摘　　要：为了解黑龙江省农业科学院克山分院不同茬口试验地有效铜的含量和分布状况,春耕前在其40块试验田的耕层土壤（0-20 cm）采集土样,采用0.1 mol·L^-1稀盐酸浸提处理土样,原子吸收法直接进样测定。结果表明：有效铜含量平均为0.36 mg·kg^-1,其中80%取样点有效铜含量达到中等水平,少数缺铜,局部严重缺铜。In order to know the content and distribution of available Cu of different previous crops in the field of Keshan Branch of Heilongjiang Academy of Agricultural Sciences,the soil samples were collected from top soil（0-20 cm） of 40 experimental plots in the spring season,0.1 mol·L-1 hydrochloric acid was used to treat soil samples,atomic absorption spectrometry was used to detect available Cu content.The results showed that：the average content of available Cu in the experimental plots was 0.36 mg·kg-1,the available Cu content of eighty percent soil samples reached middle level,a small number of plot soil was deficiency copper and copper in partial plot soil was deficient severely.
