以温宿县春季萌发受抑早实核桃园作为研究区，通过采集不同土层土壤进行粒度和盐分分析。研究结果表明：温宿县春季萌发受抑早实核桃园与对照土壤均主要由细沙和粉粒组成，总体属于壤土或沙土质地；土壤以粗组分为主，分选性很差；萌发受抑核桃园土壤总盐含量显著高于对照(P <0.01)，不同土层之间含盐量存在较大差异，土壤盐分含量与机械组成有很强的相关性，与沙粒含量呈显著负相关，而与土壤粉粒和黏粒含量呈正相关，与粉粒含量的相关性达到极显著水平(P <0.01)。
以溫宿縣春季萌髮受抑早實覈桃園作為研究區，通過採集不同土層土壤進行粒度和鹽分分析。研究結果錶明：溫宿縣春季萌髮受抑早實覈桃園與對照土壤均主要由細沙和粉粒組成，總體屬于壤土或沙土質地；土壤以粗組分為主，分選性很差；萌髮受抑覈桃園土壤總鹽含量顯著高于對照(P <0.01)，不同土層之間含鹽量存在較大差異，土壤鹽分含量與機械組成有很彊的相關性，與沙粒含量呈顯著負相關，而與土壤粉粒和黏粒含量呈正相關，與粉粒含量的相關性達到極顯著水平(P <0.01)。

Taking inhibited walnut in early-bearing walnut orchard in spring in Wensu County as research area,differ-ent soil granularity and soil salt were analyzed through collecting the different soil layer.Result shows that:the soil in the walnut orchard and the control soil in Wensu County in spring are composed of fine sand and silt,overall be-longing to loam or sandy soil.Soil is mainly by coarse combination ,sorting features of soil is poor;the total salt content of the soil in the walnut orchard are significantly higher than the control (P <0.01);salt content among dif-ferent soil layers have large differences,soil salt content and mechanical composition has a strong correlation,is sig-nificantly negatively correlated with sand content,positively correlates with soil silt & clay content,and reaches a significant level (P <0.01)with the correlation of silt content.
