绿化苗木主要分为行道树、花灌木、绿篱、草本花卉、草坪等几大类。实际的绿化中都会采用二到三种以上来进行全部的绿化。
Greening seedlings are mainly divided into several categories, including street trees, flower shrubs, hedges, herbaceous flowers, and lawns. In actual greening, two to three or more types will be used for all greening.
以公园为例，道路两旁会植以玉兰、银杏、黄金槐、红枫、香樟等乔木作为行道树，可观赏、可遮荫。行道树底下会植以、红叶石楠、金叶女贞、小叶黄杨等绿篱类苗木，用以把道路和花坛隔离开来。花坛内可以种植各种花灌木，比如梅花、樱花、丛生紫荆等观花灌木，用以赏花之用。花坛里剩余的地被，则可以用红花草、鸢尾、葱兰等观花草本花卉覆盖，也可以植以麦冬草、四季草等草坪。
Taking the park as an example, trees such as magnolia, ginkgo, yellow locust, red maple, and camphor will be planted on both sides of the road as roadside trees for viewing and shading. Under the roadside trees, hedge seedlings such as red leaf heather, golden leaf privet, and small leaf boxwood are planted to isolate the road and flower beds. Various flowering shrubs can be planted in the flower bed, such as plum blossoms, cherry blossoms, cluster redbuds, and other ornamental shrubs, for the purpose of appreciating flowers. The remaining ground cover in the flower bed can be covered with ornamental plants such as saffron, iris, and scallion, as well as lawns such as winter wheat grass and four season grass.
2.根据观赏目的来选用
2. Choose according to the viewing purpose
比较常见的樱花园、梅园、紫藤长廊等，以单一品种为主题制作的观赏性园林，在苗木的选择上则以主体苗木为主，搭配其它苗木。比如樱花可以配植桃花，在樱花凋落时桃花正好盛开。
Common ornamental gardens such as cherry blossom gardens, plum gardens, and wisteria corridors are designed with a single variety as the theme. The selection of seedlings is mainly based on the main seedlings, paired with other seedlings. For example, cherry blossoms can be paired with peach blossoms, which happen to bloom when they wither.
3.观花类苗木根据开花季节来选用
3. Selecting flowering seedlings according to the flowering season
还是以公园景观为例，园林一般要求一年四季都要具有观赏性，因此在苗木的选择上面会考虑到苗木的观赏季节性，比如春季观赏的樱花、玉兰、紫荆、连翘等等，夏季观赏的海棠、五色梅、茉莉等等，秋季观赏的桂花、菊花等，冬季的梅花。
Taking park landscapes as an example, gardens generally require ornamental plants throughout the year. Therefore, the selection of seedlings will take into account their seasonal characteristics, such as cherry blossoms, magnolias, bauhinia, forsythia, etc. in spring, crabapple, five colored plum, jasmine, etc. in summer, osmanthus, chrysanthemums, etc. in autumn, and plum blossoms in winter.
4.种植环境
4. Planting environment
种植环境是苗木品种最重要的一环，环境不适宜，苗木移栽不成活，则一切都是空白，像香樟，在寒冷地区是不能栽种的，去年的寒冬就把沭阳地区的香樟枝叶全部冻死了，非常影响苗木的生长以及观赏。所以苗木一定要选择适合土壤、气候环境的品种。
The planting environment is the most important aspect in selecting seedling varieties. If the environment is not suitable and the seedlings cannot be transplanted, everything is blank. Like camphor tree, it cannot be planted in cold regions. Last year's cold winter froze all the camphor tree branches and leaves in Shuyang area, greatly affecting the growth and viewing of seedlings. So seedlings must choose varieties that are suitable for the soil and climate environment.
