Detailed Explanation of Tea Tree Variety Regionalization: How Suitable Varieties Are Laid Out in Each Region
Research work on how tea tree varieties are distributed across different regions and how their suitable planting areas should be divided. China's tea regions are vast, spanning from 18°-38°N, 94°-122°E. In terms of vertical distribution, the highest extends to mountains at an altitude of 2600m, and the lowest to low hills at an altitude of only a few meters. The genetic characteristics of tea tree varieties and latitudinal zonality across regions give rise to a certain degree of zonality in tea types and quality styles. Tropical or southern subtropical regions in the south are suitable for the growth of arbor-type large-leaf tea tree varieties and are suitable for producing

What are the excellent tea plant varieties? Introduction to common varieties
Breeding and promoting excellent tea plant varieties is a fundamental measure for improving tea quality and yield and increasing the economic benefits of tea growing. A large amount of production practice and scientific research results prove that selecting excellent tea plant varieties has multiple effects in tea production: First, it can increase yield. Tea yield is determined by comprehensive factors such as the number and weight of buds and leaves per unit area, the growth speed of buds and leaves during the annual growth period (cyclicity), and the length of the vegetative growth period. Under the same conditions, different varieties have different yield factors, so yield

Key points of tea cultivation: selecting improved varieties and reasonable close planting
1. Selecting improved varieties Seeds (seedlings) are the basic means of production in tea cultivation, and any cultivation method is built on the improved varieties of a given period. Since the 1980s, tea cultivation has entirely adopted the close-planted, dwarfed, no-tillage method. Because individual space is reduced and population density increased, it is all the more necessary to match this with suitable improved varieties in order to achieve the desired results. For example, Fuding Dabaicha, Qianmei 101, Qianmei 303 and others are all fine tea varieties suitable for close planting. 2. Collection and
