银川地区北京栾引种栽培与景观应用研究

Introduction and Cultivation of Beijing Goldenrain Tree for Yinchuan Region and Its Application in Landscape

将北京栾树引进银川地区进行圃地栽培,分析北京栾栽培适应性,不同栽植密度和施肥量对北京栾苗木生长的影响,不同栽植环境和配置方式对北京栾景观效果的影响。结果表明:银川地区引种北京栾作为观赏树种栽培具有可行性;北京栾苗圃地栽培初植密度为1.5 m×2.0 m;胸径3 cm左右的北京栾苗木初次施肥量应控制在30 kg/667 m^2左右,5月份施肥量控制在30 kg/667 m^2左右,10月份生物有机肥和尿素混合肥施用量控制在300 kg/667 m^2左右。

The introduction and cultivation of Beijing goldenrain tree for Ningixia region was studied.In this paper,the cultivation of adaptability,the influences of different panting density and fertilizing amount on seedling growth as well as the impacts of various planting environment and planting mode on the landscape effects were analyzed in detail.The results indicate that it is feasible to introduce Beijing goldenrain tree as the ornamental tree.The initial planting spacing should be 1.5 m×2.0 m.The amount of fertilizer applied to seedlings with DBH of about 3 cm should be controlled strictly.The initial fertilizing amount should be around 30 kg/667 m^2,around 40 kg/667 m^2 in May and 300 kg/667 m^2 in October.
