Resumo: |
This study, carried out in a six years stand of Eucalyptus x urograndis old located in Cachoeira Dourada - GO, in an area with soil predominantly Rhodic clayey with a crop-livestock-forest integration system that develops an important role in recovering degraded areas through a sustainable yield model. The objectives were to quantify the compartmentalized tree aboveground biomass; dendrometrically characterize the tree component of the system; Evaluate and test volumetric models for biomass of Eucalyptus urograndis trees. The spacing model adopted in the tree component of crop-livestock-forest integration system (IAFP) of this work, we chose to use three lines densely populated distancing three meters between them, and two meters between plants with fourteen meters between the rows, aiming to the integrated system for production of wood for energy (for six years) sawmill (fourteen) from eucalyptus. Above ground biomass was determined by fitting regression equations with collection of ten individuals classified and divided into dendrometric classes e and compartmentalized by cubed by Smalian method. It was related diameter at breast height (DBH) with height of each plant to determine the hypsometric relations Eucalyptus x urograndis and adjusting the values to seven models as independent variables were the diameter measured at 1.30 m tall (X1) in centimeters, and the total tree height (X2), in meters. To check the relationship between variables, there was simple linear regression with 95% statistical significance, noting the regression coefficient and the distribution of waste and to list the components of the biomass with the volume of each tree Eucalyptus x urograndis. It was also performed linear regression with 95% statistical significance for each of biomass component. Total productivity of eucalyptus biomass obtained from this integrated crop-livestock-forestry system was 144.35 Mg ha-1, resulting in a productivity 114.25 Mg ha-1 (79.14%) of wood. The estimated average height was 23.88 m, originated a total volume of 259.93 m3 h-1 and the average volume of 0.378 m³ per tree, a total gain of 0.063 m³ tree-1 y-1, yielding an annual increase of 43.32 m3 ha-1 yr- 1, thus complying with the farmer’s objectives in using wood component for energy production and sawmill. |
