山西省蔬菜地有害生物药防现状及残留控制对策研究

采用速测法对山西省2003年至2004年10个地级市不同时期的生产蔬菜和市场销售蔬菜共22 846个样品进行了农药残留阳性率的测定调查,研究分析表明,山西省蔬菜上的农药残留阳性率呈下降趋势,说明各级政府和植保部门对蔬菜农药残留超标问题的重视及采取的治理措施已取得了初步成效。但在蔬菜生产高峰季节和蔬菜病虫危害高峰期生产的蔬菜农药残留阳性率仍然较高,表明了实施蔬菜病虫无害化生态控制的任务任道重远,施用化学农药防治病虫的科学水平仍需进一步提高。为此作者提出进一步降低山西省蔬菜农药残留的6项对策。

Current Status for Controlling Pests by Agrochemicals and Monitoring Pesticide Residues in Vegetables Collected in Shanxi Province

During period of 2003-2004,as many as 22 846 samples of vegetables taken from fields and markets,representing 10 cities of Shanxi Province,were analyzed by a quick-detection method in our lab.The results showed that positive samples for the pesticide residues in vegetables were in dropping tendency,suggesting some success of efforts for local governments and plant protection departments.However,in some cases,the number of positive samples exceeding MRL in vegetables was still high,especially,when outbreak of pests,indicating that controlling pesticide residues in vegetables is a very hard work and we have a long way to go.In addition,we have proposed 6 countermeasures to lower levels of pesticide residues in vegetables in Shanxi Province.
