy, bitter taste. Allium hookeri roots are similar to ginseng roots called as 'three vegetable' This is a randomly named. The in Korea was first introduced in 2006. By 2015, the country has been found to 190㏊, Jeonbuk 35㏊ (18.3%) is growing. Therefore, this study was conducted to introduce the cultivation of plants in the southern highland in Korea. Methods and Results : In order to use this experimental Allium hookeri seedlings were planted in Jeonbuk Sunchang after buying. Allium hookeri cultivation methods put the 3∼4 one eye on the roots. Planting the root length was cut to leave a 3∼5㎝. The planting distance was 40×20㎝. The shielding 35, two months were 50 and 75% by July 1, August 31. The air temperature, soil temperature were investigated in accordance with the changes of light in this experiment. And examined the withering rate, brightness, growth conditions, such as Yield. Conclusion : Test results were as follows. Allium hookeri roots emerged on March 2 during planting 43-68 days. Allium hookeri after shading shoot growth characteristics were as follows. 35% shading and 50% shading was a tendency for the number of leaves increased compared to the non-shading. As a result, flooding was 35% as compared to production per 10a 1,682 ㎏ no light shielding at 50%. Plant analysis leaf mineral contents tended increased nitrogen, phosphate, gallium compared to the non-light cultivation. Mineral contents of the root was nitrogen, potassium is higher in comparison with 75% shading no shading.

This study was conducted to investigate the effect of shading degree and rooting media on the growth of Caragana sinica and Sedum middendorffianum after cutting. In C. sinica, the highest rooting rate was obtained in cuttings planted in horticultural soil (Sunshine Mix #1) and peat moss mixture (peat moss : perlite = 1 : 1, v/v) under one layer of 35% shading and in cuttings planted in kanumatsuchi soil mixture (kanumatsuchi soil : decomposition of granite = 1 : 1, v/v) under non-shading. Whereas, regardless of shading degree, most cuttings of S. middendorffianum rooted in both horticultural soil and peat moss mixture. Cuttings of C. sinica showed the highest root length, 10.4㎝ in kanumatsuchi soil mixture under one layer of 35% shading but the highest fresh and dry weight of roots in kanumatsuchi soil mixture under non-shading. In S. middendorffianum, the highest root length, fresh and dry weight of root were obtained in cuttings planted in horticultural soil under non-shading. With these results, we recommended that cuttings of C. sinica should be propagated in kanumatsuchi soil mixture under non-shading and cuttings of S. middendorffianum in horticultural soil under non-shading.

인삼의 시설생산을 위하여 배지 조성 및 차광 정도를 달리한 환경조건 하에서의 생육특성과 생리활성 변화를 검토하고자 온실 및 실내시험을 수행하였다. 적정한 배지 조합은 차광 정도에 따라 달랐는데 무차광에서는 coco peat 단독, 50% 차광에서는 coco peat와 perlite를 50:50으로 혼합하였을 때, 70% 차광에서는 perlite 단독배지에서 유의적으로 높은 생육을 보였다(P〈0.05). 차광은 엽면적, 엽록소 함량, 근장, 지상부 및 지하부 생체중을 유의적으로 감소시켰다. 총 페놀 함량은 지상부(20.7~23.8 mg·kg-1)보다는 지하부(25.8~28.4 mg·kg-1)에서, 무차광(20.7~25.8 mg·kg-1)보다는 차광(23.7~28.4 mg·kg-1)에서 높게 나타났다. 총 플라보노이드 함량은 지하부(6.9~7.0 mg·kg-1)보다는 지상부에서(17.4~26.8 mg·kg-1), 무차광보다는 차광에서 높게 검출되었다. 반면, DPPH 라디컬 소거능 측정을 통한 항산화성은 추출물 농도가 증가할수록 높은 활성을 보였고, 지하부(24.9~28.7%)보다는 지상부에서(31.1~36.5%), 차광보다는 무차광에서 다소 높은 활성을 보였다. 결론적으로 차광은 비닐하우스 조건하에서 재배된 인삼의 생육과 생리활성에 영향을 미치는 것으로 나타났다.
