珍稀濒危树种云南蓝果树育苗技术研究

A Study of Seedling Cultivation Techniques of Nyssa yunnanensis

  • 摘要: 对云南蓝果树的种子采集处理、育苗试验和对苗木生长观测调查,初步研究了云南蓝果树的育苗技术、苗期生长规律。结果表明:云南蓝果树种子无休眼期,宜随采随播,播种1周后开始萌动,25 d出土,种子贮藏方式以混沙贮藏为好。培育的云南蓝果树容器苗210 d即可出圃造林,1 a生苗高和地径的生长节律呈现出"慢-快-慢"的生长过程,其幼苗的生长高峰为6月~7月,这期间应加强水肥管理,促进苗木生长。

     

    Abstract: Studies were made of the seedling cultivation techniques of Nyssa yunnanensis and the growth characteristics of this species during the seedling period, including researches on seed collection, seed treatment, seedling raising, and growth observation during the seedling stage. The results showed that the seed of Nyssa yunnanensis did not have dormancy stage, the seeding work was suitable to be done right after the collection of seeds. The seeds began germinating one week after seeding, the seedling emergence occurred 25 days after seeding, and the proper way of storing seeds was to be mixed with sand. The seven month old seedlings could attain the size suitable for field planting, within one year after seeding, the seedlings showed the growth process of ‘slowness-quickness-slowness’, the growth peak of the seedling occurred from June to July, and within this fast-growing period, sufficient water and fertilizer should be applied to promote the growth of the seedlings.
