Development of Bottom Irrigation System and Management Method for Cultivation of Bonsai

분재(盆栽)의 대량재배(大量栽培)를 위한 관수(灌水)시스템과 관리방법(管理方法)의 개발(開發)

There have been some problems of high labor. low productivity in the existing systems of bonsai cultivation. This study was conducted to cultivate a large quantity of hig-quality bonsai through the development of bottom irrigation system and management method. Bonsai placed on the FRP bed were grown very well by bottom irrigation system compared with direct watering and sprinkler system. It was concluded that bottom irrigation system was possible to reduce considerable manual labor and produce mass production of high-quality bonsai within shorter periods. This research was finally found that the growth was significantly better and earlier production was certain in the vinyl house, had another advantage which could cultivate less cold-resistant species and therefore broadened a range of species selection for market supply. Cultivation techniques by the use of vinyl house and bottom irrigation system developed was quite effective for early production of bonsai as well as for high productive and value added. This project developed a new practical techniques and systems which can make mass and early production of bonsai with high quality through input of less labor. Interest in bonsai is now expanding in landscape horticulture and other fields concerned, and bonsai export of our country is also increasing. Results from this research will make a great contribution to enhancing of bonsai cultivator's competitive position in world markets and to improving of their annual income.

현재 분재재배의 큰 문제점은 높은 노동력에 비해 생산성이 매우 낮은 것이다 본 연구는 관수시스템과 관리방법의 개발로 고품질의 분재를 대량생산하기 위해 실시되었다. FRP분상에서 재배된 분재는 직수관수나 스프링클러 관수에 비해 저변관수시스템에서 생육이 매우 좋았다. 또한 저면관수시스템은 노동력을 크게 줄일 수 있었고 짧은 기간에 대량생산을 할 수 있었다. 또한 비닐하우스내(內)에서 저면관수 시스템의 이용은 조기생산은 물론 고품질의 분재를 생산할 수 있었으며 내한성이 약한 수종들도 겨울재배가 가능하였다. 본 연구는 세계시장을 위한 국가경쟁력에 크게 기여하였을 뿐만 아니라 농가 수익에도 큰 도움을 줄 수 있었다.
