PILCs as Water-transmitting Material and Application in Planting Trees in Drought Areas
Clay-based water-transmitting materials were proposed in order to solve the problems of dry soil layer and watering during forest planting in drought areas. The pillared interlayered clay was prepared in the presence of primary bentonite. The conductivity property was investigated under various conditions of cross-linking agent ratio. The structural aspects and thermal degradation of composites were also studied by means of XRD, TG and porosity analysis. The results indicated that pillared clays modified by Al cross-linking agent exhibit higher water conductivity properties remarkably. Larger specific surface area, more pores and complicated pore structures play vital roles in the enhancement of the conductivity property. This kind of material can obviously elevate capillary water upward from subsurface aquifer to the roots of saplings in drought areas so as to improve the survival rate of the saplings.
