The quality of tea picking directly affects the yield, quality and growth of tea trees. Therefore, improving the picking technology and picking quality is an important measure to promote the yield and quality of tea.
 
Soil Management of 1. Tea Garden
1. Tea garden ploughing and hoeing
① Deep ploughing of young tea gardens: for the first time, spring tea is grown in April to May. Within one foot on both sides of the tea tree, shallow hoe weeds 2-3 inches, and intertillage 4-5 inches deep beyond one foot. The second time in the summer after July-August, shallow tillage weeding. For the third time, after autumn tea, intertillage will be carried out from October to November, with shallow tillage within one foot of the root and intertillage beyond one foot.
② Farming and hoeing in the youth tea garden: For the first time, during July to August when the soil plate and grass were flourishing in the late summer tea, shallow tillage was used to weed 2-3 inches within the vertical lower range of the tea canopy, and intertillage was about 5 inches deep outside the range of the tea canopy to loosen the soil and bury the grass. The second time was between October and November, shallow ploughing was carried out within the tea canopy, and between the outside of the tea canopy, digging more than 5 inches deep and burying grass.
③ Farming and hoeing in adult tea gardens: for the first time, between July and August, 3-4 inches deep is cultivated within the coverage area of tea canopy, and more than 5 inches is cultivated between tea canopy and grass is buried. For the second time, from October to December, deep ploughing was carried out to turn the soil, intertilling and weeding were carried out within the scope of tea canopy, and deep ploughing was carried out to turn the soil and bury the grass between the outside of tea canopy for 6-7 inches.
2. Water and soil conservation in tea garden: while ploughing and hoeing, attention must be paid to water and soil conservation. The following measures are mainly taken: ① Change slope land into terrace land. ② Renovate the ladder surface. ③ Protect the ladder wall. ④ Open mountain flood control ditch. ⑤ Mowing weeds and chemical weeding are used in tea gardens with large slopes.
3. Chemical weeding: Chemical weeding is an advanced and effective measure in tea garden management, which can not only reduce the damage of tea root by hoe, but also adjust labor, save labor and promote the growth of tea trees. Chemical weeding must be selected for human and animal safety, high efficiency, bottom poison, low cost, easy to use agents.

2. tea garden fertilization

Fertilizer provides the nutrients needed for the growth of tea trees, which is the material basis for the metabolism of tea tree organisms, and also the material basis for vegetative growth and reproductive growth. Therefore, fertilization is of great significance to the growth and development, yield and quality of tea plants.

1. Characteristics of tea tree fertilizer requirement: ① Continuity of fertilizer requirement. ② Phases of the need for fertilizer for tea trees. The diversity of nutritional needs. The concentration of nutritional needs.

2, tea garden fertilization technology: tea garden fertilization technology and fertilizer types, fertilization times and period, quantity, methods, land conditions, etc. are closely related, are described as follows:

The type of fertilizer: organic fertilizer is commonly used: manure, compost, manure, green manure, cake fertilizer, etc.; inorganic fertilizer commonly used are: urea, calcium superphosphate, calcium magnesium phosphorus, compound fertilizer, etc.

The number and time of fertilization: tea tree fertilization is divided into two kinds of base fertilizer and top dressing. Base fertilizer is applied once a year in November when tea leaves are close to stopping growth. Top dressing is applied twice a year, the first time is applied in May before summer tea germination, the second time is applied between July and August in the late summer tea, and the sprout accelerating fertilizer is also applied before spring tea.

③ Fertilization amount: The fertilization amount is determined according to the age and yield of tea trees, and the three elements of N, P and K are used together. The age of the tree is 1-2 years, 2-4kg of pure ammonia is applied per mu, and the ratio of N:P:K is 1:2:1; For 3-4 years old tea trees, pure nitrogen is 5-6kg per mu, and the ratio of N:P:K is 2:2:1; For 5-6 years old tea trees, pure nitrogen is 7-9kg per mu, and the ratio of N:P:K is 3:1:1:1.

④ Fertilization method: tea garden fertilization, generally use the method of ditching fertilization, soil buried cover, fertilization ditch opened in the crown edge vertical place. Fertilization ditch depth: 6-7 inches of base fertilizer, topdressing 2-3 inches deep.

⑤ Top dressing outside the roots of tea trees: add the fertilizer into clear water according to the concentration, and spray the prepared liquid fertilizer on the back of the leaves of tea trees with a sprayer to the degree of wetting. At present, the commonly used fertilizers are: urea, ammonium nitrate, superphosphate, biological fertilizer, etc.

3. tea picking

1, Young tea garden picking technology

① Take less and raise more: when the new shoots grow to 4-6 leaves, take off the terminal buds and raise more branches.

② pick high and raise low: leave 2-3 leaves on the new shoots above the pruned cut mouth, and pick the terminal buds. Those below the cut will be kept for storage and not harvested.

③ Top picking and edge raising: pick one bud at the top of the new tip and 2. three leaves, leaving 2-3 large leaves on the new pile.

④ Weak picking to raise the strong: the "pair of three leaves" with weak growth ability leave one leaf to pick two leaves, and the single leaf and the pair of two leaves are all picked.

⑤ Dense and sparse cultivation: less leaves should be left at the denser places of new shoots and appropriate vegetable buds. Leave 2-3 leaves at the sparse place of the new shoot to remove the terminal bud.

2. Picking tea trees in the prime of life

① Timely mining: when 10-15% of the new shoots grow to meet the picking standards.

② Multiple harvesting in batches: According to the size of the normal new shoots of the tea tree, the first harvesting is done, the second harvesting is done, the first harvesting reaches the standard, the next harvesting is not up to the standard, and the "single leaf" and "double leaf" that stop growing are all harvested.

Reasonable leaves: leave one leaf in spring and summer, and leave fish leaves for picking in autumn.

Quality Management of 4. Fresh Leaves

The buds and leaves should be kept intact, fresh and neat when picking. Picking should not take fish leaf scales, camellia tea fruit, old branches and old leaves, rainwater leaves, pest leaves, wind scorched leaves, purple leaves, leaves that do not meet the standards should not be picked.
