Veneer gluability and the gluing technology for 6 poplar varieties were studied by means of orthogonal experimental design with assembly pattern,resin consumption,adhesive formulation,and hot pressing technology as influencing factors.It was found that it was difficult to develop a set of universal gluing technology for all of the poplars tested because of the remarkable variation in wood properties among them.However,higher bonding strength could be obtained with pressing pressure of 0.5 to 0.8 MPa,pressing time of 40 s/mm,UF resin consumption of 280 to 340 g/m 2,additive ratio of 15 between wheat flour and resin,and assembly pattern of constant thickness in most cases.The Populus deltoides barter.CV.‘Lux’(Ⅰ 69/55) and P.×euramericana Guineir CV,‘San Martino’(Ⅰ 72/58)were easy to glue.The P.bolleana L.within the sect. Populus had the lowest pH value and buffering capacity,and therefore could be well glued without any special consideration.The P.cathayana Rehd.,P.simonii Carr.,and P.gansuensis C.Wang et H.L.Ying within sect. Tacamahaca had higher pH value and buffering capacity,and therefore the glue shear strength was not able to reach the Chinese National Standard’s requirement unless appropriate conditions were adopted.
