Nutrient characteristics of soils for loquat （Eriobotrya japonica）in Guizhou

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
