摘要
为掌握临猗县果园土壤重金属含量情况,对临猗县24个点位的果园耕层土壤的重金属含量进行测定,依据绿色食品产地环境条件(NY/T391-2000)来分级和计算。结果表明:临猗县果园土壤重金属含量所选点的单因子评价达到国家绿色食品生产Ⅰ级指标;果园土壤铅、铬含量在0～15年内随树龄增加而增加。
To evaluate heavy metals content of orchard soil in Linyi Country,experiments were conducted to determine heavy metal contents of 24 points of the orchard plowed soil,to calculate and make classification by Environment Quality for Green Food Production and its Evaluation（NY/T391-2000）.The results showed that all points reached the standard of Class Ⅰ,which was accordance with green fruit production conditions.Contents of plumbum and chromium grow as age of trees increasing in range of 0 to 15 years.
