摘　　要：以钙镁磷肥、过磷酸钙、火烧土为基肥,分别和黄心土进行不同质量比的混合,得到15个培育基质进行黎蒴栲容器育苗试验。结果表明:处理12(90%黄心土+10%火烧土)育苗效果最好;其次是处理1(98.8%黄心土+0.2%钙镁磷)和处理6(98.8%黄心土+0.2%过磷酸钙),但这2个处理幼苗的叶片叶绿素含量均比对照(纯黄心土)低;添加火烧土大于20%或钙镁磷大于0.4%或过磷酸钙大于0.6%的处理,对黎蒴栲容器苗产生了负面影响。15 types of substrates with yellow soil as base,different proportions of calcium magnesium phosphate,superphosphate,and burned soil added as the basal fertilizers were applied for container seedling breeding experiment for Castanopsis fissa tree species.The experiment showed that the best result was obtained by treatment No.12（90% yellow soil ＋ 10% burned soil）,followed by treatment No.1（98.8% yellow soil ＋ 0.2% calcium magnesium phosphate）,and treatment No.6（98.8% yellow soil ＋ 0.2% superphosphate）.The chlorophyll content of the seedling leaves bred with the latter two treatments was both lower than that of the control（pure yellow soil）.When the burned soil was over 20%,or calcium magnesium phosphate was over 0.4%,or superphosphate was over 0.6% supplemented to the substrate,there seemed to be negative effect on the container seedlings of C.fissa.
