| 中文摘要: |
| 为了解海南中西部荔枝园土壤养分状况,为该区的荔枝园水肥管理施肥提供科学依据袁以海南岛中西部荔枝园为研究对象,分析其土壤pH值及养分含量,依据海南省第2次土壤普查的土壤养分含量分级标准对土壤养分进行等级划分。结果表明：海南中西部果园土壤多为酸性，且土壤有机质、全氮、碱解氮、有效磷和有效钾的含量普遍偏低，交换性钙、镁的含量较高；土壤中、微量元素含量较为丰富，其中铁、锰、锌的含量等级均达一级标准。荔枝园所处地形和管理方式是其土壤养分含量分布差异的主要原因。 |
| 英文摘要: |
| In order to understand the Litchi orchard soil nutrient status, collecting 29 representative soil samples in Central and West Hainan Litchi plantations to evaluate the soil nutrient fertility status. Compare with the 29 soil samples of The Second Soil Survey of Hainan province. The results indicated that the contents of soil organic matter, total nitrogen, available nitrogen, available phosphorus, and available potassium were relatively low, but available calcium and availability magnesium were very high. The contents of micro-elements such as available iron, available manganese and available zinc were relatively high. The distribution of soil contents was mainly determined by the orchard landform and management system. |
