摘要
镁是植物生长的必需元素,作物缺镁将影响植物体内叶绿素的合成和多种酶的活化,从而严重影响植株正常生长,而土壤中镁的有效性以及元素间交互作用也是影响植物对镁进行吸收的重要因素。通过总结国内外研究成果,对土壤镁的含量、形态、植物对镁吸收以及镁的有效性作一个简要概述。
Magnesium is one of the most indispensable element for plant growth. Lacked of Mg will affect the composing of cholrophyllous and the activation of some kinds of enzyme, consequently affect the natural growth of plants. However, the validity of Mg in soil and the interaction of elements are the important factors for Mg absorbing in plants. By summing up the reseach all over the world, this paper simply summarize the content, form, absorbing and validity of Mg in soil.
