An infusion set comprises a liquid storage container (3) and an infusion tube (17). The liquid storage container (3) has a bottom outlet and is used for containing inducing liquid for agarwood. The infusion tube (17) is connected to the liquid storage container (3) and is used for delivering the inducing liquid for agarwood from the liquid storage container (3) to the trunk of the tree. The infusion set conveniently and precisely delivers the inducing liquid for agarwood to the trunk the top bough and the lateral branch of the tree so that the agarwood can be produced all over the tree. The infusion set can be applied to trees of Aquilaria sinensis with different ages and diameters at breast height to produce the agarwood hence overcoming the shortages of rot death and the like due to the large area bark and trunk injuries that are easily incurred by fast infusion and failure of precise quantitation and control and reducing the tree death rate.
