摘要
通过对黑惠灌区猕猴桃生产基地土壤样品的采集、监测,依据国家《土壤环境质量标准》GB15618-1995二级标准作为评价标准,重点分析评价了对人体危害较大的重金属元素镉(Cd)、砷(As)、铬(Cr)、铅(Pb)等项目。分析评价结果表明:黑惠灌区猕猴桃生产基地土壤基本无重金属污染,适宜于猕猴桃的种植。HS07 a、b,HS08 a、b两处土壤样品镉(Cd)超标属轻度污染,主要是人为长期不合理使用化肥农药所致。
The soil samples were collected and monitored in Yangtao production base of the Heihui irrigated area. The pollution status of soil heavy metals, which conclude Cd, As, Cr, and Pb, were evaluated emphatically according to the Standard of the Soil Environment Quality ( GB15618 - 1995 11 ). The results indicated that Yangtao production base of the Heihui irrigated area were not polluted significantly by the heavy metals on the whole. The Cd exceeded the standard in the two samples of HS07a. b, HS08a. b,due to the irrational use of chemical fertilizer and agricultural chemicals for a long period.
