Haiqingtea is a Jiangbei green tea. Compared with other green teas, its characteristics are: thick leaves, strong brewing resistance, bright yellow color, mellow taste, sweet aftertaste, and pea fragrance. It is the best in tea. Haiqing Tea originally got its name because it was produced in Qingdao Haiqing Town. Haiqingcha can also be said to be 'haiqingcha'. This name has the characteristics of Qingdao - the minds of the sea, and deep feelings like the true meaning of the sea. It is a rare tea name and has now become a high-end gift. Synonymous with tea, Haiqing Township is the country's "million-mu tea plantation base in the north" and is known as the "Hometown of Qingdao Tea". Planting sea-green tea and frying sea-green tea has become the well-to-do road for tens of thousands of Jiaonan farmers.
Haiqing Tea was originally one of the group of Qimen leaves in Anhui Province. In 1966, Jiaonan's “Southern Tea Northward Movement and Southern Bamboo North Leading†was introduced by Haiqing Town from Anhui Province and was named “haiqingteaâ€. The variety is distributed in Haiqing Town, Jiaonan City. Currently, the tea plantation area is nearly 1,300 hectares. It is the largest latitude green tea production base in China. The average temperature of this species began to germinate at 10°C. The optimal temperature for growth was 20°C~25°C, the lowest critical temperature was -6°C~18°C, and the highest critical temperature was 45°C. The annual precipitation requirement is more than 1000mm. It is appropriate to use a deep well-drained acidic loam soil. It has grown so far. It is the green tea base with the longest growth time and largest area in Jiangbei. Now it is one of the fine agricultural projects in Qingdao, and the state-level pollution-free tea plantation base.
Haiqing Town boasts superior natural conditions and a good ecological environment. It faces the Yellow Sea in the east and is a warm temperate, humid monsoon climate with abundant sunshine and abundant rainfall. The hilly soil in the territory is slightly acidic, which is yellow-brown loam soil, rich in organic matter and trace elements. The soil particles are relatively uniform and the clay content is low, which is very suitable for the growth of tea. Due to its high latitude, Haiqing tea tree has a longer wintering period than the south. In 1-2 months, the temperature difference between day and night is beneficial to the accumulation of inclusions, rich in vitamins, minerals, and trace elements that are useful to the human body. The green tea produced here is determined by a Chinese tea expert, in which the content of catechins and amino acids is respectively It is 13.7% higher and 5.3% higher than its counterparts in the South China Tea. Its superior coastal climate and excellent environment have given Haiqing Green Tea the unique quality of “thick leaves, strong taste, pea-flavor, and brewing resistanceâ€. Moreover, it is far from the traffic arteries, there is no "industrial waste" pollution source, and the ecological environment protection is good. Therefore, Haiqing Town has become the only "Northern tea research base" named after the Shandong North Tea Research Center. Haiqing tea produced is sold well in the province, Beijing, Northeast China and other major cities in the country, and is exported to foreign markets, showing a broad prospect for development. In recent years, based on actual and scientific decisions, the local government has established tea production as the pillar industry of the agricultural characteristic economy and focused on building “the first town of Jiangbei green teaâ€.
Haiqing Town has an area of ​​78,000 mu of arable land, of which green tea has reached 30,000 mu. It produces more than 1 million kilograms of dried tea annually, realizes economic benefits of more than 150 million yuan, and farmers' income per capita has increased by nearly 3,000 yuan. The first tea factory in the province, Haiqing, was the representative of the province to introduce the experience of Nanchabeijing at the national tea conference. So far, six state-level non-polluted tea garden bases, five organic tea garden bases, 43 tea specialty villages, 30,000 acres of tea gardens, and more than 130 processing companies have been established. The annual production of dried tea is more than 1 million kilograms. The town's green tea processing enterprises have developed 12 series of more than 30 varieties, 86 tea brands have been rated as excellent, provincial excellent tea, won many awards in the "China Tea Cup" national famous tea evaluation activities, into the The ranks of the country's famous tea.

The third foreign ministerial meeting of the cooperation dialogue was designated as special tea. Haiqing Green Tea Through the implementation of organic tea, pollution-free agricultural products, food safety management system, QS certification, Haiqing Town has strengthened the standardization management of 30,000 mu of tea gardens in the town, and strengthened tea farmers' technical training and implementation of "science and technology to raise tea." To this end, they specifically hired provincial and municipal tea technical experts to serve as consultants, in accordance with the requirements of standardized production, from planting, watering, fertilizing, pruning, pest control to harvesting, in particular, rational use of drugs and field management, etc. Tea growers carry out all-round and systematic technical guidance, do a good job in supporting infrastructure construction, create shelterbelts, plant different species of living trees, create microclimate climate for organic tea production, and achieve standardized operations and high standards of production.
In order to make Haiqing Tea truly a non-pollution green drink, Haiqing Town will use a variety of forms such as radio preaching, scientific and educational film broadcasting, science and technology to understand paper distribution, and organizing tea farmers to study abroad, and will timely transfer new technologies and new methods to tea farmers. The specification of the “pollution-free organic tea plantation†plantation requires actively guiding the tea farmers to apply all the farm soil and miscellaneous fertilizers when planting and managing tea plants, and further increase the promotion and application of new technologies. In particular, the promotion and application of DND biological fertilizers and biological insecticidal lamps have been intensified. And other technical strengths. In the town's Houhe West tea production base, the company has always strictly followed the organic tea production regulations to implement standardized production, implemented pollution-free management, and all the green tea produced has reached the national pollution-free standard, and has promoted the construction of tea bases to “high, refined, and sharp†directions. In the development, Haiqing Town has also built a high-standard ecological demonstration park and tourist sightseeing park in the northern mountainous areas. A variety of preferential incentive policies have been formulated for the newly developed Chengdu Tea Plantation to promote the continuous growth of the brand tea base.
