Abstract

생활하수슬러지를 장미 재배지에 토양 개량제로서 시용량을 달리하여 첨가하고 장미 생육상, 토양 및 식물체중 중금속의 함량에 미치는 영향을 조사하였다. 장미 재배지에 하수슬러지를 사용하면 시용량이 증가함에 따라 신장과 비대생장이 증가했으며 주당 꽃송이도 많아 생육이 양호한 것으로 나타났다. 토양 중 중금속 함량은 시용량의 증가에 따라 일정한 경향은 없었으며 식물체에 의한 대부분 무기성분 흡수량은 하수 슬러지의 시용량에 따라 증가하는 것으로 나타났다. 결과적으로 생활 하수 슬러지는 유해물질의 농도가 낮으면 경작지에 처리하여도 무관할 것으로 판단된다. This study was conducted to find out the effect of municipal sewage sludge on the growth and heavy metal content of rose and soil chemical properties. Municipal sewage sludge was applied to soil at rate of 0, 3, 5, 10 and 15 ton/10a, the plant height, flower number and stem size of rose were found to be increase in the treatments of sewage sludge. Contents of mineral nutrients in rose stem were determined to be higher at municipal sewage sludge application plots than those of no application. But, there were not any significant increases of heavy metal contents in soil and rose stem with the sludge applications. from the results of this study, it is apparent that the application of municipal sewage sludge would not increase available heavy metals in soil.
