采用不同基质、不同生长促进剂以及不同处理方式,研究武夷四照花的扦插技术。结果表明:(1)1年生枝条的扦插生根率明显高于多年生枝条的生根率,可提高40%~50%;(2)8种扦插基质中蛭石效果最好,其次是黄沙;(3)不同生根促进剂对武夷四照花的扦插生根率影响差异显著,最佳处理组合为ABT生根液,浓度100mg·L-1,处理时间30 min,扦插生根率可达85%以上。
Different substrates, different growth promoters and different treatment methods were used to study the cutting techniques of Wuyi Si Zhao Hua. The results showed that: (1) The rooting rate of 1-year-old shoots was significantly higher than that of perennial shoots, which increased by 40% ~ 50%; (2) Vermiculite was the best among 8 kinds of cuttings, followed by yellow sand; 3) Different rooting accelerant had significant difference in cutting rooting rate of Wuyi Sihua. The best treatment combination was ABT rooting solution with the concentration of 100 mg · L-1 and the treatment time of 30 min, the rooting rate of cuttings could reach over 85%.
