○ 개발된 활착실을 이용한 현장평가회에서 설문조사를 실시한 결과 필요성은 꼭 필요 72%, 필요 28%이었고, 편의성은 매우우수 28%, 우수 41%, 보통 31%으로 나타났으며, 보급 필요성에 대한 질문에는 꼭 필요 34%, 필요 52%로 보통 13%로 조사되었다
○ 현장평가회를 통해 추가로 개선해야 할 사항은 접목모종의 상단에서 인공광의 분포 균형성 확보를 위하여 등갓 각도 조절 및 등 개수 조절 등 필요한 것으로 사료된다.
○ 여름딸기 증발냉각 부분냉방시스템을 개발하였으며 전북 무주 여름딸기 재배농가에 적용한 결과 부분냉방시스템 적용시 관부 온도 3∼4℃, 근권부 온도 2∼3℃를 냉각하였고 총수확량은 무처리구의 수확량과 비교하였을 때 14% 가 증수되었다.

This study were conducted to introduce the technologies to farmers and to find a problem and improvement for early commercialization about newly developed cultivation system for using greenhouse.
We suggested the environmental management for grafted transplants during healing and acclimatization under artificial light in a closed-type transplant production system. Graft-take system was developed using the suggested value. Artificial light designed to investigate from the top of the grafted seedlings, and environmental control was performed using a combined heating and cooling, humidity control room was designed for survival by utilizing ultrasonic humidifier. Performance test results, such as temperature and humidity environment was to be held in an optimum condition. However, the environment was investigated by unstable when switching the cooling and heating.
For the study on the field applicability of a zone heating and cooling system, evaporative cooing system for ever-bearing strawberry and shoot apex tracing heating system for tomato developed previously were applied for veryfying a field applicability. The effects of evaporative cooling system was estimated on the test bed with growing strawberries in hydroponic cultivation from July 15, 2015 to October 31, 2015 in a plastic greenhouse located in Muju Jeollabukdo. Cooling a crown and root zone was carried out from 10 a.m to 6 p.m during daytime, the result of the test showed the cooling effect that the crown temperature of cooling bed was 3∼4℃ lower than that of control bed and the root zone temperature of cooling bed was 2∼3℃ lower than that of control bed and the accumulated yield was 14% higher than that of the control bed. Also, shoot apex tracing heating system for tomato was improved for increasing the field applicability, improved parts of which were combing a hot water pipe and a blowing fan for a heat radiation plastic duct and moving the duct up and down electrically by using winch motor and axis. Improved system was applied to the tomato greenhouse located in Jangam chungcheongnamdo from November 23, 2015 to February 13, 2016, the result of heating test showed that the heating energy saving rate was 32%, compared with control greenhouse customarily used entire enclosed space heating system, the accumulated yield was 4% higher than that of the control greenhouse. Specially, dieases did not occur in shoot apex - tracing heating greenhouse, it was estimated to be because that heat radiation duct could control temperature and humidity of tomato-growing space very precisely and effectively in optimal conditions.
