桂花为著名花木之一,叶终年常青,中秋开花,浓香四溢,花朵可供提炼香料、食用、药用等,经济价值很高。 桂花的繁殖各地均以靠接法为主,压条繁殖生根困难,很少采用。靠接的砧木一般用女贞(Ligustrum lucidum Ait.)、小叶女贞(L.quihoui Garr.),也有用小叶白腊(Fraxinusbungeana DC.,如河南省)的。但用女贞等作砧木时,在黄河以北无法露地越冬而小叶白腊根系较弱,稍受损伤就会造成死亡。同时采用靠接法必须带盆操作,手续繁琐,需时较长,因而济南王庄苗圃于1962年春开始用流苏树(本地称“牛筋子”)为砧木,以劈接方式进行桂花的繁殖试验。 流苏树(Chionanthus retusus Lindl.et Paxt.)属木犀科,系开花灌木。 此树原产河北、河南、山东、陕西、湖北、四川、云南、江西、浙江、福建、广东等地,播种繁殖,其抗旱、抗寒性都远远超过女贞或小叶白腊等,且生长势较强。我们于1962年用它作砧木嫁接桂花20株,成活10株(成活率50％)。1963年嫁接350株,由于嫁接人员均系新手,技术不熟练,管理又欠妥当,成活率仅达30％左右。1964年又接了3,000余株, Sweet-scented osmanthus is one of the most famous flowers and trees, with evergreen leaves, mid-autumn flowering, fragrant flowers, flowers for refining spices, edible, medicinal and so on, with high economic value. Sweet-scented osmanthus breeding all around the docking method based, batching breeding root, rarely used. Lying stock is commonly used with Ligustrum lucidum Ait., L.quihoui Garr., And Fraxinus bungeana DC., Such as Henan Province. However, with privet as the rootstock, north of the Yellow River can not be exposed to wintering and lobular white roots weak, slightly damaged will result in death. At the same time using the docking method must take the basin operation, tedious procedures, takes a long time, so Jinan Wang Zhuang nursery in the spring of 1962 with tassel tree (locally known as “beef tendon”) as the rootstock, cleavage approach Osmanthus breeding test . Flowery tree (Chionanthus retusus Lindl.et Paxt.) Is Oleaceae, Department of flowering shrubs. The tree native to Hebei, Henan, Shandong, Shaanxi, Hubei, Sichuan, Yunnan, Jiangxi, Zhejiang, Fujian, Guangdong and other places, sowing and breeding, its drought, cold resistance far exceeds the privet or lobular white and so on Strong growth potential. We use it as a rootstock in 1962 grafted osmanthus 20, 10 survived (survival rate of 50%). In 1963, 350 plants were grafted. Due to the grafting of new staff, unskilled technique and improper management, the survival rate was only about 30%. In 1964 and then received more than 3,000 strains,
