'泓森槐'幼苗生理生态特性对模拟氮沉降的响应研究
Study on the Adaptability of Simulated Nitrogen Deposition to Robinia pseudoacacia'Hongsen'Seedlings
[目的]城市大气氮沉降与植物的响应及共存机制在一定程度上反映出城市植物提供生态系统服务的能力。'泓森槐'刺槐良种是适于城市园林绿化的新品种,具有的无刺、速生、抗性强等特征,探究其应对氮沉降的生理生态特征变化具有一定的现实意义。[方法]通过模拟氮沉降控制试验,以NH4NO3作为氮源,'泓森槐'作为氮添加对象,设置了低氮(LN,5 g·m-2·a-1)、中氮(MN,10 g·m-2·a-1)和高氮(HN,15 g·m-2·a-1)3 个模拟氮沉降水平…查看全部>>
[Objective]The response and coexistence mechanism of urban atmospheric nitrogen deposition and plants reflect the ability of urban plants to provide ecosystem services to a certain extent.The good species of Robinia pseudoacacia'Hongsen'is a new variety suitable for urban landscaping,with the characteristics of thornless,fast-growing,and strong resistance,and it is of certain practical significance to explore the physiological and ecological characteristics …查看全部>>
