| Abstract: | Afforestation experiment was carried out on nutrition bag seedlings of H Calligonum leucocladum, Caragana korshinskii and ZygophyUum xanthoxylon afforested in different site condition and different density, and survival rate, height of tree, ground diameter and crown diameter were determined. The results showed that survival rate of Haloxylon ammodendron was highest; growth of psammophytes showed enrichment planting forests〉afforest on thick overlying beach; growth increment of nutrition bag seedlings increment of nutrition bag seedlings sand〉afforest on dune〉 afforest on of psammophytes showed Calligonum leucocladum〉 Haloxylon ammodendron〉 Zygophyllum xanthoxylon〉 Caragana korshinskii in the same site conditions and management level. |
