摘要
针对雷州半岛桉树林出现的桉红叶枯梢病,进行施微肥的田间试验。结果表明单施硼对刚果12号W 5无性系和U6无性系有明显的防治效果;硼与铜、铁、锰、锌等配施效果明显好于单施硼;桉树不同树种对微量元素营养有一定的选择性,硼与铜、锌、铁、锰等配施可使刚果12号W 5大幅增产,而硼与钼配施对尾叶桉U6生长效应显著;施用硼可有效消除雷州半岛桉树的桉红叶枯梢病。
This paper summarized the investigation about application B microelement art and fertilize with other microelement on Eucalyptus from 1998 to 1999, and the results as follows: (1)Both Eucalyptus ABL 12 W5 and Eucalyptus urophylla S. T. Blake U6 is display fine effect which only B microelement fertilizer, but E. ABL 12 W5 is better than E. urophylla U6. (2)In spite of some selection is exist in Eucalyptus, the better effect is showed in application B microelement fertilize with Cu, Fe, Zn, Mn than sole B microelement fertilizations, and the yield of E. ABL 12 W5 is increased for big range, the fine effect was showed in E. urophylla U6 which application B and Mo microelement fertilizations. (3) Lack of B microelement is an important factor of physiology on Eucalyptus, and fertilize B microelement fertilizer can eliminate it.
