Method for preventing and fixing sands by using sheep manure

Abstract

The invention discloses a method for prompting rapid recovery of vegetation in a bare sandy land and a blowout pit by combining a thoroughly decomposed sheep manure biological crust with biological measures. The technology is mainly composed of techniques such as selection of suitable grass seeds and shrubs, shrub cultivation, direct seeding of grass seeds and pavement of thoroughly decomposed sheep manure. The method comprises the steps of: firstly, selecting types of grass seeds and shrubs suitable to be grown in highly cold desert regions, and then cultivating suitable shrubs in the bare sandy land and the blowout pit; secondly, sowing the suitable grass seeds; finally paving the thoroughly decomposed sheep manure on the surface of the quicksand. After a period of time, the thoroughly decomposed sheep manure biological crust is formed on the surface of the quicksand; the suitable plant seeds and the sheep manure form a tightly combined and mutually depended integral body; the thoroughly decomposed sheep manure provides nutrition to the growth of the suitable plant seeds, has heat preservation, moisture keeping and the like functions, can promote rapid growth of the vegetation, provides a steady growth environment, avoids flow of the quicksand and wind corrosion, and is more conductive to the recovery of the desert grassland. The method for preventing and fixing sands by using sheep manure has the advantages of fast sand fixation speed, low cost, low labor cost, long storage time, rapid and convenient construction, easy operation, no adverse effect for the environment and plants, and the like.

Description

technical field [0001] The patent of the invention belongs to the technical field of sand prevention and control, and specifically relates to a method for promoting the rapid recovery of vegetation in bare sand land and wind-eroded pits by combining decomposed sheep manure crusts and biological measures. technical background [0002] In recent years, under the superimposed influence of various factors such as global climate change, overgrazing, rat infestation, and human disturbance, land desertification in alpine regions has developed from sporadic distribution to local contiguous contiguous areas, presenting a trend of rapid expansion, which has affected regional ecological functions. Significantly affected. Although the combination of machinery and biology is currently the best technology for mobilizing sand dunes under site conditions similar to those in alpine regions, due to the special natural environmental conditions in alpine regions, this model has high costs and s...

Although the combination of machinery and biology is currently the best technology for mobilizing sand dunes under site conditions similar to alpine regions, due to the special natural environmental conditions in alpine regions, this model has high costs and slow construction, making it difficult to widely promote

Using the discarded sheep dung in pastoral areas as materials not only effectively utilizes the discarded sheep dung in pastoral areas, but also solves the problem of low efficiency and easy damage of artificial grass grids in sand control.
