In 2002, Huanglou Town achieved fiscal revenue of 5.59 million yuan, and the per capita net income of farmers was 3,431 yuan. Huanglou Town is an important flower town in the north of the Yangtze River and has the reputation of "the first flower town in the north of the Yangtze River". The town party committee and government follow the working idea of ??"establishing the town with flowers, strengthening the town with three industries, and opening up the town" and regard the development of flowers as a way to enrich the people and strengthen the town. The leading industry has been focused on. The flower area in the town has now reached more than 10,000 acres, and the Wanhong flower trading hall alone has an area of ??30,000 square meters. There are more than 3,000 flower professional households and 12 flower parks. It receives visitors from all over the country at all levels every year. There are nearly 100,000 leaders and visitors, and the marketing network covers more than 20 provinces, municipalities and autonomous regions across the country. The annual sales revenue from flowers accounts for more than 35% of the town's total agricultural revenue. A development pattern of "ten miles of flower streets, hundreds of acres of market, thousands of households operating, and ten thousand acres of base" has been initially formed. In particular, the successful holding of the 3rd Shandong Flower Expo and Shandong Qingzhou Flower Fair has brought huge business opportunities to the development of the flower industry. In addition, vegetables and livestock are also the town’s specialty industries. The specialty Mihe silver melon is a tribute from past dynasties. It has registered the "Miyin" brand trademark, passed the provincial pollution-free food certification, and was rated as a famous brand product at the 2001 National Agricultural Products Exhibition. The private economy has developed rapidly, and an agricultural product processing system has been formed that focuses on slaughtering and processing, freezing and refrigeration, and vegetable preservation. There are 11 refrigeration plants in the town, with an annual production capacity of nearly 30,000 tons and a storage capacity of more than 2,500 tons, ranking among the best in the same industry in the city. There are also more than 40 private enterprises such as steel ball factories, special paper factories, sand dredger processing factories, and electrical appliance factories. The construction of small towns has developed rapidly. The town government has built a new small town with complete infrastructure including postal and telecommunications, water supply and power supply, optical cable television, culture, education and health, and has begun to function as a modern carrier.
