通过研究赣南离子型稀土残矿区不同植被恢复模式下其植被恢复情况及土壤改良情况,分析3种模式的治理效果,研究对比不同经营措施及类型苗木下主要树种生长差异性,结果证明3种模式均能够有效恢复植被并有效提高残矿区的土壤养分,其中以桉树林分生物量及郁闭度最大,黄竹分殖苗其次。不同配比施肥对桉树高生长有显著差异,其中以N3P1K2配方最佳,不同类型黄竹苗出笋量无明显差异,但分殖苗出笋数量大于繁殖苗。
Through the study of vegetation restoration and soil improvement under different vegetation restoration patterns in southern Jiangxi ionic rare earth residue area, the effects of three kinds of patterns were analyzed, and the differences of growth of main tree species under different management measures and types of seedlings were compared. The results showed that three kinds All the models can effectively restore the vegetation and effectively improve the soil nutrients in the residual ore area. Among them, the eucalyptus stands have the highest biomass and canopy density and the second is the rhizobia. Different fertilization had significant differences on the height growth of Eucalyptus. Among them, N3P1K2 had the best formula and no significant difference in the amount of bamboo shoots, but the number of bamboo shoots was higher than that of the breeding seedlings.
