Abstract
[Objective] In order to understand the difference of growth and soil fertility of Eucalyptus spp plantations in different site conditions.[Method] Using 2 years old Eucalyptus spp plantations,the growth and soil physical and chemical properties in different slope position were compared.[Result] Eucalyptus spp plantations soil were generally acidic,surface concentrations were higher than deep,with the decrease of slope,trees growth and soil physical and chemical properties had been improved gradually,showing a positive trend,the surface soil fertility was better than deep soil in the same slope position.On the whole,the planting site soil fertility was at a low level,N and P were shortage seriously.[Conclusion] At the time of building Eucalyptus spp plantations in the future,we should choose the middle and lower place of the slope,for the upper part of the slope soil nutrient is lacking,should be increased fertilization after planting,and appropriate micronutrient properly to ensure normal growth of trees.关键词
