Abstract

This study was conducted to evaluate the effect of rice cover crop cropping systems on rice root growth in a rice field as affected by conventional tillage without rice straw or green manure crop treatment (CTFS, check plot), no-tillage without cover crops (NTNT), no-tillage amended with rape (NTRA), no-tillage amended with rye (NTRY), no-tillage amended with hairyvetch (NTHV), and no-tillage amended with Chinese milk vetch (NTCM). In 0-5 cm soil depth, dry weight of root in NTRS ($128g\;m^{-2}$) was significantly higher than in the other plots (p<0.05) at harvesting stage. In addition, content of active organic matter at 0-5 cm soil depth was $1,684g\;m^{-2}$ in NTCM, $1,309g\;m^{-2}$ in NTRA, $1,295g\;m^{-2}$ in NTRS, $1,072g\;m^{-2}$ in NTRY, $917g\;m^{-2}$ in NTHV, $434g\;m^{-2}$ CTFS, and $426g\;m^{-2}$ in NTNT treatment. In no-tillage rice cover crop cropping system, our findings suggest that NTRS and NTCM should be enhanced root growth and active organic matter in paddy field.

무경운 논에서 피복작물로 자운영, 볏짚, 헤어리베치, 유채, 호밀 등을 처리하고 토양 깊이별 벼 뿌리의 생육상황과 활성 유기물 함량을 조사하였다. 벼 생육초기 주당 발근량은 무경운 유채 처리구가 256 cm로 가장 양호하였으며 무경운 자운영 처리구는 214 cm, 관행은 176 cm, 무경운 헤어리베치 처리구는 139 cm, 무경운 호밀 처리구는 106 cm, 무경운 녹비무처리는 104 cm, 무경운 볏짚 처리구는 99 cm 순으로 나타났다. 토양 깊이 0-5 cm에서 무경운 볏짚 처리구에서 $128g\;m^{-2}$로 다른 처리구에 비해 유의적으로 높았다 (p<0.05). 무경운 자운영 처리구도 $83.5g\;m^{-2}$로 무경운 볏짚 처리구를 제외한 다른 처리구에 비해 유의적인 차이를 보였으며 무경운 헤어리베치 처리는 $53.0g\;m^{-2}$으로 가장 낮았다. 토양 깊이별 활성 유기물 함량은 0-5 cm 에서 무경운 자운영 처리구가 $1,684g\;m^{-2}$으로 가장 많았으며 무경운 유채 처리구 $1,309g\;m^{-2}$, 무경운 볏짚 처리구 $1,295g\;m^{-2}$, 무경운 호밀 처리구 $1,072g\;m^{-2}$, 무경운 헤어 리베치 처리구 $917g\;m^{-2}$ 순이었고 관행은 $434g\;m^{-2}$, 무경운 녹비 무처리구는 $426g\;m^{-2}$으로 매우 낮은 함량을 보였다. 본 연구결과 무경운 피복작물 작부체계에서 볏짚 처리구와 자운영 처리구는 벼 뿌리 생육과 활성 유기물 함량을 증대시키는 것으로 판단되었다.
