What are conifers and broad leaved trees? 20

Conifers are mostly pine and fir trees, and there are too many species of broad-leaved trees to count! Conifers such as: roe deer pine, Korean pine, Chinese pine, black pine, cedar, whitebark pine, Osaka pine, five-needle pine, masson pine, Huashan pine, larch, spruce, fir, etc.

Broad-leaved trees such as: tung tree, tulipwood, silk cottonwood, bean tree, horse chestnut, green tree, coptis, acacia, linden tree, luan, soaphorn, alder, maple poplar, willow, poplar, peach, plum, pear, acacia, elm, oak, oak and so on.

Broad-leaved trees generally refer to dicot trees, with flattened, broad leaves, leaf veins into a network, evergreen or deciduous leaves, generally broad leaf surface, leaf shape with different tree species and a variety of shapes of perennial woody plants. Some are evergreen and deciduous mostly in autumn and winter, when the leaves fall off the branches. A forest made up of broad-leaved trees is called a broad-leaved forest.

Broad-leaved trees have great economic value, and many of them are important timber species, some of which are precious timber, such as camphor trees, nanmu, etc. All kinds of fruits are broad-leaved trees. There are many types of broad-leaved trees, collectively known as hardwoods.

Species: 1. Deciduous species: ginkgo, poplar, weeping willow, silver bud willow, elm, yellow cypress, white magnolia, Xinyi, Erqiao magnolia, red leaf plum, red leaf peach, plum blossom, cherry blossom, acacia, acacia, acacia, Acacia truncatum, crape myrtle, pomegranate, hibiscus, woody ivory, etc.

2. Evergreens: Ficus microphylla, Alpine ficus, weeping ficus, silver birch, mountain magnolia, magnolia, white orchid, lampstand tree, camphor, bergamot, daidai fruit, French holly, privet, osmanthus, Tianzhu gui, Du Ying, Zhennan, etc.

Uses: Broad-leaved trees are suitable for construction engineering, wood packaging, machinery manufacturing, shipbuilding, vehicles, bridges, sleepers, furniture, pit wood and plywood, etc.

The conifer species that grow in the border areas are cedar, fir, spruce and larch; Soft tree species include birch, aspen, linden; The hard-leaved broad-leaved tree species are oak, ash 、..Compared to coniferous forests, mixed forests have a much richer variety of flora and fauna. (Deciduous) broad-leaved trees are luxuriant in spring and summer, and have a good concealment effect; More importantly, the shape of the branches is suitable for the stable construction of the nest, so the vast majority of nests are built on broad-leaved trees;

There are relatively few birds nesting on conifers, especially large birds are troubled by overly dense foliage, which is exactly what small birds expect, so conifers are suitable for building small nests;

The birds that nest in the cave are basically meat-eating, and their "control" over the branches and leaves is relatively poor, so it is difficult to collect suitable nest materials, but the strong beak can be used to clean up the residue of the tree hole, so the nesting in the tree hole is a way to promote the strengths and avoid the weaknesses.

In fact, it is difficult to clearly define the rules of the selection of bird nesting sites, mainly due to the inertia of long-term living habits, and birds know how to choose the safest and most effective nesting method according to their living environment.

According to the leaves, trees are mainly divided into two types: broad-leaved trees and conifers. For example, aspen and maple are broad-leaved trees, while pine, cypress, and cedar are conifers.

In terms of leaf types, there are two main types of trees: conifers and broad-leaved trees.

Conifers include: cedar, ginkgo, giant sequoia, tabuliformis pine, etc.

Broad-leaved trees include: poplar, magnolia, aspen, red leaf peach, etc.

Broad-leaved trees do not refer to trees with very large leaves, such as plantain trees, but are broadly defined as broad-leaved trees other than conifers, and trees with normal leaves, such as camphor trees, cypress poplars, etc. Knowing what broad-leaved trees are, I think this tree species is no longer unfamiliar, because you can see it as soon as you go out.

Broad-leaved trees refer to trees with broad leaves, which are divided into two categories: evergreen and deciduous trees, both of which are common and closely related to human life. Most of the economic tree species planted in China are broad-leaved trees, and most of the street trees and landscaping are also broad-leaved trees.

