In order to provide theoretical basis and scientific guidance for nutrient management and rational fertilizationof walnut orchard in Guizhou walnut main producingarea，126 soil samples of 0～ 40 cm from typical walnut orchards ofnorthwest and northern high latitude cold areas of Guizhou，southwestern and southern high latitude areas of Guizhou wereselected for nutrientanalysis.The results showed that 73.0% of soil pH was suitable for walnutgrowth，88.2% of soil organicmatter content was in the suitable range orabove.The total P and total N wereplentiful，while 22.2% of soil total K werein deficiency or extremedeficiency.7.9% of soil alkalide N content was in the middle or belowlevel.76.2% of availableP content in the suitable or aboverange.The content of available potassium was relativelydeficient，with 81.8% below themediumlevel.The exchangeable Ca and Mg contents were rich，with 0 and 8.7% below the mediumlevel，respectively.Available Mn and Cu wererich.Soil available B was in extreme deficiency，the proportion of below the middle level as highas99.2%.The ratio of available Fe and Zn in low and medium level was 45.2% and8.8%，respectively.The extent of soil nutrients deficiency showed as southwestern high latitude areas>northern high latitude cold areas>northwest high latitudecold areas>southern high latitude areas.The deficiency degrees of soil available nitrogen and available zinc in orchardswith fruits were more serious than those without fruits，but the content of available potassium was less than that of the no -fruitorchard.Ingeneral，the soil pH is suitable for walnut growth in the major producing areas ofGuizhou，the soil organicmatter and alkalide N content are above the mediumlevel，and the totalN，total P，exchange ofCa，Mg，available Mnand Cu arerich，while the soil availableK，available B and available Fe content arelow.And the soil totalK，available Pand available Zn in part of the walnut orchards are lower than thestandard.Aboveall，different walnut orchard fertilizationshould adjust measures according to local conditions，deep application of organic fertilizer and containing Fe，Zn，Bfertilizers as basefertilizer，and increasing the K of potash fertilizer arerecommended.At the sametime，the application ofacid fertilizer is recommended in the partial alkalineregion，and the proportion of phosphate fertilizer should be increased insomeareas.
