摘要

The method involves providing a number of bore holes in a region of crown eaves of to-be treated trees. A mycor tree injectable medium is introduced into the bore holes by compressed air in a diluted manner. Dilution is formed such that 1.5 kilogram of the mycor tree injectable medium is dissolved in 800 to 1600 liter of water. The diluted medium is introduced in an amount of approximately 1.5 liters per bore hole. The mycor tree injectable medium is introduced into a soil with a turbojet air lance of spindler MTM type and RW 45 type.
