摘　　要：近年来,玉溪市菜用大豆生产发展迅速,部分田块重迎茬现象严重,菜用大豆病虫害逐年加重,施用化学药剂量增多,鲜荚粒安全及环境污染风险加剧,制约玉溪市菜用大豆产业可持续发展。为提高菜用大豆安全性,文章以不同浓度条件下三唑酮和高效氯氟氰菊酯对菜用大豆进行根外浇施和叶面喷施,研究其对菜用大豆鲜荚粒农残含量的影响。结果表明:(1)随着采收期延长,根外浇施和叶面喷施三唑酮及高效氯氟氰菊酯后,菜用大豆鲜荚粒农残含量均呈下降趋势;(2)随着三唑酮及高效氯氟氰菊酯施用浓度降低,根外浇施和叶面喷施处理后,菜用大豆鲜荚粒农残含量均呈下降趋势;(3)不同浓度三唑酮叶面喷施处理后,不同采收期菜用大豆鲜荚粒农残含量均小于最大残留限量值;(4)根外浇施三唑酮1∶1000倍液21 d后,适宜采收菜用大豆鲜荚粒;(5)根外浇施和叶面喷施不同浓度高效氯氟氰菊酯后,不同处理菜用大豆鲜荚粒农残含量均小于最大残留限量值;(6)根外浇施三唑酮和高效氯氟氰菊酯处理较叶面喷施处理菜用大豆鲜荚粒农残含量高,根外浇施三唑酮处理的菜用大豆鲜荚粒农残含量为最大残留限量值的1.9倍。In recent years,the production of new edamame in Yuxi City had developed rapidly,and the phenomenon of continuous cropping in some fields had resulted in an increasing trend of new edamame diseases and insect pests year by year.The dosage of chemical drugs applied had increased significantly,which increased the safety of fresh pod and environmental pollution risk,and seriously restricted the sustainable development of new edamame industry in Yuxi City.In order to improve the safety of new edamame,the effects of root pouring and leaf spraying of triazolone and beta-cyhalothrin on the residue content of fresh pods of new edamame were studied.The results showed that:(1)With the extension of harvesting period,the residue content of fresh pods of new edamame decreased after root pouring and leaf spraying with triazolone and beta-cyhalothrin;(2)With the decrease of the application concentration of triazolone and beta-cyhalothrin,the residue content of fresh pods of new edamame decreased after root pouring and foliar spraying;(3)After leaf spraying with different concentrations of triazolone,the residue content of fresh pods of new edamame in different harvesting periods was less than the maximum residue limit;(4)After twenty-one days of pouring triazolone 1∶1000 times solution,it was suitable for harvesting new edamame pods for vegetable use;(5)After root pouring and leaf spraying with different concentrations of beta-cyhalothrin,the residue content of fresh pods of new edamame under different treatments was less than the maximum residue limit;(6)The residue content of fresh pods of new edamame treated with external pouring of triazolone and beta-cyhalothrin was higher than that treated with leaf spraying.The residue content of fresh pods of new edamame treated with external pouring of triazolone was 1.9 times of the maximum residue limit value.
