以不同地区常用绿化树种为供试材料,进行了腐植酸营养制剂在树木移栽、养护和古树复壮上的应用效果研究。结果表明,在移栽中施用成活增长剂后,苗木的新梢长度、新生枝条数量较对照显著提高,根系的的生长也得到了促进;在养护中施用冲施肥后,苗木新生枝条数量和叶片叶绿素含量显著升高;二者复合使用进行古树复壮,古树的长势得到了明显的改善。以本研究结果为依据,提出了腐植酸营养制剂在树木移栽养护、古树复壮上的应用模式。
The common greening tree species in different regions were used as test materials to study the application effects of humic acid nutrient preparations on the transplanting and conservation of trees and rejuvenation of old trees. The results showed that the number of shoots and new shoots of seedlings increased significantly and the growth of root system was also promoted after transplanting. Compared with the control, the numbers of new shoots and leaves Chlorophyll content increased significantly; the two used in combination to rejuvenate the ancient trees, the growth of old trees has been significantly improved. Based on the results of this study, we put forward the application mode of humic acid nutrition preparations in the conservation of trees and rejuvenation of old trees.
