This paper applied the pilot experiment method, and took Tulbaghia violacea and Malus micromalus cv. "American" as the test flower and tree to explore the impact of different biochar return-to-soil modes on plant growth. It was found that biocharcoveredsoil promoted the growth of both species efficiently, and relieved the poor growth, compared with the control group, biochar-covered-soil reduced yellow leaves, dead leaves and poor growth vigor of T.violacea by 47.8%, 20% and 100%, respectively, and it reduced poor growth, dead branch rate and root tiller germination of M. micromalus cv. "American" by 80%, 62.5% and 50%. The results showed that biocharcoveredsoil was better than biochar-mixing-soil.展开更多
