Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting, in particular to a pesticide injection pile. Background Art

[0002] Traditional pesticide spraying requires farmers or agricultural workers to manually spray pesticides row by row, either handheld or on their backs. This method is prone to duplicate spraying and omissions, making it extremely inefficient, especially on large farmlands. Furthermore, manual fatigue limits farmers' working time. Traditional pesticide spraying methods often make it difficult to precisely control the dosage and timing of pesticides. This leads to pesticide waste, increasing agricultural production costs and potentially causing unnecessary pollution to soil and water sources. Manual pesticide spraying requires extensive physical labor and long working hours. This not only increases farmers' workload but also limits their time for other farmland management tasks, thereby reducing overall agricultural production efficiency. Utility Model Content
