| 摘 要： | 镁是茶树必需的矿质营养元素，作为叶绿素的组分和辅助酶的活动，参与茶树的代谢，对促进茶树生长、提高茶叶产量、改善茶叶品质有着重要的作用．在茶园土壤中镁以矿物态、非交换态、交换态和水溶态存在，能够被茶树吸收的有效镁是交换态和水溶态镁．茶园土壤有效镁含量因为土壤母质、施肥、pH等不同而差别很大．湖南茶园土壤的有效镁含量平均值为0～15cm土层，38．4mg／kg；15～30cm土层，36．1mg／kg；30～45cm土层，32．0mg／kg．

| Abstract: | As component of chlorophyll and in coenzyme activation,Mg is an essential element for tea plant.It plays an important role in tea plant metabolism,enhancing the growth of tea plant,improving tea yield and quality.There are different states of Mg in the soil: mineral Mg,exchangeable Mg,non-exchangeable Mg and water-soluble Mg.Only water-soluble and exchangeable Mg can be absorbed by tea plant.Mg concentrations are variously relative to parent materials,fertilization level and pH value of tea plantation soil.... |
