| 摘 要： | 通过多年的引种驯化和观测,发现‘十月梅’是目前北京地区冬季开花景观效果最好的蜡梅品种。对蜡梅开花过程中花蕾、花朵含水率和枝条含水率的变化趋势进行测定,结果表明北京地区影响蜡梅冬季开花的关键因素是水分和温度。通过土表覆盖,可以有效保湿,提高土温,保持枝条含水率,促进蜡梅在冬季提早开花且多开花。

| Abstract: | Based on domestication and observations for more than ten years,we find that,among diverse varieties and cultivars of Chimonanthus praecox,’Shiyue’ is the best winter-blooming cultivar in Beijing.Analyses of variations of moisture contents in buds,flowers and twigs during the blooming process showed that temperature and moisture are two key factors affecting the winter blooming.Trials of mulching in winter indicated that it could effectively raise the temperature of soil and keep the moisture content of twigs,consequently promoting ahead the blooming time and increasing flower abundance of C.praecox. |
