2020年江苏春茶减产原因分析

2020年江苏早春气温平稳上升,几乎未发生晚霜冻,茶叶产量较往年却减产10%~20%。文章利用主产区气象站历史观测资料和2020年茶叶生产相关资料,分析其减产原因,认为2020年早春气温异常偏高,开采期比常年提前10 d以上,3月17—27日最高气温基本维持在20℃以上,采摘洪峰来得早,受疫情影响引起的茶场人力不足,严重影响茶叶采摘进度,造成茶园产量降低。此外,2019年秋季持续干旱和2020年采摘期多降水过程,对茶叶生产也造成了负面影响。

Analysis on the Causes of Spring Tea Production Reduction in Jiangsu in 2020

In 2020,the temperature in Jiangsu Province rose steadily in early spring,and there was almost no late frost.The output of tea was reduced by 10%-20%compared with the previous years.The historical observation data from weather stations in the main producing areas and relevant data of tea production in 2020 were used to analyze the causes of the decline in production.It can be concluded that the temperature in early spring of 2020 was abnormally high,and the picking period was more than 10 days earlier than normal.The highest temperature was basically maintained above 20℃from 17 to 27 March.The earlier peak of picking time,and the lack of manpower caused by the Coronavirus outbreak seriously affected tea production and output.In addition,the continued drought in the autumn of 2019 and heavy rainfall during the harvesting period in 2020 also had negative impacts on tea production.
