| 中文摘要: |
| 通过对深圳市南山荔枝园养分资源及其利用状况的调查分析，为南山荔枝生产中肥料的合理使用提供参考。结果表明，南山荔枝供试果园土壤中水解氮、速效钾含量偏低，有效磷、有效锌含量丰富，有效镁和有效硼处于缺乏水平。供试果园氮、磷、钾素全年使用量较大，三大元素比例中磷素偏高，而钾素偏低；各果园间投肥结构及施肥量差异明显，部分果园存在过量施肥状况。 |
| 英文摘要: |
| Soil nutrients and its utilization of Nanshan litchi orchard in Shenzhen were investigated in order to offer the suitable reference data for fair use of fertilizer during Nanshan litchi planting. The results show that available nitrogen and potassium contents in the soil were low while phosphorus and zinc contents were high. In addition, the soil was deficient in magnesium and boron. The annual usage amount of nitrogen, phosphorus and potassium was high. Phosphorus content was the highest and potassium content was lowest. There was significant difference in fertilization system and amount among the orchards. Excessive fertilization exists in some orchards. |
