Air quality is a national secondary standard. Sunshine belongs to the eastern monsoon region. It is hot and rainy in summer and cold and rainy in winter. Because of its proximity to the coast, it is significantly affected by the ocean. Compared with other inland areas in the same latitude, the temperature difference between the four seasons is small, so the temperature in summer and winter is moderate.

After the jam is cooled, put it into a sterilized glass bottle and store it as soon as possible. In recent years, Chenye Town of Donggang District has highlighted the highlights of blueberry planting industry, and established a blueberry development mechanism with standardized land conversion, large-scale enterprise development, and “three-in-one” standardization of base production, which has effectively promoted the standardization and scale of agricultural industry. Development of regionalization, specialization, branding and ecologicalization. At present, the whole town's organic blueberry planting has reached 9,600 mu, and it has been awarded the title of “Shandong Province's Famous and Special Economic Forest Blueberry Township”. Strengthen the construction of the base and expand the scale of planting. Chenyu Town plans to focus on the 5 square kilometers blueberry key development zone, and builds a blueberry industrialization development base integrating scientific research, seedling cultivation, intensive processing, ecotourism and leisure harvesting in stages, and has developed Shiwanggou and Xiacaozhuang. There are 10 major blueberry production bases such as Xishanggou. There are 13 villages and more than 4,000 households engaged in blueberry production and operation. The town has successively introduced Qingdao Wolin Modern Agriculture Co., Ltd., Rizhao Dasen Agricultural Science and Technology Development Co., Ltd., Rizhao Bokang Blueberry Ru0026D Center, Rizhao Meilu Agricultural Co., Ltd., etc., and invested a total of 200 million yuan to build an organic blueberry base. Promote unified management of “standardization”, implement one-stop production, processing and sales, and create a modern agricultural production model.

The blueberry fresh fruit produced has passed the China Green Food Certification. Japan JAS organic food certification, EU GAP organic food certification, the current production base six. Introduce support policies to promote industrial development. Chen Yuzhen awarded 20,000 yuan and 50,000 yuan to the villages that develop blueberries 200-500 mu and more than 500 mu, and the village cadres subsidized 10%; invested more than 3 million yuan to build roads, drill wells and repair ponds for blueberry enterprises. Development and enterprise cultivation lay the foundation. Chen Yuzhen also established a professional cooperative to expand the scale of the industry. Established blueberry professional cooperatives, strengthened production guidance, credit support, marketing; built blueberry research institutes, strengthened technical guidance and promotion and application, realized blueberry planting technology sharing in the whole town; and relied on planting bases and leading enterprise marketing networks to expand market share and form Both production and sales are booming.
