【摘要】 [目的]探讨椋子木引种栽培技术及开发利用途径。[方法]对椋子木的生物学及生态学特性进行了观察,并对椋子木种子的萌发特性、1年生苗木及5年生苗木的生长规律进行了研究。[结果]椋子木耐寒、耐旱、抗高温、耐盐碱和瘠薄;椋子木种子具有深休眠特性,室外低温沙藏至少应在120 d以上,可有效解除其休眠状态,促进种子萌发;椋子木1年生苗高达161 cm,地径达1.1 cm;5年生苗木高达656 cm,地径达7.78 cm。[结论]椋子木是一种生态适应性很强的乡土树种,在河南郑州地区表现出良好的速生特性,可以进行推广种植。更多还原

【Abstract】 [Objective] The aim of the study was to seek introduction and cultivation and avenues of exploitation and utilization of Cornus macrophylla Wall.[Method] The biology and ecology characteristic of Cornus macrophylla Wall.was observed,and the seed sprout characteristics,the growth regular of one-year and five-year nursery stock of Cornus macrophylla Wall.were studied.[Result] The study showed that Cornus macrophylla Wall.could endure cold,drought,high temperature,saline-alkali and barren soil.Its seed had the characteristics of deep dormancy,which could be rescinded effectively when the seeds were stored outdoor in low temperature sand for 120d.The height of one-year seedling was 161 cm and its underground diameter was 1.1 cm,the height of five-year nursery stock was 656 cm and its underground diameter was 7.78 cm.[Conclusion] Cornus macrophylla Wall.was a kind of native tree species which had strongly ecology adaptability and could grow rapidly in Henan Province,which should be planted largely.更多还原
