Embodiment 1

[0050] Embodiment 1: prepare superabsorbent material (superabsorbent, SAP)

[0051] As a super absorbent material, sodium polyacrylate powder was prepared.

Embodiment 2

[0052] Example 2: Preparation of Soil Fixative

[0053] 25g of hydrophilic colloid particles extracted from Plantago seeds, 180g of anionic polymer and 100g of compound fertilizer were dissolved in 4L of water to prepare a soil fixative.

Embodiment 3

[0056] Example 3: Biological soil crust formation using algae, superabsorbent materials and soil fixatives

[0057] 3-1. Prepare algae

[0058] From the soil collected in Ningxia, China in 2012, dry-resistant algae (Nostoc sp.) were isolated and inoculated into a transparent acrylic (acrylic) culture tank with a size of 100cm (horizontal) × 50cm (vertical) × 30cm (height), and one After one month, it was separated by centrifugation, and only the precipitate was collected. In the lower part of the culture tank, a water flow electrode is installed to allow the culture solution to flow evenly, and an air supply device is fixed in the center to supply air. The culture medium is BG-11 (BOSUNG SCIENTIFIC Co., Ltd, Korea). Considering the non-completely sealed structure and the large amount of culture fluid above 100L, it is difficult to sterilize it. Use after cleaning and sterilizing. The culture was carried out in a culture medium (PGW 36, Conviron, Canada) maintained at a temp...

Abstract

The invention relates to composition for ecological restoration using of barren land including alga, culture medium of the alga, soil fixing agent and ultra water absorbing materials, and a method for restoring the degraded ecology by them. According to the invention, biological soil crust can be formed in a short time; desertization and yellow sand can be avoided; waste coal mine and oil polluted land are improved into an ecological environment suitable for growth of plants; and ecological and environmental pollution caused by desert, waste coal mine and oil polluted land can be avoided.

Description

technical field [0001] The present invention relates to a composition for ecological restoration and an ecological restoration method using the same, in particular to the manufacture of a composition for ecological restoration that can effectively form biological soil crusts on barren land soil in a short period of time, and to introduce this composition to barren land To restore the ecological environment to an ecological environment that allows plants to grow. Background technique [0002] Biological soil crusts (BSCs) are a common habitat type on soil surfaces in dry regions and are known to perform ecologically important functions. The biological soil crust is composed of microorganisms such as cyanobacteria (cyanobacteria), green algae (green algae), lichens (lichen), mosses (mosses), actinomyces (actinomyces), filamentous fungi (filamentous fungi) and their The secreted substance is combined with the organic matter in the soil and the soil lining. The conjunctiva (cr...
