摘　　要：为了有效利用扦插技术生产优质栝楼种苗和控制合适的雌雄株比例,比较研究了ABT不同浓度(0、50、100和200mg/L)、100mg/L浓度时不同浸泡时间(10、20、40和60min)、不同插穗长度(1节、2节和3节)对插穗生根率和扦插苗移栽成活率的影响,结果表明:用珍珠岩做基质时,选用当年生2节插穗,用100mg/L浓度ABT粉浸泡40min效果最好,插穗具有100%的生根率,种苗具有99%的移栽成活率。In order to effectively utilize cutting technology for producing high-quality Trichosanthes seedlings and controlling an appropriate proportion of male and female plants, the study examined the effects of different ABT concentration （0 mg/L, 50 mg/L, 100 mg/L and 200 mg/L）, different soaking time under 100 mg/L ABT（10 min, 20 min, 40 min and 60 min） and different cuttings length （1 node, 2 nodes and 3 nodes） on cuttings rooting rates and transplant surviving rate. The results show that： When using perlite as matrix, the optimum condition of cuttings propagation is selecting one-year branchs with 2 nodes as cuttings and soaking them with 100 mg/L ABT for 40 minutes, under which, the 100% rooting rates of cuttings and 99% transplant surviving rate of seedlings were obtained.
