摘要

巴西林业的主要物种是桉树,这种物种适应我们的土壤和气候条件,我们也有杂交和无性系,非常适合不同的木材用途,造林处理是众所周知的。采用育苗基质(NS)和生物炭(BC)在20%、40%、60%、80%和100%的混合浓度下对桉树的育苗效果进行了评价。克隆VM01和I144。测定了茎粗、株高、片数、根、芽鲜重、干重和迪克森指数。与硝态氮相比,BC对幼苗生长没有促进作用,但应考虑低于10%的比例

Fast pyrolysis biochar in eucalyptus seedling production
The main species of Brazilian forestry is Eucalyptus, this specie is adapted to our soil and climatic conditions, also we have hybrids and clones ideally suited for different timber uses and the silvicultural treatments are well know. The experiment was set up with nursery substrate (NS) and mixtures of NS with biochar (BC) at 20, 40, 60, 80 and 100% to evaluate the seedling production of Eucaliptussp. clones VM01 and I144. Stem diameter, height, number of sheets, fresh and dry weight of roots and shoots and Dickson index were evaluated.The BC did not improve seedling growth compared to NS, but ratios below to 10% should be considered for this purpose
