Problems solved by technology

However, these materials have certain defects, such as: chemical glue seriously pollutes the desert and groundwater environment; nylon materials cannot be degraded, and it is easy to cause secondary pollution to the environment, etc.
In addition, the most serious thing is that none of the existing methods can be laid in pieces. For the parts that cannot be laid, there is still the effect of not being able to completely fix sand and prevent soil erosion.

Abstract

The invention discloses a fast-growing grass mat, which comprises straw powder, clay, bentonite, seeds, sodium humate, a binder and a polypropylene fiber net; a preparation method of the fast-growing grass mat includes the following steps: The following steps: step 1, ammoniation treatment of straw powder; ammoniation treatment method is one of cellar ammoniation method, plastic bag ammoniation method and furnace ammoniation method; step 2, mixing straw powder with clay, bentonite, Seeds and sodium humate are evenly mixed to obtain mixture A, and the water content of the clay is 10-16%; step 3, film-forming through a corrugated drum film-forming machine to obtain grass mat; the grass mat in the present invention not only plays the role of The function of windproof and sand-fixing can prevent dust and soil erosion in dusty environment.

Description

technical field [0001] The invention relates to the field of greening and environmental protection, in particular to a fast-growing grass felt and a preparation method thereof. Background technique [0002] In the fields of highway, railway, water conservancy, mining, municipal engineering and other engineering fields, it is often necessary to protect and green the damaged slopes to prevent desertification and soil erosion from causing natural disasters. [0003] At present, the method of slope protection is generally afforestation, but it cannot achieve a good governance effect. The reason is that it is difficult to solve the flow of water and soil. When the trees have not grown, the water and soil loss is already serious. The speed of planting trees is not as fast as the speed of desert expansion and water and soil loss. Therefore, it has been difficult to achieve significant improvement in governance. Effect. [0004] In addition, the main materials currently used for d...
