Widely promote the introduction of south tea to the north.

After the successful trial planting of tea seedlings in Qingdao, all parts of the country followed suit, from Inner Mongolia in the north to Shandong in the south, and began to plant tea seedlings on a large scale, among which Linyi in Shandong was the best. /kloc-in the winter of 0/958, Shandong Provincial Forestry Department and Linyi Forestry Bureau purchased more than 5,000 kilograms of tea seeds from the southern tea area, and put them indoors for cooling without any treatment. 1959 spring distribution to Linyi Rizhao Dashawa Forest Farm, Platform Nursery, Mengyin Daigu Forest Farm, Pingyi Wanshougong Forest Farm, Mingguang Temple Forest Farm, Yishui Shangyu, Yiyuan Poqiu, Mengyin Gongjiachengzi, Qianchengzi, Qingdao Zhongshan Park. At that time, due to the lack of planting experience, effective management was not carried out in time after emergence, which led to the withering and death of most seedlings due to freezing and drought. Qingdao Zhongshan Park, with good ecological conditions, can survive normally due to careful management.

1965 In the spring, Comrade Tan Qilong, who was originally from the south and worked in the south, found the tea garden planted in 1959 Zhongshan Park and tasted the tea, which was superior to the southern tea. Subsequently, he instructed the Shandong Provincial Department of Commerce to strictly select the terrain and conduct small-scale trial planting. In the autumn of the same year, Chen of Shandong Sugar, Tobacco and Alcohol Company came to Linyi to discuss tea planting with the scientific and technical personnel of Linyi's commercial and forestry departments. Linyi City Commercial Bureau and Forestry Bureau also specially dispatched five people, namely Wang, Qi, Zang Xiefu, Xia Jianli and Guo Yongtian, to form Linyi City Tea Planting Leading Group, with Wang as the team leader. The tea planting team carefully summed up the experience and lessons of the first tea planting, and with the support of the provincial non-staple food company, introduced tea seeds from Zhejiang and Anhui for wintering in sand storage. 1966 In the spring, more than 20 brigades planted 90 mu of tea gardens in Rizhao, Juxian, Mengyin, Feixian and Yishui counties, and planted 7 mu in Rizhao for the first time.

1966, the trial planting in Linyi, Shandong Province was successful.

1967, the tea planting leading group further summed up the experience and took effective management measures, and planted 385 mu in 6 counties, with a survival rate of 308 mu and 80%. Since then, it has officially opened the prelude to the "South Tea to the North" in our city. By 1976, all the counties in the whole district 13 have planted tea gardens, with a total area of 46,354 mu. In order to promote the development of tea production in the whole region, 1978 established Linyi tea experimental station and regional tea association, specializing in the research and guidance of tea production.

1972 September 16, People's Daily published a report on the success of "Southern Tea Introduction to the North" in Shandong Province. 1973 10 The Ministry of Agriculture and the Tea Research Institute of the Chinese Academy of Agricultural Sciences held an experience exchange meeting in Rizhao County, Linyi, six provinces (regions) of Shandong, Tibet, Xinjiang, Shaanxi, Hebei and Liaoning. The experts attending the meeting thought that the "South Tea Delivery to the North" in Shandong Province was a success. This conclusion breaks the long-standing theory that tea cannot grow north of 30 degrees north latitude. Especially, according to the characteristics of Yimeng green tea in our city, the "regional field cultivation method" was created, which was affirmed by China Tea Culture (a textbook for colleges and universities) as a cultivation method suitable for northern tea areas. 1978 national tea zoning conference, southeastern Shandong was included in Jiangbei tea area, and Linyi was designated as a tea production base by the provincial government. In 20 13, "Yimeng green tea" was certified by the Ministry of Agriculture for geographical indications of agricultural products. In 20 15, the brand value of "Yimeng Green Tea" reached 668 million yuan, and Linyi Yuya Tea Co., Ltd., Linyi Yimengchun Tea Co., Ltd., Linshu Chunshan Tea Farm, Shandong Mengshan Longwu Tea Co., Ltd., Shandong Yimeng Green Tea Co., Ltd. and lanshan district Taigong Modern Agriculture emerged. By 1978, the tea garden area in the whole province reached nearly 7300 hectares. Later, high-yield tea cultivation pilots were arranged in Rizhao, Jiaonan, Wulian and Rongcheng, which promoted the increase of tea yield.

