紫玉兰(Magnolia liliflora)的花可提制芳香浸膏,花蕾能入药,是木兰科中各贵的观赏树种和药用植物,也是重要的香料植物。但由于该树种结实极少,扦插成活率又低,所以过去多采用分株或压条繁殖,数量较少,影响了紫玉兰的推广利用。为加速繁殖,我们从1983-1984年进行了扦插试验。一、试验地的选择插床设置在植物园背风向阳,地势平坦,排水良好的大荫棚(高3米) 下,选择一条长18米,宽1.2米,高20厘米的插床。床四周围 Magnolia liliflora flowers can be made of aromatic extract, the flower buds can be medicine, is Magnoliaceae in the expensive ornamental species and medicinal plants, but also important spices plants. However, due to the very few tree species, cutting survival rate is low, so in the past the use of ramets or battens multiply, the smaller the number, affecting the promotion and utilization of magnolia. To speed up the breeding, we conducted cutting experiments from 1983 to 1984. First, the choice of test site Slot set in the Botanic Gardens leeward sunny, flat, well drained large shade (3 meters high), select a 18 meters long, 1.2 meters wide, 20 cm high slot. Around the bed
