摘　　要：在黔中地区 7种不同岩性发育的土体上 ,用实验生态学方法进行猴樟栽植试验 ,3a试验结果表明 ,不同岩性土体对猴樟的生长影响显著。从树高与地径的生长来看 ,以在灰质白云岩上生长最好 ,其次为玄武岩与变余砂岩 ,而以在煤系砂页岩、石英砂岩、紫色砂岩与第四纪红色粘土上的生长较差。表明猴樟对土壤有较广泛的适应性 ,但更适生于微酸至微碱性的通透性能与保水、保肥性能良好的砂质壤土及壤土。The Cinnamomun bodinieri LAe'G4vl.young trees were planted at soils from seven rocks using the experimental ecology method.The results of three years showed that the effects of soils on the growth of Cinnamomum bodinieri LAe'G4vl. were significant.The trees had a wide adaptation,grew well at limestone,basalt and metamorphic sandstone,but poorly at sandy shale and quartz sandstone; Cinnamomum bodinieri LAe'G4vl.adapts itself well at the sandy soil and loam with a good condition of irrigation and fertile.
