不同土壤类型有效微量元素的空间特征——以张掖市临泽县为例
Study on the Contents of Available Trace Elements in Different Soils——A case study in Linze area,Zhangye city
摘要
Abstract
Mn,Zn,Fe,Cu,B in 0 20 cm soil were investigated In Linze County.We used the method of GIS and geostatistics to study the distribution characteristics of available trace elements in space in different types of soils,and make the spatial distribution map.Finally,according to the Gansu Provincial tillage layer soil nutrient grading standard,available trace elements of soil in Linze County were comprehensively evaluated.The results show that the saline soil,gray-brown desrt soils,aeolian sandy soil are lack of available trace elements,contents of available trace elements in peat swamp soil,irrigation and cultivation soil and meadow soil are relatively high;the overall available contents of trace elements in soil in Linze county are at the high level.In order to meet the demands of the local agricultural production,the application measures and dosages of micronutrient fertilizer should be improved to increase the contents of trace elements in soils.关键词
