于拓地에 生育하는 數種의 鹽生植物中에서 퉁퉁마디(Salicornia)에 依한 鹽素이온의 吸收가 最大値를 보여주었고, 그다음은 갯솔나물(Suaeda), 버들잎명아주(Chenopodium) , 세모골(Scirpus)의 순서였다. 퉁퉁마디가 調密하게 자라는 地域의 表層 最大容水豊은 52%로서 最大였으나 下層의 경우는 거의 비슷한 含量을 나타내었다. 土壤의 pH 는 表層에서 一定한 傾向을 보여주지 않았고 下層은 比較的 一定하였다. 土壤의 연령별 고도는 역시 퉁퉁마디가 調密하게 生育하는 土壤에서 最下를 나타내었고 下層의 경우는 10年(논)이 경과한 土壤의 鹽度와 비슷한 값을 나타내었다. 試驗地 土壤의 化學的 成分中에서 NO_3-N^1와 phoshorous 는 上下層모두 6月에 增加를 보이고 有機物, magnesium, potassium 等은 季節的인 差異를 보여주지 않았는데 이는 沿岸干拓地의 독특한 현상인 Coastal Circulation 때문이라고 推測된다.
Korea has a lots of margin for security of farm land from her coastal region. The area of saline soil may be reached about 10% of present farm land if the reclamatien works are finished. This paper was conducted as a part of studying the possibillities of desalination of saline soil through the experiment of some halophytes. The halophytes in this works were Salicornia herbacea L., Suaeda glauca Bunge, chenopodium acuminatum Willd, and Scirpus triquerter L. Of the above halophytes. Salicornia was proved the most effective plant for desalinatlon of saline soil referring to the following results; 1) The seasonal uptake of chlolride by Salicornia was the highest of all. However, the general tendencies of all plants showed a decrease on August. 2) Salinity of soil showed the lowest value on the site where Salicornia was grown densely. Comparing the other sites grouped by age of saline soil with the above site, the salinity of rice-paddy (10 years after reclamation) is similar to those of the site where Salicornia were as well as the 50 ㎝ below the surface soil. 3) The maximum water holding capacity of surface soil appeared in the site of Salicornia, but in 50 ㎝ below the surface, the maximum water holding capacity are almost on equal terms having no connection with the age of saline soil. Soil pH, other chemical compositions such as organic matter magnesium, potassium, phosphorous, and nitrate were determined to elucidate the relationship between the changes of soli properties and chemical uptakes by certain halophytes. It is assumed that the above chemical compositions are frequently affected by the factors such as coastal circulation of salts, exchangeable base, microbial growth, climatic conditions. and irrigation of water.
