      从北京市园林绿化树种选择中存在的主要问题、苗木市场形势分析、问题导向等方面，分析了苗圃发展的趋势。要解决城市街道绿化中品种混种、雌雄参杂、飞毛、落果、萌芽晚、落叶早现象，在绿化美化同时达到“延绿”的目的，提升景观效果，建设规模化苗圃应打造专业化的技术团队，打造特色化的品牌苗圃，注重良种选优工作。

英文摘要:

      The developing trend of nurseries was analyzed from three aspects: the main problems existing in the choice of tree species in Beijing, the analysis of market situation, and problem-orientated aspect. This study aims to solve problems of urban afforestation: mixed species, male and female mixed,catkins flying, fruit dropping, late sprout, early deciduous phenomenon. Meanwhile, the purpose of "green extension" to enhance the landscape effect is also considerable. To build large-scale nurseries，we should create professional technical team, orchestrate characteristics of the nursery brand, and focus on seed selection work.
