the root exudate-microbes interaction of Quercus mongolica and Tilia amurensis to light-water changes

high fluctuating light, high light steady state, and low fluctuating light, low light steady state; and three water gradients, 20% (extreme drought), 40% (moderate drought), and 60% (control) of field water holding capacity, totaling 12 treatments.本数据集涵盖4类光照处理：高光波动条件、高光稳态条件、低光波动条件以及低光稳态条件；同时设置3个水分梯度，分别为田间持水量的20%（极端干旱）、40%（中度干旱）与60%（对照），总计12个试验处理组合。
