This invention discloses a polymer granulating agent for ecological restoration in high-altitude and cold regions and a preparation method thereof, relating to the field of ecological restoration; the granulating agent is composed of the following components in mass ratio: 50-80 parts of polymer, 10-30 parts of plant fiber, 5-15 parts of microbial agent, 0.5-2 parts of water-retaining agent, 0.5-2 parts of stabilizer, and 1-5 parts of auxiliary agent. The method includes uniformly mixing the polymer, plant fiber, microbial agent, water-retaining agent, stabilizer, and auxiliary agent in proportion, and then adding the mixed materials into a twin-screw extruder for melt extrusion to obtain molten material. This invention has good soil improvement effects, can improve the water retention performance of the soil, improve soil structure, and promote plant growth. Furthermore, the process is simple and easy to implement, and the specific process parameters in the preparation process are beneficial to ensuring the stability of product quality.
