A straw indirect carbonization-based soil improvement method and system, the method comprising the following steps: (A) collecting straw, cutting the straw into straw particles; (B) extruding and destroying the surface of the straw particles; (C) using microwave heating to extrude the straw particles, obtaining puffed straw particles; (D) carbonizing the surface of the puffed straw particles, obtaining carbonized particles for discharge into soil. The indirect carbonization method of first breaking the wall and then puffing and carbonizing the surface can significantly reduce the energy consumed during carbonization and shorten the processing time of the straw, which is conducive to the straw carbonization and field application treatment of a large area of soil. At the same time, the surface-carbonized carbonized particles can provide sufficient biomass carbon for the soil, and it is not necessary to remove part of the carbonized particles from the field due to the excessive biomass carbon of the soil. In addition, the carbonized particles also well retain the nutrients in the straw.

This utility model relates to the field of feed processing technology and provides a feed extruder, including a cylinder with support plates fixed on both sides of the bottom end of the cylinder. A screw is installed inside the cylinder, a drive motor is installed on the outer wall of the cylinder at one end of the screw, and a discharge port plate is fixed on the outer wall of the cylinder at the other end of the screw. This utility model features a metering structure. When feed enters the feed hopper, it falls into the metering trough. At this time, a rotating rod rotates, driving the metering trough to rotate via a metering seat. Simultaneously, the rotating rod drives a stirring shaft to rotate via a transmission belt. Under the action of the equally spaced metering troughs, the feed is metered into the cylinder. The stirring shaft drives a stirring rod to stir the feed inside the feed hopper, effectively preventing feed bridging. This device facilitates the prevention of feed bridging, thereby improving the applicability of the feed extruder in use.
