Abstract

A handheld soil fixed-point disinfection device for a crop growth period is provided. The device includes a top-opened barrel, the barrel being internally divided into a liquid storage chamber and an assembly chamber; a plurality of support rods fixed at a bottom of the barrel; a target ring fixed at bottoms of the plurality of support rods and configured to contact a ground fixed point; a needle provided between the plurality of support rods and capable of being inserted into soil through the target ring to inject a fumigant liquid; and a force accumulation mechanism provided on the barrel and configured to eject the needle. The device not only is more labor-saving and simpler in use by ejecting the piercing needle, but also can be adapted for different people and used more comfortably through the handle with an adjustable angle and an adjustable length.
