Description

Technical Field

[0001] The invention relates to the technical field of leech breeding, in particular to a pesticide application device used in a leech breeding pond. Background Art

[0002] Leeches, also known as leeches, are blood-sucking annelids. It is very common to encounter leeches in the wild, but leeches can easily cause infection after biting people and sucking blood, so we should learn to protect ourselves. When attacked, we should deal with it calmly. Leeches are divided into three types: dry leeches, water leeches (leeches), and parasitic leeches. The first two are often encountered. The "nests" of dry leeches are mostly in the weeds by the stream, especially in piles of rotten dead wood and leaves and moist hidden places. They usually lurk in fallen leaves, grass or under stones, waiting for an opportunity to suck the blood of humans and animals, while water leeches lurk in the water grass. Once someone goes into the water, they will swim out quickly and attach themselves to the bodies of humans and animals, and leave after a full meal. In actual operation, we found that the method of applying pesticides in leech breeding ponds is generally through manual spraying.
