Abstract: In this paper,the chemical characteristics of sodic salinization soil and environmental influences of rootzone soil under different irrigation conditions are studied in western Jilin Province,and the obstacle effects of sodic salinization environment on vegetation growth are analysed Furthermore,excessive Na+ accumulation in paddy can antagonize the absorption of nourishment elements(Ca2,Mg2) and microelements(Zn,Cu),and the antagonism is obvious At last,it is concluded that physiological diseases of paddy have consanguineous relationships with the antagonism among different elements in paddyPrevention and cure measures on the physiological diseases of paddy are also proposed.

Key words: Lüsi fishing ground, fish, ecological group, species composition, dominant species.
