湖北省耕地土壤中、微量元素含量状况分析OA
An analysis of the content of soil medium and trace elements in cultivated soil of Hubei province
为探明湖北省耕地土壤中、微量元素养分含量现状及其驱动因素,于 2012-2021 年在全省设立监测点,采集具有代表性的土壤样品 68 个,涵盖 2 种土地利用方式及 3 类典型土壤类型,测定Ca、Mg、S、Si、Fe、Mn、Cu、Zn、B 和Mo 共 10 种中、微量元素含量.基于第二次全国土壤普查及湖北省近期相关研究的分级标准,分析湖北省耕地土壤中、微量元素 10 年间变化特征.结果表明,2012-2021 年间,湖北省土壤中Ca、Mg、Si、Fe、Mn、Cu、B 和Mo 的平均含量呈上升趋势,其中Ca 和B 增幅超过 100%;而S、Cu 和Zn的平均含量呈现下降趋势.区域分布上,江汉平原区和鄂东南丘陵区的Ca 含量最高(>8500 mg·kg-1),鄂西北山地区Mg(980 mg·kg-1)、Mn(47.9 mg·kg-1)和Mo(1.62 mg·kg-1)含量居全省首位.土地利用方式中,水田Fe(174.5 mg·kg-1)、Cu(4.66 mg·kg-1)含量显著高于旱地,而旱地土壤中Ca、Mg、Si 和Zn 含量较高.土壤类型方面,水稻土缺Zn(1.39 mg·kg-1)、黄棕壤缺B(0.17 mg·kg-1)问题突出,潮土Ca(12736 mg·kg-1)含量丰富,高于水稻土 2 倍.研究表明,湖北省耕地中、微量元素丰缺动态受多因子共同作用,建议依据土壤养分丰缺特征与作物特性,实施差异化中、微量元素肥料的精准配施方案.
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.
