Introduction of tea plant
The introduction of tea trees is simple and effective. Since the 1950s, the planting area of improved varieties has been expanded. For example, Yunnan big-leaf species have been introduced to Guangdong, Guangxi, Sichuan, Guizhou and other provinces, with an area of more than 1 million mu. Fujian, Zhejiang and other provinces have bred a number of excellent and high-yielding new varieties by using Yunnan big-leaf species introduced and domesticated as raw materials. New progress has been made in the introduction of tea from the south to the north. The northernmost boundary of tea distribution in China has moved from 34 °40 °N to 37 °49 °N, advancing more than 350 km northward. And successively from the former Soviet Union and Japan

Biochemical reaction induced by tea cake pathogen in tea leaves
The activities of alanine ammonia lyase, polyphenol oxidase and peroxidase and the contents of protein, proline and phenols in tea leaves infected with tea cake pathogen were studied. The results showed that in diseased leaves, the activity of phenylalanine ammonia lyase decreased, while the activity of peroxidase and polyphenol oxidase increased. The analysis of peroxidase isozymes with benzidine as matrix by polyacrylamide gel electrophoresis showed that there were four isozymes in healthy tea leaves.

Tea tree pruning requirements
Trim the tea tree to trim the crown of the tree. When light pruning is carried out, the sturdy branches protruding in the middle are 3-5 cm lower than the plane. During the winter pruning time, the low mountain tea garden was carried out around Greater Cold, and the high mountain tea garden was carried out around the Beginning of Spring.

Tea tree pruning method
Tea tree pruning is a measure to control and regulate the distribution and movement of nutrients in tea trees properly according to the natural conditions, age and growth habits of varieties on the basis of comprehensive management of soil, fertilizer and water in tea gardens, so as to make rational use and distribution of nutrients. However, it must be closely coordinated with fertilizer and water management, combined with leaf collection and retention, and pay attention to pest control in order to make tea trees recover quickly and grow well after pruning. The first pruning of young tea trees, its height and branch thickness, the strength of future branches, points

Tea clone breeding
The breeding method of combining single plant breeding with asexual reproduction to produce new varieties was adopted. Tea varieties bred by clones are called tea clone varieties or tea clone varieties. It can reflect the heredity of the mother tree, can maintain the excellent characters of the improved tea varieties, the propagation speed is fast, the propagation cycle is short, and it can be propagated by cutting seedlings at the seedling stage, and the propagation coefficient is high. Since the successful popularization of tea short-spike cuttings, tea clone breeding is the breeding method of "single plant selection-cutting propagation". Breeding prescription

Transplanting techniques of improved Tea Clone varieties
The main results are as follows: 1. Transplanting improved varieties and seedlings is generally located on terraced land, gentle slope land and flat early land, with deep soil layer, good structure, shelter from the wind and abundant water resources. 2. Land preparation will be completed 10-15 days ahead of schedule. Strip planting, border width 1 meter; require deep trench hanging trough, ditch depth 25 cm 30 cm, width 24 cm 30 cm, apply base fertilizer at the bottom of the ditch, base fertilizer mostly use rotten cake fertilizer and tea special fertilizer, 150 kg cake fertilizer and 50 kg special fertilizer per mu; after fertilization, then backfill the topsoil into the ditch to maintain the soil

Management techniques of asexual cuttage nursery of tea plant
(1) in sunny days, watering the soil once in the morning and evening within 20 days after insertion to keep the soil moist; watering once a day on the 20th-60th day, and pay attention to drainage on rainy days. (2) fertilization can be carried out 60 days after fertilization, once every 10 days, and once every 15 days after 2 months. Apply 1.5 kg urea per mu in the third month and 2.5 kg urea per mu from the fifth month, 12 piculs of water per mu; mix fertilizer and water well so as not to hurt roots and leaves. (3) Tea with shade removed

Asexual cutting Seedling raising technique of Tea Plant
1. Select the nursery to choose paddy fields or hillside gardens with convenient drainage and irrigation. The gardens planted with tobacco, hemp, potatoes and vegetables should not be used as nurseries to avoid root-knot nematodes. 2. The nursery bed is made after deep turning and raking to crush the soil, the height of the nursery bed is 10ml 15cm, the width is 100cm, and the length is determined according to the topography. The width of the ditch between the seedbeds is 40ml / 50cm, and the rotten barnyard manure is applied to 2t / mu. After mixing well with the soil of the seedbed, spread a layer of 5.

Techniques of short spike cuttings of tea trees in centerless soil
Tea tree centerless soil short spike cutting not only saves the cost than the traditional paved soil short spike cutting, but also the cutting survival rate can reach 85%, which is worth popularizing. First, Miao auxiliary land preparation (1) select the land. The nursery should be close to the water source, the soil is loose, the terrain is flat, and it is convenient for drainage and irrigation. (2) Planning. To adjust measures to local conditions, divide the district according to the natural drop of the land, and dig irrigation ditches around each district, 60 centimeters wide and 40 centimeters deep. The length of the border is generally 10 to 15 meters, and the width of the border is 1 meter. The operating ditch between the border and the border is 40 cm wide, with the border facing east.
