Water retention device suitable for planting plants in arid regions

Abstract

The invention provides a water retention device suitable for planting plants in arid regions. The water retention device comprises a water retention bag, wherein the water retention bag is a plantingbag with an open top end and a semi-elliptical cross section; the side edge of the water retention bag is provided with air holes, nutrient soil is placed in the bag body of the water retention bag, and the open top end of the water retention bag is covered with a gravel layer above the nutrient soil. The water retention bag has water-retaining and water-saving functions in the using process, canincrease the survival rate of plants in the initial growth stage, is made of cellulose-based super absorbent materials or wheat straw super absorbent resin, can be degraded in the middle and later growth stages of the plants, and does not affect development of the plants and avoids waterlogging. Nutrient soil in the water retention bags provides nutrient substances for plant growth, meanwhile, thesandy soil layer on the surface layer of the nutrient soil can increase the weight of the nutrient soil to avoid loss of the nutrient soil and block capillary water, the planting survival rate of plants in loess plateau arid areas can be increased, and the ecological restoration effect can be improved conveniently.

Description

technical field [0001] The invention belongs to the technical field of plant planting devices in arid areas, and in particular relates to a water retention device suitable for planting in arid areas. Background technique [0002] With the adjustment of my country's economic layout, my country's Loess Plateau has been greatly impacted, and the phenomenon of water and soil loss is relatively serious, and it is an area with relatively fragile ecology. The Loess Plateau lacks natural vegetation coverage, poor soil quality and water shortage, which greatly limits the development of the Loess Plateau. In order to change this status quo, it is necessary to solve the problem of ecological deterioration as soon as possible. Strengthen the construction of ecological restoration projects to improve the existing ecological environment, and realize the self-repair and reconstruction model to restore and rebuild vegetation on the basis of not violating the law of natural development. ...

AI Technical Summary

Problems solved by technology

The ultimate cause of these problems is due to the desiccation of soil in the Loess Plateau and the shortage of water resources.

In the early stage of growth, the excess water will spread to the surroundings and evaporate during irrigation, resulting in a waste of water resources. Insufficient water supply will cause plants to wither and die, wasting financial resources
