To investigate the effects of biochar on the root growth and soil reinforcement capacity of slope vegetation in high-altitude regions, in this study, Yajiang County, Garze Tibetan Autonomous Prefecture, Sichuan Province, was selected as the experimental area, and <i>Lespedeza bicolor</i> was selected as the research object. Six biochar application gradients were established: 0 kg·m-2 (CK), 2.5 kg·m-2 (I), 5 kg·m-2 (II), 7.5 kg·m-2 (III), 10 kg·m-2 (IV), and 12.5 kg·m-2 (V). The effects of different application rates on the soil physical and chemical properties, root morphology, chemical composition, and tensile strength of L. bicolor were systematically analyzed. The results indicated that the biochar application rate significantly affected the root morphological and.. Read More»
