| 摘 要： | 试验采用含硒、锌、铜、锰等元素的微肥对牧草进行叶面施肥，研究通过这种施肥途径对牧草品质的影响。同时采用此种牧草饲喂奶牛，研究这种牧草对奶牛血液中相应元素含量及奶牛生产水平的影响。结果表明，牧草中硒、锌、铜、锰的含量有显著的提高；奶牛采食这种牧草90d后，血液中硒、锌、铜的含量显著提高，生活水平有所增长。

| Abstract: | The experiment used the fertilizer containing trace elements selenium(Se),zinc(Zn),copper(Cu) and manganese(Mn) was sprayed on growing grass in order to study the quality of the grass.And using the grass sprayed trace element to feed dairy cattles.Studying the varieties of trace elements in the cattle blood and the effects on productivities of the dairy cattle.The results showed:The contents of Cu,Se,Zn,Mn in the grass sprayed trace elements and in the blood of the dairy cattle's were fed the grass increased significantly. The productivity of the dairy cattle fed the grass improved. |
