| 中文摘要: |
| 为探究喀斯特地区野生枇杷的分布、生长状况、土壤特性，以贵州省27 株具有代表性的野生枇杷及
其立地土壤作为研究对象，调查记录植株生长状况，常规方法测定土壤养分含量。结果表明：贵州喀斯特地区野
生枇杷分布极为广泛，且分布地的土壤养分具有一定的共同特征，即速效钾、有机质、碱解氮、交换性钙、镁和有
效铜、锌、铁、锰含量比较丰富，而有效磷和有效硼的缺乏比较严重。尽管贵州喀斯特地区土层浅薄、有效磷和有
效硼的含量较低、交换性钙的含量普遍偏高，但是枇杷在此分布广泛且大多生长良好，推测枇杷对喀斯特高钙土
壤具有一定的适应性。 |

| In order to explore the distribution，growth status，and soil characteristics of loquat in Guizhou
karst areas，27 representative wild loquats and their soils were studied. The plant growth status and soil nutrient
contents were researched by conventional method. The results showed that the distribution of wild loquat was
very extensive and there were some common characteristics of soil nutrients in Guizhou karst areas. Available
potassium，organic matter，alkali-hydrolyzed nitrogen，exchangeable calcium，magnesium and available copper，
zinc，iron，manganese contents were relatively abundant. But the available phosphorus and boron were serious
deficient. Although the soil layer in Karst areas was thin，especially the content of available phosphorus was
low，the exchangeable calcium content was generally high，loquat grew well in this area，which indicated that
loquat had certain adaptability to the soil |
