| 摘要 | Based on the observation data of daily average temperature, daily rainfall and sunshine duration from 2005 to 2024 from the national basic meteorological station and regional meteorological station in Jingning, as well as the data of tea yield and growth period, the first picking date and quality of Huiming tea in Jingning were evaluated by the analysis of physical and chemical indicators and climate quality index of Huiming tea. The results show that in the past two decades, the first picking date of Huiming tea showed a significant advancing trend. Climate warming led to an increase in ≥0 ℃ active accumulated temperature, thus advancing the first picking date. The climate quality index of tea was “very excellent” in most years, and the physical and chemical indicators were at the special grade. Tea yield was significantly correlated with multiple meteorological factors, especially closely related to sunshine duration in early February and ≥5 ℃ active accumulated temperature from February to April. |
