灌溉条件下苏打盐渍化土壤环境变化及其生物效应
Environment Influence and Biological Effects in Sodic Salinization Soil under Irrigation Condition
摘要
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 paddy.Prevention and cure measures on the physiological diseases of paddy are also proposed.关键词
