Problems solved by technology

[0002] The slope soil of arid saline-alkali land has the characteristics of lack of humus, loose soil and easy collapse, weak erosion resistance, sparse vegetation, low nutrient content, slow soil formation process, and extremely poor soil fertility and water retention. Due to the mechanical properties and complex and changeable climate and environmental conditions, various disasters such as gullies and erosion have occurred on these slopes, causing serious soil erosion and destroying the ecological landscape. How to restore the original ecological vegetation of the arid saline-alkali slope Research topics at home and abroad
[0003] At present, although there are many patented technologies on saline-alkali soil slope regreening in China, the ecological restoration technology for special environmental conditions in arid and semi-arid areas is not yet mature enough, the pertinence is not strong, the effect of slope regreening is poor, and the cost is expensive

Abstract

The invention provides a spray-seeding matrix applicable to regreeening of slopes of droughty saline and alkaline land, and a preparation method thereof, belonging to the technical fields of improvement of saline and alkaline land and greening matrixes for slopes. The spray-seeding matrix comprises the following raw materials by weight: 30-40 parts of decomposed organic waste, 35-45 parts of alienearth, 5-15 parts of bentonite, 5-10 parts of vegetable fibers, 0.5-0.8 part of halophilic and basophilic microbial agents, and 3-4 parts of a flour paste adhesive. The spray-seeding matrix allows plants to rapidly form dense aerial parts and developed roots on the slopes of droughty saline and alkaline land, thereby effectively realizing slope regreening, consolidating soil and preventing and treating surface runoff and soil erosion. The preparation method for the spray-seeding matrix provided by the invention comprises the following steps: mixing and pulverizing the decomposed organic waste, the alien earth and the bentonite so as to form particles, then mixing the particles with the plant fibers, adding water, carrying out stirring to allow the obtained mixture to be in a viscous state, and then mixing the mixture with the flour paste adhesive and the halophilic and basophilic microbial agents. The preparation method is simple technology, good in operability and favorable for industrial production.
