Study Of Application And Generalization Of "4 In 1" Zoology Agriculture Mode In Nanning City

This paper had studied on popularization and application of eco-agricultural modul in Nanning by analyzing those experimental data based on investigation of the experiment situations.Popularizing "4-in-1" eco-agricultural model in Nanning not only can produce good ecological benefit and social benefit but also can bring about great economic benefit "4-in-1" eco-agricultural model ingeniously use added-ring technology of the food chain: putting pig's feces or crop straws in biogas cellar; obtaining biogas by fermentation and using it as an energy resource in lighting to solve shortage of fuel; furthermore, bio-fertilizer can be used in planting, and the residue can be used as animal feed stuff. Feeding pigs with bio-residue not only can save up forage but also can produce meat products in advance. "4-in-1" eco-agricultural modul is beneficial to achieve "Cleaning of house; High efficiency of courtyard economic; Harmless of agricultural production" most quickly and effectively. Furthermore the model can use local resources fully, can realize multi-level-conversion and benign-circle eco-system, and achieve the highest conversion ratio of energy and optimal output of products by multi-circle utilization of organic matter and regenerative action of energy resources. It has great latent force to develop "4-in-l" ecology agriculture, which is an effective way to impulse agricultural development and increase income for farmers.On the other hand, when popularizing "4-in-1" eco-agricultural model a certain number of problems prevailed. The problems are as follow: setting up organization was not reasonable currently; legislation about ecology lagged; insufficiency of effective encourage mechanism; lack of specialist; inadequate of thecapital sunk in; lower intrinsic of peasants and so on.Corresponding countermeasure aim for solving these problems are listed as follow: The development of "4-in-lw eco-agricultural model should accomplish these transitions as follow: from chasing amount to chasing quality -. from single market to domestic or international market -. from production function to compound function; from small-scale production to eco-agriculture-industrialization. Adjust the establishment of organization, and set up reasonable and effective special department. Perfect legal system and legislation of eco-agriculture. Aggrandize the input of funds, helping to develop "4-in-l" eco-agricultural model. Improve technological system of ecology agriculture. Establish evaluate standard for ecology agricultural construction, which is help for the development of eco-agriculture becoming standardization and in order. Establish encouraging policies and guarantee mechanism for promoting eco-agriculture to quickly and healthy developments, and strengthen the participation of The public. Propose "4-in-l" eco-agricultural model, and carry out ability-building positively in which ecology agriculture as center.
