Abstract

This experiment was conducted to select winter-adaptable crop system or cropping systems for an enhanced carbon (C) fixation amount in plant biomass and soil. Single or mixed cropping systems of green manure crops, rye (R), triticale (TC), hairy vetch (HV), TC+HV, and control (fallow) were investigated during winter and spring. The amount and content of C and N in the above-ground biomass and soil C content by soil depth were measured under different green manure crops. The above-ground biomass was highest in TC+HV followed by R and TC with 664, 585, and 545 kg $10a^{-1}$, which exceeded the biomass of control by 181, 160, and 149%, respectively. The amount of C accumulation was higher in soil surface than deep soil. which was a similar pattern to the above-ground biomass. Therefore, green manure cropping in winter and spring seasons will be very helpful of improve soil organic matter.

본 연구는 국내에서 대표적으로 이루어지고 있는 녹비작물인 호밀, 트리티케일, 헤어리베치 단파와 트리티케일+헤어리베치 혼파를 대상으로 온실가스인 이산화탄소 저감을 위한 최적의 녹비작물을 선발 하기위하여 수행되었다. 윤작지 녹비작물의 지상부 바이오메스는 트리티케일+헤어리베치 664 kg $10a^{-1}$, 호밀 585 kg $10a^{-1}$, 트리티케일 545 kg $10a^{-1}$이었으며 대조구 대비 트리티케일+헤어리베치 181%, 호밀 160%, 트리티케일 149% 증가하는 경향을 보였다. 녹비작물 재배시기 동안 표토의 유기물 함량이 심토보다 높은 경향을 보였다. 토양 유기물 함량은 호밀 처리구에서 가장 높았고 그 다음이 트리티케일+헤어리베치 순으로 나타났다. 지상부 바이오메스 생산량이 많은 호밀, 트리티케일+헤어리베치 재배구에서 가장 높은 유기물 함량을 보인 것은 탄소함량과 C/N율 때문인 것으로 분석 (Wang et al., 2010)되며 C/N율은 토양 탄소와 밀접하게 관련 있으며 바이오메스 품질 (Mirsky et al., 2008)과 바이오메스 분해율을 결정하는 중요한 요인(Kemp et al., 2003) 이므로 본 연구에서 호밀과 트리티케일+헤어리베치는 녹비작물로 바이오메스 생산량도 높고 토양 탄소 함량 증진에도 효과가 높아 이산화탄소 저감에 효과적일 것이다.
