Description

Technical Field

[0001] This utility model relates to the field of root irrigation device technology, and in particular to a root irrigation device for the prevention and control of diseases and pests in Buxus macrocarpa. Background Technology

[0002] Buxus macrocarpa is a common plant in urban greening and landscape construction. It has strong adaptability and ornamental value. However, during its growth process, it is very susceptible to various pests and diseases such as aphids, inchworms, and powdery mildew, which seriously affect the healthy growth of the plant and the landscape effect.

[0003] Traditional pest and disease control often relies on foliar spraying of pesticides. This method not only has low pesticide utilization rates, resulting in large amounts of pesticides being dispersed into the air, causing environmental pollution and pesticide waste, but it also fails to effectively kill pests and diseases lurking in the soil. Furthermore, traditional methods are ineffective against pests and diseases that penetrate deep into the roots, leading to recurring outbreaks. To address the shortcomings of existing technologies, we propose a root irrigation device for the control of pests and diseases in Buxus macrocarpa. Utility Model Content
