[0008] The above method can indeed play a certain role in sand fixation, but it will consume a lot of water to cover with cement and bricks, while the method of using straw and straw can't keep the water well, and can't prevent sand well. sandstorm

Embodiment 1
[0028] Embodiment 1, the present embodiment is a method for controlling the desert by focusing sunlight, burning and melting the sand on the surface of the desert, making it harden, and preventing the evaporation of water on the shallow surface of the desert. The method for controlling the desert includes the following steps:
[0029] Step 1. Carry out high-temperature melting and sintering of the sand on the surface; in this step, a kind of focused sunlight is used to burn and melt the sand on the surface of the desert. After focusing, the sand around the focus can be burned and melted. Theoretically, the melting point of the sand is 1670°C (tridymite) to 1710°C (cristobalite). In practice, when the sun is focused, the temperature of the sand at the focus quickly decreases It can exceed 1700°C, therefore, the sand around the focus (5mm) will melt quickly, and after melting, it will bond with the surrounding sand that has not yet melted to form a circular hardening with a radiu...

Abstract
The invention provides a method and a device for controlling a desert. Sand on 50% or above of the desert surface is burnt, melted and hardened through high temperature, so that the sand is preventedfrom moving, and underground water is prevented from being evaporated. The device focuses sunlight to scan, sinter and melt the sand on the surface. The characteristic that solar energy and light in adesert area is abundant is made full use of by the method and the device; local materials are used; the sunlight is focused to burn and melt the sand on the desert surface, so that 50% or above of the desert surface is hardened, and the water on the desert surface is prevented from being evaporated; plants can be grown in hardened part gaps; soil improvement is conducted on the sandy surface of remaining places by growing the plants; drought-resistant economic plants can be selected for growing; in this case, certain economic benefits can be obtained in a sand-control and sand-stabilization process, the sustainable development is achieved, and with the adoption of the green sand-control method, the materials outside the desert are not required to be used.
Description
technical field [0001] The invention relates to the field of desert control, in particular to a desert control method and used equipment. Background technique [0002] The most powerful weapon to control the desert is water, but not only is there a shortage of water in the desert, but also because there are few clouds in the desert area, the weather is often sunny and dry, and the temperature of the sand under the sun is high, and finally some water will evaporate quickly. In this way, it is not conducive to the growth of plants in the desert. Since there is no plant cover, the water in the desert will evaporate more easily, and the sand will be carried away by the wind. More and more sand will be carried away by the wind to form flowing sand dunes, which will erode the desert. There are more and more arable lands, causing more and more serious damage to the desert, and it is more and more urgent to control the desert. [0003] The main weapon for controlling deserts is wat...
