It is propagated mainly through grafting,and is suitable for popularization and application in the landscape of the Yangtze River basin and north of the Yangtze River.展开更多

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
