| 中文摘要: |
| 通过对玉林市荔枝主产区果园73份土壤样本养分含量分析,评价当地荔枝园土壤养分肥力现状。结果表明,当地荔枝园土壤养分有机质、碱解氮、速效钾、有效钙、有效镁、有效硼、有效钼含量偏低,有效磷和有效锌含量中偏低,有效铜含量中等,有效硫含量偏高,土壤pH值偏强酸性。栽培中要注意增施有机质肥、氮肥、钾肥、适施磷肥,重视钙镁肥的施用,及时补充硼肥；特别是含量属于缺乏水平的荔枝园,适量使用石灰,提高土壤酸碱度。本文旨在通过对玉林市荔枝园土壤养分含量分析及养分肥力现状评价,为当地荔枝栽培进行科学施肥提供指导。 |

| Through the analysis of Yulin City litchi orchards nutrient content of 73 soil samples, evaluation of local litchi orchard soil fertility status. The results show that, the local litchi orchard soil organic matter, alkaline N, available P, available K, available Ca, available Mg, available B, available Mo content were low, low P and Zn content, available Cu content medium, available S content was high, the soil pH value of strong acid. Cultivation to the attention of increasing application of organic fertilizer,N-fertilizer, K-fertilizer, suitable P, pay attention to Ca and Mg fertilizer, B- fertilizer timely supplement;especially the content belongs to lack the level of litchi orchard, proper use of lime, increase soil pH. This paper aims to evaluate the analysis of soil nutrient content in Litchi Orchard in Yulin city and fertility status, provide guidance for local litchi cultivation of scientific fertilization. |
