Abstract
A soil conditioner spreader and an operation method thereof are provided. The soil conditioner spreader includes a spreader body, a ridger, a solid tank, two spiral drills, a rotary tillage wheel and a mulching device, where the spreader body is provided with a hopper in a front part. The hopper stores a conditioner. The solid tank is arranged above the spiral drills. The spreader body is connected to the solid tank through a feeding track. The ridger, the spiral rills, the rotary tillage wheel and the mulching device are successively arranged at the bottom of the spreader body from the rear to the front. The ridger ridges first, and then the spiral drills perform deep plowing, rotary tillage and scarification and apply the conditioner to a ridge. The rotary tillage wheel performs rotary tillage, and a nozzle sprays a nutrient solution or an herbicide/insecticide. Finally, the mulching device mulches.
