为丰富南亚热带树种种质资源圃棕榈科植物物种资源,发挥棕榈科在城市行道绿化与生态园林绿化建设中的作用,1998年引进了布迪椰子种子,以此为材料,进行了播种育苗试验、苗木施肥试验、光照对苗期生长影响的试验、生长情况、物候及适应性观测。结果表明,该树种能适应南宁砖红壤性土壤,在南亚热带气候条件下能正常生长,小苗不用采取任何防寒措施,能安然度过-1.9℃低温,10年来未发现病虫害,具有较好的生态适应性,已开始开花结实。由于该树种具有比较鲜艳的花序,花序梗及花瓣均为紫红色,加之银灰色叶片在阳光下显得银光熠熠,因而极具观赏价值,同时十分耐寒耐旱,因此可作为南棕北引的一个首选品种,具有很高的推广价值与市场应用前景。
In order to enrich species resources of palm tree plants in South Asia tropical tree germplasm resources and to play the role of palmaceae in urban road greening and ecological landscaping construction, in 1998 Burdee coconut seeds were introduced and used as materials to carry out sowing and nursery trials , Seedling fertilization test, light on the growth of seedling growth test, growth, phenological and adaptive observation. The results showed that the tree species could adapt to the soil of Nanning brick red soil and could grow normally in the subtropical climate. The seedlings did not take any cold measures, which could safely survive the low temperature of -1.9 ℃ and had no pests and diseases in 10 years, and had a good ecology Adaptability has begun to flowering and fruiting. As the species has a relatively bright inflorescence, peduncles and petals are purple, combined with silver-gray leaves appear in the sun silver shiny, so very ornamental value, is also very cold and drought, it can be cited as the North South Brown A preferred species, with high promotional value and market prospects.
