I want to plant a tea garden in Yunnan. Which one is suitable for the climate here?

The requirements of tea tree growth on soil were introduced. If you want to know more friends, please refer to Yuncha Grand Ceremony. Next, continue to introduce the temperature requirements of tea trees. Tea trees, like others, have an optimum temperature, a minimum temperature and a maximum temperature range.

Temperature is affected by many factors, including the change of light radiation, latitude, slope, orientation, height and so on. The minimum critical temperature tolerance of tea varies greatly among different varieties. Generally, the middle and small leaf varieties of shrubs have strong low temperature tolerance, while the large leaf varieties of trees have weak low temperature tolerance.

Such as shrub-type Longjing species and Qimen species, can tolerate the low temperature of-12℃ to 16℃; Xiaoqiaomu Zhenghe Dabai tea can only withstand the low temperature of -8℃ to 10℃; However, the tree-shaped Yunnan big leaf species will be damaged at about -6℃.

Therefore, the minimum temperature of tea tree growth is defined as -8℃ to 10℃, while the minimum temperature of big leaf species is defined as -2℃ to 3℃.

The low temperature tolerance of the same variety is different at different ages, and it is weak at seedling stage, juvenile stage and senescence stage, and strong at growth stage. The cold tolerance of tea trees in the same tea garden is often stronger in winter than in early spring, which is why the "cold spring" will reduce the tea yield.

The influence of high temperature on the growth of tea trees is the same as that of low temperature, and the duration of high temperature determines the degree of damage of tea trees.

Generally speaking, the highest temperature that tea trees can withstand is 34℃-40℃, and the critical temperature for survival is 45℃. Practice has proved that sudden low temperature or high temperature often does the greatest harm to tea trees.

The optimum temperature of tea tree refers to the most vigorous and active temperature of tea tree, which is about 25℃. The biological threshold temperature of tea tree is 65438 00℃.

Fengqing long leaf tea, Fengqing species. Arbor-type, sexual reproductive line variety. The tree is spread out, with strong growth potential and high branches. The leaves are oval, cross-inserted, green, convex, soft, and the leaf margin is microwave. The buds are green, plump, hairy, fertile, tender and easy to pick. Tea-picking period is from the first ten days of March to the end of 1 1 month, and tea is picked 25-26 times a year. The sample steamed with one bud and two leaves contains 30. 19% of tea polyphenols, 34.19 mg/g of catechins, 2.90% of amino acids, 3.56% of caffeine and 45.83% of water extract. Pu 'er tea is fat, oily in color, bright red in soup color, soft in leaves, with exposed white hair, high in aroma and strong in taste. My ancestral home is Fengqing County, Yunnan Province. It is mainly distributed in tea areas in western and southern Yunnan, and 1984 has been approved as a national fine variety.
