Description
Technical field
The present invention relates to a kind of prescription of soil base material of revegetation, it belongs to ecological environmental protection engineering and hydro project technical field.
Background technology
China's expressway construction meets the mountain to level off hilltops in building the process of highway in recent years, forms many exposed massif rock faces, manyly causes the massif of " riddled with gaping wounds " because of opening a mine, quarrying, and also all need afforest the restore vegetation view.Therefore press for a kind of China's geotechnical slope, particularly greening technique of rock slope reality of meeting, adopt the quick ecological reparation of artificial method realization to this class side slope vegetation, the present invention claims revegetation.That China Patent No. 02120423.3 discloses is a kind of " exposed rock mass plant again green planting matrix and multiple method for green ", this planting matrix is the % meter by weight, is made up of 60-80% loam, 10-25% clay, 3-6% cement or 2-6% glue paste, 0.2-0.5% composite fertilizer, 0.1-1.5% cake fertilizer, 0.5-2.5% water-holding agent, 3-10% water and 1-5% organics additive.It is not enough, and point is: organic content is low in the planting matrix component, thereby hardens, the ventilation poor water retention property; Composite fertilizer, cake fertilizer quantity is few and the back heterodyne.
