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, the potential of film mulching for vegetation restoration in such environments and plant growth and nutrients in artificial soil on slopes in high altitude areas were determined. Experiments were carried out in Jiuzhaigou County, Sichuan Province, to determine plant growth and nutrients in artificial soil on slopes under six different coverage rates (40%, 50%, 60%, 70%, 80% and 90%). Results showed that in each observation period, plant height, ground diameter and contents of EN, EP and EK in the soil of the film mulching treatment were significantly higher than those of the control, while the number of plant individuals per unit area was significantly lower than that of the control. When the coverage rate was 90%, plant height, ground diameter, biomass and nutrient contents in the soil were all higher than those under the other five treatments. Overall, our study suggested that applying film mulching technology when performing vegetation restoration on slopes in high altitude areas is promising, since it can promote plant growth and preserve soil fertility.

Designing of Wet Transformers as Artificial Soil for Flower Tree Cultivation

This research is focusing on designing of wet garbage transformers as artificial soil. According to the result, it represented that the artificial soil can be brought to cultivate Marigold trees to be abundant with giving for Grade B flowers. Moreover, it has the duration to bloom in short times with good quality of tree’s height and suitable size of flower’s diameter.
