Background: Gaseous matter exchanges in soil are determined by the connectivity of the pore system which is easily clogged by fresh root exudates. However, it remains unclear how a hydrogel (e.g., mucilage) affects soil pore tortuosity and gas diffusion properties when drying.

植物可能通过粘液控制土壤气体交换

背景: 土壤中的气态物质交换由孔隙系统的连通性决定，该孔隙系统很容易被新鲜的根系分泌物堵塞。然而，目前尚不清楚水凝胶（例如，粘液）在干燥时如何影响土壤孔隙弯曲度和气体扩散特性。
