摘　　要：为提高北方温室火龙果扦插生产技术,本文选取台湾大红火龙果的枝条为试验材料,从扦插基质和插穗类型两方面进行插穗成活率的比较试验,通过对比火龙果不同插条和扦插基质的生根水平,筛选出最适合寒地火龙果扦插生根的方法。结果表明:两年生与三年生侧枝作为插穗成活率高于一年生侧枝插穗,15~20 cm长的插穗能为生根提供充分营养供给,扦插基质草炭∶蛭石∶细沙体积比为2∶1∶1,并加入1/20体积的生根粉或生物菌剂,可保证成活率高于80%。In order to improve cutting production technology of pitaya in northern greenhouse,in this paper,the cuttings survival rate of Taiwan Red Pitaya was compared from two aspects of cutting medium and cutting type.By comparing the rooting levels of different cuttings and cutting media,the most suitable rooting method of pitaya in cold region was screened out.The results showed that,the survival rate of two-year-old and three-year-old lateral branches was higher than that of one-year-old cuttings.The cuttings with the length of 15-20 cm could provide sufficient nutrition for rooting.The cutting medium was peat∶vermiculite∶sand volume ratio of 2∶1∶1,and adding 1/20 volume of rooting agent or biological agent,the survival rate was higher than 80%.
