摘　　要：连续两年的研究结果表明，只要采取合适的覆盖措施在南京地区寒冬季节移植香根草是可行的。在所有供试处理中。覆膜措施效果最好，不但可以保证冬季种植的香根草春季返青成活率高于80％，春季返青时间比同期其它措施提前1～11d，而且防寒效果相对稳定，其它措施的防寒效果会随着移栽季节的不同而发生变化。研究还显示：南京地区大约12月中下旬至次年1月低温期间采用覆膜措施才能呈现出它的优势。在冬季最冷季节内移栽香根草时，覆膜措施与其它覆盖处理存在显著差异，而其它时段采用覆膜措施尽管防寒效果也相对较好。但与其它处理之间没有显著差异。The results of two successive years research proved that if proper measures were adopted Vetiveria zizanioides can be successfully transplanted in cold winter in Nanjing region. In all given treatments, the effect of covering membrane measure was the best, which not only ensure that the survival percentage of transplanted V. zizanioides in next spring was beyond 80 % and the returning green time in the spring can advance about 1-11d than ones of other treatments with the same transplanting time, but also chillproof effect was comparatively stable. However, the chill-proof effects of other measures changed irregularly, which changed with transplanting time. Meanwhile, the research also showed that only in the duration from late half Dec. to late Jan. of next year covering film measure was adopted can the advantage arise. When V. zizanioides is transplanted in the coldest period of a year there were significant differences between covering membrane measure and other measures. Although the effect of covering membrane measure also is preferable if V. zizanioides was transplanted in the other period, it showed no significant differenees with other treatments.
