摘　　要：针对四川丘陵区气候资源与农业类型,选择合理的生态循环农业模式,开展养分平衡管理,是实现四川丘陵区农业绿色发展的重要途径。本研究以四川蓬溪县为例开展实证分析,为川东丘陵区生态循环农业发展提供科学依据。结果表明,依据大田作物和果园目标产量、目标施N量,测算有机肥(沼液)的施用量,项目区产生的畜禽粪便和沼液可全部在区域内就近循环利用,化肥N替代率达31%~62%。依据项目区作物和果树种植基地的粪污有机肥替代测算,项目区域尚有一定的畜禽承载潜力。该种养循环模式结合当地的主导优势产业,使种养废弃物就近科学合理利用,减少了农业面源污染的风险。最后就川东丘陵区发展生态循环农业的经营机制和发展路径进行了分析,该模式为川东丘陵区开展循环农业提供参考。It is an important way to realize green development of agriculture in Sichuan hilly areas by selecting a reasonable ecological circular agriculture model according to local climate resources and agricultural types and carrying out nutrient balance management.This paper took Pengxi County of Sichuan as an example to conduct the empirical analysis,aiming to provide a scientific basis for the development of ecological circular agriculture in the hilly areas of eastern Sichuan.The results show that,based on the target yields and target nitrogen(N)application rates of crops and orchards,the application amount of organic fertilizer(biogas slurry)is calculated.The livestock and poultry manure and biogas slurry,which are produced in the project area,could be recycled within the crop fields and orchards,and the replacement rate of chemical fertilizer N could reach 31%-62%.Based on the calculation of the manure and organic fertilizer replacement in crop fields and orchards,the carrying capacity of livestock in the project area still has a certain potential.The model combines the local leading and advantageous agricultural industries,uses local planting and breeding wastes scientifically and rationally,and reduces the risk of agricultural non-point source pollution.Finally,the analysis of the management mechanism and development path of ecological circular agriculture in this study could provide an example for the development of circular agriculture in the hilly areas of eastern Sichuan.
