본 연구는 양파 재배 중 양파와 쇠비름 수액 처리가 무처리구와 비교하여 양파의 수량 및 품질 특성 에 미치는 영향을 분석하고자 하였다. 초장, 엽수 및 엽초경은 양파 생육 전반에서 양파와 쇠비름 추출 액 혼용 처리구가 양파 추출액 처리구와 무처리구에 비해 생육이 양호하였다. 양파 수량은 양파와 쇠비 름 추출액 혼용 처리구가 양파 추출액 처리구 보다 10a당 4.4% 증가 되었으나 유의성이 없었고, 무처 리구 보다는 14.3% 증가되어 유의성을 나타내었다(p<0.05). 양파의 경도는 양파와 쇠비름 추출액 혼용 처리구가 양파 추출액 처리구와 무처리구에 비해 각각 15%와 20% 높아 유의성을 나타내었으나 (p<0.05), 당도는 양파 추출액 처리구에서 양파와 쇠비름 추출액 혼용 처리구와 무처리구 보다 3% 증 가되어 유의성이 나타나지 않았다. 양파의 무기성분 함량은 양파와 쇠비름 추출액 혼용 처리구 양파에 서 K2O와 CaO 제외한 다량원소들이 높게 함유되었다. 양파 생육 시험 후 토양의 무기성분 함량은 양 파와 쇠비름 추출액 혼용 처리구에서 유효인산, 칼륨, 철, 망간, 아연, 구리에서 높게 나타났다.
This study was carried out to analyse productivity and quality of onions applied with defective onion and purslane extracts during cultivation. The general growth of onion, such as plant height, number of leaves and sheath diameter, at different growing stages was better at treatment of onion plus purslane extract compared to treatment of onion extract and non-treatment. Yield of onion was increased by 4.4% at treatment of onion plus purslane extract compared to treatment of onion extract, but there was no significant difference. It was also increased significantly by 14.3% at treatment of onion plus purslane extract compared to non-treatment (p<0.05). Hardness of onion grown on treatment of onion plus purslane extract was increased significantly by 15% and 20% compared to onion grown on treatment of onion extract and non-treatment, respectively (p<0.05). Sugar content of onion grown on treatment of onion extract was increased by 3% compared to onions grown on treatment of onion plus purslane extract and non-treatment, but there was no significant difference. The onion grown on treatment of onion plus purslane extract contained high mineral compositions except K2O and CaO. After onion harvest, the mineral compositions on soil treated with onion plus purslane extract was high with P2O5, K, Fe, Mn, Zn and Cu compared to those on soil treated with onion extract and non-treatment.
