The invention provides a production technology for a bamboo-wood composite building template. The production technology for the bamboo-wood composite building template comprises the following steps that step 1, bamboo curtains, eucalyptus planks and poplar wood pieces are dried in a drying room; step 2, the dried eucalyptus planks are sawn into rectangular wood pieces, the wood pieces are closely attached, no overlapping and gap exist, and the wood pieces are pieced together to form the eucalyptus planks through bonding threads; step 3, glue coating treatment is conducted on the pieced eucalyptus planks; step 4, the composite sequence is a poplar wood face layer, the eucalyptus plank, the bamboo curtain, the eucalyptus plank, the bamboo curtain, the eucalyptus plank and the poplar wood face layer, and the fiber directions of the eucalyptus planks are perpendicular to the fiber directions of the poplar wood face layers; step 5, the composite template is sent into a hydraulic machine to press; step 6, film coated paper impregnated with resin glue is laid on the pressed poplar wood face, and compression molding is conducted through a thermocompressor; step 7, after hot compression, edging and edge sealing of the periphery are conducted on the template. The production technology for the bamboo-wood composite building template adopts moso bamboo as a main material, the resources are rich, the price is cheap, and the production cost is low; the surface of the building template is flat and smooth, resin consumption is small, and the anti-bending and compressive strength are high.
