우리나라에서 생산되는 양이 가장 많은 계분부숙퇴비를 벤자민 고무나무에 시용하여 게분부숙퇴비의 사용처와 고무나무의 생육과 품질을 향상 시킬 수 있는 방법을 알아 내기 위하여 시험을 수행한 결과를 보고하고자 한다. 1. 벤자민 고무나무의 생육은 계분 부숙퇴비의 시용량 10%일때 가장 좋았다. 2. 벤자민 고무나무의 양분흡수량은 정식후 일수 가 증가함에 따라 많아 지었는데 성분별로 검토하여 보면 질소 > 칼리 > 석회 > 인산 > 마그네슘의 순으로 많았다. 3. 계분부숙퇴비의 시용량에 따른 양분의 흡수량을 살펴보면 계부숙퇴비 10% 해당량 시용이 가장 많았다. 4. 계분부숙퇴비 시용량이 증가할수록 계분부숙퇴비의 뿌리 발육특성 계분부숙퇴비 10% 해당량 시용이 가장 좋았다.

With architectural technology, a building has been a far dense and close. So the thermal environment of the building has become pleasant, but the quality of indoor air has been degraded. Using synthetic products for construction materials and furniture indoors escalates the concentration of volatile organic compounds(VOCs) at indoor air, threatening the health of the residents. To reduce the concentration of volatile organic compounds at indoor air, many methods are designed, and of late, concern has been increased about the effect of air purification using air purifying plants. Field measurements were performed using Aglaonema brevispathum, Pachira aquatica and Ficus benjamiana, which were verified as air-purifying plants by NASA. The effect of reducing the concentration of air contaminants by plant studied in a full scale mock-up model. The variations of concentration of Benzene, Toluene, Ethylbenzene and Formaldehyde were monitored. In most cases, the effect was excellent in Toluene and formaldehyde in summer.

The objective of this study is to examine the impact of the Phytofiltration system on the improvement of indoor air quality. Measurement was performed in a full-scale mock up model to examine the purification efficiency of air by plants. Seven species of plants, which were recommended by NASA, were used in measurements. Two species of plants that showed outstanding purifying effects were chosen for further measurements. The measurements were performed according to the positions and amounts of plants. Thermal environment, the concentration of Toluene and Formaldehyde were monitored. Ficus Benjamiana and Aglaonema brevispathum were excellent in diluting the concentration of contaminants. The effect of diluting concentration became better as the amount of plants increased. The reducing effect was the best when the plants were placed near window.

This study aims at examining the reduction of indoor air contaminants by plants placed in an indoor space. The effect of reducing the concentration of air contaminants by three species of plants was studied in a full-scale mock-up model. Field measurements were performed using Aglaonema brevispathum, Pachira aquatica and Ficus benjamiana which were verified as air-purifying plants by NASA. Their positions and amount were controlled. Two conditions for the amount of plants(10%, 5%) and positions(sun-shine, scatter) were used in two separate rooms whose dimensions are identical. The concentration of Volatile Organic Compounds(VOCs) was monitored three hours after the plants were placed and three days after the plants were placed. The variations of concentration of Benzene, Toluene, Etylbenzene, Xylene, Stylene and Formaldehyde, which are all known as the major elements of Volatile Organic Compounds were monitored. The more plants were used, the more a reduction of indoor air contaminants occurred. The effect of reducing the concentration of air contaminants increased when the amount of plants increased.
