椋子木引种栽培初探

Study on Introduction and Cultivation of Cornus macrophylla Wall.

[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。

The aim of the study was to seek introduction and cultivation and avenues of exploitation and utilization of Comus macrophyUa Wall. [ Method] The biology and ecology characteristic of Comus macrophylla Wall. was observed, and the seed sprout characteristics, the growth regular of one-year and five-year nursery stock of Comus macrophylla Wall. were studied. [ Result ] The study showed that Comus 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 Its seed had the characteristics of deep dormancy,which could be rescinded effectively when the seeds were stored outdoor in low tenmpemture sand for 120d.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 mursery stock was 656 cm and its underground diameter was 7.78 cm. [ Conclusion] Comus macrophylla Wall. was a kind of native tree species which had.atrongly ecology adaptability and could grow rapidly in Henan Province,which should be planted largely.
