摘要
通过试验研究施肥种类、施肥数量、施肥方法对桉树红叶枯梢病防治效果的影响差异,结果表明,施用不同数量硼及不同施肥方法对桉树红叶枯梢病防治效果的影响差异显著;以150 g磷酸二铵+硼15 g(A3)+放射沟施(B3)组合最好,平均红叶转绿率达98.2%,平均抽高达到103.4 cm。
The difference of influence of red leaf dieback on Eucalyptus spp. were analyzed by studying fertilizer type, application rate and fertilization method. The result indicates that applying different amount of Boron （B） and different fertilization methods have significant effect on controlling effect of red leaf dieback on Eucalyptus spp. ;the combination of 150 g Diammonium Phosphate ＋ 15 g B （A3 ） ＋ open emission furrow fertilization（ B3 ） get the optimal effect; the mean ratio of transforming red leaf into green leaf reaches 98.2% ,and the mean height sprouting can reach 103.4 cm.
