| 中文摘要: |
| 以湖南省湘西自治州60个椪柑(Citrus reticulata Blanco)果园为对象，分析湘西椪柑产区土壤矿质营养情况，土壤pH值及树龄与果园营养状况及果实品质的关系。结果表明，湘西椪柑产区70%以上果园土壤酸化，土壤中多数矿质养分含量适量或过量，而碱解氮、有效硼交换性钙和交换性镁含量缺乏；叶片中氮、钾、钙、镁和锌含量缺乏，磷、锰含量适量，铁、铜含量过量。随土壤pH值升高，土壤交换性钙、交换性镁和有效铜含量升高，而有效铁和有效锰含量降低；叶片氮、铁含量在酸性和弱酸性（4.5 |
| 英文摘要: |
| With 60 ponkan (Citrus reticulata Blanco) orchards located in Xiangxi autonomous prefecture, Hunan province, the soil nutrients, tree nutrients and fruit quality based on different soil pH value and tree age were investigated. According to the results, soil acidification was found in more than 70% of the investigated orchards. Most of the element nutrients were optimum or excess in the soil, but alkaline hydrolytic N, available B, exchangeable Ca and exchangeable Mg were deficient. In the leaves, except P and Mn contents optimum, contents of N, K, Ca, Mg and Zn were deficient, but Fe and Cu showed excess content. With the rise of soil pH value, exchangeable Ca, exchangeable Mg and available Cu contents increased in the soil, but available Fe and available Mn decreased. N and Fe contents in leaves from soil 4.5 |
