摘要
根据多点造林3~4年的观测结果,通过生长、耐涝性、抗风性、抗病虫害和景观指数等指标,对从美国引进的20个耐水湿树种和种源进行综合评价。以耐涝、抗病虫和景观价值为主要评选目标。结果表明:以水紫树、黑栎、沼地紫树、苏玛栎、纳塔栎、落羽杉、美国枫香和美国梧桐的综合表现为优,北美鹅掌楸、复叶槭、河桦表现较差。引种试验结果为长江中下游平原地区生态和景观建设提供了优良的树种资源。
Twenty two tree species were introduced from USA to the wet-land plain of Yangtze delta region in 2003.The experiments had been conducted in Fuyang of Zhejiang province,Songjiang of Shanghai city and Jiangdu of Jiangsu province.The tree species were evaluated based on their growth,waterlog-enduring,wind-breaking,ornamental values and disease and pest resistance in the past 3 years.According to the values of landscape and resistance,Nyssa aquatica,Liquidambar styraciflua,Taxodium distichum,Platanus occidentalis,Quercus nigra,Q.phellos,Q.nuttallii and Q.shumardii were proven to be suitable for the Yangtze Delta Region,and the adaptation of Liriondendron tulipifera,Acer negundo and Betula nigra were limited and poor.The testing results provied a base for tree species selection in the Yangtze Delta Region.
