摘要
桉树红叶枯梢病可施用硼、铜、锌等微量元素进行有效防治。设计了6种处理。其中,硼砂10 g+硫酸铜5 g组合对树高生长促进作用较大;硼砂10 g+硫酸铜5 g+硫酸锌5 g组合对减少丛枝以及减少红叶率效果较明显。春季施放效果好于秋冬季。春季施用20 d后就见效,50 d后病状基本消失,树体基本恢复健康。
Eucalyptus red leaf dieback could be controlled with the micro elements such as boron, copper and zinc. Six treatments were designed in the trial. The results showed that the mixture of 10g borax and 5g coppersulfate was the best for improving the height growth of young trees and the mixture of 10g borax ,5g zinc sulfate and 5g copper sulfate was the best for the reduction of witches＇ broom and red leaves of the young trees. The application in spring was better than that in winter and Autumn. In spring, the diseased trees grew well 20 days after the application and recovered 50 days after the application.
