Simply put, from the biochemical mechanism, there are many favorable environmental factors for the growth of tea trees in mountainous areas: high-altitude tea gardens, generally mild climate, abundant rainfall, more clouds, high humidity and large temperature difference between day and night.

First, low temperature

The relatively low temperature leads to the slow growth of tea, which is beneficial to maintain the high concentration of soluble nitrogen compounds in the new shoot tissue and is suitable for the formation of amino acids and aroma substances. Some fresh and fragrant substances were formed at higher altitude and lower temperature.

Second, high humidity.

Cloudy days and high humidity can not only inhibit the synthesis of cellulose, but also keep the tenderness of buds and leaves; Long-term moisture at the base of tea canopy is beneficial to the synthesis and accumulation of nitrogen-containing compounds and some aromatic substances.

Third, there is enough light.

The combination of solar scattered light and blue-violet light in tea garden increases, which enhances the diffusion effect and is also beneficial to the synthesis and accumulation of nitrogen-containing compounds and some aromatic substances.

Fourth, the temperature difference is large.

The larger temperature difference between day and night is beneficial to the accumulation of photosynthetic products, which increases the contents of protein, amino acids and vitamins.

Finally, the quality result of Wu Yun Alpine Camellia was formed:

Protein and amino acids: high, fresh and refreshing.

Tea polyphenols and catechins: low and astringent.

Aromatic substances: increased, forming a unique tea fragrance.
