摘要
选取功能叶好的嫩枝,剪取约20 cm的插穗,长节位的留2节就可以,保留全叶或剪去每个叶片的1/3叶即可,扦插深度为最下面节位与基质接触即可,节位短的插穗要插下土1/3的长度,每个花盆扦插2~3个插穗,用手压紧插穗周围的基质,浇足水,再用白色塑料袋罩住花盆,放置在遮荫率75%处,投入成本低,景观效果好,具有很好的发展前景,可供热带地区推广反季节珊瑚藤快繁技术提供参考。
Young shoots with good functional leaves were selected from the plants of coral vine（Antigonon leptopus） and cut into sections about 20 cm long as cuttings, two nodes enough for the long node vine.All the leaves in the cuttings were kept or one third of each leaf was cut off in the cuttings.The cuttings were planted to the depth when the bottom node touched the cutting substrate or to the depth of one third of the short-node cuttings.Two or three cuttings were planted in a flower pot.The substrate in the pot was compacted by hand around the cuttings and watered well.The pot was then covered with white plastic bag and placed under the shelter with 75% shade.Coral vine cutting propagation is low in input, and has a good ornamental effect and hence a good prospects for development.It provides reference to promote rapid propagation technology for coral vines in the off-season in the tropical areas.
