江南茶区包括长江中下游南岸的浙江、苏南、皖南、江西、湖南、湖北等地,是目前我国茶叶生产最集中的茶区。茶树为喜温的多年生植物,在日平均气温达到10℃以上时,才能进行光合作用,长出新梢和芽叶,获得产量。本文根据茶树的生物学特性,统计了江南茶区有代表性的10个气象台站日平均气温≥10℃、≥20℃、≥20℃的起止日期以及
The southern tea area includes Zhejiang, southern Jiangsu, southern Anhui, Jiangxi, Hunan and Hubei in the south bank of the middle and lower reaches of the Yangtze River. It is the tea area with the most concentrated tea production in our country. Tea tree for the temperature of perennials, the average daily temperature reached above 10 ℃, to photosynthesis, grow shoots and shoots, yield. Based on the biological characteristics of tea tree, this paper calculated the starting and ending dates of the average daily temperature of ≥10 ℃, ≥20 ℃ and ≥20 ℃ of 10 typical meteorological stations in Jiangnan tea district.
