1. An operation method of a soil conditioner spreader, the soil conditioner spreader comprising:
a spreader body, the spreader body is provided with a hopper in a middle part; the hopper is used for storing a solid conditioner; the spreader body is provided with a spreader rack in a front part; the spreader rack is provided with a mulching device on a front end; a ridger, a solid application device, two rotary tillage wheels and a liquid application device are successively arranged on the spreader rack from the rear to the front;
the solid application device comprises a feeding track, a solid tank and two spiral perforated drills; the two spiral perforated drills are respectively arranged on both sides of a bottom of the spreader rack and also in front of the ridger; the top of the spiral perforated drills extends upward into the solid tank from a bottom of the solid tank; the solid tank is provided with a top opening; both ends of the feeding track are respectively arranged in the hopper and the top opening of the solid tank;
the two rotary tillage wheels are respectively arranged on both sides of the bottom of the spreader rack and also in front of the two spiral perforated drills;
the liquid application device comprises a liquid tank, a connecting pipe and a nozzle; the nozzle is arranged at the bottom of the spreader rack and also between the spiral perforated drills and the mulching device; the liquid tank is located on the spreader rack above the nozzle; top and bottom ends of the connecting pipe are respectively connected with the liquid tank and the nozzle,, wherein, the method comprising:
leveling saline land;
advancing the spreader body and ridging by the ridger;
transporting the conditioner in the hopper to the solid tank through the feeding track;
discharging the conditioner from the solid tank to the spiral perforated drill;
performing, by the spiral perforated drill, deep plowing, rotary tillage and scarification, and applying the conditioner into the soil above a ridge;
performing rotary tillage on the ridge by the rotary tillage wheel;
transporting a culture solution of a fungicide or an herbicide/insecticide stored in the liquid tank to the nozzle, and spraying through the nozzle;
unfolding a head of a whole roll of mulch film hanging on the mulch film clamping groove;
laying the mulch film along a ridge surface;
flattening the mulch film horizontally by the mulch film pressing wheel against the ground;
scraping the soil against an edge of the mulch film to fix the mulch film; and
advancing the spreader body so that the mulch film is gradually lowered, covering the ridge surface.
