Abstract

This article presents an effect of deicer such as $CaCl_2$(calcium chloride) and EFD(Eco-Friendly Deicer) composed by organic acids on the survival and growth of plant. Pine and bush clover which are main natural species on the road side, and young radish and kidney bean which are cultivation species used in this test that responses of survival and growth were analyzed as grade concentration of deicers. Bush clover showed the most sensitive survival response among 4 species to the deicer. Pine growth didn't have statistical significance as the kind of deicers and concentration variation, but growths of bush clover and kidney bean showed growth inhibition in concentration more than 3% of $CaCl_2$ and EFD1. The results of survival and growth for $CaCl_2$(calcium chloride) demonstrated that young radish and pine are tolerant species and bush clover and kidney bean are sensitive species. Although EFD1 manufactured by chemical showed the negative effect on the survival and growth of plants, EFD2 made with waste compost was confirmed that it has the positive influence to the survival and growth of the both sensitive and tolerant plant species for chloride.

기존 제설제인 염화칼슘($CaCl_2$)과 유기산 제설제 EFD(Eco-Fridendly Deicer)가 식물의 생존과 생장에 미치는 영향을 파악하였다. 도로주변의 주요 자생종인 소나무와 참싸리 그리고, 재배종인 열무와 강낭콩 유식물에 대하여 제설제의 농도 구배에 따른 생존과 생장반응을 분석하였다. 네 종중에서 참싸리는 제설제에 가장 민감한 생존반응을 보였다. 소나무의 생장은 제설제 종류와 농도변화에 통계적 유의성을 보이지 않았다. 참싸리와 강낭콩의 경우는 $CaCl_2$와 EFD1의 3%이상의 농도에 생장저해를 보였으나, EFD2에 대해서는 생장이 양호했다. $CaCl_2$에 대한 생존 및 생장반응으로 확인된 염에 대한 내성이 있는 식물은 열무와 소나무이었고, 민감한 식물은 참싸리와 강낭콩이었다. 화학약품으로 제조한 EFD1은 식물생장의 저해영향이 컸지만, 음식물쓰레기를 활용한 EFD2는 염에 내성이 약한 식물들에게도 생존 및 생장의 피해가 적음을 확인하였다.
