摘要
在总养分含量相同条件下研究了有机—无机复混肥A(包括基肥、追肥)、有机—无机复混肥B(包括基肥、追肥)、无机肥C 3种肥料处理对尾细桉生长的影响。结果表明施用有机—无机复混肥A的处理在苗木生长17个月的时候长势最好,与其他3种处理差异达到极显著水平。在生长30个月时,施用有机—无机复混肥A处理与B处理生长均较好,两者差异不显著,但是均与C处理差异显著。说明肥料和施肥方式会对尾细桉的生长有影响;添加有机质会提高桉树尾细桉的产量。
The impacts on growth of Eucalyptus urophylla × E. tereticornis from three fertilizer treatments （A, B, and C）, including base fertilizer and additional fertilizer that provided the same total amounts of key nutrients, were examined in this study. The results showed that the best growth to age 17-months was obtained with organic-inorganic fertilizer treatment A. This treatment proved significantly superior to the other two fertilizer treatments. At age 30-months, treatment A and B proved best with no significant difference between these two, whilst treatment C gave significantly inferior growth. It was concluded that alternative fertilizer formulations can significantly influence growth of E. urophylla × E. tereticornis, and that the inclusion of organic matter in the fertilizer formulation can significantly improve growth.
