摘要:

基于新疆民丰县85组农田表层土壤样品中的6种微量营养元素(Fe、B、Mn、Cu、Zn、Mo)的实测含量,运用地统计学方法对研究区土壤中微量营养元素的含量及空间分布进行分析。结果表明:Cu、Fe、Mn元素的块金系数在25%~75%,为中等程度的空间自相关性,空间变异同时受到自然因素和人为因素的影响;土壤B、Zn、Mo元素的块金系数小于25%,具有强烈程度的空间自相关性,空间变异受到影响的因素主要有成土母质、气候等自然条件。Fe、B、Zn元素的平均含量处于较缺乏水平,Mn、Cu元素的平均含量处于中等水平,Mo元素的平均含量处于较丰富水平。研究区土壤中6种微量元素之间存在一定程度的相关性。土壤有机质和pH对土壤微量营养元素含量均有不同程度的影响。

Abstract: In this study, the geostatistics method was used to analyze the content level of the essential micronutrient elements in farmland soil in Minfeng County, Xinjiang based on the test data of six micronutrients (Fe, B, Mn, Cu, Zn and Mo) in 85 farmland topsoil samples in the study area. The results showed that the nugget coefficients of Cu, Fe and Mn ranged from 25% to 75% with a spatial autocorrelation at moderate level, and the spatial variation was affected by both natural and artificial factors. The nugget coefficients of B, Zn and Mo in soil were lower than 25% with a high spatial autocorrelation, and the spatial variation was mainly affected by the natural conditions, such as the parent material and climate. The average contents of Fe, B and Zn were low, those of Mn and Cu were moderate, and the average content of Mo was high. There was a certain correlation among the six micronutrients in soil in the study area. The contents of soil micronutrients were affected by soil organic matter content and pH value to varying degrees.
