Can kudingcha be planted in the north? Can you freeze to death in winter?
Kuding tea is one of the traditional natural health drinks in China. The color is cool, slightly bitter and slightly sweet, and the flavor is unique. It can be used to make drinks and has great medicinal value. Meteorological conditions for planting Kuding tea;
1. 1 temperature
Kuding tea likes warm and humid, and belongs to neutral shade evergreen broad-leaved tree species. It is required that the monthly average temperature in the planting area should be above 15℃ and the annual average temperature should be 12 ~ 28℃. Temperature can determine the growth period of Kuding tea. When the daily average temperature is higher than 65438 00℃, Kuding tea begins to germinate and spread gradually. When the daily average temperature was 15 ~ 20℃, the growth rate of Kuding tea was accelerated. When the average temperature is 20 ~ 30℃, Kuding tea grows most vigorously, but its leaves are prone to aging. Daily average temperature > 35℃ or 36℃ or 65438 0.2 precipitation.
Water is the raw material for photosynthesis of Kuding tea, and rainfall and humidity conditions directly affect the yield and quality of Kuding tea. While picking tea, new buds keep sprouting. When tea leaves are picked one by one, sufficient water supply is needed. The suitable annual average precipitation of Ilex kudingcha is 1 000 ~ 1 500 mm, the monthly average precipitation should be >: 100 mm, and the annual rainy days should be >; When 150 d, the air relative humidity is kept at 80% ~ 90%, and the soil humidity is kept at 70% ~ 80%. If the growth period is dry, it will delay the growth and development time of Ilex kudingcha, and even lead to the death of seedlings and young trees. If there is too much water and the irrigation and drainage conditions in the tea garden are poor, the roots of Ilex kudingcha will die due to lack of oxygen, even the adult tea trees will age ahead of time, and the young trees will die due to rotten roots.
1.3 sunshine hours
Kuding tea likes weak light and is resistant to shade. Light has a great influence on the growth and tea quality of Ilex kudingcha. The light hours required for the whole growth and development process are determined according to the age of the tree. Generally, seedling tea trees need less sunshine days, while adult tea trees need longer sunshine hours. Kuding tea is suitable for growing in Zhongshan area with an altitude of 500~800 m and sunshine percentage of 45%.
