Microbial Chaff Reinforcement: Preparation and Performance Study of a Soil Stabilizer

Abstract

The fungus bran is the waste of the fruiting body of edible fungi, which is rich in a variety of protein and fiber, amino acids, polysaccharides, enzymes, and other nutrients, and has high reuse value. In this study, the fungus bran produced by desert Tremella was used as the raw material to prepare the fungus bran which could provide plant nutrients and water retention function. After 7 days of experiments, it was found that the sand fixation material had good water retention performance and significantly increased the aggregate performance of the sand. The results of FTIR and SEM analysis showed that the sand chaff was involved in the agglomeration process of sand, and the sand and the chaff were well combined, with a better spatial network structure and surface morphology. Therefore, it is a great prospect to explore the reuse of solid waste of fungal bran in desert afforestation.
