曾有文章介绍说,目前由国外引进的矮生一品红,在家庭条件下不宜采用嫩枝扦插繁殖。而笔者通过实践发现,这些一品红不仅非常适宜嫩枝扦插,甚至可以采用单芽(节)繁殖,效果非常好。笔者曾经由外地引进一批“彼得之星”一品红种苗,由于运输包装韵原因,种苗出现许多折损。很快,这些损伤的枝条发生严重脱水、萎蔫,情急之下,笔者顺手将这些折损的枝条(种苗)全部投入近旁的水池中,结果意想不到的事情发生了。这些折损并且出现萎蔫的枝条,不仅很快全部恢复正常,而且叶片鲜嫩如初。在随后的日子里,由于管理上一时疏忽,又一次造成许多种苗失水萎蔫。于是笔者如法炮制,再一次将这些失水种苗全部投放水中,结果屡试屡爽。由此笔者意识到,一品红也可以像其他花卉那样采用嫩枝来进行水插。因为笔者手中的这批一品红种茁正是采用花泥进行嫩枝扦插的。而且花泥本身就是一种无土介质,除了含满水分,并无其他杂质,这正是变相无土水插的成功范例。于是,笔者将这些折损的枝条重新用薄刀片进行裁截,截取的部位选定在叶节下面0.5厘米处,摘掉基部一片叶,其他叶片均保持完整。截取后,及时将插穗创面流出的白浆洗净,用牙签在吹塑纸板(文具商店有售)上扎出小洞,将插穗固定在板上,任其漂浮于水面,无需特殊管理,在生长旺季,约15～
There was an article said that at present imported dwarf poinsettia in the family conditions should not be used to shoot propagation. The author found through practice that these poinsettia is not only very suitable for softwood cutting, or even single bud (section) breeding, the effect is very good. The author once introduced a batch of “Peter Star ” poinsettia seedlings from the field, due to transport packaging rhyme, seedlings appear many losses. Soon, these damaged branches severely dehydrated, wilting, in desperation, I easily these damaged branches (seedlings) all into the next pool, the results of unexpected things happen. These wilting and wilting branches, not only returned to normal soon, and the leaves are fresh and fresh. In the ensuing days, due to the negligence of management, many seedlings were watered out again. So I follow suit, once again all of these dehydration seedlings put in the water, the results repeatedly tried repeatedly cool. From this I realized that poinsettias can also be used for water plugs like other flowers. Because of the batch of poinsettias in the hands of the author Zhuo Zhu is using cuttings for softwood cutting. And flower mud itself is a soilless medium, in addition to full of water, no other impurities, which is a successful example of disguised soilless plug. Thus, the author re-cut these broken branches cut with a thin blade, cut the selected site 0.5 cm below the leaf nodes, remove the base of a leaf, the other leaves are intact. Interception, cuttings in a timely manner to flow out of the white pulp wash, with a toothpick in the blow molding cardboard (stationery store for sale) on a small hole, the cuttings fixed on the board, let it float on the water, without special management, at Growing season, about 15 ~
