The Chinese green tea tree is a perennial evergreen woody plant, with various types such as tree type, semi-tree type and shrub type. Chinese green tea trees can be divided into four growth stages from the beginning of life to the aging and death (called the total development cycle): seedling stage, young age, high yield period and senescence period. The production mainly uses the benefits of the green tea trees in China during the full production period, generally 15-20 years. Strengthening the management of the tea garden can last longer.
The new shoots of Chinese green tea trees develop in the spring when the temperature reaches above 10 degrees and lasts for a certain period of time. The true leaves then unfold. When the true leaves grow (approximately 4-8 leaves), the tops form resident teeth, and after a short period of dormancy, they continue to the same year. The second round of growth. Generally it can grow for 3-4 rounds a year and the temperature drops to below 10 degrees to enter hibernation. The optimum daily temperature of Chinese green tea trees is 20-27 degrees, and the annual effective accumulated temperature is above 4000 degrees. When the average daily temperature is higher than 35 degrees, the growth of Chinese green tea trees begins to be affected.
The Chinese green tea tree is a sun-tolerant and shade-tolerant crop. It likes diffuse light, that is, blue-violet light with a short light wave. Although it is shade-tolerant, when the light is too weak, it will affect the number of green tea tree germination, tea green yield and production efficiency. Chinese green tea trees prefer air humidity of 80-90%, annual rainfall of 1000-2000㎜, slightly acidic red, yellow, gravel and other loam, which are calcium- and chlorine-avoiding crops.
