in recent years, the rapid development of vegetable industry in Yunnan Province, the scale of planting and sales network continues to expand, not only sold in Shenzhen, Guangzhou, Hongkong, Nanning, Taiyuan, Hangzhou and other more than and 130 large and medium-sized city, but also exported to Thailand, Singapore, South Korea, Malaysia, Indonesia, Vietnam and other Southeast Asian market, and with the development of vegetables industry, vegetable production area transportation, cardboard boxes, foam boxes, plastic boxes, tape, nets, quilts and other related logistics and service industry has also been rapid development of vegetable production and marketing has become an important way for the development of export-oriented economy in Yunnan province and to increase the income of farmers. But in expanding the scale, speed up the vegetable production process, often have a surprising number of waste leaves, and grade products such as wilting, semi rotten, insect bites, serious injury, deformity, lesion, unsalable vegetables and other produce, making a large number of leaves resources are wasted, and cause serious pollution to the the environment of vegetable waste has become the main source of environmental pollution in vegetable production area.  
    Tonghai County, Yuxi city is one of the main vegetable production bases in China, included in the Yunnan Province, no plan of action demonstration county vegetable pollution, mild climate, moderate rainfall, flat fertile land, suitable for a variety of vegetables, vegetable industry has become a leading industry in Tonghai County, the majority of farmers to increase income. Tonghai County daily production of various types of more than 4000 tons of vegetables, at the same time, nearly 1000 tons of waste leaves every day, about 60% of these wastes by professional personnel to removal of county and township landfill waste leaves plant, about 30% farmers were dumping litter on the roadside ditch and field. A lot of leachate of waste leaves landfill and roadside pile generated direct pollution of surface water and groundwater, a direct threat to the Yunnan lake is located in Tonghai County nine of Qilu; at the same time, but also serious pollution of the Nanpanjiang River bank Nan River, brought great pollution to the lower reaches of the Pearl River system. According to the Yunnan provincial government comprehensive management of water pollution in Qilu Lake site office conference, 2011, director of the Yunnan provincial science and Technology Department office will be audited by “ waste utilization technology research and demonstration project of &rdquo leaves resources project. The project to take the lead unit of Tonghai County Science and Technology Co., for project funding, a total budget of 53 million 240 thousand yuan, which raised and local matching funds 25 million 240 thousand yuan, 18 million yuan of bank loans, the provincial science and technology funding for 10 million yuan. Aiming at the problem of the treatment project of Tonghai County waste leaves resources, pollution of Tonghai Qilu, Nanpanjiang River and other rivers, farmland environment of more than 1 thousand tons per day of waste leaves processing, R & D, manufacturing to adapt to a number of independent intellectual property rights of the supporting equipment and the product formula, the corruption leaves from waste the leaves are separated after crushing, solid-liquid separation processing and production of pure natural organic fertilizer, not corruption leaves after crushing, dehydration, and then dried to produce powder feed leaves.  
    in March 17, 2015, Yunnan province science and technology key project “ waste utilization technology research and demonstration project of &rdquo leaves resources; (Project No. 2011AB009) by the provincial science and Technology Department of Finance and project acceptance. The project construction enterprise workshop of 19762 square meters, covers an area of 60 acres, and two waste leaves dehydration production line, 24 sets of crushing plant, organic fertilizer production line workshop, drying workshop vegetable powder production line, automatic packing and palletizing production line, achieve the daily processing 1000 tons of waste leaves, with an annual output of refined organic fertilizer more than 60 thousand tons, vegetable powder production capacity of over 9000 tons. At the same time supporting the completion of an average processing capacity of 900T/d sewage treatment works. During the implementation of the project, the company achieved sales revenue of 25 million 455 thousand and 400 yuan, the product sales rate of 100%. The company production of “ James ” organic fertilizer quality inspection report shows that the quality of the products have reached or exceeded the agricultural industry Chinese organic fertilizer product quality standards, the main supply Yunnan major fruit and vegetable planting base, the main economic fruit and vegetable coverage of Yunnan province Yuxi City, Honghe Prefecture, Xishuangbanna Prefecture, Chuxiong Prefecture and other areas. During the implementation of the project, the production process and related equipment has been 15 patents, including invention patents, utility model patents 10, the appearance of the patent of 3 items. The processing of 24 patents, including 5 invention patents, utility model patents 15, 4 design patents; won the "Yunnan Province fertilizer official registration certificate", registered “ Zhan ” trademark, enterprise through the GB/T19001-2008/ISO9001:2008 standard quality management system certification; in 2014, the company was “ &rdquo approved high-tech enterprises; identification. After the treatment of water to meet the national "urban sewage treatment plant pollutant discharge standards A standard" (GB18918-2002) emission requirements. Compared with the traditional way of the project before the implementation of waste leaves and garbage mixed landfill leachate, the average daily reduction of 800 tons, annual reduction of 292000 tons, effectively reduce the leaves in mountain landfill and its downstream pollution waste and reduce environmental pollution problems in Tonghai County, vegetable waste brings, greatly reduce the Qilu Lake basin and the South Pan River system ecological pressure. Waste utilization technology research and demonstration leaves resources, provide a strong scientific and technological support for the sustained and healthy development of vegetable industry, has achieved significant ecological benefits and economic benefits.
