大围山樱属植物资源调查

Investigation of Cerasus resources on Dawei Mountain

为了解大围山樱属植物种质资源分布和、生物学特征和观赏价值,2017~2019年采用普查、重点调查与样地调查相结合的方法对大围山的樱属植物资源进行了调查。结果表明:大围山樱属植物资源从低海拔至高海拔依次分布有钟花樱、尾叶樱、华中樱和雪落樱4种;开花时间顺序是从低海拔逐渐向高海拔开放,钟华樱的盛花期在2月底至3月上旬,尾叶樱在3月中下旬,花中樱在3月下旬至4月上旬,雪落樱为4月中旬;4种樱花资源均具有良好的开发利用价值。

For studying the distribution, biological characteristics and ornamental value of Cerasus resources in Dawei Mountain, a survey was carried out in 2017-2019 by means of general survey, key survey and sample plot survey. The results show that Cerasus resources in Dawei Mountain are distributed from low to high altitudes in turn, which contain 4 types including Cerasus campanulata, Cerasus dielsiana, Cerasus conradinae and Cerasus xueluoensis. The order of flowering time ranges from low elevation to high elevation. The flowering period of Prunus campanulata is from the end of February to the first ten days of March, that of C.dielsiana is in the middle and last ten days of March, that of C.conradinae is in the last ten days of March or the first ten days of April, and that of C. xueluoensis is in the middle of April. All four Cerasus species have good development and utilization value.
