양파 파치 추출물이 유기농 양파성에 미치는 영향

국문 초록 (Abstract)

양파는 2모작 작물로써 소득이 큰 작물이면서 건강에 좋은 기능성분이 많이 함유하고 있어 생산자와 소비자에게 인기가 높은 식품이다. 최근 건강과 환경을 중시하는 생활패턴 때문에 소비자는 유기농 양파를 더 선호할 것으로 예상되나 자연생태계를 고려하면서 안정적이고 건강한 먹거리를 생산하기는 매우 어렵다. 유기농법의 한계를 극복하고자 양파 잔재물에서 증류법으로 양파 추출액을 채취하여 유기농양파 재배기간 중에 500배로 희석하여 7번 되돌려 주고 생산성과 관련된 생육, 수량, 양분 및 토양미생물을 비교한 결과는 다음과 같았다.
1. 양파의 생육은 대체로 대조구<순환구<관행구 순으로 좋았으며, 초기에는 순환구가 관행구보다 현저히 불량하였으나 후기에 갈수록 처리간 차이가 줄어져 비슷하였다.
2. 양파의 수량은 순환구가 대조구보다 9.3% 증가되었고 관행구보다 11.0% 감소되었으며, 300 g 이상 구중 분포비율이 높을수록 수량도 많아지는 경향이었다.
3. 양파의 무기성분 함량은 순환구가 대조구와 관행구보다 많았으며, 특히 인산, 철, 아연 함량 등은 관행구에 비하여 47%, 78%, 172% 현저히 증가되었다.
4. 양파의 유기성분 함량은 순환구가 대조구와 관행구보다 많았으며, 퀘세틴 함량은 순환구가 대조구와 관행구에 비하여 각각 33.9%, 44.0% 증가되었다.
5. 토양의 내생 균근균은 순환구가 대조구와 관행구에 비하여 각각 40%, 31.7% 더 많았고 미생물 스트레스 지표는 순환구가 대조구와 관행구에 비하여 15%, 20% 감소되었다.

다국어 초록 (Multilingual Abstract)

This study evaluated the close crop recycling method by using the extract from defective onions. The mixture of the diluted extract (1/500) and nutrients was applied seven times on the onion leaves without spilling it onto the field. The yield and quality of the onions produced by this method (recycle) were compared to those grown organically (control) and conventionally (normal). The yield from the recycling field was increased significantly by 9% compared to that of the control field, while it was decreased by 11% compared to the normal field (p < 0.05). This lower yield was explained by the differences of the mulching vinyl and the fertilizers between the treatments which effect the onion growth during the winter. The content of quercetin in the onions from the recycling filed was increased significantly by 34% and 44% compared to those of the control and normal field, respectively (p < 0.05). It seemed that minerals and biologically active substances in the defective onion extract were effective in increasing the onion growth. In terms of soil microbial biomass, arbuscular mycorrhizal fungi was increased significantly in the recycle field by 40.1% and 30.6% compared to those of the control and normal fields, respectively (p < 0.05). On the other hand, microbial stress (cy19:0/18:1w7c) was decreased in the recycle field by 21.0% and 14.1% compared to those of the control and normal fields, respectively.
