Abstract
본 연구에서는 새만금 지역에 조성된 신간척지 포장에서 담수와 하작물 재배처리가 제염 및 후작으로 재배한 청보리의 생육 및 수량에 미치는 영향을 조사 분석하여, 신간척지 포장의 조기제염 기술을 개발하고자 하였다. 1. 담수기간별 하작물 재배후 청보리 입모를 보면 무담수에서 $m^2$당 216개로 입모율 25%, 1개월 담수 43%, 2개월과 3개월 담수 58%, 벼 재배구는 60% 이었다. 2. 토양염농도는 청보리 파종 시에 무담수 처리에서 0.50%로 높았고, 그 외 담수처리에서는 0.2% 이내로 낮았으며, 생육 중기까지는 높아지다가 생육후기에는 파종시의 수준과 비슷하였다. 3. 초장과 간장은 담수기간이 길수록 많았으며, 경수도 많아지는 경향이었다. 4. 수량은 무담수에서는 극히 적었으며, 담수기간이 길수록 수량은 급격히 증가하여, 무담수 대비 3개월 담수에서 504%, 벼 재배에서는 536% 증수하였다. 5. 사료가치는 담수 1개월은 단백질함량과 섬유소함량이 낮게 나타났고, 담수 3개월은 벼 재배구와 사료가치 면에서 비슷한 결과를 보였다. 이상의 결과를 종합하여 볼 때, 새로 조성된 간척지(사양토)에서 제염을 목적으로 담수할 경우 3개월 이상 담수하거나 벼를 재배하여 제염을 하고 밭작물(청보리)을 재배하여야 어느 정도 수량을 얻을 수 있을 것으로 판단된다. This study was conducted to investigate upland crop at reclaimed sand land 'Saemangeum' for early desalination purpose and to investigate the growth and yield of whole crop barley, which was acceded after summer crop of corn and rice. Seedling establishment of whole crop barley were 216 seedlings/$m^2$(25%) for non-flooding, 43% for 1 month and 58% for 2, 3 month flooding. And it was 60% in rice cultivation. Soil salt concentration was 0.5% in non-flooding treatment, however flooding treatments decreased to 0.2% or less. In general soil salt concentration increased until the middle stage of growing, then became to similar level as the seeding time. Plant height, stem length and number of tiller were increased with flooding treatment. Whole crop barley yield was significantly reduced in non-flooding treatment but rapidly increased by flooding treatment. Yielding at 3 months increased by 504% compared to non-flooding, and rice cultivation was also increased by 536%. Protein and fiber content was low in 1 month flooding treatment, 3 months flooding and rice cultivation showed the similar results in terms of feed value. For desalination purpose in reclaimed land, 3 months flooding treatments of rice cultivation could result in higher yielding for upland crop, such as whole crop barley.
