尾叶桉无性系“生长停滞症”与土壤微量元素的相关性研究

Study on the Relationship Between Trace Elements and Slow-growing Symptoms of Eucalyptus urophylla Clone

近年来,在广东地区出现了较大面积尾叶桉U6无性系"生长停滞"的现象,为了确定该病症是否与土壤缺乏微量元素有关,本研究采用标准分析方法对"生长停滞"普发区及健康样地的土样进行检测并与全国第二次土壤普查分级标准比较,发现尾叶桉U6无性系"生长停滞"可能与土壤缺乏微量元素有关。

Slow-growing symptoms of Eucalytpus urophylla clone have been observed in the past few years in Guangdong province.In order to determine whether this is caused due to lack of trace elements inside the soil,six soil samples were obtained from healthy and diseased plantations for analyse by using the standard method.The results indicated that the symptoms could be the result of lack of trace elements.
