Abstract

This study was conducted to investigate the effects of soil amendment with different characteristics on plant growth, fruit yield and quality of oriental melon for continuous cropping under protected cultivation. Humus layers in arable soil was disturbed because soil amendment from hillside to oriental melon field was continued to resolve problems for continuous cropping. Water potential and hardness of soil was decreased in sandy loam with lower clay contents compared with loam and silty clay. Leaf length and area, fresh and dry weight of plant at earlier growing stage were higher, but chlorophyll contents of leaves were dropped in sandy loam compared with silty clay soil. Fruit size and weight was higher in sandy loam, but soluble solid and color of fruit were increased in silty clay. Marketable and unmarketable yield and quantity of fermented fruit were the highest in sandy loam. Hardness and weight of fruit were decreased by longer storage period and soluble solids of fruit was peaked at 5 day after storage, but decreased by prolonged continued storage. Because of these results, soil characteristics of amendment to oriental melon field should be considered as an important factor for quality and yield of oriental melon.

시설참외 재배지 연작장해 경감을 위한 객토시 토성이 생육과 과실의 품질 및 수량에 미치는 영향을 조사하였다. 객토시 기존 작토층에 함유된 유ㆍ무기물질들은 교반으로 감소되었고, 토양수분 장력은 점토함량이 낮은 사양토가 양토와 미사질식토 보다 감소폭이 크게 나타났으나 토양경도의 증가폭은 낮았다. 초기 생육은 사양토에서 초장과 엽면적 그리고 지상ㆍ지하부 생체중과 건물중이 모두 높은 경향을 보였으나 엽록소함량은 낮았다. 과실은 사양토에서 크고 무거웠으며 단도와 색은 미사질식토에서 높게 나타났다. 상품과와 비상품과 수량은 사양토에서 가장 많았으며 또한 발효과 발생률도 높게 나타났다. 저장기간이 경과할수록 모든 토성에서 경도와 과중은 서서히 감소되었으나 당도는 저장 후 5일까지 증가한 후 감소되었다. 따라서 시설참외 재배지 객토시 과실의 품질과 수량에 영향을 미치는 토성이 고려되어야 하겠다.
