In winter, there are many pests in the soil of big cherry trees, such as peach borer and Zaobu. For this reason, before the earth is frozen, the soil under the tree should be turned over 25 to 35 cm deep so that the wintering pests in the soil can be frozen out or eaten by birds, and the pests on the surface can also be destroyed. Or the top soil pests pluck into the depths of the underground soil to suffocate them. Plowing the orchard will not only help improve the physical and chemical properties of the soil, but also help kill pests and diseases that overwinter in the soil.
An Oropharyngeal Airway is a medical device called an airway adjunct used to maintain or open a patient's airway. It does this by preventing the tongue from covering the epiglottis, which could prevent the person from breathing. When a person becomes unconscious, the muscles in their jaw relax and allow the tongue to obstruct the airway. An oropharyngeal airway has four parts: the flange, the body, the tip, and a channel to allow for passage of air and suction. Oropharyngeal airways come in a wide range of sizes.
