摘　　要：采用不同用量复合肥和磷肥作基肥，研究其对巨桉幼林生长的影响。结果表明：各施肥处理与对照间株高、地径差异均达到5％显著水平；复合肥用量500g，株高2．04m、地径2．46cm，而磷肥用量500g，株高1．68m、地径1．77cm；用复合肥200g和磷肥300g混合作基肥，株高2．12m、地径2．53cm。相同用量时，复合肥施用效果好于磷肥，两种肥混施具有较好的促进桉树生长的作用。Different dosage of compound fertilizer and phosphate were used as basic fertilizer, and the effect was studied on sapling growth of Eucalyptus. Results showed that the height and diameter between the different treatments and control were significant different at 5% level; compound fertilizer 500g, plant height and ground di- ameter at 2.04m,2.46cm; phosphate 500g height 1.68m, ground diameter 1.77cm; with compound fertilizer 300g and phosphate 200g mixing, plant height 2.12m, ground diameter 2.53cm. When the same amount of fertilizer were applied, the effect was better with compound fertilizer, sampling growth was good with compound and phosphate.