Linyi belongs to warm temperate humid monsoon climate, with abundant sunshine and rainfall, distinct seasons, large temperature difference between day and night, beautiful scenery and good landform. Known as the "high mountains and high waters", it has superior natural conditions and a good ecological environment. The soil is rich in organic matter and mineral elements, which is especially suitable for producing high-quality tea. Our city is a high latitude tea-producing area. The overwintering period of tea trees is longer than that in the south 1 ~ 2 months. The temperature difference between day and night is large, and the photosynthetic products of tea trees accumulate more. The fresh leaf content of tea tree is obviously higher than that in the south. The unique climate and geographical conditions make the Yimeng green tea soup produced in Linyi bright green in color, with a stretched leaf bottom, a rich chestnut flavor and a mellow aftertaste. Rich in vitamins, minerals and trace elements beneficial to human body, it is known as "thick leaves, good internal quality, strong taste and high aroma", which has won unanimous praise from tea experts at home and abroad and the favor of consumers. By the end of 20 15, the tea garden area has increased by 90,000 mu, and the total output of dry and coarse tea is 3 100 tons. The main products are green tea, black tea, yellow tea and white tea, among which the total output of famous tea is 1909 tons, accounting for 6 1.6%, and the output value of famous tea is 370 million yuan.

1998 Rizhao municipal government proposed to build the first green tea base in jiangbei, and widely plant tea. At present, the tea garden area in Rizhao Green Tea Area has reached120,000 mu, accounting for more than half of the tea garden area in the province, with an annual output of 1500 tons, accounting for more than 50% of Shandong Province. It is the largest green tea production base in Shandong Province, with output for six consecutive years. Among them, Jufeng Town 1000 mu of organic tea in Donggang District has passed the certification of EU International Organic Food Development Center and obtained the EU market "passport".

1966, the trial planting in Linyi, Shandong Province was successful.

Junan green tea area is a typical green tea production base in Linyi. 1978, Junan green tea was evaluated by Tea Research Institute of Chinese Academy of Agricultural Sciences as having high-quality characteristics of "thick leaves, resistance to brewing, high aroma and strong taste". At present, the tea garden area in Junan County has reached more than 30,000 mu, with an annual output of high-quality Junan green tea 1 10,000 kg.

1995 in the second national exposition, five varieties of Junan green tea area won two gold medals and two bronze medals, representing Shandong famous tea in the 29th World Agricultural Expo. 1997 was recognized as "China famous brand product" at the 3rd National Agricultural Expo, and was approved by China Green Food Development Center to use the "green food" logo. Products are sold to Beijing, Tianjin, Harbin, Jinan, Qingdao and other large and medium-sized cities, which are deeply loved by consumers and have broad development prospects.

After 1964, the trial planting base was transferred to Laoshan District, Qingdao. At the beginning of the trial planting, because of the low survival rate of seedlings, it was impossible to plant them in a large area. In the middle and late 1990s, Qingdao Municipal Government formulated supporting policies, provided financial support and technical guidance, and encouraged farmers to break the traditional planting structure and improve tea planting methods.

In May, 2004, the first Laoshan Tea Festival in Qingdao was successfully held, with more than 60 varieties of Laoshan Tea participating. Ten famous teas, such as Laoshan Wan Li Jiangcha and Laoshan Yunwu Tea, sell well at home and abroad, and the research on Laoshan tea culture is also in the ascendant. At present, the tea planting area in Laoshan District is 12000 mu.

In recent years, there have been successful cases of introducing tea from south to north in northern China. Due to the climate, soil and cultivation techniques, a general planting situation has not been formed. The most recent one was the successful trial planting of tea trees in Yujiawanzi Village, Wangyefu Town, Harqin Banner, Inner Mongolia.
