赤楠在城市不同生境的种植适应性试验

Experiment on Adaptability of Syzygium buxifolium at Various Habitats in City

采用对比试验的方法,在城区不同生境将赤楠(Syzygium buifolium)1年生籽播容器苗作地被植物应用种植试验,结果表明:①赤楠容器苗在城区不同生境种植,成活率均在98%以上,且均能安全越夏,无日灼;②赤楠在空旷露地种植会发生寒害,寒害指数为2.20,在四周有建筑物或有上层植物遮挡的生境种植寒害明显减轻,在强郁闭林下无寒害;③在中等郁闭的公园绿地种植生长最快,种植1a后赤楠苗高达到40.48cm,冠幅达30.26cm,明显大于其它类型立地。

Contrast experiment was made on adaptability of Syzygium buxifolium under different habitats at urban area with 1-year container seedlings as ground cover. The result showed that survival rate of seedlings planted at different urban habitats was more than 98% and tested seedlings could over-summer without sunburn. Cold damage occurred to seedling planted in open field with index of 2.20, but it decreased when seedling planted around buildings or under plants. Seedlings planted under middle closed forest in park had the fastest growth. One year later, the height growth of S. buifolium seedlings topped 40.48 cm, canopy diameter was 30.26 cm, significantly larger than that under the other habitats.
