Optimizing the formulation of coal gangue planting

2020-1-15  The optimum composition ratio of the coal gangue planting substrate is as follows: coal gangue-to-soil ratio of 1:1 (500 g:500 g), maize straw content of 50 g kg −1, fly ash content of 37 g kg −1, and water retention agent content of 1 g kg −1. The results could provide a theoretical and technical basis for coal gangue ecological reutilization, land reclamation and vegetation restoration in coal-mining areas.
