摘　　要：为研究云锦杜鹃Rhododendron fortunei在粤北高海拔山区的栽培技术,观察记录了云锦杜鹃在不同抚育模式、不同山势环境的林木保存率和生长差异。结果表明:云锦杜鹃在连续每年割灌除草和施肥2次的抚育模式中的生长表现最优,并在造林第4年实现首次开花;生长在山坳的云锦杜鹃的生长量指标、林木保存率优于生长在山脊的云锦杜鹃,感染病虫害率较低;但是,在开花苗木占比、花芽数量和结果量等指标低于生长在山脊的云锦杜鹃,首次开花时间也晚于生长在山脊的云锦杜鹃。The cultivation experiment was carried out with Rhododendron fortunei.Seedlings in different forest tending modes and different locations of forest at high altitude mountain areas in northern Guangdong,and the conservation rate and growth performance of R.fortunei were observed.The results showed that the growth performance of R.fortunei was the best in the forest tending mode of cutting,weeding,and fertilizing twice a year,and the first flowering was achieved in the 4th year of afforestation.The growth index,conservation rate and health degree of R.fortunei on the col were better than those on the ridge.But the proportion of flowering seedlings,the number of flower buds and the fruiting quantity of R.fortunei on the col were lower than those on the ridge,and the first flowering year was also later than those on the ridge.
