Rice-fishing integrated planting and breeding has become an important ecological rice farming model in my country.The promotion of this model plays an important role in the adjustment of the rice industry structure in Shanxi Province,the promotion of agricultural supply-side structural reforms,and the promotion of rural revitalization.In this study,four integrated rice-fishing cultivation models,namely "rice-Yangtze River crab-fish","rice-Liaohe crab-fish","rice-shrimp" and "rice-fish" were constructed in the paddy field park.By analyzing the effects of different models on rice agronomic traits,yield and quality,monitoring the dynamics of changes in the water environment of rice fields,and conducting benefit analysis.The aim is to explore the feasibility of different rice-fishing integrated planting and breeding models and the advantages between them.The experimental results show that it is feasible to promote rice-fishing integrated planting and breeding in the Jinci area of Taiyuan City.Different integrated planting and breeding models are better than conventional monoculture rice in terms of agronomic traits and yield performance;The unit price of rice is from 12 yuan/kg Increased to 18 yuan/kg,while harvesting rice,aquatic products also increase the benefits of 3120-5716 yuan per mu for different comprehensive planting and raising models.The economic benefits of the rice-fishing integrated planting and breeding models are RMB 13563.42~15873.02,which is an increase of 133.20%~172.91% compared with conventional monoculture rice;Effectively improved the processing and appearance quality of rice,improved the nutritional quality and cooking and eating quality of rice;Different integrated planting and raising models all improved the water environment of the rice field to a certain extent The addition of aquatic animals and aquatic plants makes the operation of material circulation,energy transfer and storage in the rice field ecosystem more reasonable,and effectively reduces the occurrence of diseases,insects and weeds.Among the different rice-fish integrated farming models,the rice-Yangtze River crab-fish integrated farming model has better agronomic traits than the other three integrated farming models,and it has a stronger effect on the yield and quality of rice,and has higher comprehensive benefits,is the most suitable comprehensive rice-fishing planting and breeding model to be promoted in Jinyuan District of Taiyuan City.
