Organic agricultural products are pure natural, pollution-free, safe and nutritious foods, which can also be called "ecological foods". According to the principle of organic agriculture and the production methods and standards of organic agricultural products, it is produced and processed, and has passed the certification of organic food certification institutions. Its principle is that in the closed cycle of agricultural energy production, agricultural resources are used in the whole process, rather than non-agricultural energy (fertilizers, pesticides, production regulators and additives, etc.). ) to influence and change the agricultural energy cycle. The production mode of organic agriculture is a production mode that uses four production factors: animals, plants, microorganisms and soil, and does not break the biological cycle chain. The difference between organic agricultural products and other agricultural products: (1) It is forbidden to use synthetic substances such as pesticides, fertilizers and hormones in the production and processing of organic agricultural products, and genetic engineering technology is not allowed; Allow other agricultural products to use these substances in a limited way, and do not prohibit the use of genetic engineering technology; (2) Organic agricultural products have strict regulations on land production and transformation. Considering that some substances will remain in the environment for a long time, it will take 2 ~ 3 years for the land to produce other agricultural products, but there is no requirement for the land change period to produce green agricultural products and pollution-free agricultural products. (3) The quantity of organic agricultural products must be strictly controlled, requiring a fixed plot and a fixed output, while other agricultural products do not have such strict requirements.
