湖北省耕地土壤中、微量元素含量状况分析
An analysis of the content of soil medium and trace elements in cultivated soil of Hubei province
摘要
Abstract
To investigate the spatiotemporal evolution patterns and driving factors of medium and trace elements in cultivated land soils in Hubei province,monitoring points were established throughout the province from 2012 to 2021.A total of 68 representative soil samples were collected,encompassing two utilization methods and three typical soil types.The contents of 10 medium and trace elements,including Ca,Mg,S,Si,Fe,Mn,Cu,Zn,B,and Mo,were determined.Based on the grading standards of the Second National Soil Survey,the characteristics of the changes in medium and trace elements in cultivated land soils in Hubei province over the decade were analysed.The results indicated that from 2012 to 2021,the average contents of Ca,Mg,Si,Fe,Mn,Cu,B,and Mo in Hubei province soils showed an increasing trend,with Ca and B increasing by more than 100%;while the average contents of S,Cu,and Zn showed a decreasing trend.In terms of regional distribution,the Jianghan plain and the southeastern Hubei province hilly areas had the highest Ca content(>8500 mg·kg-1),while the northwestern Hubei province mountainous area had the highest contents of Mg(980 mg·kg-1),Mn(47.9 mg·kg-1),and Mo(1.62 mg·kg-1).Regarding land use types,the Fe(174.5 mg·kg-1)and Cu(4.66 mg·kg-1)contents in paddy soils were significantly higher than those in dryland,while the Ca,Mg,Si,and Zn contents were higher in dryland soils.In terms of soil types,the deficiency of Zn(1.39 mg·kg-1)in paddy soil and B(0.17 mg·kg-1)in yellow-brown soil were prominent,while the Ca content in fluvo-aquic soil(12736 mg·kg-1)was abundant,which was twice as high as that in paddy soil.The study suggested that the dynamics of medium and trace element abundance and deficiency in cultivated land in Hubei province were jointly influenced by multiple factors.It was recommended to implement differentiated and precise application schemes for medium and trace element fertilizers based on the characteristics of soil nutrient abundance and deficiency,as well as crop characteristics.关键词
