Problems solved by technology

This protection method can maximize the recovery of slope vegetation and has good environmental benefits. However, when the initial vegetation is restored, the high germination rate and fast-growing herbaceous plants are in an advantage in the competition for resources such as water, fertilizer, and light, and inhibit the growth of woody plants. For the growth and development of plants (trees, shrubs), it is difficult to realize the design concept of slope protection plant communities with woody plants as the main and herbaceous plants as the supplement
In addition, there are problems such as poor vegetation protection at the seedling stage and poor stability of vegetation growth layers in high and steep rocky slopes, which seriously affect the quality and effect of slope vegetation restoration projects.

Abstract

The invention relates to an environmental-protection type vegetation nutritional basal disc prepared by mixing and press molding of the following components in parts by weight: 100 parts of soil, 10-16 parts of cement, 1.5-5.5 parts of a slow-release fertilizer, 0.5-1 part of a water retention agent, 1.6-3.5 parts of an acid-base balance regulator, 3-5 parts of a plant fiber, and 5-23 parts of garden waste. The nutritional basal disc can build a good plant growth environment, and is low in cost, stable in structure and wide in adaptability. The invention also provides an application of the nutritional basal disc in rock slope vegetation restoration, and the problems of rock slope protection and rapid greening are better solved.

Description

technical field [0001] The invention relates to the technical field of ecological protection, in particular to an environment-friendly nutrient substrate suitable for rock slope vegetation restoration and its application. Background technique [0002] With the rapid development of my country's social and economic construction, infrastructure construction such as roads, railways, hydropower, and mines is also developing rapidly, and there are more and more exposed slopes caused by blasting construction and filling and excavation. The exposed slope loses the original vegetation cover, and the stability of the slope surface decreases, which easily leads to the occurrence of disasters such as soil erosion, landslides, and debris flows. The vegetation restoration of slopes, especially the vegetation restoration of rocky slopes is the main difficulty of ecological construction. Although foreign soil spraying, thick matrix spraying and other technologies introduced from abroad hav...
