Plant growth lighting device with adjustable diffused light proportion

The invention provides a plant growth lighting device with an adjustable diffuse light proportion. The plant growth lighting device comprises a main rod, a nest base, a sliding block, a lighting blade and diffuse reflection surrounding cloth. The nest base is assembled at the bottom of the main rod, the multiple lighting blades are distributed on the periphery of the nest base in a radial shape and hinged to the nest base, the sliding block is assembled on the main rod in a lifting sliding mode, and the sliding block is connected with each lighting blade through a connecting piece; the diffuse reflection surrounding cloth surrounds the peripheries of the multiple lighting blades. The multiple lighting blades are driven to swing by controlling the sliding block to ascend and descend on the main rod, then the orientation of the lighting blades is adjusted, and the proportion of diffused light is adjustable. Therefore, illumination with different requirements can be met. 本发明提供一种漫射光占比可调的植物生长照明装置，包括主杆、巢座、滑块、照明叶片和漫
