Five types of trees have broad prospects
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.
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.
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.
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.
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.
