Institute of Hechi Integrated Study, Hechi 547000, China; 2. Forestry College of Guangxi University, Nanning 530004, China） To better understand the growth of Eucalyptus on the land of different grades of rocky desertification in karst region,and explore the method for the revegetation in karst rocky desertification land,two grades（S1：moderate desertification,S2：severe desertification）of rocky desertification land in Northwest Guangxi were selected for planting Eucalyptus. On the desertification land,the planting bank was built by brick,new soil from other site was filled in the bank before planting tree. The survival rate and growth of Eucalyptus were investigated in the 4th year of forestation. The results showed that,The survival rates of Eucalyptus in land S1 and S2 were 29.5% and 21.5%,respectively,the former was 1.37 times of the latte |
