唐棣扦插生根技术研究

The Research on Amelanchier alnifolia Rooting Cuttings Technology

[目的]开展唐棣扦插生根技术研究,以期促进新疆经济林结构调整和可持续发展。[方法]研究了唐棣枝条木质化程度、ABT生根粉浓度、浸泡时间及两种生长调节剂等因素对唐棣扦插成活率的影响,并开展了不同基质对生根的影响试验。[结果]研究结果表明:唐棣扦插成活率两年生枝条明显高于一年生枝条;ABT生根粉浓度为75μg/g且浸泡4 h的处理对两年生插穗效果最好,成活率最高;在促进唐棣扦插成活率中,根宝3号比ABT效果更好;沙壤土更适合作为唐棣扦插育苗基质。[结论]总结出高效扦插育苗新技术,为唐棣扦插育苗提供参考和理论依据。

[ Objective ] Amelanchieralnifolia ＂rooting cuttings technology was studied for promoting the adjustment of Xinjiang economic forest structure and sustainable development. [ Method ] The effect of lignification degree of A. alnifolia branches, concentration of ABT, impregna- tion time and two growth regulating agents on A . alnifolia cutting survival rate, as well as the impact of different substrates on rooting have been studied in this paper. [ Result] The results showed that A. alnifolia cutting survival rate of biennial branch was significantly higher than annual branches. The treatment of 75 i^g/g ABT rooting powder, soaking 4 h worked best for biennial cuttings. The function for A. alnifolia cutting survival rate of Genbao the 3rd was better than ABT. Sandy loam soil was more suitable as matrix for A. alnifolia cuttage. [ Conclusion] New technology of efficient cutting seedlings has been summed for providing the reference and theoretical foundation for A. alnifolia cuttage.
