水-土壤-牧草之间矿物质转化耦合系统研究概况

Reviews of mineral transformation coupling system between water,soil and forage

牧草对矿物质的吸收和转化主要与水和土壤中可吸收矿物质有关。矿物质的缺乏或过量会引起土壤有机质含量和酸碱度变化、水源成分差异以及牧草生长发育受阻和饲用品质下降,而土壤和水源的改变直接影响牧草对矿物质的利用。本文综述了常量矿物元素和微量矿物元素在水-土壤-牧草间发生转化耦合及其含量变化对牧草产量及品质的影响,旨在为优质牧草的生产提供理论依据。

The absorption and transformation of minerals by forage is mainly related to the absorbable minerals in water and soil.The lack or excess of minerals can cause changes in soil organic matter content and p H,differences in water source composition,and hindered growth and development of forage and reduced feed quality,while changes in soil and water sources directly affect the use of minerals by forage.This article reviewed the transformation and coupling of major mineral elements and trace mineral elements between water-soil-forage and the influence of their content changes on forage yield and quality,aimed to provide a theoretical basis for the production of high-quality forage.
