一、概况:桉树叶作为一种新型的桉叶扦插植物已得到广泛应用。尾叶桉树,又称Ugali(Eucalyptus),目前主要有两个桉叶扦插品种:
    
     (1) Silverdollar: large leaves, silver-gray leaf surface, strong fragrance, larger seeds, usually 180 grains per gram, seeds are sown at 22 C for 25 days.
    
     (2) silver dots (Silverdrop): small leaves, less fragrant, smaller seeds, 320 grains / gram.The optimum growth temperature of Eucalyptus leaves is from 15 to 30 C.In Kunming area, the growth is vigorous in spring and autumn, and the quality of leaf cutting is better. In summer, there are more rain on the leaves, which affects the quality of leaf cutting.Cut-leaf Eucalyptus grows vigorously, so its cultivation and management are extensive. 它通常种植在鲜切花基地的角落,或在保护篱笆的边缘。当它达到一定高度(1米到1.5米)时,可以用修剪法正常地切割。
    
     1。当尾叶桉幼苗在地面以上1.5米以上时,应从地面以上1.5米高度采摘,以促进侧枝的发育,以避免过度生长和切叶困难。
    
     2。树木修剪后,干桉侧枝生长较快。此时,树木修剪可以与树叶修剪相结合,具体方法是剪掉桉树叶,稀疏太多的枝叶,使剩下的枝条均匀分布在各个枝条上,从下到上呈三维分布,枝条不阻塞eac。其他的。通过多次修剪,培育整棵树,形成高度约1.5米至2米的树冠,树冠直径约为1米至1.5米,从而为未来的叶割高产打下坚实的基础。
    
     三。cutting leaves will enter the normal leaf cutting stage after the end of plastic surgery (about two years).At this time, only the newly growing leaves need to be continuously harvested and utilized, and attention should be paid to retaining certain old leaves and smaller branches in each leaf cutting to promote the growth of new leaves, while cutting leaves, attention should be paid to keeping the original tree type from being destroyed.
    
     4。桉树的水肥管理在生长上更为稳健,但作为一种特殊的桉叶扦插,为了达到多发芽、多产叶的目的,仍需进行适当的水肥管理。在每一个桉树上施用,并在旱季灌溉。
    
     5。病虫害防治桉树因其风味独特,害虫较少,无法专项防治。叶子感染影响装饰。在雨天可以喷洒百菌清等农药以防治。及时清除植物中的杂草,改善通风条件,促进植物健康生长。
