腐植酸营养制剂在树木移栽、养护上的应用

The Application of Humic Acid Nutrition Agent in the Tree Transplanting and Conservation

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。

Abstract： In this paper, the commonly greening tree species were selected to study the effect of humic acid nutrition agent on the tree transplanting and conservation in different area. The results showed that, the length and quantity of new branches were both significantly increased compared with control when using the tree survival growth agent in transplanting, and the root growth was promoted. After the application of washing fertilizer in tree conservation, the quantity of new branches and the content of leaf chlorophyll were both higher than the control. When the two fertilizer composition using in old trees rejuvenation, the old trees growth were significantly improved. On the basis of the re- suits, the application mode of humic acid nutrition agent were proposed in tree transplanting, conservation and old tree rejuvenation.
