Description

Technical Field

[0001] The utility model relates to the technical field of tobacco planting, and more specifically to a tobacco root and stem disease pesticide application device. Background Art

[0002] Tobacco rhizome disease is a common and important disease that affects the quality of tobacco leaf production. Improper prevention and control will result in reduced tobacco leaf yield or even total crop failure in tobacco fields. Therefore, during tobacco planting, it is necessary to apply pesticides to the rhizome of tobacco to prevent the occurrence of tobacco rhizome diseases. Existing tobacco rhizome disease application devices usually use sprayers to apply pesticides to the bottom stems of tobacco plants, generally applying pesticides from the stems 30 cm above the ground, and then the liquid medicine flows along the stems to the roots and infiltrates below the ground, thereby achieving the application of pesticides to the roots of tobacco. However, there are problems such as insufficient depth of the liquid medicine application, uneven application of the liquid medicine to the roots, and waste of the liquid medicine, which affects the effect of the application.

[0003] Therefore, how to provide a tobacco root and stem disease pesticide application device that can improve the pesticide application effect is one of the technical problems that urgently need to be solved in this field. Utility Model Content
