Study on the relationship between scirpus planiculmis grow and soil salinity

Abstract. Through study on the relationship between scirpus planiculmis growth and soil in momoge wetland, it is discovered that the relationship between the average plant height and soil salt content is:, relationship between aboveground biomass and soil salt content:; The critical growth value of the Scirpus planiculmis without or with small outside interference is relatively small; their height, ground biomass, salinity content are 24.4cm, 4.745g and 1.100%, respectively; when there is outside interference in a certain time, the critical value of growth of Scirpus planiculmis is high,their height, ground biomass, salinity content are 23.2cm, 4.179g and 0.977%, respectively.
