Field plot experiments were conducted to study the effects of different doses of Symbex products (i.e., clear water, 50 times, 100 times, 150 times, 200 times and 250 times diluent) on tea yield, quality and soil fertility. The results showed that, compared with CK (clear water), applying different doses of Symbex diluent could increase the density of tea bud head by 2.7% ∼ 25.3%, 100 bud weight by 3.6% ∼ 21.1%, internode length by 5.3% ∼ 21.1%, increase annual fresh tea yield by 7.6% ∼ 37.9%, increase tea polyphenols by 9.4% ∼ 41.4%, amino acids by 7.1% ∼ 39.3%, soluble sugar by 9.4% ∼ 41.4%, and water extract by 7.5%∼43.9%. Results also showed that the soil organic matter, available nitrogen, available phosphorus and available potassium in the topsoil of tea garden increased by 2.4% ∼ 29.8%, 13.7% ∼ 98.1%, 26.2% ∼ 98.0% and 24.4% ∼ 102.2% respectively. Among them, T200 (Symbex 200 times diluent) and T250 (Symbex 250 times diluent) treatments had better effects on improving the morphological indexes and biochemical composition indexes of tea garden, increasing the yield of fresh tea leaves, and improving the basic available nutrient content in the topsoil of tea garden.
