Management of tea tree crown
1. Tea pruning is an important measure in crown management. Pruning includes stereotyped pruning in infancy, light and deep pruning in adult tea gardens, re-pruning and table cutting in aging tea gardens. The main results are as follows: (1) stereotyped pruning of young tea trees: 3 or 4 times of stereotyped pruning in young tea trees can inhibit the apical dominance of the trunk of young tea trees, promote the germination of axillary buds, increase the number of backbone branches, and quickly form a robust picking surface with a certain height. The first stereotyped pruning of ① was carried out after the cuttings were transplanted. When the transplanted seedlings are as high as 25cm

Measures to be taken after tea trees are harmed by freezing
1. All the shoots and shoots on the surface of the crown that have been scorched by freezing should be cut off, and the specific depth of pruning should be determined according to the degree of freezing. 2. The suitable pruning time is from February 15 to March 5, that is, the period from Rain Water to sting. 3. Topdressing in time: cutting off the shoots damaged by freezing will consume a lot of nutrients in the tea plant, and timely topdressing can promote the rapid recovery of tea tree growth. In general, conventional tea gardens can choose to apply 20 to 30 kilograms of urea per mu in sunny days. For example, organic tea gardens can be sprayed 10 to 20 days before spring tea mining.

Technical measures for Prevention of Heat damage in Tea trees
The heat damage of tea tree refers to the meteorological disaster which results in the reduction of tea production, the hindrance of tea tree growth or the death of tea plant under the condition of long-term high temperature and dry climate. Tea is native to the subtropics and belongs to perennial evergreen plants. It has the habit of being warm, humid, shady and afraid of drought. When the persistent high temperature and excessive drought, the red sun is hot, the rainfall is less, and the air relative humidity is less than 50%, the transpiration of the leaves is enhanced, and the water absorbed by the roots can not make up for the consumption of the aboveground part, thus withering and falling leaves of the tea tree, and even death. To prevent the heat damage of tea trees, except to choose heat-resistant tea trees.

Tea tree autumn and winter management "six-step song"
Tea tree after a year of picking, the tree body is greatly damaged, autumn and winter if timely tending work, to speed up the recovery of tree body, cultivate strong tree vigor, to win the next year tea quality and high yield is very important. Therefore, tea farmers should do a good job in six aspects. One is autumn farming. Tea tree picked spring, summer, autumn tea, fully absorb the underground nutrients, soil becomes more hardened, if fertilization at this time, is not conducive to tea tree absorption. Therefore, after the tea garden is closed and tea picking is stopped, a shallow ploughing, loosening,

Cutting propagation of tea tree
One of the methods of asexual reproduction of tea plant. A part of the vegetative organs of the tea plant was inserted into the nursery of the moist and loose red and yellow soil to form a new complete plant. The tea seedlings cultivated by cutting propagation showed similar heredity to the mother plant, and could maintain the characters and characteristics of the mother plant under the same environmental conditions. Cutting types: can be summed up as: branch cutting, leaf cutting and root cutting. ① branch cutting method includes long ear, middle ear, short ear, hoop and old stem cutting and so on. Cuttings with a complete tea branch as cuttings

Tea variety regionalization
The research work on the distribution of tea varieties in different regions and how to divide the suitable planting areas. Tea areas in China are widely distributed, ranging from 18 °to 38 °N and 94 °to 122 °E. The vertical distribution ranges from the highest to the mountains at 2600m above sea level and the lowest to the low hills only a few meters above sea level. The genetic characteristics of tea varieties and the latitude zonality of the region make the tea and quality style appear certain zonality. In the southern tropics or subtropics, it is suitable for the growth and production of tree-type large-leaf tea varieties.
