Embodiment 1

[0017] Carry out sand-fixing construction on a dune to prevent its further migration. Dry 32.5# ordinary Portland cement, bentonite, fertilized municipal solid waste, agricultural waste, pre-germinated sand shrub seeds and sodium polyacrylate at a ratio of 4:12:3:0.5:1:0.04 Mix evenly, then add clean water according to the water-solid weight ratio of 0.5 and mix evenly to produce a highly water-absorbing and environmentally friendly ecological sand control material slurry, which is loaded into a concrete mixer truck and transported to the designated sand dunes, in parallel strips or wells Spray the slurry on the surface of the sand dunes to form a 5-10mm thick sand-fixing layer. After construction, spray water on the newly laid vegetation in a timely manner to replenish water for the plant seedlings, and then effectively manage them to form green vegetation.

Embodiment 2

[0019] Manage a desert. Mix 1 part of 42.5 ordinary cement or 52.5 ordinary cement, 6 parts of bentonite, 2.5 parts of fertilized urban waste, 0.5 part of crop straw, 1 part of pre-germinated sand shrub seeds, and 0.022 part of sodium polyacrylate, and then press 0.5 parts of water Add clean water to the solid weight ratio, mix evenly in the concrete mixer truck, transport it to the designated place, and spray it on the sand surface in a parallel strip or well-shaped grid layout to form a 5-10mm thick sand-fixing layer. Two days after construction, spray water on the newly laid artificial vegetation to replenish water for the plant seedlings, and then effectively manage them to form green vegetation.

Embodiment 3

[0021] The preparation method of highly water-absorbing environment-friendly ecological sand control material, the steps are as follows: 1). By weight, it is 52.5 ordinary cement: bentonite: fertilizer-based municipal solid waste (through technologies such as composting, mechanical pulverization, microbial decomposition, domestic waste is converted into Organic biological fertilizer): agricultural waste (such as livestock and poultry manure): pre-germinated sand shrub seeds (such as salix): super absorbent resin (such as sodium polyacrylate) = 3: 8: 2.8: 0.8: 1: 0.03, Select solid raw materials; select water according to the water-solid weight ratio=0.45; 2). First dry mix cement, bentonite, fertilized municipal solid waste, agricultural waste, pre-germinated sand shrub seeds and superabsorbent resin, Add water and stir evenly to obtain a highly water-absorbing and environmentally friendly ecological sand control material slurry.

[0022] To control the desert, put the slurry ...

Abstract

An environment protection type high-hydroscopicity material for controlling desert is proportionally prepared from cement, bentone, fertilizer prepared from life garbage, rejected agricultural material, pre-germinated seed of sabulose shrub, high-hydroscopicity resin and water.

Description

technical field [0001] The invention belongs to the field of sand-fixing materials, and in particular relates to a multifunctional ecological sand-control material integrating urban domestic waste treatment, agricultural waste treatment and vegetation restoration and a preparation method thereof. Background technique [0002] Land degradation has attracted extensive attention from international organizations, governments, research institutions, land management departments and the public worldwide in recent decades. Land degradation, also known as land desertification, refers to the decline of land productivity and the loss of land resources caused by the interaction between human irrational economic activities and fragile ecology, and the land surface presents a landscape similar to desertification. The direct causes of land degradation are as follows: on the one hand, the ecosystem itself of degraded land is relatively fragile, with poor anti-interference ability, stability...
