Desert soil moisture conservation method and application

Abstract

The invention provides a desert soil moisture conservation method and an application, belonging to the technical field of desert transform. Original resources are used for transforming the desert, a soil layer is reconfigured to build soil moisture conservation ridges, fine earth, sandy soil and gravel fill back from the bottom up, and the gravels are stacked at one wind block side of the ridge. The invention utilizes the original resources to apply the no-irrigation conservation of desert by adjusting measures to local conditions. The application are as follows: the conservation ridges are used to plant cash crops, and a large area of wild flowers and wild grasses are planted to realize desert oasis, thus not only improving the soil texture of desert areas and the growing environment of cash crops, and but also alleviating lack in the water source because rainfall is rare and ground water is difficult to use and the like. In addition, the invention can solve the problems of strong wind power, difficult growth for plants and the like in gobi desert areas; while the desert transform is applied to obtain good social effect, the invention can plant the cash crops to obtain preferableeconomic benefit.

Description

technical field [0001] The invention relates to the technical field of desert transformation, in particular to a method for preserving moisture in deserts based on reconfiguration of soil layers (not through irrigation), and a new type of ridge suitable for planting formed after transformation. Background technique [0002] With the deterioration of the earth's climate and environment, land desertification is becoming more and more serious, resulting in less and less arable land resources. How to transform deserts is a worldwide problem. Planting trees and grasses in the desert is a way out for desert transformation. However, large areas of desert land (such as the Hami area of ​​China) have little rainfall and frequent sandstorm activities all year round. Environmental conditions are not suitable for large-scale planting of vegetation. [0003] CN1669369 (200510070972.9) discloses a method for interplanting natural plants in desertified sandy land, the steps are as follows...

Problems solved by technology

[0007] With the above design, the present invention uses the original resources to adapt measures to local conditions to implement the desert without irrigation to conserve moisture. By reconfiguring the soil layer, the original soil is divided into three categories: gravel, sand and fine soil, and then the classified soil is used to rebuild. The length and depth of the new moisture-retaining ridge, and then plant economic crops such as Haloxylon and Cistanche on the new-type ridge, and build a new type of moisture-preserving ridge that can improve the soil quality of the desert (such as the Hami area) and the growth environment of Haloxylon and Cistanche. It solves the shortage of water resources caused by the lack of precipitation and the difficulty of using groundwater, and it can also solve the problems of strong wind and difficult plant growth in the desert Gobi area.
