摘要
通过试验观察,对兜唇石斛的植物学特征进行了描述;对其生物学习性的观察看到,花期在3月中下旬至4月下旬,开花同时抽新芽、长新根4~8条;5-7月是伸长生长期,8-10月是茎增粗期,10-11月植株成熟,12月至翌年1月植株休眠;茎寿命4年,4年以后,茎黄化萎缩,失去药用价值;果期为5-12月,10-12月种子成熟;单花寿命9~11 d,开花后2~5 d内进行人工授粉可以获得较多的种质资源。
The botany features of Dendrobium aphyllum are described through investigation. Sprouting would happen with four or eight of new roots in mid-late March to the late of April while it is the right time in blossom. Then enter the elongation period from May to July. Stem becomes thicker from August to October. Plant matures between October and November. Plant would be dormancy from December to January of next year. The stem of this plant has only 4 years life,no medicinal value after yellowing and wilting. Ripe seeds would be obtained in October to December. The single flower has only 9 to 11 days life and more germplasm resources can be kept through hand pollination within 2 or 5 days after flowering.
