본 연구는 새만금 간척지에서 비닐하우스 작물 재배 가능성 검토를 위해 녹색꽃양배추를 대상으로 일일 관수량을 달리하여 관수량에 따른 토양 염농도 및 생육특성 등을 조사하여 관수량에 의한 재염화 억제효과를 알아보고자 수행하였다. 수확기의 표토의 평균 토양 EC 는 1.5 및 3.0mm·day<SUP>-1</SUP> 처리구에서 각각 10.9 및 11.5dS·m<SUP>-1</SUP>였으며 6.0mm·day<SUP>-1</SUP> 처리구에서 5.1dS·m<SUP>-1</SUP>로 1.5 및 3.0mm·day<SUP>-1</SUP> 처리구보다 52~56% 낮게 나타나 점적관수량에 따른 제염효과를 확인할 수 있었다. 화뢰의 무게는 6.0mm·day<SUP>-1</SUP> 처리구에서 주당 371.3g으로 1.5 및 3.0mm·day<SUP>-1</SUP> 처리구의 60.9g 및 129.1g보다 높은 값을 나타냈다. 50%의 수량감소를 보이는 토양 EC는 7.6dS·m<SUP>-1</SUP>였으며 점적관수에 의한 토양 제염효과는 6.0mm·day<SUP>-1</SUP> 처리에서 30~40cm 깊이까지 나타났다. 따라서 새만금간척지에서 녹색꽃양배추 재배시 점적관수에 의한 토양 재염화 억제를 위해서는 6.0mm·day<SUP>-1</SUP> 수준의 관수량으로 총 422mm의 물량이 필요할 것으로 예측된다. 그러나 염류의 이동은 토양 이화학적 특성 및 계절적 요인 등 여러 가지 환경요인에 영향을 받으므로 간척지 비닐하우스에서 점적관수에 따른 염류의 이동특성에 관한 추가적인 연구가 필요할 것으로 판단된다. The objective of this study was to investigate the effect of drip irrigation level on soil salinity and growth of broccoli (Brassica oleracea L. var. italica) at the ‘Saemangeum Reclaimed Tidal Land’ from April to June, 2015. Drip irrigation was conducted at 1.5, 3.0 and 6.0mm·day<SUP>-1</SUP> level for reduction of resalinization in the plastic vinyl house using 10cm spacing drip irrigation tape. At harvesting stage, the average EC of surface soil was 10.9dS·m<SUP>-1</SUP> for 1.5mm·day<SUP>-1</SUP>, 11.5dS·m<SUP>-1</SUP> for 3.0mm·day<SUP>-1</SUP> and 5.1dS·m<SUP>-1</SUP> for 6.0mm·day<SUP>-1</SUP> and was significantly reduced by 52~56% in 6.0mm·day<SUP>-1</SUP> treated plot compared to those in 1.5 and 3.0mm·day<SUP>-1</SUP> plots. The fresh bud weights of 1.5, 3.0 and 6.0mm·day<SUP>-1</SUP> treatment plots were 60.9, 129.1 and 371.3g·plant<SUP>-1</SUP>, respectively. The estimated soil EC for 50% yield reduction was 7.6dS·m<SUP>-1</SUP> and the desalinization depth by drip irrigation was 30~40cm in soil profile. The total amount of drip irrigation water was estimated to be 422mm and the daily drip irrigation level was 6.0mm·day<SUP>-1</SUP> for the prevention of resalinization during the broccoli growing period at the ‘Saemangeum Reclaimed Tidal Land’. Our results suggested that drip irrigation shows effectiveness on the lowering the soil salinity according to the drip irrigation quantity but it needs more research on this study because dynamics of salts in soil can vary with many factors such as soil physico-chemical properties and seasonal climate.

<P>Summary</P><P>This study was conducted to investigate the effect of drying in antioxidant activity and to compare the changes of ascorbic acid and colour by drying and storage in Korean red pepper. The antioxidant activity of red pepper dried by modified method (MM, dried at 70 °C/6 h in cut pods) was about threefold higher than those dried by conventional method (CM, dried at 80 °C/5 h followed by 60 °C/18 h in whole pods) in the ([2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid)] (ABTS) and (2,2-diphenyl-1-picrylhydrazyl) (DPPH) radical-scavenging assays, respectively. The ascorbic acid contents in MM and CM drying were 12.41 ± 2.15 mg g<SUP>−1</SUP> and 3.05 ± 0.39 mg g<SUP>−1</SUP>, and were not changed for 3 months at 0 °C in red pepper dried by MM. The ASTA colour values of red pepper dried by MM and CM were 114.0 and 107.4, respectively. For 6- month storage, 72–85% of the colour was retained regardless of drying and storage conditions.</P>

Hui Su Bae,Seung Hyeon Ahn,Jaebok Hwang,Hyeonsoo Jang,Jong Tak Youn,Uk Han Kim,Tae Seon Park,Beomsoo Bae 한국토양비료학회 2019 한국토양비료학회지 Vol.52 No.4
Influences of various soil chemical properties on the algae growth (Chl-a concentration) at the paddy field were statistically analyzed using soil and water samples collected from 2016 to 2018 in June. As a result of correlation analysis between soil chemical properties and Chl-a concentration, significantly positive relationships were observed in pH, EC and SiO₂. To identify the key soil chemistry variables and predict Chl-a concentration, factor analysis was done and three principal components (PCs) with eigenvalues > 1 were found, which accounting for 60.9% of the original variance. The PC1 included Mg<SUP>2+</SUP>, Ca<SUP>2+</SUP> and Avali.-P. The PC2 included pH, Na<SUP>+</SUP>, K<SUP>+</SUP>, and Avail.-SiO₂. PC3 included OM and T-N. According to the result of linear regression analysis based on the factors by factor analysis, the total explanation amount was 18.0% and only PC3 had an significant influence on the decrease of Chl-a concentration. These result will be used for soil management to prevent algae blooms at rice paddy field.
