青檀(Pteroceltis tatarinowii)扦插成活率低,是其优良无性系苗木繁育的主要障碍。为加快青檀优良无性系的繁殖速度,2012—2014年,对选育的青檀优良无性系TX01进行了嫁接育苗试验。结果表明,利用穴盘和混合基质播种繁育青檀砧木,出苗率达到90.1%,移栽后生长快,当年末平均苗高79.6cm,平均地面直径0.57cm,全部达到嫁接要求。采用蜡封接穗切腹接的方法嫁接青檀良种TX01,嫁接成活率达到92.8%,年末平均苗高230.5cm,平均地面直径1.46cm,砧穗亲和力高,嫁接口愈合良好,苗木生长健壮、整齐。育苗成本1.29元/株,效益比1∶3.64。
Pteroceltis tatarinowii cuttings survival rate is low, is the fine clones nurturing the main obstacles. In order to speed up the reproduction of fine sandalwood clones, from 2012 to 2014, the grafted seedlings of elite P. falcata TX01 were selected. The results showed that seedling and hybrid matrix sowing P. ebony rootstocks showed 90.1% emergence rate and rapid growth after transplanting. The average seedling height at the end of the year was 79.6cm with an average ground diameter of 0.57cm, all of which met the grafting requirements. The method of wax seal scion cut abdominal access grafted elite TX01, grafting survival rate reached 92.8%, the end of the average seedling height 230.5cm, the average ground diameter of 1.46cm, anvil ear high affinity, good healing graft, seedlings grow robust and tidy. Nursery costs 1.29 yuan / plant, the profit ratio of 1: 3.64.
