为了了解我国荔枝和龙眼中农药最大残留限量（Maximum Residue Limits，MRLs）标准的制定情况，保障我国荔枝龙眼产业的发展，该研究以现行《食品安全国家标准 食品中农药最大残留限量》（GB 2763-2021）为依据，结合我国农药在荔枝龙眼上的登记情况，分析了我国荔枝龙眼上农药MRLs标准现状，并按农药类别列出了MRLs、每日允许摄入量（Acceptable Daily Intake，ADI）和配套的检测方法标准。统计显示，GB 2763-2021中涉及荔枝龙眼的农药MRLs有133项，涉及农药品种125个，其中推荐有配套的检测方法标准的限量有109项，在我国登记有效的限量有33项。对比GB 2763-2019，新增限量标准53项，增长率达到66.25%。此外，新增了方法标准3个。但是，基于荔枝龙眼的农药监测数据，荔枝龙眼上MRLs以及检测方法标准仍需继续补充，加快荔枝龙眼上的MRLs和检测方法标准的制定。荔枝龙眼上的MRLs和检测方法标准的制定仍需加快。

In order to understand the status of Chinese maximum residue limits (MRLs) standard for the pesticides in litchi and longan, and ensure the development of national litchi and longan industry, the current status of the Chinese MRLs standard for pesticides in litchi and longan were analyzed in this article based on the “National food safety standard-maximum residue limits for pesticides in food” (GB 2763-2021), combined with the registration of pesticides on the litchi and longan in China. The MRLs, Acceptable Daily Intake (ADI) and corresponding standards for detection methods are listed according to the types of pesticides. Statistics showed that there were 133 MRLs in 125 types of pesticides related to litchi and longan in GB 2763-2021, among which 109 recommended MRLs have corresponding detection methods, and 33 valid MRLs that have been registered in China. Comparing to GB 2763-2019, 53 MRLs standards were newly added and the growth rate was up to 66.25%. Moreover, 3 standards on detection methods were newly added. However, according to the data from the monitoring of pesticide residues, standards on MRLs and detaction methods for litchi and longan still need to be supplemented, and the process for setting up standards on the MRLs and detection methods for litchi and longan needs to be speeded up.
