Even planted eucalyptus plantation biomass and productivity of the preliminary study


Generation increases did not show a downward trend. Plantati** with planting soil degradation , reduced productivity , has been dem**trated for most species ,MBT scarpe 果实着色的理论与实践_638070, although the trial by three generati** with trees planted ,Ralph Lauren shop, maintained high productivity ,Ralph Lauren shop, and management of eucalyptus cultivation practices , forest genetics and tree improvement and management on short rotati** . Forest alive , kill litter layer biomass and productivity are increased with the algebra decreasing from generation to generation , and third-generation stand between understory vegetation biomass were significantly different, with the planting density and rotation period shorter correlation this will affect the plantation system from fat function and maintenance of soil fertility . Suggesti** as to retain the original vegetation ,Ralph Lauren shop, or between the species in the forest floor and other nitrogen-fixing plants to increase production of understory ground cover and increased forest Guangxi Forestry Science 12 Volume 34 places from fat function . Different end of the giant eucalyptus tree algebra 3.6 layer productivity 12.26 ~ 18.50t / (hm · a) between the origin of eucalyptus trees and other productivity compared to [ 3,12 ] , showing a relatively high productivity . East Gate eucalyptus forest plantation planted even though by many generati** , still maintain a high level of productivity ,Ralph Lauren shop, which is East Gate forest seedlings in the seed business in the use of reasonable density , scientific fertilization and intensive management measures inseparable. Visible , seeds and seedlings scientific silvicultural measures is to reduce the productivity of forest planted with an effective measure .
