Eco-culture refers to a kind of culture mode in a certain culture space and region, which makes different organisms grow together in the same environment through corresponding technology and management measures according to the principle of * * * complementarity between different cultured organisms, thus maintaining ecological balance and improving culture efficiency.
Ecological farming centers on one or more kinds of livestock and poultry farming, and at the same time, other related industries, such as planting, gardening and flowers, fertilizer industry or other aquaculture, are allocated to realize pollution-free discharge and organically combine resource recycling with environmental protection.
In order to ensure the normal assimilation and alienation of biota in each link of the system, the material circulation and energy flow and transformation are continuously carried out in the form of "food chain" in the ecological circulation aquaculture system. All the links in the system are closely linked, and the fluctuation of the upstream link will make the downstream link difficult to control or even lose its original balance.
At present, typical livestock and poultry ecological breeding models can be divided into three categories, namely, primary model, intermediate model and advanced model.
Among them, the primary mode is mainly to raise chickens, pigs and other livestock and poultry. The generated feces are fermented by special microorganisms and used to feed maggots and earthworms, and then the cultured maggots and earthworms are used to feed livestock and poultry. Waste from feeding maggots and earthworms is used to grow food and vegetables, which can be sold or used to raise livestock and poultry.
In the re-intermediate mode, the excrement discharged from livestock and poultry breeding is used for breeding fly maggots, the excrement after breeding fly maggots is used for raising earthworms, and the excrement after cultivating earthworms is used for planting grain and vegetables, and the produced grain and vegetables can be continuously fed to livestock and poultry. Fly maggots and earthworms can be used to raise fish and feed livestock and poultry. Microorganisms can be used to ferment feces to remove pathogenic microorganisms and odor of feces, purify the environment and water quality of barns and fish ponds, and ferment manure into fertilizer.
On the basis of the intermediate model, the advanced model adds links such as large-scale farms, orchard production, mulberry production, sericulture production, biogas digester fermentation, special aquaculture, rural domestic garbage and human excrement treatment, green vegetable production, etc., which can treat human and animal excrement more efficiently, reuse fermented excrement for many times, and produce more kinds of by-products.
