常量矿物质元素含量是影响牧草质量的重要因素之一,本文对内蒙古阿拉善额济纳荒漠区60种牧草进行了这方面的分析研究。得出的结果是,钙含量最高的是灰毛假紫简草(8.73%),最低的是拂子茅(0.031%);磷含量最高的是蓍状亚菊(0.258%),最低的是短叶假木贼(0.096%);镁含量最高的是沙拐枣(1.67%),最低的是麻黄和灌木铁线莲,均为0.11%;硫含量最高的是花花柴(3.28%),最低的是木紫菀(0.012%)。60种牧草中,含6种以上的科有禾本科、豆科、菊科、藜科和蒺藜科,其中每个科的钙、镁、硫、磷总量均值,蒺藜科居首位(3.86%),禾本科最低(0.75%).
The content of constant mineral elements is one of the important factors that affect the quality of forage. In this paper, 60 species of forage grass in Ejina Ejina Desert of Inner Mongolia were studied in this aspect. As a result, the highest content of calcium was Fagus vulgaris (8.73%), the lowest was Cephalotaxus (0.031%); the highest content of P was Acremonium (0.258%), the lowest was (0.96%) were the shortest leaves (0.96%); the highest content of magnesium was A. fulva (1.67%), the lowest was Ephedra and shrub Clematis, both 0.11% The lowest is aster (0.012%). Among the 60 species of pasture, there are more than 6 families including Gramineae, Leguminosae, Compositae, Chenopodiaceae and Chenopodiaceae, with the total amount of calcium, magnesium, sulfur and phosphorus in each branch being the highest, and Chenopodiaceae the highest (3.86 %), Grass lowest (0.75%).
