武功山草甸土壤有效态微量元素与有机质和pH的关系

微量元素是植物生长的限制性营养因子,以江西省武功山山地草甸土壤为研究对象,对土壤的有效态微量元素与有机质和p H的关系研究。结果表明,有机质对有效态微量元素具有吸附作用,有效态微量元素对p H变化敏感。土壤有效态微量元素Fe、Mn、Zn的含量,随有机质的增加而显著（P〈0.05）增加。随着土壤p H的增大,土壤有效态微量元素Fe的含量显著（P〈0.05）降低,土壤有效态微量元素Mn、Zn的含量显著（P〈0.05）增加。研究揭示了武功山山地草甸土壤有效态微量元素与有机质和p H的相关性,同时也为武功山山地草甸植被保护及修复等提供了理论依据。...

Bibliography:Microelement is one of the essential elements for plant growth. The experiment took place at the Wugong mountain meadow of Jiangxi province, and the relationships between its available soil microelement with organic matter and pH were studied. The result showed that the organic matter had adsorption to the available microelement, and available microelement was sensitive to pH. The contents of the available soil microelement Fe, Mn, Zn were significantly （P 〈 0.05 ） increased with the increase of organic matter. With the increase of soil pH, the content of available soil micreelement Fe was significantly （P 〈 0.05 ） decreased, and the contents of available soil micreelement Mn, Zn were significantly （ P 〈 0.05） increased. This research revealed the relationship between available soil microelement with organic matter and pH in Wugnng mountain meadow and provided a theoretical basis to Wugnng mountain meadow vegetation protection and restoration.
