Abstract:
Climate conditions are one of the determinants whether an area is suitable for the growth and quality of tea plants. This study is to reveal the climate advantages of main producing areas of Banan Silver Needle Tea. Taking the Banan Silver Needle Tea producing area as an example, the climate feasibility of tea planting areas is analyzed based on the statistics of climate conditions and meteorological disasters. Considering the climate impacts on the growth and quality of tea plants as well as the analysis of main meteorological factors during the spring tea growing period, the climate suitability and climate quality grade of tea growing are quantitatively analyzed based on climate suitability theory and climate quality evaluation model. The results show that the Banan Silver Needle Tea producing area has superior heat conditions, no freezing damage in early spring, and can ensure the safe overwintering of tea trees and the early harvest and high yields of spring tea; the average climate suitability is calculated to be 0.75 during the spring tea growing period, which was counted from the picking period of one bud and one leaf, maintained at a relatively high level. The climate quality grade of spring tea is maintained between grade 2 and grade 1, leading to the result that the production of quality tea can be ensured since climate condition there is good for the quality ingredient accumulation of spring tea.
