Tea plants have certain requirements for environmental conditions during the development of the system. In the long-term growth and development process, tea plants have adapted to certain environmental conditions, thus forming specific needs for certain ecological factors, and these ecological factors have become conditions suitable for their fertility.
Weather condition
Meteorological conditions have a significant effect on the growth of tea plants. Meteorological factors such as light, heat and water are particularly important. Understanding the relationship between meteorological factors and the growth of tea plants, and grasping the limits and the most suitable indicators of meteorological factors for the growth of tea plants are the basis for the development of scientific measures for the cultivation of tea plants.
Ninety to ninety-five percent of the tea plant's biomass is produced by the use of CO2 and water through the photosynthesis of carbohydrates. The formation of tea tree economic production mainly depends on photosynthesis. Illumination intensity, light quality and illumination time have a great influence on the growth of tea plants. Tea plants are shade-tolerant plants, avoid direct light, and have greater plasticity for light intensity requirements. Due to hereditary shade-tolerance habits, tea trees use better scattered light energy, and direct light can damage the protoplasm's chloroplasts and adversely affect their growth. Tea plants grow best under red and orange light; blue light has physiological significance for nitrogen metabolism and protein formation; orange light is long and has high activity for carbon metabolism and carbohydrate formation; purple light not only affects nitrogen metabolism Protein formation is of great significance, and it is directly related to some nitrogenous compounds and aroma components. Tea trees are short-day plants, and shading treatment will advance flowering and flowering. Sunshine hours have a certain effect on the early yield of spring tea, especially the germination time of overwintering buds is directly related to the sunshine hours. According to Indian studies, the daily light in the winter for six consecutive weeks for 11 hours, even if the temperature, moisture, nutrition, etc. can be met, but the tea tree still enters a relatively dormant period, if the extended light time is 13 hours, it can break some tea varieties The winter dormancy promotes the growth of tea trees and inhibits the flowering of tea trees.
