九阡李产地土壤环境质量及其鲜果中有机氯残留量和重金属含量的检测

Analysis and Evaluation on Soil Environmental Quality of Planting Jiuqian Plum and Organocholorine Pesticide Residue and Heavy Metals Content in Its Fresh Fruits

九阡李是地方早熟优良果树品种。为推广应用该品种,系统地检测了该品种产地的土壤环境质量,并对其产地环境质量现状作出科学评价,同时检测了九阡李鲜果中有机氯农药残留量和重金属Cu、Pb、Cd、Hg、As的含量。结果表明:三都县九阡镇白庙村、水条村、水夕村,周覃镇水备村土壤环境质量适合无公害水果九阡李种植基地的选择和建立;其鲜果无有机氯农药残留,5种重金属在鲜果中的含量亦在合理的低限范围内。研究结果为其产业化奠定了可行性支撑基础。

The soil environment quality of planting Jiuqian plum and organochlofine pesticide residue and Cu, Pb, Cd, Hg, As content in fresh fruits were analyzed and evaluated to popularize Jiuqian plum （a local fruit variety with early-maturing and good quality）. The results showed that the soil environment quality of Baimiao, Shuifiao, Shuixi and Shuibei villages, Sandu county, Guizhou accords with the planting condition for producing pollution-froe Jiuqian plum and its organochlorine pesticide residue and Cu, Pb, Cd, Hg, As content in fresh fruits were within the rational lower limits permitted by the standard.
