AB  - Using different excellent tree species, carry out afforestation trials in different areas, the test site includes two places of horqin sand and kubqi desert, the survival rate of seedlings in the year of afforestation statistics, 2-3 years after afforestation statistics of late afforestation rate of preservation, and changes in the growth of afforestation seedlings, the investigation indexes include the tree height, diameter at breast height, the survival rate and the rate of preservation of afforestation seedlings.  2018 in Dalat Banner to complete the regional afforestation and sand control demonstration project of 130 acres, the selection of tree species are small poplar 2 and Changwu pine, small poplar and Changwu pine afforestation after the year's survival rate of more than 90%, 2 years after the preservation of seedlings are more than 85%, and the growth of good condition, no pests and diseases. The average height of small poplar 2 is 3.97m, average diameter at breast height (D.B.H.) is 4.96cm; Changwu pine is 1.03m, diameter at breast height (D.B.H.) is 3.62cm; the demonstration of afforestation and sand control was accomplished for 30mu in the saline and alkaline test base of Tongliao Kozuozhongqi Dongsu Forest Field; the selected species mainly include local native species: Phellodendron Bark, Ulmus domestica, Ulmus spiny elm, and Mapleus dendriticus; and the introduced species include Pterocarpus indicus, Pterocarpus mongoliculatus, Tamariskus sanguinis, Avenida avena, and small poplar 2. The survival rate of local native species of Phellodendron Bark, Prickly Elm, Ulmus domestica and Maple Genbao is more than 85%, and the preservation rate is more than 85% after 2 years; the survival rate of introduced species of Phellodendron Bark, Montserrat and Tamarix rubra is more than 90%, and the preservation rate is more than 85%, while that of Poplar No.2 is low due to the quality of the afforested seedlings. The three tree species have good growth, no pests and
