Abstract:

According to the characteristics of the agricultural ecosystem and farming and breeding system, this paper summarized the circular agriculture mode of integrated planting-breeding which combines the planting industry with pig breeding industry or herbivorous animal breeding industry and the circulation pattern of rice field planting and feeding. This paper focused on the application status of ‘pig-biogas/ fertilizer-farmland planting system’, ‘pig-biogas/fertilizer-garden planting system’, ‘pig-biogas/fertilizer-grass’, ‘pig-biogas/ fertilizer-algae’, and ‘forage(straw)-herbivorous animal breeding (cattle, goat)-biogas/ fertilizer-planting system’, and ‘rice-fish’ farming, rice-duck symbiosis, rice-shrimp symbiosis and other recycling modes. It pointed out that feed conversion and utilization of breeding wastes are the key links to regulating nutrient flow in the integrated planting-breeding circular modes. Referring to the crop species and nutrient requirements of the planting system, the characteristics of feed quality requirements of the breeding system and the nutrient absorption ability of the planting system to the breeding wastes, to reasonably allocate the biological structure and time-space structure of the integrated planting-breeding system, and improve the nutrient recycling efficiency of the planting-breeding system are the key points to realize the planting-breeding balance. Based on the traditional circular agriculture mode, it is necessary to innovate and develop the environmental protection planting-breeding circular agriculture mode and construct a comprehensive management system of nutrient resources of integrated planting-breeding circular system, which can be the principal way for realizing the green production and sustainable development of planting industry, and livestock and poultry breeding industry in China.

Key words: integrated planting-breeding, circular agriculture mode, planting-breeding circular agriculture, nutrient management, planting-breeding balance
