Total developmental cycle of tea plant
The whole life period of tea tree is from seed germination to senescence and death.
According to the growth and development characteristics of tea plant, it can be divided into four biological age periods, namely: seedling stage, juvenile stage, adult stage and aging period.
Seedling stage: from seed germination, seedling unearthed to the formation of standing bud at the end of the first growth, it is the seedling stage. Generally speaking, the seeds began to germinate in March of that year and lasted for about 4-5 months until July. At the seedling stage, attention should be paid to keeping the soil loose and moist, so that enough air and water can be obtained for seed germination.
Infancy: from the first growth of tea seedlings to the first gestation of flowers and fruits, this period is called infancy. It usually lasts 2 to 4 years. The physiological function of tea plant is very active in its infancy.
Adulthood: from the first gestation of flowers and fruits to the first natural regeneration of tea trees, it is an adult. This period lasted for about 30-40 years. It was properly managed and the time could be extended. Tea trees grow most vigorously in adulthood, and their production reaches its peak. In adulthood, such as high level of water and fertilizer, good collection and cultivation management, it can generally achieve a sustained high and stable yield of more than 20 to 30 years.
Aging period: from the first natural regeneration of the tea tree to the death of the whole tea tree, it is the aging period. Generally, it is more than ten to a hundred years old.

Light pruning and Deep pruning of mature Tea trees
Light pruning (1) Light pruning: the purpose of light pruning is to promote the germination and growth of tea buds, increase production density and enhance the growth of tea trees. it is an indispensable technical measure to create and cultivate good picking surface. The degree of light pruning is to cut off 3-5 cm of branches and leaves on the surface, or you can cut off the autumn shoots of last year, leaving summer shoots. In the form of light pruning of small and medium-sized leaf tea trees, it is appropriate to cut the surface into an arc, which can increase the width of the picking width and is beneficial to increase the yield per unit area. For young and adult tea trees, light pruning can be carried out every year or every other year.

Initial management measures after tea planting
The ability of direct seeding or transplanting tea seedlings to resist natural disasters is weak, so it is necessary to cultivate and manage them carefully in order to ensure the robust growth of tea seedlings, especially in the first and second years. At the same time, the growth of tea plant is continuous for quite a number of years, such as extensive management in the early stage, poor seedling growth or low survival rate, serious lack of trees, which will inevitably affect the later growth, resulting in low yield per unit area. therefore. The focus of the initial management is to carefully protect the seedlings and ensure the whole seedlings and strong seedlings. The tasks of the first year can be summarized as follows: drought resistance, anti-freezing, weeding and fertilization, and filling gaps in seedlings. In addition, straight
