| description | The decomposition of litter plays an important role in the return of forest soil nutrients, as well as the growth and productivity of plants. With this study, we aimed to determine the impact of litter mulching on different tissues of <i>Cinnamomum migao</i>, a rare Chinese endemic species. In particular, seeds and pericarp are easily overlooked components of <i>C. migao</i> litter. In this study, we tested control (uncovered litter) and litter (leaf, branch, seed, and pericarp) mulching conditions and conducted a one-year litter decomposition experiment. The enzyme activities of urease enzyme (UE) and invertase enzyme (INV) were significantly improved by litter mulching. Catalase (CAT) enzyme activities in leaf, branch, and seed litter mulching were lower than in the control, whereas CAT activity in pericarp mulching was significantly higher than in the control. Although <i>Mortierella, Cladophialophora</i>, <i>Acidothermus</i>, <i>Sphingomonas</i>, and <i>Burkholderia</i> were the dominant microbes of topsoil in different mulching treatments, there were differences in the number and connectivity of microbial communities, and this change was correlated with soil organic carbon (SOC) and CAT enzyme activity. Compared with leaves and branches, seeds and pericarp as litter are also very important for nutrient return and affect topsoil microbes in <i>C. migao</i> forest, which may be of significance for the growth feedback of <i>C. migao</i> in biennial bearing. |
