摘　　要：采集广东省荔枝主产区果园土壤样本63个,采用全国第二次土壤普查土壤养分分级标准来评价荔枝果园土壤养分肥力现状。结果表明,荔枝果园土壤有机质、碱解氮、有效钙含量均较低,速效钾为中下,有效磷、有效硫和有效铁含量较高,有效锰、有效锌含量为中上水平,有效镁和有效硼为低水平。整体上荔枝果园土壤养分肥力较低且不平衡。不同荔枝主产区土壤养分肥力状况差别很大,硼是荔枝园土壤最普遍缺乏的元素,钙、镁次之。针对广东荔枝园土壤养分肥力较低且不平衡的原因提出了相关防治对策。Soil samples （63） were collected in Guangdong Litchi plantations to evaluate the soil nutrient fertility status. The result showed that the contents of soil organic matter, available nitrogen and calcium were relatively low, available potassium mid-low , available phosphorus, sulphur and iron relatively high, available manganese and zinc mid-high, and available magnesium and boron low. Generally, soil nutrient fertility in Litchi plantation was lowe and disequilibrium. The nutrient fertility differences in different Litchi plantations were great. Boron was the most scarce element in Litchi plantation soil, calcium and magnesium took second place. The prevention and cure countermeasure were put forward according to low and disequilibrium soil nutrient fertility in Litchi plantations.
