Artificial soil for shrub slope protection in karst area and method for preparing same

Abstract

The invention discloses an artificial soil for shrub slope protection in the karst area and a method for preparing the same. The artificial soil is made of following materials by weight: 20-50 portions of wood fibers, 5-12 portions of organic fertilizers, 300-600 portions of nutrient soil, 0.02-0.03 portions of seeds, 450-650 portions of water, 0.1-0.5 portions of water retention agent, 0.2-0.5 portions of adhesive, 24-33.5 portions of phosphorus slags and 0.2-0.5 portions of bactericide. The invention takes the on-the-spot collected nutrient soil as principal materials. The wood fiber can free soil. The organic fertilizer provides fertility for the seed germinating and growing. The artificial soil is viscous which can be adhered and stacked on the plant-growing elements after spraying inthe karst shrub slope protection area provided with the plant-growing elements by a sprayer for bringing a base for the seed growth, effectively resisting the rainwash and aeolation, preventing the water and soil loss.

Description

A kind of artificial soil for shrub slope protection in karst area and its preparation method technical field The invention relates to an artificial soil and a preparation method thereof, in particular to an artificial soil used for slope protection of shrubs in a karst area and a preparation method thereof. Background technique Karst landform refers to various landforms formed by the dissolution of soluble rocks by water and the accompanying mechanical action. Karst landforms are widely distributed in Guangxi, Guizhou, Yunnan and other places in China. In recent years, with large-scale engineering construction and mining, a large number of exposed slopes have been formed in karst landforms, resulting in a large number of rock and soil slopes that cannot be restored to vegetation. It is almost impossible to restore vegetation coverage naturally on the surface in a short period of time; The existing slope engineering reinforcement measures mostly pursue strength and efficie...

Problems solved by technology

The advantages of the rock slope ecological protection plant growth matrix are: wide source of raw materials, simple processing and manufacturing technology, low cost, and can meet the growth structure required for plant growth on hard rock slopes in arid and semi-arid areas, and at the same time provide The water and nutrients necessary for growth, but this plant growth substrate is not suitable for slopes with large slopes during use, and it is not suitable for areas with a lot of rain and heavy impacts in karst areas; at the same time, the existing The use of plant growth substrates in karst slope shrub areas still has the problem that it is not easy to adsorb on karst landform slopes, and the plant germination rate and root growth rate are low.
