Problems solved by technology

This method of construction is extremely inconvenient and has great limitations. Most chemical products contain toxic substances, which are difficult to degrade in nature and pollute the environment. Some harmful substances seep into the groundwater system with water, which does not meet environmental protection requirements. Petroleum products and by-products Applying it to the desert affects the distribution of water sources in the sand layer, and the rainfall cannot penetrate evenly under the sand layer, resulting in a decrease in the surface water level in the desert and the death of sand plants

Embodiment Construction

[0038] The spraying slurry in the present invention is composed of crop straw, viscous loess or laterite, plant water-retaining agent, binder, cotton wool fiber, compound fertilizer, trace element fertilizer, modified gypsum, cattle and sheep manure, and wooden sawdust. Among them, according to the geographical conditions of the greening, appropriate adjustments can be made during use, for example:

[0039] Quicksand state and steep slope state, can increase the consumption of binder component, use embodiment A; Reduce the consumption of binder component under mixed type soil condition, use embodiment B; Under alkaline soil condition, can Increase the amount of phosphoric acid component, use Example C; in the steep slope state, you can increase the amount of modified gypsum component, use Example D; in the area with sufficient water source, you can choose economical and applicable trees and shrubs , can choose heat-resistant, cold-resistant, drought-resistant grasses, shrubs p...

Abstract

A method for fixating sand while growing plants by spraying slurry to form a cover layer on the surface of desert or ground includes such steps as proportionally preparing slurry from water, strew or stalk or industrial fibrous dregs, adhesive loess or laterite, water-preserving agent, adhesive, cotton or wool fibres, composite fertilizer, trace element fertilizer, modified gypsum, ox(or sheep) dung, saw dust, phosphoric acid and plant seeds, and spraying it onto surface of desert or ground. Its advantages are high effect and low cost.

Description

technical field [0001] The invention relates to the technical field of sand fixing and greening environment protection, in particular to a method for sand fixing and greening by spraying and spraying to form a covering layer. technical background [0002] At present, sand fixation in the world is divided into two categories: mechanical sand fixation and chemical sand fixation. Common mechanical sand fixation methods include: artificial grass grids for sand fixation; vertical fence sand barriers for sand fixation; nylon mesh fence sand barriers for sand fixation; Sand fixation by soil clod, soil layer and stone covering method. This method is labor-intensive and time-consuming, has poor durability, is difficult to construct, and has little ability to resist wind. Common chemical sand fixation methods include: petroleum and by-product asphalt sand fixation; cement layer sand fixation; water glass sand fixation; polymer chemical materials sand fixation. This method of constru...
