摘要
The experinent about the artificial cultivation of the wild Dendrobium flexicaule showed that indoor planting was better than planting in a shade-frame,and the surviving percentages were 82 7% and 80 3% respectively.Under indoor planting conditions,the surviving percentage was 79 8% from February to March and 81 2% from September to October.The Highest surviving percentage was 87 7% fertilized with 200g/m 2 seedcake.The land was irrigated better with water in a mountain or spring than that in a well or river,and the surviving percentages were 90 7%,85 3% and 82 5% respectinelty.The surviving percentage increased with the increase of altitude and shade density.Concrete techniques and measures for artificial cultivation were also introduced.
