Because of multiple factors, however, it has become endangered plant. For protecting and optimizing the population structure of this plant, it is important to explore the rejuvenation techniques. The stumping experiment was carried out on A. mongolicus in the western Ordos National Nature Reserve under different stumping heights, ground diameters, and treatments. The results show that the growth increment of new branches had apparent negative correlation with stumping heights, but had apparent positive correlation with stubble diameters. The appropriate stubble height for natural A. mongolicus was 3 cm. After the second growing season, the plant height was 44.5 cm, and the average quantity of new germinated branches was 37.4, 5.9 times of the control. After two years' growth, the length of new germinated branches reached 45.9 cm, an increase of 33.2 cm compared with that of the control, and the base diameter reached 9.98 mm. Treatment of different A. mongolicus brush had better effects than that of the same brush. The appropriate stubble diameter was 15.09-19.95 mm, and painting the stubble side helps to rejuvenate the plant., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=NNHvCnrIRUrjtlVBrFTOrg==, pdfFileSize=2610288, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
