山东省引种茶树已有14年。1979年茶园达8万亩,产茶2.2万担,高产茶园亩产有达四、五百厅的。在日照、胶南、莒南等十多个县市茶树已成为部分社队重要的经济作物之一。山东省处于暖温带,气候条件属于茶树要求的最下限。每年都有轻微冻害,七十年代则几乎每隔二、三年有一次大冻,周期性冻害已成了茶树的“例行灾难”。
Shandong Province introduced tea tree for 14 years. In 1979, the tea garden reached 80,000 mu and produced 22,000 teas. The yield of high-yield tea garden reached four or five hundred. Tea trees in over a dozen counties and cities such as Rizhao, Jiaonan and Taonan have become one of the important economic crops for some of the communes and communes. Shandong Province is warm temperate zone, climate conditions are the minimum requirements of the tea tree. Every year there is a slight frost damage, and in the seventies there was a major freeze almost every two or three years. Periodic frost damage has become a “routine catastrophe” for tea trees.
