摘要
通过对位于江南茶区的安徽省农科院茶叶研究所和位于江北茶区的安徽省潜山县糖岭茶场，历年春茶谷雨前产量比重与两地３～４月逐旬主要气象因子的相关性分析，得出３月中、下旬平均气温和３月中旬日照时数，特别是由它们组成的复合时段气象因子与春茶谷雨前产量比重的关系密切；并运用这些复合气象因子建立了可用于春茶谷雨前产量预报的回归方程。
he correlations between the spring tea yields and climatic factors at every ten days in March and April in two Tea Plantations were analyzed. Results showed that the spring tea yields before Grain Rain had close correlation with the mean temperature of the second and last ten days in March and sunshine hour of the second ten days in March, especially had close correlations with the complex climatic factors. A regression equation for forecast the production before Grain Rain of spring tea was established using these complex climatic factors.
