본 연구에서는 일반농가에서 시설내 환경이 불량한 아치형 파이프하우스를 간이시설로 이용하고 있어 시설내 환경이 개선된 간이시설을 개발하여 작물생장반응을 구명코자 톱날형과 개량아치형, 관행아치형의 시설형태와 노지로 구분, 시험을 실시하여 연구결과를 요약하면 다음과 같다. 1. 개량아치형은 관행아치형에 비해 최고 4$^{\circ}C$의 온도가 낮아졌고, 톱날형은 1$^{\circ}C$이상 낮아 시설내 환경이 개선되었다. 2. 지하부 환경에서 관행아치형에 비해 잠열냉각+배수개선 처리는 1.3$^{\circ}C$가 낮고, 배수개선 처리는 0.9$^{\circ}C$가 낮게 나타나 잠열효과를 1$^{\circ}C$이상 보았다. 3. 톱날형은 하우스파이프를 지주겸용으로 설치하여 성력화면에서 가장 우수하였으며 환기를 위한 인력이 필요치 않아 노동력을 절감할 수 있는 시설로 개발되어졌고, 개량아치형은 환기를 위한 노동력은 필요하였으나 하우스파이프를 지주겸용으로 설치하였으므로 관행아치형에 비해 성력화되었다. 4. 토마토 상품과율은 개량아치형이 4,897kg/10a로 가장 많았고 관행아치형이 그 다음 순이었으며 광합성과 직접적인 관계가 되는 엽면적은 톱날형이 다른 형태보다 가장 넓었다. 5. 수량 및 상품성을 높이기 위해서는 환기면적이 넓은 개량아치형이 간이시설로써 적당하였고, 지하부 환경개선 효과는 톱날형의 잠열냉각+배수개선 방법이 좋았으며, 개량아치형과 관행아치형은 배수개선이 효과적이었다. 6. 톱날형, 개량아치형 간이시설은 성력화되고 시설내 환경이 개선되어졌으며, 관행아치형 시설형태를 좀더 발전시켜야 할 것으로 사료된다.

The purpose of this study was to investigate crop growth responses under various rain shelters which were devised to improve the indoor environment in summer season. For developing the proper type of rain shelter, the improved rain shelters with the roof of saw - tooth type(saw-tooth type) and 3 span-arch type(improved arch type) were compared with the conventional one with the roof of single arch type(conventional arch type) and no rain shelter (open field ). The results were summarized as follows ; 1. The air temperature in the improved arch type was 4$^{\circ}C$ and 1$^{\circ}C$ lower than those in the conventional arch type and the saw - tooth type, respectively. 2. The air temperature drop by the evaporative cooling + improved drainage was 1.3$^{\circ}C$ which was 0.9$^{\circ}C$lower than that by the improved drainage only. 3. The effect of labour saving in the saw-tooth type was superior to any other type because its frames were used as props and the labour for ventilation was not needed. 4. The highest marketable yield of tomato was 4,897kg/10a in the improved arch type and the total leaf areas which related to photosynthesis was the largest in the saw - tooth type. 5. The improved arch type was proved to be proper to raise yield potential. The effect of the underground environment treatment on the quality and quantity of vegetable showed to be outstanding in the saw- tooth type with the evaporative cooling + improved drainage, and in the improved and conventional arch type with the trickle improved drainage. 6. In conclusion, the saw - tooth type and the improved arch type were proved to be labour saving rain shelters and the indoor environments in both types were better than that in the conventional arch type.
