Abstract
본 연구는 현재 방조제는 완공되었으나 지반이 약한 간척지에서 비닐하우스를 활용한 겨울감자 재배 가능성을 검토하고자 피복비닐 및 물관리 방법을 달리하여 시험한 결과를 요약하면 다음과 같다. 1. 시험토양은 사양토(문포통) 이었으며, 정식 당시 토양염농도는 0.42% 이었다. 2. 피복비닐종류별 출현속도는 흑색>배색>투명>녹색 순으로 흑색비닐에서 초기 출현속도가 빨랐고, 1일중 온도변화는 투명>배색>녹색>흑색 순으로 높았다. 3. 물관리방법별 토양중 염농도는 1주간격 점적관수가 2주간격 점적관수보다 낮았다. 4. 수확당시 지상부 생육은 1주간격 점적관수처리가 2주 간격 점적관수처리보다 초장이 컸고 경수와 엽수가 많았으며 지상부 건물중도 무거웠다. 5. 물관리방법간 감자수량은 1주간격 점적관수가 2주간격 점적관수보다 많았고, 1주간격 점적관수에서 피복 비닐종류간에는 투명${\geq}$흑색${\geq}$배색>녹색 순 이었다. 6. 항산화분석결과, 배색피복비닐 처리에서 총페놀과 DPPH 함량이 우수하게 나타났다. This study was conducted to measure the effect of PE film mulching and irrigation methods on the growth, yield and antioxidant activity of potatoes tubers, in order to examine the possibility of cultivating potatoes in winter season in vinyl greenhouse on the reclaimed tidal land with weak ground inside the sea wall currently completed. The test was conducted on the sandy loam soil (Munpo series), and its salt concentration was 0.42% at the time of planting. The emergence speed per kind of PE film mulching was in the order of black > coloration > transparent > green color, with the black color showing the fastest speed. The temperature change during a day per kind of PE film mulching was in the order of transparent > coloration > green > black color. As for the salt concentration in the soil for each different way of water management, the salt concentration in the treatment of drip irrigation with 1 week interval was lower than that drip irrigation with 2 weeks interval. As for the growth of above-aerial part, plant length was higher, number of tiller and leaves were more and dry weight of above-aerial part was larger in the treatment of drip irrigaton with 1 week interval than drip irrigation with 2 weeks interval. As for the yield of potatoes depending on each way of water management, the yield in the treatment of drip irrigation with 1 week interval was more than drip irrigation with 2 weeks interval. The yield for each different kind of PE film mulching in the weekly drip-irrigation management section was in the order of transparent ${\geq}$ black ${\geq}$ coloration ${\geq}$ green color. In both of total phenol content and DPPH free radical activity experiments, the content and activity were higher with pear color vinyl treatment.
