According to the technical standards of agriculture environmental quality monitoring, the environmental quality of jasmine scented tea plantation in planting demonstration region in Hengxian, Guangxi was analyzed for pollutants and its control strategy to provide scientific basis on safety production of pollution-free jasmine tea has beed discussed. The results showed that the comprehensive pollution index of atmosphere, irrigation water and soil in 2007 was 0.108, 0.123 and 0.931, respectively, and the environmental conditions could meet the demand for producing pollution-free jasmine tea. The single pollution index of all the tested items was less than 1.0 except that of Hg in soil. This indicated that the Hg content in soil was the key control factor of soil quality. The other pollutants in environment were lower than the limitation value, while the air suspensions and the concentrations of Cd and As in soil did not go beyond the limit but found in considerable amount, that may become the potential pollutant for jasmine tea.
