摘要：

土壤中的铁和锰均为植物生长发育的有益元素。采用二次饱和D－最优试验设计进行茶树盆栽土培试验，以铁、锰肥为自变量，茶叶氨基酸、咖啡碱、茶多酚和可溶性糖含量为目标函数，设二因素五水平，探讨了铁锰配施对茶叶品质的影响。结果表明：当锰肥施用浓度为0.12 g/kg和铁肥施用浓度为0.03 g/kg时，茶叶中茶多酚和咖啡碱含量交互效应最高，平均含量分别为24.78%和2.96%；当锰肥施用浓度为0.12 g/kg和铁肥施用浓度为0.24 g/kg时，茶叶中氨基酸和可溶性糖含量交互效应最高，达到理论最高值，平均含量分别为2.19%和2.65%。

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%.
