The invention discloses an efficient and environmentally-friendly Dalbergia odorifera induction liquid. The efficient and environmentally-friendly Dalbergia odorifera induction liquid comprises a liquid body A, and the liquid body A is prepared from the following raw materials: a Dalbergia odorifera heartwood extract, sea water and enzymes, wherein the mass ratio of the Dalbergia odorifera heartwood extract to the seawater to the enzymes is (1-2):(1-2):(1-3). The induction liquid has the advantages that the induction yield is remarkably increased, the induction efficiency is high, a trunk is promoted to grow thicker, an outstanding effect for promoting the trunk to form Dalbergia odorifera heartwood is achieved, and the trunk and roots of the Dalbergia odorifera can form the high-quality heartwood; an in addition, seawater resources are fully utilized, a lot of chemical reagents are not used, and the induction liquid is more environmentally friendly.
