after 4 years of research and more than 100 tests, kunming successfully used floating water cultivation technology in dianchi lake to successfully cultivate more than 30 kinds of organic vegetables.
in 2006, kunming a science and technology development co., ltd. introduced ecological innovation technology, hired well-known domestic agricultural science and technology experts to form "dianchi lake floating surface cultivation of ecological vegetables, water purification," the subject of r & d experts groups, a total investment of more than 1,000 yuan, 600 acres of village side of the water to explore the "dianchi lake floating planting ecological vegetables, water purification," the project, and government departments and relevant research institutions support.

recently, the state ministry of agriculture agricultural products quality supervision and testing center and kunming university of science and chemical engineering institute of vegetables imported water samples, export water, "test report" to determine, all the indicators of vegetables qualified. the yunnan academy of agricultural sciences institute of agricultural economics and information technology, "new technology report" confirmed: yunnan fu bao agricultural science and technology development co., ltd., the use of plateau freshwater lake dianchi planted water vegetables, "is the first domestic initiative."
yunnan academy of agricultural sciences professor yang jiali said that "dianchi lake floating planted ecological vegetables, water purification," scientific research innovation is the relative business and experts, production and scientific research combined to create an environment-friendly, resource-saving modern agriculture success practice and new initiatives are the "technological revolutions" in the cultivation of vegetables from the ground to the surface.
dianchi lake is located in kunming, southwest of the city, north of kunming, south of the low topography, coupled with neglect prevention and control, so that dianchi lake has become a dirt place. especially since the eighties of last century, with the expansion of urban population, population growth, sharp increase of urban domestic sewage discharge and pollution load, due to the lagging construction of supporting pipe network of sewage treatment plant, the pollution of the pond is becoming more and more serious. the main pollution load of the lake showed a substantial upward trend, the water quality is basically five categories, inferior five categories. dianchi lake by the state council included in the focus of governance in china lakes. yunnan provincial government and kunming government have long sought to find ways to effectively manage dianchi lake pollution.
