摘要
在分析落叶松种子园花芽分化规律、开花授粉机理以及雌球花自交败育原因基础上,根据实践经验总结提出了落叶松种子园促进结实的技术方法,包括科学水肥管理、树体管理、赤霉素处理和人工辅助授粉等,可为条件相同或相近地区落叶松种子园提供参考。
Through the analysis of flower bud differentiation rules,flowering and pollination mechanism and the causes of female cone self-abortion in Larix kaempferi seed orchard,the technical methods of promoting seed setting were summarized.Watering and fertilization management,tree management,Gibberellin treatment and artificial pollination combined would help to achieve high quality and high yield in Larix kaempferi seed orchard.
