Spreng.) is a tropical and subtropical evergreen arbor, is a main tree species for producing agilawood, is a rare precious medicinal plant in the world, belongs to a domestic secondary protective plant, is also an internationally protected tree material, is 5-18 meters high, dark bark gray, smooth and tough, and has wrinkles, is thinned and fluffed when young, then gradually falls off, has no hair or nearly no hair, and is sometimes absent.
The increasing demand of the market of the Chinese eaglewood at home and abroad leads the price of the Chinese eaglewood to continuously rise, and reaches the ground of 'price in grams' and 'difficult demand for one Chinese eaglewood'. In view of the pretty market situation, the plantation of aquilaria sinensis artificial forest is in a very fruitful way in recent years, but most of the aquilaria sinensis artificial forest is young forest. In addition, the formation of the fragrant substances by the aquilaria sinensis is very slow, the formation of the fragrant substances generally needs about 6 to 8 years, and the fragrance yield (namely the ratio of the fragrant substances to the whole trunk or large-diameter branches) is very low. Therefore, how to rapidly promote the formation of aquilaria sinensis edgeworthia chrysantha (agilawood) in a short period of time becomes a key technology in the efficient cultivation of aquilaria sinensis artificial forests, and the release of the supply-demand market contradiction of agilawood becomes a key problem to be solved in the current production.
At present, a small amount of methods for rapidly promoting aquilaria sinensis to knot fragrance, such as mechanical trauma, chemical reagent smearing on a trunk and the like, are available in production, but the efficiency of promoting the aquilaria sinensis to knot fragrance is generally low in the past, the effect is limited to a small range of a trunk treatment part, the yield of the obtained agilawood is low, large-scale standardized and commercial production cannot be realized, and no report is found about a method for rapidly promoting the aquilaria sinensis to knot fragrance through the whole body.

The induction reagent is methyl jasmonate; in particular to methyl jasmonate water solution.
The condition that the leaves are heavily withered means that the leaves of the whole tree droop with little falling.
The method specifically comprises the following steps:
selecting young aquilaria sinensis trees formed by 3-6 years of raw heartwood in the transpiration exuberance period of the trees, drilling 3 holes with the diameter of 1.00cm and the horizontal depth of 1/2 at the trunk position with the height of 1.00m from the ground and at the angle of 90 degrees by using an electric drill obliquely downwards at 35 degrees, wherein the vertical height distance of 4 holes is 30.00cm, forming a four-hole spiral structure, injecting a methyl jasmonate aqueous solution with the concentration of 0.10-1.50% into the holes in a grading manner, injecting a total amount of 120.00m L into each tree, taking the condition that the leaves of the trees are severely withered as the standard, sealing the holes by using plasticine after injection, cutting and dissecting the trees after processing for 3-6 months, and obtaining agilawood as the russian odorum root, thereby achieving the purpose of the whole body and the fragrance of the aquilaria sinensis.
The method comprises the steps of taking part of reddish brown xylem, drying and crushing the xylem, accurately weighing 2.00g of heartwood sample by adopting a petroleum ether impregnation method, placing the heartwood sample into a sealed brown wide-mouthed bottle of 60.00m L, adding petroleum ether (analytically pure) with the boiling range of 60-90 ℃ of 30.00m L, placing the mixture into a constant-temperature shaking table to shake for 24 hours, repeating the treatment for 3 times, shaking and extracting for 24 hours, filtering supernatant, carrying out reduced pressure concentration in a rotary Concentrator (Concentrator5301, Eppendorf, Germany) until the petroleum ether is completely volatilized, obtaining heartwood essential oil, weighing and calculating the oil yield, measuring the components of the heartwood essential oil by adopting a gas chromatography-mass spectrometer (GC-MS) of American Agilent 6890N-5975I model, and calculating the relative content of each component of the essential oil by adopting an area normalization method.
The technical principle of the invention is as follows:
the tree is injected in 5-7 months with the largest transpiration amount, so that the inducer can diffuse in the largest range under the action of transpiration pulling force, and the range of inducing the formation of the incense is enlarged as much as possible. The four-hole spiral structure provided by the invention can increase the diffusion rate of the inducer and ensure that the inducer can be uniformly diffused to all parts of the xylem of the trunk as far as possible. The injection amount is generally enough to be injected until the leaves are seriously withered due to the difference of the sizes of the trees, and the trees can die due to the excessive amount. The selected inducer is methyl jasmonate aqueous solution, so that the methyl jasmonate released by the aqueous solution can be transmitted among xylem parenchyma cells of the trunk in a gaseous form, the induction range of the inducer is greatly expanded, and the whole tree body is formed.
