Ecological studies of the certain Halophytes on the high saline soil

고염도 토양에 있어서 몇가지 염식생식물의 생태에 대하여

Ecological study on the reclaimed high saline soil was carried out throughout a year(1969) to elucidate the changes of the structure of halophytes communiteis and the possibilities of desalination from high saline soil by absorption of chloride ion. Results from this studies are summarized as followings; 1) The growth rates of halophytes showed a variation; maximum growth rate of Salicornia appeared on August, Chenopodium on July, Suaeda on July, Aster on August and Scirpus on June. 2) Changes of frequency of each halophyte were varied in accordance with species. Chenopodium and Salicornia have the highest frequency of all on May. However, frequency as well as density of halophytes decreased after on May due to competition for absorbing moisture in plant communities. 3) The terrestrial plants which were succeed into the reclaimed tidal land had herborized 25 species on the both side of irrigation route. 4) Each of the maximum chloride uptake by halophytes appeared on May(Salicornia and Aster), on June(Chenopodium and Scirpus), and on August(Suaeda), respectirecely 5) Among the halophytes, Salicornia was confirmed to absorb the highest amount of chloride. A possible amount of chloride uptake by all halophytes per 100 square cm reached about 24,629. ppm.
