| 摘 要： | 在江西赣州市对巨桉优良无性系巨G1、巨G2按随机区组,3次重复10小区进行不同施肥量试验,应用方差分析与多重比较的数理统计方法得出:A3B2处理(每株施基肥0.5 kg,追肥0.25 kg)为巨桉速生丰产最佳施肥量,其3 a生蓄积量达121.32 m3/hm2,比A2B2处理(每株施基肥0.25 kg,追肥0.25 kg)蓄积量88.01m3/hm2高出37.84%。

| Abstract: | Fertilizer application test in different amount was conducted by using Gland G2 with random- ized block, three repetitions of 10 quarters, taking methods of variance analysis and mathematical statis- tics of multiple repeated comparison, results showed： treatment A3B2 （0.5kg per plant applying base fertilizer, topdressing O. 25kg） was optimum fertilization for fast growing of superior clones of Eucalyptus grandis, the volume of three year Eucalyptus grandis reached to 121.32m3 which 37.84% higher than treatment A2B2 （0.25kg per plant applying base fertilizer, topdressing 0.25kg ） volume 88.01m3. |
