The Technology of Afforestation by Conservation-base in the Rocky Mountain Area of Beijing

To overcome the low survival rate and slow growth in the rocky mountain areas of Beijing,an afforestation technology by conservation-base was used to improve the local environment of plant growth in the Experimental Forest Farm of Beijing Forestry University.The conservation-base that was made by mixing soil,peat,perlite and fertilizer in the volume ratio of 5∶3∶1∶1 to investigate the impact on the survival rate and growth.Results showed that,the survival rate,seedling height and growth rate in basal diameter increased significantly with the base.Platycladus orientalis and Pinus tabulaeformis had the highest survival rate,Acer truncatum followed,and Quercus variabilis blume the lowest.
