摘要
在荒漠草原进行的试验结果表明,由于稀土的应用,草场群落结构发生了一些变化,牧草产量和营养成份含量也不同程度地得到相应的提高和改善。因此,稀土是改良天然草场有效的技术措施之一。
The experiment was carried out at wulat eremo range,Bayannaor Amag(prefecture),NMAR. the results indicate that owing to the use of rare earth elements,the community structure changes,the hay yield increases,and the nutrient contents can be improved. The application of rare earth elements to the eremo rangelands significantly effect these variables. So,it is a proved method of range improvement.
