The invention relates to the technical field of dalbergia odorifera core material growth, in particular to an artificial positioning growth control method for a Hainan dalbergia odorifera core material. The artificial positioning growth control method comprises the following steps: 1, selecting plants growing for twenty years, and from April to May, longitudinally cutting the parts, where no corematerial is generated, of branches with the diameter of 10 cm or more by using a sharp tool; 2, stirring deep-layer yellow mud prepared in advance into paste by taking edible acetic acid and clear water as a solution, applying the deep-layer yellow mud to plant cuts, and wrapping and fixing the cuts by using adhesive tapes; 3, after five days, removing the adhesive tapes, and spraying a potassiumpermanganate water solution, thereafter, spraying the potassium permanganate water solution once every ten days for four consecutive times. The artificial positioning growth control method for the Hainan dalbergia odorifera core material is simple, easy to operate and capable of shortening production time; the quantity of the core material is increased, the quality of the core material is also improved, and the great economic value is obtained.
