【Abstract】 The model of ecological future agriculture using biogas technology as a link in the 21st century is analyzed in this paper. In the model of ecological future agriculture, an ecology chain is formed which consists of plants, animals and microbe. As far as animal breeding is concerned, there are three kinds of animals, chicken, pigs and dogs. All of these animals are new, high-tech content and high value kinds, for example, the micro-pig, carnivorous dog and so on. The breeding area is separated into two spaces, the upper space and the lower space. The upper space is used to breed chicken, and the lower space is used to breed pig and dog. The plants in the greenhouse are also high value kinds, such as aloe, sweetgrass, colored-leaf grass and so on. And the plants in the field are black maize, red maize, colored maize, black wheat. The use of microbe refers to biogas fermentation technology. The digester is built underground. The excrement of chicken can be used as feedstuff of pig, and the excrement of pig and dog is used as material of anaerobic fermentation. The productions of anaerobic fermentation include biogas, solid waste and liquid waste. Biogas is used to heat greenhouse in winter, and the carbon dioxide produced by biogas burning can strengthen the photosynthesis of plants. The solid waste, as organicr manure, substitutes some fertilizer. The liquid waste can substitute some pesticide. The utilization of the solid and liquid waste improves greatly the quality of agricultural production. The practice of this agriculture mode in "future agriculture demonstration farm" in Qi County, Henan Province has made great success, producing good economic, ecological and environmental benefits. In conclusion, by this kind of agriculture mode the recycled use of matter and energy comes true, and agricultural sustainable development has reliable technology support.更多还原
