我国低产茶园面积很大,以亩产干茶低于50斤为标准约500万亩,占茶园总面积30％左右。我省是老茶区,127万亩投产茶园平均单产仅70斤左右,低于三十年前世界平均单产水平,与国内江苏、浙江等省相比较,差距也不小。我省茶叶单产低,其中一个重要原因就是低产茶园占的面积大,据霍山县调查,低产茶园占全县茶园总面积的44％;名茶之乡、全国第一大产茶县一歙县,30万亩茶园平均单产长期稳定在60斤左右的低水平线上。山区
The area of low-yielding tea gardens in China is very large. About 500,000 mu is the standard of less than 50 kg of dry tea per mu, accounting for about 30% of the total area of tea gardens. The province is an old tea plantation. The average output of 127 million mu of tea plantations is only about 70 kg, less than the world average of 30 years ago. Compared with the provinces of Jiangsu and Zhejiang, the gap is not small. Tea production in our province is low, one of the important reasons is that the area of low-yielding tea gardens is large. According to the investigation in Huoshan County, the low-yield tea gardens account for 44% of the total area of tea gardens in the whole county; the hometown of famous tea, , 300000 acres of tea plantation average long-term stability in the low level of about 60 pounds.
