How to grow green tea

1. Climatic conditions \ x0d \ a. Temperature When the average temperature of day and night is stable above 10℃, tea buds begin to sprout and spread gradually. In the growing season, the monthly average temperature should be above 65438 08℃, and the optimum temperature is 20~27℃. The annual effective accumulated temperature suitable for growth is above 4000℃. If the average temperature is higher than 35℃ for several days, accompanied by drought, the branches will wither. \x0d\b, the influence of light on tea trees is mainly the intensity and properties of light. Tea tree has the characteristics of shade tolerance, and likes weak light irradiation and diffuse light. From the absorption spectrum analysis of chlorophyll, the blue-violet light with shorter wavelength is the most, while the diffuse light is mainly blue-violet light with shorter wavelength. Therefore, there is a foundation for tea trees to grow well under diffuse light conditions. \x0d\c, rainfall and humidity The suitable rainfall for tea trees is 1000 ~ 2000mm per year, the monthly rainfall in the growing season is above 100mm, and the relative humidity is generally 80~90%. The relative water content of soil is 70~80%, and such rainfall and humidity are most suitable for the growth of tea trees. \x0d\ II。 Soil conditions \x0d\ Red soil, yellow soil, sandy loam soil and brown soil are all suitable for tea tree growth, and the soil structure requires good water retention and water permeability. There is no hard soil layer at the upper depth of 1m, and the soil is required to be acidic with a PH value of 4.5-6.5 (4.5-5.5 is the most suitable). Tea tree is a calcium-loving plant, with calcium content below 0.2% and groundwater level below1m. Acidic soil is especially suitable for growing tea because it provides suitable conditions for the growth of tea trees. The root juice of tea tree contains a variety of organic acids, which provides an ideal environment for soil and endows tea tree roots with fungi, thus improving the nutrition and water conditions of tea tree. \x0d\ III。 Topographic conditions \x0d\ The slope is less than 30℃ and the altitude is below 1500m; Most famous teas in China are produced in mountains and rivers; The basis of "high mountain produces good tea" is not only high mountain and foggy, but also large temperature difference, more diffused light, short sunshine time and high humidity, which is conducive to improving the aroma of tea, good taste and good tenderness. But this is also the result of the comprehensive influence of various environmental factors. The higher the mountain, the better. In fact, good tea is also produced in the flat land.
