AI Technical Summary
While improving the stress resistance and soil structure of Pu'er tea trees, it is difficult to effectively improve the phenol ammonia ratio of Pu'er tea and the yield of one tea and two leaves, which cannot meet the market's demand for high-quality Pu'er tea.
By adding green algae fermentation and plant enzymatic hydrolysate to silicon calcium fertilizer, the two play a synergistic role, promoting the synthesis of tea tree amino acids and inhibiting the synthesis of tea polyphenols, thereby improving the phenol-ammonia ratio of tea leaves. At the same time, small molecules of organic matter in plant enzymes are absorbed by tea trees, promoting their growth and development and increasing the yield of one tea and two leaves.
It significantly improves the phenol-ammonia ratio of Pu'er tea, improves the taste of the tea, makes it softer and smoother, meets consumers' demand for high-quality Pu'er tea, and increases the yield of one tea and two leaves.
