재배방식과 피복재료가 천마의 수량과 품질에 미치는 영향 = Effect of Yield and Quality for Cultivation Type and Mulching Materials on Gastrodia elata Blume

다국어 초록 (Multilingual Abstract)

This study was compared to outdoor field (OF) and rain shelter greenhouse (RSG) according to cultivation type of Gastrodia elata Blume. Also, the effects of yield and quality for mulching materials in RSG were compared. The yield of G. elata was investigated good merchantable quality, and the quality was investigated hardness, chromaticity, weight loss and the contents of the major functional components. The cultivation of RSG was increased the yield, hardness, gastrodin, and vanillyl alcohol compared to OF, and the weight loss, chromaticity, and ergothioneine were almost equal. Rice straw treatment showed higher than those of the control and other treatments on the yield and hardness. As a result, the yield and the quality of RSG, which can control the soil moisture, were better than that of OF. And the lower the soil moisture content according to the mulching material, the harder the surface and the higher the hardness.

국문 초록 (Abstract)

천마의 수량과 품질 향상을 위하여 비가림시설재배와 노지재배, 비가림시설내 여러 피복재료를 활용하여 천마의 수량 및품질에 미치는 영향을 비교분석하였다. 천마의 수량은 비가림시설이 노지재배에 비해 49% 증수되었다. 또한, 비가림시설재배내에서 피복재료 처리에 따른 천마의 수량성은 무피복에 비해 볏짚피복 44%, 낙엽피복 26%, 차광망피복에서 각각 22% 증수되었다. 천마의 증숙 전․후 색도는 비가림시설재배가 노지재배에 비해 색도 변화가 적었다. 또한, 천마의 경도는 비가림시설재배가 노지재배보다 더 높았고, 비가림시설재배의 증숙 후는 증숙 이전에 비해 17.1%, 노지재배는 29.2% 각각 감소하였다. 증숙 후 무게 감소율의 경우 비가림시설재배는 10.3%, 노지재배는 9.1% 감소하였다. 가스트로딘, 바닐린 알콜은 노지재배보다 비가림시설재배에서 함량이 증가하였고, 에르고티오닌은재배시설에 따른 변화는 없었다. 따라서 환경을 인위적으로 조절이 가능한 비가림시설재배가 노지재배에 비해 천마의 수량과품질이 좋았으며, 피복재료에 따른 품질은 토양수분함량이 낮을수록 표면이 단단해져 경도가 높아지는 경향을 보였다.
