Embodiment 1

[0015] The 7-year-old Baimuxiang tree has a diameter at breast height of 54.81mm at 1.2m, and the first branch is selected. The height of the branch is 121mm, and the diameter is 19.13mm. Apply lanolin containing 5% gibberellin (0.25g gibberellic acid crystalline powder, dissolved in 1ml white wine with 56% alcohol content, fully mixed with 4.75g lanolin) on the branches in a circle, with a width of 13mm. Then use a semi-steel German clamp to clamp it at the coating position, rotate the screw of the clamp 270°, and wrap it with plastic wrap for protection. After 180 days of artificial stress induction, all clamps were removed, and every mm on the cross-section was detected 2 Fatty area.

[0016] Control group 1: a 7-year-old whitewood tree, with a diameter at breast height of 36.45mm at 1.2m, choose the branch of the first branch, the height of the branch is 133mm, and the diameter is 13.73mm. Clamp the semi-steel German-style clamps on the branches, rotate the clamp screw 2...

Embodiment 2

[0022] For the 7-year-old Baimuxiang tree, the diameter at breast height at 1.2m is 56.91mm, and the branch of the first branch is selected. The height of the branch is 161mm, and the diameter is 16.76mm. Apply lanolin containing 3% gibberellin (0.15g gibberellic acid crystalline powder, dissolved in 1ml white wine with 56% alcohol content, fully mixed with 4.85g lanolin) on the branch with a width of 13mm. Then use a semi-steel German clamp to clamp at the coating position, and wrap it with plastic wrap for protection. After 180 days of artificial stress induction, all clamps are removed, and every mm on the cross section 2 The fat-containing area is 0.3721mm 2 .

Embodiment 3~4

[0024] The 7-year-old Baimuxiang tree has a diameter at breast height of 48.26mm at 1.2m, and the first branch is selected. The height of the branch is 156mm and the diameter is 11.72mm. Apply lanolin containing 3% gibberellin (0.15g gibberellic acid crystalline powder, dissolved in 1ml white wine with a degree of 56%, and fully mixed with 4.85g lanolin) on the branch with a width of 15mm. Then use a semi-steel German clamp to clamp it at the coating position, set different rotation angles of the clamp screw, and wrap it with plastic wrap for protection. After 180 days of artificial stress induction, remove all clamps, and detect every mm on the cross-section of the clamps 2 The lipid-containing area, the results are shown in Table 2. On the premise of not destroying the cambium and xylem, increasing the compressive stress by increasing the rotation angle of the clamp screw can improve the efficiency of aroma formation.

Abstract

The invention provides a novel method of artificially inducing an aquilaria sinensis (lour.) gilg tree to produce agarwood. According to the method, an agarwood producing promotor containing plant hormones is coated onto the aquilaria sinensis (lour.) gilg tree; a clamp hoop is clamped on the coating position; the clamp hoop is rotated and is tightly fixed through a screw rod; covering is performed by a preservative film; and compression stress is continuously applied for artificial induction of agarwood production. The method has the advantages that the cambium and the xylem of the aquilariasinensis (lour.) gilg tree are not damaged; the operation is simple; the cost is low; the compression stress applied by the clamp hoop and the agarwood producing promotor are used at the same time toachieve the cooperative effect; the agarwood production promotion effect is good; and the method is suitable for large-scale application.

Description

technical field [0001] The invention relates to the technical field of agarwood genus Agarwood, in particular to a novel method for artificially inducing the aroma of agarwood trees. Background technique [0002] Agarwood is a well-known traditional medicinal material in my country. Agarwood has certain pharmacological effects, including antibacterial activity, anti-inflammatory activity, anti-tumor activity, and antioxidant activity. Domestic agarwood is the resin-containing wood of Aquilaria. Baimuxiang is also known as daughter incense (Guangdong), Guanxiang (Guangdong), Liumashu (Hainan), Yaxiangshu, etc. It is mainly produced in Hainan, Guangdong, Guangxi and other places. It is a second-level key wild protected plant in my country. [0003] In nature, agarwood will only be produced when the agarwood plant is stimulated or damaged. Due to the high value of agarwood and the large market demand, it has been plundered and over-cut for a long time. Obviously, natural agar...
