摘　　要：以蒲江县优势主导产业柑橘为研究对象,选择“有机肥替代化肥,绿色防控代替化学防治”(简称“两替”)工程代表性的生产经营主体抽取春见柑橘样品,经过两年“两替”工程的持续实施,研究发现,2022年和2023年抽取的柑橘样品中农药残留检出情况、部分农药的检出值及有害重金属含量持续降低。柑橘基地土壤中重金属元素含量逐年下降,土壤酶活性和肥力持续明显改善,进一步说明持续推进“两替”工程,可以全面提升农产品质量安全水平,促进了农业增效、农民增收。Citrus,the dominant industry in Pujiang County,as the research object,the representative production and operation subjects of Chunjian citrus were selected through the"organic fertilizer instead of chemical fertilizer,green prevention and control instead of chemical control"(referred to"two alternatives")project.After two years of continuous implementation of the"two alternatives"project,the research results indicated that the detection of pesticide residues,the detection values of some pesticides and and the content of most harmful heavy metals in citrus samples taken in 2022 and 2023 continued to decrease.The heavy metal element content in the soil of citrus base decreased yearly,while the enzyme activity and the fertility of soil are ever-increasing,further demonstrating that the continuous promotion of"two replacement"project can comprehensively improve the quality and safety level of agricultural products,promoting agricultural efficiency an d increase farmers'income.
