There are 92 species of wood plants, 475 species of medicinal plants,11species of edible plants, 55 species of industrial plants and 6 species of agricultural and medicinal plants. By the end of 2007, the annual grain planting area reached 90,800 hectares, oil planting area 1.600 hectares and vegetable planting area 0.850 hectares. The annual grain output was 4 1.500 tons, oil output was 30,700 tons, vegetable output was 1.7 1 10,000 tons, and 584,700 pigs were slaughtered. Zhongxian County is a major grain-producing county, a national lean pig base county, a rape base county, a national agricultural product processing and entrepreneurship base county and a Chongqing high-quality rice, citrus, soybean, silkworm, mustard tuber and ramie production base county. Zhongxian, a citrus city in China, is building a national agricultural tourism demonstration zone "China Citrus City". Two to three years later, a "China Citrus City" integrating production, processing, trading, sightseeing and vacation will be presented to the world. 1997, Zhongxian introduced Shigelan Three Gorges Citrus Industrialization Project with a total investment of 985 million yuan, which is the largest agricultural investment attraction project in the Three Gorges reservoir area and listed as a national standardized agricultural demonstration zone. When the project is completed in 2009, there will be150,000 mu of orchards in 23 township development bases in the county, involving190,000 farmers. The annual output of citrus in the base is 435,000 tons, of which 865.438+0% is used for processing. By then, the annual output of freshly squeezed and cold squeezed orange juice will be150,000 tons, and the annual output will be 187 billion. According to relevant personages in Zhongxian County, at present, the planting scale of citrus seedlings in Zhongxian County ranks first in the world. In June+February last year, the production line of fresh and cold orange juice was officially completed and put into production, ending the history of not producing fresh and cold orange juice in the Asia-Pacific region. Medicinal material planting Zhongxian county is located in the southwest, which is suitable for planting Chinese medicinal materials in the south. 20 10 Zhongxian Supply and Marketing Association proposed to make full use of the advantages of Zhongxian's natural elevation and integration of soil and water, and vigorously develop the plan of planting water and soil, eco-sightseeing, and increasing the income of ten thousand yuan to get rich medicinal materials. Zhongxian will build a 50,000-mu medicinal planting base in five years. Following the project of Zhongxian Citrus City, we will further improve the project of increasing farmers' income, focus on the development of medicinal materials industry, and rely on Zhongxian Hongfang medicinal materials planting professional cooperative to fully promote its innovative development model of integrated services of seed, production, marketing, research and technology. Industrial machinery manufacturing mainly relies on electromechanical enterprises such as Jinlong Shipbuilding, Jinlong Electronics, Yunhe Group and Chuanjiang Automobile, and vigorously develops machinery manufacturing, electromechanical integration and equipment manufacturing, and vigorously extends the industrial chain, expands supporting industries, enriches related industries, and realizes cluster development. Energy, chemical industry and medicine mainly rely on natural gas industry and chemical industry, the national (county) Wuhan (Wuhan) pipeline for west-east gas transmission, biofuel projects, biological pesticides, yew extraction and other biopharmaceutical projects. At present, the natural gas industry and chemical industry are developing steadily and orderly, the markets of oriental pesticides and biopesticides are expanding, and the bio-fuel and bio-pharmaceutical industries of sweet potato are becoming more and more mature, with obvious benefits. * Chongqing Conch, the largest cement production project in the west of building materials, was invested and constructed by Anhui Conch Group, a top 500 enterprise in China, with a total investment of 3.6 billion yuan. Building four production lines with a daily output of 4,500 tons of cement clinker, building a cement grinding system with an annual output of 4.4 million tons, a 36MW pure low-temperature waste heat power generation system and a special wharf with an annual throughput of 6.5438+0.5 million tons can realize an annual output value of 4.5 billion yuan. At the same time, Zhongxian County will develop calcium carbonate filler industry based on the advantages of mineral resources, build the largest carbon black production base in Southwest China based on Xingbo Chemical Industry, and realize intensive development according to the requirements of an environment-friendly society, and the circular economy has achieved initial results.
