采用谷氨酸钠、CaCl2和VB 6三种叶面肥喷施茶树，调查三种叶面肥喷施对茶鲜叶和产品红茶中GABA含量的影响。结果表明，三种叶面肥均可显著提高茶鲜叶中GABA含量，在浓度分别为5、5、0.3 g/L时，茶鲜叶中GABA含量最高分别为0.77、0.51、0.48 mg/g，制成的产品红茶中GABA含量显著降低至0.45、0.1、0.08 mg/g。说明三种叶面肥喷施均可促进茶叶中GABA的富集，而红茶加工工序可造成GABA大量损失。
採用穀氨痠鈉、CaCl2和VB 6三種葉麵肥噴施茶樹，調查三種葉麵肥噴施對茶鮮葉和產品紅茶中GABA含量的影響。結果錶明，三種葉麵肥均可顯著提高茶鮮葉中GABA含量，在濃度分彆為5、5、0.3 g/L時，茶鮮葉中GABA含量最高分彆為0.77、0.51、0.48 mg/g，製成的產品紅茶中GABA含量顯著降低至0.45、0.1、0.08 mg/g。說明三種葉麵肥噴施均可促進茶葉中GABA的富集，而紅茶加工工序可造成GABA大量損失。

Influence of three foliar fertilizers (Monosodium Glutamate, CaCl2 and VB6) by spraying tea plants on GABA content in fresh tea leaves and black tea were investigated. The result showed that: the three foliar fertilizers could increase significantly the GABA content in fresh tea leaves. The GABA content in fresh leaves maximum reach 0.77, 0.51, 0.48 mg/g at three foliar fertilizers concentration of 5, 5,0.3 g/L, respectively, Which made from black tea, the GABA content significantly reduced to 0.45, 0.1, 0.08 mg/g. It was found that the foliar fertilizers (Monosodium Glutamate, CaCl2 and VB6) could promote the GABA enrichment of tea, while the processing operations of black tea may result in a substantial loss of GABA.
