摘要
通过实地调查,利用土壤和叶片的营养诊断方法对广西贺州桉树萌芽林梢枯病致病原因进行分析,探讨广西桉树萌芽林梢枯病的发病原因及防治对策。结果表明:桉树萌芽林梢枯病主要由缺素以及其他经营管理措施不当相互作用引起。提出以加强施肥管理、病虫害防治及抚育管理为主的防治对策。
The cause factors of die-back disease in Eucalyptus sprout forest in Hezhou were analyzed by field surveys, and nutrient diagnosis methods to soil mineral and leaves, and the control methods for die-back in Eucalyptus sprout forest in Hezhou, Guangxi also carried out. The results showed that the main causes of die-back disease in Eucalyptus sprout forest were deficiency and other inappropriate management measures. Some countermeasures e. g. strengthen the fertilizer management, pest control and tending management for controlling this disease were also put forward.
