Method for sand treatment by using loam-like substrate spraying technology

Abstract

The invention discloses a method for sand treatment by using a loam-like substrate spraying technology. The method comprises the following steps that firstly, a simple sand-fixing treatment is carriedout, a layer of metal mesh is laid on the sand, and the metal mesh is fixed on the sand surface by a sand-fixing pile; secondly, seeds are sprayed on the sand through a loam-like substrate spraying method; after the completion of the spraying, the maintenance management work is required, which includes the addition of protective plates around the metal mesh, non-woven fabric covering, watering, fertilizing, replanting and post-monitoring. The method uses two-layer spraying for seeding, the loam-like soil suitable for plant growth in the natural world is rapidly simulated by bionics, and the good water retention performance is favorable for improving seed germination, is beneficial to root development, microbial activities and nutrient transformation, and promotes plant growth and development; the method is less input, has quick effect, and is suitable for large-scale sand control.

Description

technical field [0001] The invention relates to a method for controlling sandy land by using the loam-like substrate spraying technology, and belongs to the technical field of desert control. Background technique [0002] There are large deserts all over the world, and they are expanding rapidly. The frequency of sandstorms is getting higher and higher, and the damage caused is also increasing. Sand control, but in general, the speed of governance still cannot catch up with the speed of desertification, and the trend of local improvement and overall deterioration continues, and the situation of sand entering and people retreating has not been fundamentally improved. [0003] In the prevention and control of desertification, mechanical sand barriers are an important sand-fixing measure. They are deployed relatively quickly and have good wind-proof and sand-fixing effects. The characteristics of insignificant ecological and economic benefits are not conducive to long-term and...

Problems solved by technology

[0004] At present, the layout method of bio-desert overplanting mostly adopts the method of planting shrubs in strips. The tree species planted generally include sand-growing shrubs such as Azalea, Haloxylon, Salix, etc. The amount of water is low, regular irrigation and protection are required, a lot of manpower is invested, and the cost is high. Moreover, the above-mentioned plants grow slowly and have a low survival rate, and cannot quickly form the effect of windbreak and sand fixation
