Advantages and disadvantages of ecological agriculture
Eco-agriculture emphasizes giving full play to the overall function of agricultural ecosystem, taking macro-agriculture as the starting point, and comprehensively planning, adjusting and optimizing the agricultural structure according to the principle of "entirety, coordination, circulation and regeneration", so that agriculture, forestry, animal husbandry, sideline, fishery and rural primary and secondary industries can develop in an all-round way, and all industries can support and supplement each other and improve the comprehensive production capacity.
Disadvantages of ecological agriculture:
1 is incomplete in theory.
Ecological agriculture is a complex system engineering, which needs the support of agronomy, forestry, animal husbandry, aquaculture, ecology, resource science, environmental science, processing technology and social science.
2. The technical system is not perfect.
In an eco-agricultural system, there are often many components, and there are very complicated relationships between these components. For example, the number of ducks should be considered in raising ducks in fish ponds. The number of ducks will be restricted by many conditions, such as water changing speed, pond volume, water quality, species and quantity of fish, water temperature, age and size of ducks and so on.
This policy needs to be improved in some places.
Without the support of the government, it is impossible for ecological agriculture to be truly popularized and developed. The most important thing for government support is to establish an effective policy incentive mechanism and guarantee system. Although the rural economic reform in China is very successful, there are still many areas to be improved in the implementation of eco-agriculture.

The provisions of ecological agriculture:
As an ecological product, it must conform to the standards of the International Association for Ecological Agriculture (IFOAM), such as how the product is produced, which substances are allowed to be used, which substances are not allowed to be used, and so on. In the production process of ecological products, raw materials must be ecological. If the additives used must be used in the production process, some additives are allowed to come from traditional agriculture, but not more than 25%.
Once the traditional agricultural additives are used, the proportion should be indicated in the products. Only if more than 95% of additives come from ecology can they be sold as pure ecological products. If an enterprise wants to join the "Ecological Agriculture Association" and sell its products as ecological products, it must go through 3
A comprehensive adjustment is needed in 2008.
