Soil water storage and preservation planting method for desert and arid areas

Abstract

The invention discloses a soil water storage and preservation planting method for a desert and arid areas. The planting method is characterized in that a layer of sand and cement concrete water storage tank or a plastic water storage tank is laid 0.3-3 meters under the ground of a desert or arid area, the water storage tank is filled with sandy soil, and plants are planted in the sandy soil. The soil water storage and preservation planting method has the following advantages: 1, the rainwater in the desert and arid areas does not permeate into the ground deeply, but permeates into the water storage tank, the root system of a plant can reach the water storage tank and absorb the water, the high soil moisture content is retained enduringly, and the normal growth of the plant is guaranteed; 2, the water irrigated by water conservancy facilities also permeates into the water storage tank, the water can be provided for a long time after one time of irrigation, the soil moisture content is greatly improved, the high soil moisture content is retained enduringly, abundant water can be provided for the growth of the plant, the water use efficiency is improved, and the cost of the water is reduced; and 3, the method is easy to carry out, can be used for a long time after one time of investment, and can be used for several tens or hundreds of years, the cost per year is not high, and the maintenance is not needed.

Description

technical field [0001] The invention relates to a planting method, in particular to a planting method for water storage and moisture conservation in deserts and arid regions. Background technique [0002] The difficulty in growing plants in deserts and arid areas is caused by water shortage, which is determined by the loose and fast water seepage characteristics of sand and sandy soil. In deserts and arid regions without water conservancy irrigation facilities, plants depend on precipitation from the sky to maintain their growth. It is not that there is no precipitation in desert areas, but that it is difficult for deserts to store water. The water that falls quickly seeps deep into the ground through the desert, and the roots of plants cannot reach and absorb water, making it difficult to survive. It is not that there is no precipitation in arid areas, but the amount of precipitation is small. The water that falls penetrates the surface soil and penetrates into the deep so...

AI Technical Summary

Problems solved by technology

Even in deserts and arid areas with water conservancy irrigation facilities, due to the high evaporation and loss of water and the high cost of water used for plant growth, it is difficult to plant plants on a large scale, resulting in a large amount of land being idle, which not only wastes land, but also damages the environment.
