Study on the Prospect of Popularizing North American Oak Container Seedlings on“Four Modernizations”forestry construction in Shanghai

上海市统筹推进绿化、彩化、珍贵化、效益化,为四季增添丰富色彩,为林业建设提供新方向。北美栎树已应用于上海市林业建设中的林荫树、行道树和水源涵养林等,具树形优美,色叶变化明显,有耐水湿等优良特性,采用北美栎树容器苗可在造林时防止苗木根系受损,提高苗木存活率,增强抗逆性。本文从北美栎树容器苗发展现状及推广情况进行综述,分析了其在上海绿化"四化"建设中的推广前景。

Shanghai has made overall plans to promote afforestation,colorization,preciousness and efficiency,which increases rich colors in four seasons and provides a new direction for forestry construction.The north American oak has been applied in the forest construction in Shanghai as shade trees,street trees and water conservation forests,etc..The north American oak is with nice-looking tree shape,obvious change of leaf color in different seasons,and strong resistiblity of water and moisture.The use of container seedlings of north American oak can prevent the damage of seedling root in afforestation,improve the survival rate of seedlings,and enhance the resistiblity of the plants.In this paper,the situation of the development and popularization of the container seedlings of the north American oak were reviewed,and the prospects of its popularization in the construction of the"four modemizations"forestry in Shanghai were analyzed.
