Effects of Film Mulching on Plant Growth and Nutrients in Artificial Soil: A Case Study on High Altitude Slopes

Vegetation restoration on slopes is generally difficult, especially in high altitude areas since the environment has dramatically changing weather conditions that are not suitable for plant growth. In this study, potential of film mulching vegetation such environments and growth nutrients artificial soil were determined. Experiments carried out Jiuzhaigou County, Sichuan Province, to determine under six different coverage rates (40%, 50%, 60%, 70%, 80% 90%). Results showed each observation period, height, ground diameter contents EN, EP EK treatment significantly higher than those control, while number individuals per unit area was lower control. When rate 90%, diameter, biomass nutrient all other five treatments. Overall, our study suggested applying technology when performing promising, it can promote preserve fertility.
