By arranging the clamping head capable of automatically measuring the diameter of the tree, it is guaranteed that when the clamping head clamps the tree, the corresponding amount of liquid medicine is automatically matched according to the position of the clamping head, then the corresponding amount of liquid medicine is injected into the tree, automatic measurement is completed, the liquid medicine is quantified, and the work efficiency is improved. Errors and procedures of manual control quantity are reduced, and steps of trunk injection prevention are simplified.

The invention discloses a trunk injection control device for forestry trunk borers, and belongs to the technical field of forest protection. Comprising a drilling machine, a drill rod, a collecting unit and an injection unit. The core improvement is that an elastic telescopic unit is arranged on the mounting sleeve of the drill rod and comprises an elastic arc-shaped plate with a second liquid outlet hole. The device has two working states: in a drilling state, an elastic arc-shaped plate shrinks inwards to form a drilling slag discharging channel, and is matched with a negative pressure system of a collecting unit to realize synchronization of drilling and slag discharging, so that a drill bit is effectively prevented from being stuck; and residual drilling slag in the second liquid outlet hole is actively cleaned, it is ensured that a channel is unblocked, and then accurate liquid injection is conducted. The problems that in the prior art, drilling slag is prone to blocking a liquid outlet hole, the drilling efficiency and depth are affected by unsmooth chip removal, and the chemical injection dosage is inaccurate are solved, and integrated operation of efficient drilling, thorough slag removal and accurate chemical injection is achieved.

Our invention is about the modification of the trunk injection syringe for the precise application of oxytetracycline for Huanglongbing (HLB) or the Citrus Greening Disease and different rates of curry leaf extract through trunk injection. The purpose of the adapter is to connect the syringe pump to flexible silicone tubing, which then connects to the threaded needle injector. The purpose of using the flexible silicone tubing is to provide the user with the possibility to hang the spring-loaded syringe from nearby branches since the mechanical contact between the threaded needle and the trunk is not strong enough to directly support the weight of the syringe filled with medicine. qPCR was performed at the end of the experiment to validate bactericide efficacy, and an increase in Ct value. Curry leaves extract-based bactericide formulation can emerge as an effective and sustainable method for citrus greening disease management, bolstering the global citrus industry.
