초록
석탄 화력발전소에서 생산되는 석탄회를 비료자원 및 토양 개량제로 활용하기 위한 기초자료를 얻기 위해서 배추를 공시작물로 하여 석탄회(유연탄회, 무연탄회)를 수준별(5%, 10%, 15%)로 시용하고 배추의 생육 및 수량, 식물체중 무기성분 함량, 토양의 이화학적 성질에 미치는 영향 등을 조사한 결과를 요약하면 다음과 같다. 1. 석탄회의 화학적 조성은 알칼리성 물질로서 규소와 알루미늄을 75%(
The effect of Bituminous and Anthracite coal ash(fly ash) on the performance of Chinese cabbage on an acid soil was studied through a pot experiment. The levels of application of the materials tested were five, 10 and 15% of dry soil weight. Regardless of the kind of fly ash, the application of it, tended to increase the yield of Chinese cabbage by 13 to 24% in fresh weight. Difference in application levels did not result in the difference in increasing the yield of Chinese cabbage. The application of fly ash tended to lower the all of the mineral nutrient contents in the Chinese cabbage, excepting boron. Boron content tended to increase along with the application of fly ash. Bituminous ash raised the pH of soil and increased available P, exchangeable Ca and soluble boron in the soil remarkably. Anthracite ash, on the other hand, did not increase the contents of other components in the soil, than soluble born.