1. Evergreen broad-leaved trees

Evergreen broad-leaved trees are often used as landscaping, we are familiar with camphor trees, osmanthus trees, banyan trees, heather, magnolia, holly, etc., most of these trees can be seen when we go out, and are mostly planted in gardens and communities.

2. Deciduous broad-leaved trees

Common deciduous broad-leaved trees include poplars, weeping willows, elms, plum trees, cherry trees, crape myrtle trees, hibiscus, pomegranates, etc., and these broad-leaved trees are mostly used as street trees or ornamental trees.

1. Ordinary people's understanding

In the eyes of ordinary people, there are three types of leaves, one is the needle-pointed type (pine, cypress, etc.), the second is the ordinary normal-sized leaves, and the third is the large leaves like the banana tree. However, it is generally believed that only large-leaved trees such as plantain trees are broad-leaved trees.

2. Scholar's definition

The definition of scholars is that except for the trees with needle-pointed leaves, other trees with normal or large leaves are broad-leaved trees, which means that the camphor trees and cypress poplars that we commonly see are broad-leaved trees.

Deciduous: Common deciduous broad-leaved forests include weeping willow, magnolia, Xinyi, plum blossom, cherry blossom, and wood hibiscus.

Aspen and so on. Evergreens: Ficus microphylla, magnolia.

White orchids and other evergreen broad-leaved forests, among which the magnolia trees are majestic and magnificent. Maintenance method: pruning is carried out in the growth period or dormant period of broad-leaved forest, and compound fertilizer is applied during the growth period.

1. Deciduous

Broad-leaved forests are divided into two categories, among which the common deciduous broad-leaved forests include weeping willow, magnolia, Xinyi, plum blossom, cherry blossom, wood hibiscus, aspen, etc., among which the white magnolia is a valuable ornamental tree in the garden, and the plum blossom is the four gentlemen.

The flower language of the wood hibiscus is the beauty of slenderness.

2. Evergreen

There are various varieties of evergreen broad-leaved forests, and the common ones are ficus microphylla, magnolia, white orchid, osmanthus, and eucalyptus.

Silver birch, etc., among which the magnolia tree is majestic and magnificent, the flowers are beautiful and atmospheric, and rich in aroma, and the silver birch is one of the main greening tree species in the city.

3. Maintenance method

In the process of maintaining broad-leaved forests, it needs to be pruned regularly, which can be carried out in the dormant period or the growth period, which can reduce the damage to the plants, and the fertilizer should be supplemented in time during the growth period, and the fertilizer can choose nitrogen, phosphorus and potassium.

Balanced ternary compound fertilizer.

The four common broad-leaved trees are round elm, magnolia, camphor and alpine ficus, and elm is mostly distributed in North China and Southwest China. Magnolia is a deciduous broad-leaved tree and is often planted as an ornamental tree in the garden; Camphor camphor tree, also known as camphor and camphor, belongs to the evergreen broad-leaved tree species; Alpine ficus is mostly distributed in Guangxi and belongs to tropical tree species.

1. Elm

Broad-leaved trees usually refer to broad-leaved trees, so which trees are broad-leaved trees, elm is a type of broad-leaved tree. Elm is also known as spring elm, home elm, mostly distributed in North China, southwest China and other regions, elm belongs to deciduous trees, its plants can grow up to 25m, its bark is mostly dark gray.

2. Magnolia

Magnolia is a deciduous broad-leaved tree, native to the Yangtze River basin, often planted as a garden ornamental tree, its bark is mostly dark gray, blooms in February and March every year, and bears fruit in August and September. Magnolia likes light and is afraid of waterlogging, so it is necessary to let the plants receive sufficient light when planting, and the amount of watering should be controlled.

3. Camphor

Camphor tree, also known as camphor and camphor, belongs to the evergreen broad-leaved tree species, mostly distributed in Taiwan, Jiangxi, Fujian and other regions, its trees can resist chlorine and carbon dioxide, and belong to environmentally friendly trees. The camphor tree will emit a fragrance, which has the effect of repelling insects, and the common mothballs in life are made of the camphor tree.

4. Alpine ficus

Alpine ficus belongs to the mulberry tree, mostly distributed in Guangxi, Sichuan and other regions, its plants can grow up to 30m. Alpine ficus is a tropical tree species that likes to grow in an environment with high temperature and high air humidity, so it is rarely planted in Shanghai, and it is difficult for alpine ficus to survive the winter in Shanghai.
