| 中文摘要: |
| 利用ICP-MS检测了从化青梅果园土壤矿质元素组成及其含量,按照无公害及绿色食品标准进行评价,并运用SPSS 19.0软件对其中的钾、钠、钙、镁、铁、铜、锌、硒、铅、铬10个元素进行主成分分析。结果表明：从化青梅果园土壤中重金属污染物处在清洁安全状态，适宜发展青梅绿色农产品生产，但土壤中营养元素氮、磷、钾以及镁、硼养分相对不足；主成分分析中，钾、钙、镁、铜、硒、铬是从化土壤中第一主成分，铁、铅是第二主成分，锌是第三主成分。 |
| 英文摘要: |
| The contents of mineral elements of greengage orchard soil in Conghua were detected by ICP-MS, and the soil environment quality of greengage orchard was assessed according to the soil environmental quality standard in the producing area of the nuisance free fruits orchard and the green food, and then SPSS 19.0 software was used to ten mineral elements (K, Na, Ca, Mg, Fe, Cu, Zn, Se, Pb, Cr) by principal component analysis. The results showed that Conghua was suitable for the development of green agricultural products of greengage because it had a clean and safe condition of heavy metal pollutants in orchard soil, but the nutrient elements (N, P, K) and Mg, B were deficient in soil; Conghua orchard soil had three principal components, the first principal component was Ka, Ca, Mg, Cu, Se, Cr, the second principal component was Fe and Pb, and Zn was the third principal component. |
