노지 고추 연작 토양의 미생물 인지질 지방산 함량

국문 초록 (Abstract)

본 연구는 고추 연작의 작부체계가 토양 미생물의 변화에 미치는 효과를 분석하고자 10년 동안 무농약 및 화학적 무비료의 시용방법으로 수행되었다. 지표 PLFAs 분석을 통해 토양미생물상과 활성도를 평가하였다. 고추와 마늘의 단작, 마늘과 고추의 간작의 작부체계에 따른 토양의 화학학성은 큰 차이를 보이지 않았으나 토양 미생물의 PLFAs의 다양성은 PC2에서 다른 작부체계와 상이한 미생물상으로 구분되었으며, 토양 미생물의 PLFAs의 총량은 마늘 단작구와 비교하여 고추 단작구에서 유의적인 감소를 보였으며, 미생물군집의 구조는 내생균근균의 비율에서 유의성있는 감소를 보였다. 이는 마늘과 고추의 근계에 따라 내생균근균의 미생물체량의 감소하였으며, 이것이 토양미생물상과 활성도를 다른 작부체계와 구분한 것으로 판단된다.

다국어 초록 (Multilingual Abstract)

This study was carried out to investigate the effect of continuous cropping of pepper on soil microbial phospholipid fatty acids (PLFAs) under upland applied without any pesticides and chemical herbicides from 2000 to 2009. Microbial PLFAs were analysed from soils sampled in 2009. Soil microbial diversities showed PLFAs of monoplanting of pepper were distinct from those of monoplanting of garlic and interplanting of garlic and pepper by principle component 2 (PC2). Furthermore, soil microbial activity of monoplanting of pepper significantly decreased PLFAs representing as VAM-fungi, whereas it significantly increased in actinomycetes and saturated/monounsaturated PLFAs" ratio. The results drove continuous cropping of pepper would vary the microbial community and their specific activity. Soil microbial activities in continuous cropping system would depend on crop root systems.
