早实核桃园土壤粒度特征及其与盐分的相关性分析

Correlation Analysis of Soil Granularity Characteristics with Salinity in Early Bearing Walnut Orchard

以温宿县早实核桃园作为研究区,采集不同土层土壤进行粒度和盐分分析。结果表明,温宿县早实核桃园土壤主要由细砂和粉粒组成,总体属于壤土或砂土质地。土壤以粗组分为主,分选性很差。早实核桃园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。与砂粒含量呈显著负相关,而与土壤粉粒和粘粒含量呈正相关,与粉粒含量的相关性达到极显著水平(P<0.01)。

The early bearing walnut orchard in Wensu county was taken as a study case, and the soft granularity and salinity by collecting soil samples of different layers were analyzed. The results showed that the soil of the early bearing walnut orchard in Wensu was composed of silt and sliver sand, which belonged to loam or sand. The soil was based on coarse fractions with poor sorting. There were significantly different among the soll salinity contents of different layers in the early bearing walnut orchard, and their soil salinity content correlated significantly with soil mechanical composition. There was a strong negative correlation between soil salinity content and sliver sand, but soil salinity con- tent had a significant positive correlation with silt and clay, and a extremely significant correlation with silt by correlation analysis（ P 〈0.01）.
