Abstract: In order to study the effect of soil-fixing polymer materials on the growth of herbaceous plants in the reclaimed soil of the mining area, three common plants, such as Sadawang, ryegrass and amorpha, were selected to be planted in the natural soil of the mining area, and indoor planting experiments were carried out. The effects of spraying the soil-fixing polymer materials xanthan gum (XG) and polyacrylamide (PAM) on the fitness of three plants were studied, and the plants sprayed with water were used as controls to observe the germination rate of the plants within the period of observation, and the average plant average. Height, root growth status, etc. were used as judgment indicators. The experimental results showed that both types of polymer materials had a promoting effect on the growth of the three plants. Among the three plants, the ryegrass plant had the best growth effect. It germinated first after 3 days of sowing, and its germination rate could reach over 90% after being treated with the three solutions. After the observation period, the germination rate and plant height of the three plants sprayed with xanthan gum and polyacrylamide increased compared with the control group sprayed with water. Taking ryegrass as an example, the germination rates are 91% (water), 97% (PAM), and 94% (XG), respectively. After spraying polyacrylamide and xanthan gum solution, the pH value of the soil changes between 7.0 and 7.6, in the neutral and neutral alkalescence range, and the overall acid-base environment is suitable for plant growth. Among them, the amorpha and Sadawang plants slightly increased the soil pH value, while ryegrass showed the opposite effect. Spraying polyacrylamide and Xanthan gum solution, planting plants can significantly reduce the soil conductivity. The combined application of ryegrass and polyacrylamide further improves the effect of soil salinization. This experiment provides good validation for the combined use of polymer materials and plant ecological restoration.
