| Abstract: | Agriophyllum squarrosum,Artemisia sphaerocephala and Artemisia ordosica are the dominant plant species at different stages of vegetation succession in the southern Tengger Desert.A field-pot experiment was conducted at Wuwei Station for Desert Control Research in summer 2009.Response of the seedling emergence rates of the 3 species to two soil types(sand and sandy loam) and seven sand burial depths(0,1,2,3,4,6 cm and 8 cm) was measured.Seedling emergence rate of A.squarrosum seeds buried at 0 cm in sand was... |
