Abstract:

Manganese and EDTA-Fe in the soil both are the beneficial elements for plant growth. Effects under combined treatment of Manganese and EDTA-Fe on quality of Mengshan tea were studied using D- Saturating Optimum Design. The results showed that, when Manganese concentration of treating was 0.12g/kg and EDTA-Fe concentration was 0.03g/kg, the interactive effects of the tea polyphones and Caffeine were highest, and the average contents were 24.78% and 2.96%. when Manganese concentration of treating was0.12g/kg and EDTA-Fe concentration was 0.24g/kg , the interactive effects of the amino acid and the soluble sugar were highest and reached the theoretical maximum, and the average contents were 2.19% and 2.65%.
