After the control is completed, the first lifting plate 7 is lifted to make the hollow thread drill 15 leave the soil.

[0049] The reduction motor 11 of the stem prevention module 5 is controlled to move the second lifting plate 8 to a suitable position so that the hollow microneedle 17 is inserted into the tree stem. The second water pump 28 is turned on to deliver the agent to the hollow microneedle 17 through the second connecting tube for injection prevention of the stem. At the same time, the annular electric heating compress ring is turned on to heat and promote the absorption and diffusion of the agent in the stem. After the prevention is completed, the second lifting plate 8 is lifted to allow the hollow microneedle 17 to leave the stem.

[0050] The folding rod 19 is controlled to unfold and adjust to a suitable angle by the twisting servo 23, so that the atomizing nozzle 21 is aimed at the leaves of the tree. The third water pump 20 is started to transport the agent to the atomizing nozzle 21 through the hose to spray the leaves of the tree for prevention and control. After the prevention and control is completed, the twisting servo 23 is controlled to fold and retract the folding rod 19.
