| 中文摘要: |
| 对广西南丰蜜桔园土壤样品、叶片样品和果实样品进行检测分析。结果表明，所研究的南丰蜜桔园土壤pH普遍偏酸；土壤有机质、有效磷、有效锌、交换性钙含量较高；碱解氮和有效钾含量中等；交换性镁、有效硼含量较低；柑桔叶片氮含量大部分低于适量范围，而磷、钾含量大部分处于适量范围，少量处于高量水平；柑桔园土壤pH值与土壤交换性钙和交换性镁分别呈显著和极显著正相关性，土壤有机质与碱解氮呈显著正相关；土壤有效锌和有效钾含量与果实可溶性固形物含量呈极显著正相关，交换性钙含量与可溶性固形物呈显著正相关，而pH值和有机质与可溶性固形物呈显著负相关；叶片中钾素与果实Vc呈显著正相关。该研究结果将为广西南丰蜜桔的科学施肥提供参考。 |
| 英文摘要: |
| To analyze and detect soil、leaf and fruit samples in Guangxi Nanfeng mandarin orchards. The results showed that soil pH is acidic; organic matter, effective phosphorus, zinc and exchangeable calcium in soil are at high level. Nitrogen and potassium content is at moderate level; exchangeable magnesium and boron content are at low level; most nitrogen content in citrus leaf are below the right amount of range. However, most phosphorus and potassium content are at the appropriate amount of range, Only a small amounts of them are at a high level; soil pH are positive with soil exchangeable Ca and significantly positive with exchangeable Mg. The correlation between soil organic matter and nitrogen was significantly positive; Moreover, both soil available Zn and potassium content are significantly positive with soluble solids in fruits. Additionally, exchangeable calcium content and soluble solids showed a positive correlation. While pH and organic matter are negatively associated with soluble solids; K in leaves are positive with Vc in fruits. These results will provide scientific reference for fertilization in Guangxi Nanfeng mandarin. |
