Description

Desertification soil ice-condensation type treatment method

Technical Field

The invention relates to the technical field of soil treatment, in particular to a method for treating desertification soil by condensing ice.

Background

At present, the climate and the soil drought in northwest regions are aggravated by warming the climate and reducing rainfall. This results in a reduced vegetation coverage in the area, a looser soil structure and an accelerated land desertification. In addition, the climate is heated, and the continuous drought in a large-scale climate brings serious influence to various water resources (glaciers, lakes, rivers and the like), so that the glaciers shrink back, the river water flow is reduced or is cut off, the lakes shrink, and the underground water level is reduced. Large-area vegetation dies due to water shortage, the function of protecting earth surface soil is lost, and the soil desertification speed is accelerated.

Soil desertification is defined as the degradation of land in arid, semi-arid and sub-humid arid areas caused by a variety of factors including climate variation and human activities. That is, the decrease or loss of soil productivity due to strong wind erosion, running water erosion, soil salinization, etc., may be referred to as desertification.

The existing method for treating soil desertification mainly adopts afforestation, but the method has large investment, slow effect and long period, can not directly prevent the evaporation and loss of soil moisture, and has small effect; in addition, the treatment methods such as spraying film and liquid mulching film are used in the area, but all can only play a role in a short time, and the soil desertification cannot be fundamentally treated. The desertified soil generally has the evaporation capacity larger than the rainfall capacity, plants are directly planted on the desertified soil, the effect of reducing water evaporation cannot be achieved, and the water condition of the soil inhibits the growth and survival of the plants on the contrary.
