不同施肥量对桉树生长的影响

Effects of Different Fertilizer Application Rates on the Growth of Eucalyptus

摘要: 为了探讨不同施肥量对桉树生长的影响，采用裂区设计试验，设置施肥量分别为500 g/株、800 g/株、1 100 g/株、1400 g/株等4个处理，研究不同施肥量对桉树树苗生长、光合特性和生物量的影响。结果发现：施肥量为1 100 g/株和1 400 g/株的树苗各项指标测定中差异均不显著，但二者显著高于施肥量为800 g/株和500 g/株处理的苗木测量指标，综合成本考虑,以施肥量为1 100 g/株对于桉树苗的生长最有利。

Abstract: In order to investigate the effects of different fertilizer application rates on the growth of Eucalyptus, a split plot design experiment was used to study the effects of different fertilizer application rates on the growth, photosynthetic characteristics and biomass of Eucalyptus seedlings. The results showed that there was no significant difference between 1 100 g/plant and 1 400 g/plant,but they were significantly higher than those treated with 800 g/plant and 500 g/plant. Considering the overall cost, 1 100 g/plant was the most beneficial for the growth of Eucalyptus seedlings.
