Description

Water retaining device suitable for plant planting in arid region

Technical Field

The invention belongs to the technical field of plant planting devices in arid regions, and particularly relates to a water retention device suitable for plant planting in arid regions.

Background

With the adjustment of economic layout of China, loess plateaus in China are greatly impacted, the water and soil loss phenomenon is serious, and the method is an area with fragile ecology. The loess plateau lacks coverage of natural vegetation, and the loess is barren and lacks water, thus greatly limiting the development of the loess plateau. To change such a situation, it is necessary to solve the problem of ecological deterioration as much as possible in time. The construction of ecological restoration engineering is enhanced to improve the existing ecological environment, and the vegetation is restored and rebuilt in a self-restoration and rebuilding mode on the basis of not violating the natural development law.

In the ecological construction process of the loess plateau, a large amount of fast-growing seeds are cultivated in part of areas for seeking fast efficiency. Although the fast-growing seeds grow fast, the water demand is large, a soil dry layer is easily caused, and the survival rate is low. In the forestation of trees in partial areas, the artificial density of plants is high, a large amount of soil moisture is consumed, the reduction of the soil moisture content and the loss of moisture can cause the phenomena of withering and death of plants and the like. The final reason for these problems is the drying of soil in loess plateau areas and the shortage of water resources. The plants wither and die because the excess water is diffused to the surrounding to evaporate during the irrigation in the early growth stage, which causes the waste of water resources and the shortage of water supply and wastes financial resources.
