池杉(Taxodium ascendens Brongn.)原产北美,从本世纪初开始引入我国,现巳在长江南北许多省市广为栽培,为南方平原水网地区的主要造林树种。池杉种子播后发芽迟缓,出土参差不齐,给育苗管理工作带来一定困难,而且产苗量低。研究其萌发生理特性和相应的催芽技术措施,在理论和生产实践上都有重要的意义。我们自1978年以来,就不断研究这项技术,以求达到池杉在育苗生产上“早苗、全苗、壮苗”的要求。现将研究结果介绍如下。
Taxodium ascendens Brongn. Originated in North America, introduced into our country since the beginning of this century, it has been widely cultivated in many provinces in the north and south of the Yangtze River and is the main afforestation tree species in the southern plain water network. Lack of seed germination lag slow, unearthed uneven, to nursery management has brought some difficulties, but the production of low seedlings. Studying its physiological characteristics of germination and the corresponding germination techniques have important meanings in theory and production practice. We have been researching this technology since 1978, in order to achieve the requirement of “saplings, full seedlings and strong seedlings” in the production of seedlings. Now the research results are as follows.
