‘뚝섬적축면상추’, ‘잔치열무’, ‘다조은엇갈이배추’에 대한 본포 재배기간 동안 터널 막덮기재배에 있어서 막덮기 자재 종류간에 터널 내 기상, 생육 및 해충 발생에 미치는 영향을 조사하였다. 피복자재별 투광률 은 무피복(100%)에 비해 네트류가 90% 정도를 보였으며, 부직포는 83~89%로 다소 낮았다. 평균기온과 지온은 무피복에 비해 네트와 한랭사 피복에서 0.3~ 1oC, 부직포는 0.5~3oC 상승하였다. 그러나 상대습도는 처리 간에 차이가 없었다. 열무, 엇갈이배추, 상추 모 두 무피복에 비해 부직포 막덮기에서 생육이 촉진되었 는데, 상추는 81%, 열무는 58%, 엇갈이배추는 93% 정도의 증수 효과가 있었다. 특히 부직포 피복에 의해 해충의 피해가 크게 경감되었다.


This study was carried out to evaluate the effects of row cover materials supported by flexible FRP frames with three kinds of non-woven fabric, and five kinds of net in leaf vegetable cultivation. Leaf radish (Raphanus sativus L.), Chinese cabbage (Brassica rapa L. ssp. pekinensis) were sown on May 21, 2003, and leaf lettuce (Lactuca sativa L.) was planted at the same date in Agricultural Research Center for Climate Change, Jeju, Korea. Net coverings showed higher light transmittance than in non-woven fabric coverings. The average air and soil temperatures increased by 0.3~1.0oC in net coverings and 0.5~3.0oC in non-woven fabric coverings, respectively. There was no difference in relative humidity among the covering materials. All the vegetables showed higher growths and yields in non-woven coverings than in non-covering. The yields increased 81% in leaf lettuce, 58% in leaf radish, and 93% in Chinese cabbage, respectively. In addition, the insect damages were considerably reduced in the row covering plots than in the control, especially in non-woven fabric coverings.
