The invention relates to the field of nursery stock planting, and particularly relates to a method for cultivating large timber dalbergia odorifera. The method comprises the following steps: digging planting holes before dalbergia odorifera seedlings are planted, putting plant ash and weeds at the bottom of the planting holes, and planting; setting fixed cables above the dalbergia odorifera seedlings to fix trunks and guide growth of the seedlings; obliquely inserting a tripod into the ground on the side face of the dalbergia odorifera seedlings after the diameter at breast height of the dalbergia odorifera seedlings are more than 10cm, and the seedling height is more than 8m, adding a brick at the tube foot, and fixing the dalbergia odorifera trunks with the tripod. The method has the beneficial effects that mixture of plant ash and weeds is put at the bottom of the planting holes to avoid water shortage of seedlings in dry season; the fixed cables are matched with cable anchors and other supports to fix the trunks of dalbergia odorifera to achieve the effects of reinforcing and preventing dalbergia odorifera breakage caused by typhoon damage; and the effect of positioning and guiding growth of dalbergia odorifera.
