摘要: 目的】研究平欧杂种榛黄化萌条扦插的适宜环境及管理方式,为简化扦插环境及田间管理提供理论依据。【方法】采用方差分析、相关性分析等方法,将黄化萌条置于3个环境下扦插管理,分析比较萌条抽梢生长、根系生长及根系质量等指标的差异。【结果】在不同环境下,扦插生长根系指标存在差异性;3个环境条件下以塑料大棚(A)叶绿素含量及根系综合指标最佳,其次为榛子示范园行间(B),长山核桃大树行间(C)最低,说明扦插管理对根系生长影响较大。B环境因光照充足,综合根系指标高于C环境,但C环境抽梢生长及生根率指标较高,证明扦插中期土壤湿度增加可促进扦插生长,且土壤肥力同样影响根系生长力;此外,黄化萌条与嫩枝扦插相比较,管理复杂度降低50%,且生根速率、生根率、根系质量等均提高。【结论】生产中应以A环境扦插生长为参考,扦插管理前期严格控温控湿,后期逐步加大与外界环境的接触面,大幅度降低了黄化萌条的扦插管理复杂度。

Abstract: Objective】 To study etiolation coppice shoot cutting suitable environment and management of Corylus heterophylla Fisch ×Corylus avellana L. in the hope of providing theoretical basis for simplifying cutting environment and field management.【Method】In this study, variance analysis and correlation analysis were used to analyze the differences among the indexes such as shoot growth, root growth and root quality of the seedlings under 3 environments.【Result】There were differences in growth and root indexes in different environments; Under 3 environmental conditions, chlorophyll content and root system index were best in plastic greenhouse (A), followed by hazelnut demonstration garden (B), and pecan trees between rows (C) were lowest, which showed that cutting management mode had a great effect on root growth. Because of the sufficient illumination of B environment, the comprehensive root index was higher than that of C, but C environment had higher rooting rate and faster branch growth. This could be seen that the increase of soil moisture could promote the growth of cuttings in the medium stage soil moisture; in addition to that, soil fertility could also affect root growth. Furthermore, compared softwood cuttings with etiolation coppice shoot management complexity reduced 50%, and the root growth rate, rooting rate and root quality were improved.【Conclusion】The results preliminary responded to the importance of etiolation coppice shoot cutting environment and management model. In view of the future production work, we should take the whole artificial arch shed (A) as reference, strictly control the temperature and humidity in the early stages, and gradually increase the contact surface with the external environment, greatly reduce the management complexity of a yellow bud for the future cutting work in the late stage.

Key words: Corylus heterophylla Fisch. ×Corylus avellana L.; etiolation coppice shoot; cutting environment; management mode
