Background
Desertification seriously threatens the living environment of human beings and the development of socioeconomic performance, and at present, the desertification area of China reaches 262 ten thousand square kilometers and accounts for 27% of the territorial area. Meanwhile, china is one of countries with large desert areas, wide distribution and serious desertification hazard in the world. Desertification not only causes ecological system unbalance, but also continuously reduces the arable area, and has serious influence on industrial and agricultural production in China and life of people. Therefore, the control of desertification and desertification areas is an important content of current ecological construction. At present, however, desert control mainly relies on fixing grass square grids and planting drought-tolerant plants, the grass square grids have high desert control cost, and the grass square grids have large labor capacity and are difficult to implement in a large area.
Disclosure of Invention
The invention aims to provide an original ecological desert control method aiming at the problems existing in the prior art.
Another object of the present invention is to provide a comprehensive desert control device for implementing the above method.
Therefore, the invention adopts the following technical scheme:

(1) Preparing slurry: taking desert yellow sand, cement and gypsum powder as raw materials, adding water, and stirring to form slurry, wherein the solid-liquid ratio of the slurry is 100:25-40;
(2) And (3) slurry paving: spreading the slurry on the surface layer of the desert, covering the desert area to be treated, and controlling the thickness of the slurry to be 3-10cm;
(3) Breaking slurry: cutting the paved slurry to form 3-10cm block or spherical material blocks on the desert surface layer, and forming vegetation growing grooves in gaps among the material blocks.
Further, in the step (2), seeds of herbaceous plants suitable for growing in the desert are scattered on the surface layer of the desert before the slurry is paved, and then the slurry is paved.
Further, in the step (1), the raw material ratio of the slurry is as follows: 60-80 parts of desert yellow sand, 5-15 parts of cement and 5-15 parts of gypsum powder.
Further, in the step (1), the raw material of the slurry further comprises 5-10 parts of laterite or clay.
Further, in the step (1), the raw material of the slurry further comprises 2-5 parts of limestone.
Further, in the step (2), arbor isolation belts are planted on the west side of the desert area to be treated, and then slurry spreading is started.
The desert comprehensive treatment device for implementing the method comprises a slurry spreading mechanism and a slurry breaking mechanism, wherein:
The slurry spreading mechanism comprises a hopper and a stirring shaft horizontally arranged in the hopper, stirring blades are arranged on the stirring shaft, and a discharge hole is formed in the bottom of the hopper;
The slurry breaking mechanism comprises a frame, a sliding rod and a hook harrow, wherein the frame is fixedly connected with the rear side of the hopper, the sliding rod is horizontally sleeved on the frame, one end of the sliding rod is connected with a driving mechanism, the driving mechanism can push the sliding rod to reciprocate along the axial direction of the sliding rod, and a tension spring is connected between the sliding rod and the frame; the sliding rod is connected with a plurality of groups of hook harrows.

In the invention, staggered block-shaped or spherical material blocks are formed on the desert surface in a full-coverage mode, so that the desert yellow sand can be effectively solidified, and the formation of quicksand is prevented. The sowed grass seeds can grow out along vegetation growth grooves among the blocks and can not be buried by the quicksand, meanwhile, the covered blocks can effectively reduce the evaporation of water vapor in the desert, and the functions of preserving soil moisture and conserving water are realized, so that the ecological management of the desert is realized. In addition, the size of the material block is not too large or too small, the material block is easy to blow by strong wind, the area of a vegetation growth groove is easy to be smaller due to the too large material block, and the size of 3-10cm is the optimal size through experiments.
When the slurry is prepared, gypsum powder, laterite and the like can play a role in binding, meanwhile, the addition of the gypsum powder and limestone is beneficial to the slow decomposition of the material blocks, according to experiments, the material blocks can be naturally decomposed after 3-5 years, at the moment, vegetation in a treatment area has a certain scale, and the sand fixing effect of the material blocks is not obvious, so that the material blocks are required to be naturally decomposed after 3-5 years, and the vegetation area is conveniently enlarged.
In addition, due to the fact that western wind and northwest wind weather in desert areas are high, isolation belts formed by trees such as poplar, pagodatree, salix rubra and the like are planted on the western side of a treatment area, so that the material blocks are prevented from being covered by flowing sand in the initial stage of treatment, and the treatment effect is ensured.
In summary, the invention has the following beneficial effects: the treatment efficiency is high, and the method can be implemented in a large area in the edge area of the desert; the treatment cost is low, the raw materials are cheap and easy to obtain, and the local materials can be obtained; can effectively support moisture, avoid vapor evaporation and facilitate the growth of plants; the sand fixation can be effectively realized, and the formation of quicksand is greatly reduced; the treatment period is short, and the effect can be achieved about 3 years; the method is simple and suitable for popularization.
