【Objective】The effects of different intercropping modes on nitrogen in Camellia oleifera seedlings were explored,to provide a theoretical and scientific basis for improving the economic benefits of agroforestry complex ecosystem and promoting ecosystem diversity,so as to improve the fruit yield of Camellia oleifera in the later stage.【Method】Taking the 2-year-old Camellia oleifera seedlings as the research object,15N tracer method was used to explore the absorption,utilization and distribution of nitrogen in soil under three nitrogen levels...
