In June, the land of Jianghuai is sunny and verdant with greenery. In the 1600 acre high standard facility blueberry planting base of Happiness Coast Agricultural Manor in Huaining County, Anqing City, Anhui Province, the plump blueberries are adorned with branches, like crystal clear sapphires. Looking closely at both sides of the ridges, black drip irrigation belts crisscross each other, and drip water, fertilizer, and pest control agents into the soil at regular intervals. In addition to being equipped with this automatic integrated drip irrigation system for water and fertilizer, the base also uses a substrate composed of materials such as peat, coconut bran, and perlite for scientific cultivation of blueberries. Since entering the mature season in May, the number of tourists entering the park to pick blueberries has exceeded 4000, which not only cultivates blueberries but also grows scenery. At the same time, the company has also driven more than 20 nearby farmers to sell fresh fruits for over 5 million yuan Liu Guantian, the person in charge of the Happy Coast Agricultural Estate, said. With a blueberry planting area of 88000 acres, a comprehensive blueberry output value of 6.5 billion yuan, and more than 200 planting enterprises developing in a concentrated and contiguous manner, Huaining has become the largest county-level blueberry planting area in the Yangtze River Delta region. As a high-value agricultural product, small berries not only beautify the green mountains and waters, but also promote the local development of a full chain integrated development blueprint of "good variety breeding+large-scale planting+deep processing+picking tourism", transforming into a "happy fruit" that helps farmers increase income and revitalize rural areas. According to Lu Xiubing, the deputy director of the Anhui Southwest Comprehensive Experimental Station at Anhui Agricultural University, Huaining County is located near 30 ° north latitude, with superior ecology, humid climate, and high soil organic matter content, making it a natural base for blueberry cultivation. Natural endowment is just one of the prerequisites for a high yield of blueberries. The high-quality fresh fruits that sell well nationwide cannot be separated from scientific selection and technological empowerment. "Blueberries are relatively delicate and have high requirements for climate, soil, water quality, and pest control technologies. They require a large amount of investment and are difficult to cultivate for individual farmers." Huaining County Party Secretary Yu Xuefeng said that for this purpose, the local government has cooperated with Anhui Agricultural University, Chinese Academy of Agricultural Sciences, and other institutions to promote technological modernization and industrial intelligence, and to focus on local specialties. In the cultivation room of the Annong University experimental station, Lu Xiubing pointed to more than a hundred glass bottles on a row of shelves and introduced to reporters, "We selected multiple blueberry varieties, constantly changed the soil acidity and alkalinity, and finally screened out high-quality varieties that are suitable for the local soil." From planting more than 100 varieties many years ago, to now adjusting and updating to more than 30 good varieties such as early maturing, high-quality, and high priced "O'Neill," "Emerald," and "Lexi," Annong University experiments stand on the planting end to improve the economic benefits of blueberries, overcome the problems of low fruit yield and high disease and pest rates, and has trained local growers and technical experts for more than 3500 times, driving the county's blueberry industry. The industrial operating entities increased their income by over 30 million yuan. Huaining will apply technology throughout the entire process of planting, picking, and sales, actively promoting the digital transformation of blueberry production. In the workshop of Huaining County Rural Supply Chain Management Co., Ltd., the digital intelligent blueberry sorting and packaging equipment is busy, and the cold chain logistics monitoring and intelligent warehouse management system is operating efficiently. "We have collaborated with 200 growers in 19 townships to carry out guaranteed purchases. By integrating goods and ensuring smooth logistics, we use independent brands such as Huaining Blueberry and 30 ° North Latitude Berry to lead the 'last mile' and distribute the benefits of brand premium to more farmers." The deputy general manager of the company, Jin Jian, said. At the 7th Huaining Blueberry Cultural Tourism Festival and the 1st Blueberry Production and Marketing Conference held on the 12th, there was a wide variety of processed products with higher added value, such as blueberry enzyme solution, blueberry ice wine, blueberry cake, and blueberry dried fruits, attracting many guests to stop and discuss. To meet the growing demand of consumers for high-quality health products, the company is equipped with two precision processing workshops, which can process 4000 tons of fresh fruits annually. In the future, we will accelerate the development of blueberry health function products and launch more new products Mei Wenlong, the person in charge of Huaining Meilan Kangjia Food Technology Development Co., Ltd. who came to participate in the exhibition, said. Behind the three-dimensional industrial cluster centered on blueberries is the policy support for Huaining's scientific planning and continuous promotion. Develop a blueberry industry development plan, promote the application of blueberry anthocyanins in pharmaceuticals, cosmetics, health products, and functional foods, and deeply integrate blueberries with the big health industry; Establish a blueberry industry development service center, focusing on building a rural revitalization demonstration zone with blueberries as the main element; Integrating national, provincial, and municipal project funds to support the development of blueberry enterprises, a cumulative reward and subsidy fund of 43.95 million yuan has been realized... Yu Xuefeng stated that according to the plan, the blueberry planting area in the entire county is expected to reach 100000 mu and the annual output value will reach 10 billion yuan by 2025.
