五种类型树木前景广阔
Five types of trees have broad prospects
今年东北绿化随着工程量的增加，对苗木有很大需求，其中，我认为五个品种前景最广阔。一是乡土树种东北地区很多乡土树种因生长慢、繁殖难，常都被忽视而一些城市建设部门盲目引进外来树种，更是走入了绿化误区。如今，很多人开始将目光转向乡土树种，如大叶朴、小叶朴、辽东栎、蒙古栎以及一些槭树科乡土品种，这些树种适应性强，将在绿化中唱主角。
With the increase of engineering quantity, there is a great demand for seedlings in Northeast greening this year. Among them, I think five varieties have the widest prospect. First, native tree species. Many native tree species in Northeast China are often ignored because of slow growth and difficult reproduction. However, some urban construction departments blindly introduce foreign tree species, which leads to the misunderstanding of greening. Nowadays, many people begin to turn their attention to native tree species, such as magnolia, Magnolia, Quercus liaotungensis, Quercus mongolica and some Aceraceae native species, which have strong adaptability and will play a leading role in greening.
二是观花小灌木以及观果苗木。城市要真正靓丽起来，少不了应用有花的植物来进行点缀，像山桃、山杏山梨、山楂等观花时间长的小乔木在绿化市场上不可或缺。而一些观果的乔木品种如忍冬等如能进行适当应用绿化效果则更丰富。
The second is small shrubs and fruit seedlings. If a city wants to be really beautiful, it is necessary to use flowering plants to decorate it. Small trees with long viewing time, such as peaches, apricots, pears and hawthorn, are indispensable in the green market. Some ornamental tree species, such as Lonicera japonica, are more effective if they can be used properly.
三是色叶树，金叶白蜡春季叶片金黄，夏季变成黄绿，秋季落叶期呈金黄色，整个生长季叶片颜色艳丽。在城市的休闲公园中应用前景广阔。
The third is the color leaf tree. The leaves of Fraxinus chrysanthus are golden in spring, yellow green in summer and golden yellow in autumn. It has a broad application prospect in urban leisure parks.
四是耐阴树种，如今城市高楼林立，城市急需耐阴树种，如荚蒾、辽东卫矛等。
The fourth is shade tolerant tree species. Nowadays, there are many tall buildings in the city, and the city urgently needs shade tolerant tree species, such as Podocarpus, Euonymus liaotungensis, etc.
五是珍贵树种，如东北红豆杉、银杏、华山松等，这些树种大多价格高、生长慢，但观赏价值高，在城市公园中起点缀作用。城市中以乡土树种为主打，引进三至四种外来珍贵品种更能彰显绿化水准。
The fifth is precious tree species, such as Taxus cuspidata, Ginkgo biloba, Pinus armandii and so on. Most of these tree species have high price, slow growth, but high ornamental value, and play an important role in urban parks. The introduction of three or four kinds of exotic precious species can highlight the greening level.
