| 为研究铁皮石斛(Dendrobium officinale) 在粤北高海拔地区的生长适应性，采用大棚栽培，观
测铁皮石斛生长发育各项指标。结果表明，铁皮石斛适应试验地气候，春天萌发的嫩芽生长期为3—8
月，5—7 月份为嫩芽茎节急速膨大阶段，6—8 月份为嫩芽茎节快速伸长阶段。瓶苗当年生茎最高长度达
25 cm，平均茎高度达16 cm，平均茎粗度达6 mm。 |

| Abstract: |
| Temperature and humidity of the experimental greenhouse were observed and seedling growth
and development of Dendrobium officinale were analyzed to estimate the growth adaptability of D. officinale
at high attitude in northern Guangdong. The results showed that D. officinale was adapted to the climate of the
experimental area and the shoots germinated into Spring and grew from March to August. The shoot expanded
rapidly on May to July, and extended rapidly for June to August. The year maximum length of the stem went to 25
cm and the average hight was 16 cm, the average diameter of the stem was 6 mm. |
