摘　　要：本研究搜集了来自不同地区的120份大麦饲料样品,采取单因素方差分析的方法对饲料大麦矿物质元素进行对比分析。结果表明:黄熟期的饲料大麦中钙、磷、钾、镁、铁、锌、硒、铜、锰平均含量分别为62.25%、373.75%、46.75%、154.75%、6.18%、4.29%、9.43%、0.62%、1.22%;总体来看,受光照、温度、土壤、地理位置、播种期等的影响,不同地区、不同时期的大麦青贮饲料中矿物质含量差异较大,差异系数较好地反映了大麦青贮饲料中矿物质元素的变化程度。This study collected 120 samples of barley silage from different regions.The mineral elements of barley silage were analyzed by one-way ANOVA.The results showed that the average contents of CA,P,K,Mg,Fe,Zn,Se,Cu,and Mn in barley silage were 62.25%,373.75%,46.75%,154.75%,6.18%,4.29%,9.43%,0.62%,and 1.22%,respectively.Overall,the mineral content of barley silage exhibited significant variations in different areas and periods due to the influence of light,temperature,soil conditions,geographical location,and sowing time.The coefficient of difference effectively reflected the extent of changes in mineral elements in barley silage.
