Abstract

The invention provides a preparation method of a desert alga-type attapulgite-based polymer sand stabilization material. The preparation method comprises the following steps: pretreatment and expanding propagation of desert alga crusts, pretreatment of attapulgite and preparation of attapulgite-based super absorbent resin; and preparation of the desert alga-type attapulgite-based polymer sand stabilization material, wherein the desert alga crusts are compounded with the attapulgite-based super absorbent resin to obtain the desert alga-type attapulgite-based polymer sand stabilization material.According to the preparation method, artificially cultured desert algae and the synthetic polymer material are combined to be applied to desertification control, the advantages of fast effectivenessand good sand stabilization effect of a chemical sand stabilization material are kept, and the characteristics of strong vitality, high adaptability to the environment in desert areas, capability of improving soil fertility, and the like of the wild lower plant-desert algae in the desert area are also utilized, so that a positive effect is exerted in subsequent vegetation recovery and ecological succession in the areas. Therefore, the problems of vegetation in desertification land and restoration of production capacity are solved.

Description

technical field

[0001] The invention belongs to the technical field of sand prevention and sand fixation, and in particular relates to a preparation method of a desert algae-type attapulgite-based polymer sand fixation material. Background technique

[0002] In desertification control, sand-fixing materials and sand-fixing technology complement each other and play an equally important role. At present, the mainstream sand fixation technologies mainly include engineering sand fixation technology, chemical sand fixation technology, biological sand fixation technology and comprehensive sand fixation technology. Comprehensive sand fixation is to achieve the purpose of comprehensive control through the combination of conventional engineering sand fixation technology, chemical sand fixation technology and biological sand fixation technology. In recent years, comprehensive sand fixation technology has become increasingly mature, many scholars have done a lot of research, and new s...

Embodiment 1

[0043] 1. Research materials:

[0044] 1 desert algae crust material. Randomly set 32 ​​sampling points on the southern margin of the Tengger Desert, Shapotou, Ningxia (37°31′15″N latitude 37°31′15″E, 105°2′16″E) Small shrubs above 20cm), use a small shovel to collect samples of wild algae (algae species are mainly cyanobacteria) crusts with a complete surface, the sampling depth is 1-2cm, save the samples in sealed plastic bags, and bring them back to the laboratory. After the collected samples were sieved, they were repeatedly soaked and rinsed with distilled water to separate the pure algae. In the BG11 medium, at 25±1°C, the light intensity was 120 μE·m -2 ·s -1 Placed in a light incubator for cultivation under certain conditions, for later use.
