다국어 초록 (Multilingual Abstract)

This study was performed to evaluate the influence of composting process with an intermittent aeration on the variation of rhizosphere soil temperature, CO₂ and NH₃ release, and the growth reponse of tomato plantlet in traditional and composting greenhouse. As the temperature of composting materials increased, rhizosphere soil temperature in 30㎝ depth rose up to 32℃ at one week after introduction. This was 18℃ higher than that of traditional greenhouse. After 20 days of active composting, temperature of rhizosphere soil started to decrease and remained constant at 23℃ after 35 days. For the traditional greenhouse, the averaged temperature ranged at 14∼15℃. This results showed that composting greenhouse had the greater effect on increasing the underground temperature. Average value of evoluted CO₂ from the composting greenhouse for 70 days was 782∼1154ppm. This was 1.7∼2.6 times higher than that of the traditional greenhouse with an average of 440∼462 ppm. NH₃ release was highest during 2∼10 days in intermittent aerated composting and reached to 134 ppm maximum on the 5th day, then decreased rapidly, and maintained at 3∼4 ppm after 17 days. Increased photosynthesis due to the CO₂ gas and a favorable rhizosphere environment due to the increased underground temperature resulted in improved growth, yield, and Brix degree of tomato fruit.
