Abstract: Twenty grass forage and soil samples were collected from different regions and four different pastures of Aba.Results indicated that Ca,Na and Zn contents of forage grasses had no significant differences between different regions.The content of P,Fe,Cu,K,Mg,Mn and Se in the forage grasses between different regions was significantly different(P<0.05).The average content of P,Zn and Se is insufficient for ruminant animal nutrient requirement.The content of Ca in the soil of different regions had no significant difference.Total phosphorus and soluble phosphorus contents of soil were significantly different between different regions(P<0.05).Relevant analysis indicated that P and Ca contents of forage grasses had no correlation with its soil contents.

Key words: Aba county, Forage, Soil, Mineral element

摘要: 采用常规方法测定了四川阿坝县4个不同牧场秋季(9月)牧草矿物元素含量及土壤中的钙磷含量,以期为该地区反刍动物的放牧饲养提供依据。结果表明:阿坝县4个地区秋季牧草矿物元素中钙、钠和锌的含量差异不显著,磷、铁、铜、钾、镁、锰和硒含量差异显著(P<0.05),其中磷、锌和硒的含量不能满足反刍家畜的营养需求,需要补饲;土壤中钙含量差异不显著,全磷和有效磷差异显著(P<0.05);牧草中的钙、磷含量与土壤中钙、磷含量之间没有显著的相关性。
