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.

A trailed straw biomass granulator includes a first drive device and a forming device. The forming device includes a driving gear and a forming gear. The driving gear is evenly distributed with involute drive teeth along a circumference. A storage groove is formed between every two adjacent drive teeth. The driving gear includes an output hole in an axial direction, and an auger is arranged inside the output hole. A forming hole is defined between two adjacent drive teeth, and the forming hole penetrates into the output hole and the storage groove. The forming gear includes a base body, multiple involute sliding teeth and multiple reset springs, and the sliding teeth are evenly distributed on the peripheral side of the base body in a circumferential direction. The base body includes multiple sliding grooves in one-to-one correspondence with the sliding teeth, which are integrally formed with a slide block.
