A method of manufacturing laminated bamboo sliver lumber, comprising steps of: 1) preparing bamboo slivers, including: providing a bamboo, cutting off a segment of the bamboo so as to obtain a bamboo stem, cutting the bamboo stem along a radial direction thereof into bamboo tubes, splitting each bamboo tube along an axial direction thereof into bamboo strips each having a width of 8-25 mm, sectioning each bamboo strip into a bamboo inner skin sliver and a bamboo outer sliver including bamboo outer skin, and selecting and using the bamboo outer slivers and removing siliceous and wax layers on an outer surface of each bamboo outer sliver; 2) machining each dried bamboo sliver; 3) applying a glue to the bamboo slivers by glue coating or immerging process, in which a ratio of the glue to an absolute dry weight of the bamboo slivers is 3-16%; 4) arranging the glued bamboo slivers in which width directions of the bamboo slivers are consistent with a vertical direction, then pressing the arranged bamboo slivers and curing the glue under a side pressure of 3-15MPa and a top pressure of 1-6MPa so as to form the laminated bamboo sliver lumber; characterized in that the bamboo provided is more than 4 years of age and has an outer diameter of 17,78-38,1 cm (7-15 inch), the cut off segment of the bamboo has a length of 0.5m from a root of the bamboo, each bamboo tube has having a length of 0.3-2.6m, the bamboo outer sliver has an air dry density no less than 0.95 g/cm 3, siliceous and wax layers on an outer surface of each bamboo outer sliver are removed so as to obtain bamboo slivers each having a thickness of 1-4mm, the method comprises between steps 1) and 2) the steps of performing mothproofing, mildew proofing and antiseptic treatments to the bamboo slivers, then drying the bamboo slivers to a moisture content of 6-15%, each dried bamboo sliver is machined to a thickness of 0.5-3.5mm and a width of 5-22mm, then the machined bamboo slivers are dehumidified to a moisture content of 3-10%, the laminated bamboo sliver lumber is machined to have two inclined end surfaces, so that the inclined end surfaces of two adjacent laminated bamboo sliver lumbers can be spliced to form a spliced laminated bamboo sliver lumber having a desired length, and the glued bamboo slivers are arranged with their ends being staggered such that the laminated bamboo sliver lumber has two stepped ends, thereby two adjacent laminated bamboo sliver lumbers can spliced at their ends so as to form a spliced laminated bamboo sliver lumber having a desired length. 1) preparing bamboo slivers, including: providing a bamboo, cutting off a segment of the bamboo so as to obtain a bamboo stem, cutting the bamboo stem along a radial direction thereof into bamboo tubes, splitting each bamboo tube along an axial direction thereof into bamboo strips each having a width of 8-25 mm, sectioning each bamboo strip into a bamboo inner skin sliver and a bamboo outer sliver including bamboo outer skin, and selecting and using the bamboo outer slivers and removing siliceous and wax layers on an outer surface of each bamboo outer sliver; providing a bamboo, cutting off a segment of the bamboo so as to obtain a bamboo stem, cutting the bamboo stem along a radial direction thereof into bamboo tubes, splitting each bamboo tube along an axial direction thereof into bamboo strips each having a width of 8-25 mm, sectioning each bamboo strip into a bamboo inner skin sliver and a bamboo outer sliver including bamboo outer skin, and selecting and using the bamboo outer slivers and removing siliceous and wax layers on an outer surface of each bamboo outer sliver; 2) machining each dried bamboo sliver; 3) applying a glue to the bamboo slivers by glue coating or immerging process, in which a ratio of the glue to an absolute dry weight of the bamboo slivers is 3-16%; 4) arranging the glued bamboo slivers in which width directions of the bamboo slivers are consistent with a vertical direction, then pressing the arranged bamboo slivers and curing the glue under a side pressure of 3-15MPa and a top pressure of 1-6MPa so as to form the laminated bamboo sliver lumber;
