| 摘要: |
| 分析不同树龄组的库尔勒香梨叶片矿质营养,采用诊断施肥综合法（DRIS）对叶片进行营养诊断，筛选营养诊断的DRIS参项，提出DRIS标准。结果表明：不同树龄组库尔勒香梨低产果园的养分平衡总体水平都较低，但DRIS诊断需肥顺序各不相同。8～10年树龄的低产果园对营养元素Zn、Mg、Fe的需求强度较大，12～15年树龄的低产果园对营养元素Mg、N、Fe的需求强度较大，16～20年树龄的低产果园对营养元素P、N、Ca的需求强度较大，22～25年树龄的低产果园对营养元素K、Mn、Cu的需求强度较大。 |

| Abstract: |
| Through the analysis of minerals in Korla fragrant pear leaves with different ages, nutrition diagnosis of leaves was performed using Diagnosis and Recommendation Integrated System (DRIS) method, in order to obtain DRIS parameters and set standard for nutrition diagnosis. The results showed that the overall level of nutrient balance is low for all leaves of different ages for low yield orchards. However, the orders of nutrient requirement are not identical for different kinds of leaves. The 8～10 year old leaf needs more minerals of Zn, Mg, and Fe, the 12～15 year Mg, N, and Fe greatly, the 16～20 year P, N, and Ca greatly, and the 22～25 year K, Mn and Cu. |
