扦插是繁殖花木的一种良好方法,但较难生根的花木往往成活率较低。如果用高浓度的生长调节剂快速浸泡接穗,则效果较好,特别是含笑、茶花、杜鹃、猕猴桃、桂花、罗汉松、柏等木本植物。具体做法是:先将萘乙酸或吲哚丁酸配成1000—3000PPm的溶液,将剪好的硬枝插穗浸入配好的溶液中(深度为插穗的1/3)3-5秒钟,然后插入基质中,淋足水。而半木质化的插穗宜用较低的浓度 Cutting is a good way to breed flowers and trees, but the flowers and trees that are more difficult to root often have lower survival rate. If high concentrations of growth regulators soaked scion, the effect is better, especially with smiling, camellia, rhododendron, kiwi, osmanthus, Podocarpus, cypress and other woody plants. The specific approach is: first NAA or indole butyric acid dubbed 1000-3000PPm solution, the cut hardwood cuttings immersed in a good solution (depth of cuttings 1/3) 3-5 seconds, and then Insert into the matrix, pour enough water. The half-lignified cuttings should be used at lower concentrations
