The government adopts the introduction of enterprises. The government sends the poverty alleviation funds to the farmers. The enterprises transfer the farmer's land, the farmers plant the seedlings, and the enterprises give the farmers wages, develop blueberry production and processing, and lead the local farmers to get rid of poverty. The Guizhou Academy of Sciences provided the after-sales service, and the science and technology commissioners took the lead in demonstrating and giving advice to the enterprises. The government gave corresponding easing policies, and the local blueberry industry became bigger and bigger, and the scale expanded, making the company profitable and the income of the people increased. The current blueberry processing industry, in addition to providing the market with primary processing products, such as concentrated juices, beverages, and some technologically advanced companies can provide deep processing products.

The factory covers an area of ​​6,000 square meters and the workshop production equipment is 5 million yuan. It is actively joint research and development with professional technicians of Kaili College. Based on the resource advantages of Guizhou Majiang Wanmu Blueberry Planting Base, it has become a leading enterprise in local fruit wine production through the adoption of advanced technology and equipment. The company's blueberry-produced red wine is called Kaiyuanchun Blueberry Red Wine, which has a deep ruby ​​color with a fresh blueberry aroma. The mouthfeel is mellow and has a long-lasting, pleasant taste. The overall structure of the wine is balanced, the aroma is elegant, and the aftertaste long. Using advanced and precise technology, the whole process of blueberry cultivation, picking and processing is traced and traced back to ensure that consumers can drink high quality blueberry fruit wine made from high quality blueberry fruit.
