摘　　要：以蔗渣、木屑为原料做尾叶桉容器育苗基质 ,进行不同配方、堆沤及追肥处理的试验 .结果表明 :木屑、蔗渣经过配比、堆沤、追肥处理后可以作为尾叶桉容器育苗的基质 .配方以V(木屑或蔗渣 )∶V(煤渣 )∶V(黄心土 ) =5∶2∶3最好 ,其次为配以 φ为 4 0 %煤渣 .经堆沤后 ,基质的N、P、K含量明显上升 ,苗木生长指标提高 .育苗性能优于或同等于泥炭的基质为 :(1)V(木屑 )∶V(煤渣 )∶V(黄心土 ) =5∶2∶3;不堆沤用追肥 2 (每株施尿素 0 .4g +KH2 PO40 .2g) ,堆沤 3个月用追肥 1(每株施尿素 0 .8g +KH2 PO40 .4g) ,堆沤 6个月不追肥 .(2 )V(木屑 )∶V(煤渣 ) =6∶4 ,V(蔗渣 )∶V(煤渣 )∶V(黄心土 ) =5∶2∶3,V(蔗渣 )∶V(煤渣 ) =6∶4 ;堆沤 3个月用追肥 1,堆沤 6个月用追肥 2 .(3)纯蔗渣堆沤 6个月 ,追肥Bagasse and sawdust were composted and mixed with coal ash and yellow soil, and evaluated as a substitute for peat in container medium on growth of Eucalyprus urophylla at 60 days old under 3 level's fertilization . The results showed that the following mediums were significantly better or equal to peat: 1) V (sawdust)∶ V (coal ash)∶ V (yellew soil)=5∶2∶3, fertilized with level 2,or fertilized with level 1 and composted for 3 months; or composted for 6 months and not fertilized. 2) V (sawdust)∶ V (coal ash)=6∶4, V (bagasse)∶ V (coal ash)∶ V (yellew soil)=5∶2∶3, V (bagasse)∶ V (coal ash)=6∶4. These 3 medium composted for 6 months and fertilized with level 2, or composted for 3 months and fertilized with level 1.3) Bagasse composted for 6 months and fertilized with level 2. Moreover, the mechanism of seedlings growth in medium was discussed.
