초록

수년간 고추를 연작한 비닐하우스에서는 연작 또는 염류집적에 따른 수량감소가 현저하게 나타난다. 고추의 수량감소를 줄이면서 설치한 비닐하우스의 사용연한을 연장시킬 수 있는 수단으로 기존 토양에 왕겨를 혼합한 소토양관비재배의 가능성을 검토하였다. 소토양관비재배 시험구에서는 관행재배 시험구에 비하여 토양 EC가 $4dS\;m^{-1}$ 이하로 낮아졌으며 두 재배방법 사이에 지상부 생육의 차이는 크지 않았으나 뿌리의 발달은 소토양관비재배 시험구에서 현저히 좋았다. 특히 소토양관비재배 시험구에서는 잔뿌리의 발달이 많았으며 관행재배 시험구에서는 뿌리 양이 적을 뿐만 아니라 굵은 뿌리가 많이 발생되었다. 풋고추 수량은 소토양관비재배 시험구에서 43% 정도 증가되었는데, 이는 소토양관비재배 시험구에서의 양호한 뿌리 발달이 양분흡수에 기여하였고 결과적으로 수량 증대로 이어진 것으로 판단된다. 본 논문은 초기 단계의 연구결과이며, 소토양관비재배방법이 연작 토양 시설물의 이용효율을 극대화할 수 있는 방법의 하나로 그 가능성을 제시하였을 뿐이다. 소토양관비재배방법의 실용화를 위해서는 보다 구체적인 연구가 더 진행되어야 할 것이다.

Salinity problems are caused from the accumulation of soluble salts in the root zone. These excess salts reduce plant growth and vigor by altering water uptake and causing ion-specific toxicities or imbalances. In this investigation, green pepper cultivation technique using mixture bed of soil and rice hull and surface drop fertigation system was examined to prolong the productivity of salt-affected plastic film house soils. Green pepper growth was better in the mixture bed of soil and rice hull comparing to the conventional soil cultivation. Especially root growth was much better and the root had more thin root system in the mixture bed of soil and rice hull. The better growth of root may be due to the better physical conditions and lower EC in the mixture bed of soil and rice hull where nutrient supply was well-managed with fertigation system. In the cultivation with mixture bed of soil and rice hull, fruit yield of green pepper was significantly higher; increased by 43% in comparison to the conventional soil cultivation. Pepper cultivation technique using mixture bed of soil and rice hull and surface drop fertigation system is expected to be a useful method for maintaining and prolonging the productivity of salt-affected plastic film house soils.
