摘要
本文通过野外调查和定位栽植对比试验，对吴柏的生长发育和更新进行研究结果表明：臭柏枝条新梢于４月中旬开始生长，７、８月间生长最快，１０月上旬停止生长。臭柏有性繁殖较困难，其自然繁殖过程是枝条沙埋后萌发不定根而形成新的个体来繁衍扩大灌丛，其枝条上有根原始体是潜在的生根机制，每年新形成的根原始体９０％出现在３令枝上，２令和４令枝上仅占１０％；所以３到７年生幼枝生根能力较强。
This paper has researched the growing,development and regeneration ofSabina Vulgaris Aut.through comparig between field investigation and located plantation.The results show that the new tips of branches of Sabina Vulgaris Aut.Start to grow in midaprii and go up to their quickest growing between July and August’it stop growing at the be-ginning of Octoker;It is difficuIt to undergo its sexual multiplication, the natural reproduct-ing proces;is that the branches were covered by somel and sprowt adventibious root and form a new individual.So the shrwb of Sabina Vulgaris is enlarged and reproducted;The primibive bodies of roots in the branches are the Potential rooting mechenism.90 percent of newly-grown primitive bodles of roots or the three-year branches and only 10 percent on the two-year and four branches and only 10 percent on the two-year branches per year.So the branches of three years to seven years have stronger ability of growing roots.
