What are the characteristics of the cypress tree and what are the symbols of the cypress tree

Characteristics of the cypress tree:

First, the vitality is tenacious.

The vitality of the cypress tree is very tenacious, it can grow in any place where there is a plant to grow, no one is picky about the soil requirements, as long as there is a little soil layer to feed it, but the only difference is that the seedling cypress needs to fully absorb the sunlight to promote its own growth, the problem of watering can basically be ignored, because it is resistant to drought and cold, and this characteristic is enough to show that the survival rate of cypress is amazing, the ancients had thousands of hammers to chisel out of the deep mountains, and the fire burned if it was idle to describe bamboo, And the cypress tree is several times stronger than the vitality of bamboo.

Second, the root system is well developed.

The roots of the cypress tree are very developed, it can take root in the ground, and it can also desperately find soil through small gaps in the rocks to promote its own growth, as long as it is a little moist soil, this vigorous cypress tree can quickly take root and sprout, and can thrive in a short time, its life is so tenacious.

Third, hardy. The cypress tree also has a high aesthetic value, its tree shape is elegant, the trunk is straight, the leaves are verdant, the leaves do not fall all year round, do not change color, and stand straight. Especially in winter, when a white snow falls, many plants are covered with snow and you can't see even a little color, but the cypress tree stands proudly.

Cypress, which can be said to be the common name for cypress plants, belongs to the phylum gymnosperms, is a family of pines and firs, evergreen trees or shrubs. The leaves are small, scaly or spiny-shaped, crossed on the branches or 3 or 4 whorls, sometimes on a tree with both scaly and spiny leaves, called heteromorphic leaves. The cones are unisexual, monoecious or heterogeneous, solitary at the apex of the branch or in the axils of the leaves.

male globules with 3 8 pairs of cross-facing stamens, each stamens with 2 6 anthers, pollen without air sacs; The female has 3 16 crossed opposite or 3 4 whorls of bead scales, and each bead scale has 1 to more straight ovules on the ventral surface, and the bead scales are completely compatible with the bract scales. The cones are spherical, ripe and dehiscent or fleshy to form berries, with 1 to more seeds at the scales; Seeds are narrowly or without wings around them. There are about 150 species of cypress in 22 genera, mainly distributed in the northern and southern hemispheres.

There are 8 genera and 29 species in China, which are distributed throughout the country.

Most species occupy important positions in afforestation, sand fixation, and soil and water conservation. Undergraduate studies are usually divided into 3 subfamilies.

Arborvitae subfamily: the cones are woody, ripe and dehiscible, and the scales are not shield-shaped, mainly including Arborvitae, Arborvitae, Arhat and Cypress; C. sinensis subfamily: the cones are ripe and dehiscent in the following year, and the scales are woody and shield-shaped, mainly including Cirus spp., Cypress spp. and P. fujian spp.; Juniperaceae:

The cones are fleshy and spherical, ripe without dehiscence, only juniper and juniper. In addition, there are some cypress trees that are listed as the first batch of rare and endangered protected plants in China, and the varieties mainly include: cypress, red cypress, giant cypress, Fujian cypress, Minjiang cypress, Korean cypress, cypress, etc.

2. Female cones have 3-16 cross-opposite or 3-4 whorls of bead scales, all or part of the bead scales have 1 to most of the erect ovules at the base of the ventral surface, the dilute ovules are born between the two bead scales, and the bract scales and the bead scales are completely combined.

3. The crown of young trees is conical or ovate, and when old, it is broadly round; The bark is dark grayish-brown, longitudinally fissured, peeled off in thin strips; The twigs of the scales are thin, green, straight or obliquely upward, flattened, arranged in a plane, green on both sides, and the biennial branches are greenish-brown, slightly flattened, gradually turning reddish-brown, and cylindrical.

4. The leaves are scaly, 1 3 mm long, slightly blunt at the apex, the exposed part of the branchlets ** is triangular, there are strip-like glandular grooves on the back**, the leaves on both sides are boat-shaped, the apex is slightly incurved, there are blunt ridges on the back, and there are glandular points below the pointed ends.

5. The cones are nearly oval, usually 4 pairs of scales, 1 2 cm long, nearly fleshy before maturity, blue-green, white, woody, dehisced, reddish-brown after maturity, the top pair of scales are narrow and long, nearly columnar, with upward pointed heads at the top, and the middle two pairs of scales ovate, oval to oblong.

Cypress is a general term for cypress trees, and generally speaking, cypress is arborvitae, which is also known as cypress and cypress.

1. Appearance characteristics: cypress branchlets are flattened, leaf scales, monoecious, and the bulb flowers are solitary at the top of the branches. The cones are nearly ovate, the seeds are long ovate, the cypress is densely branched, the branchlets are numerous and numerous, the branches and leaves are dense, the early crown of the tree is completely surrounded by branches and leaves, and the other side cannot be seen from one side, like a large dark green cone;

2. Habit characteristics of cypress: more cold-tolerant, less wind-resistant. It is drought tolerant and likes moisture, but not flooding. It is resistant to barren Kaili bumper, can grow on slightly acidic to slightly alkaline soil, grows slowly, and has a very long lifespan;

Pine and cypress trees are originally trees that grow in the cold zone and high mountains, and they have formed a unique structure to protect them from the cold because they have lived in a cold environment for a long time. The leaves of the pine and cypress trees are shrunk to be needle-shaped, linear or scale-shaped, and because of the small leaf area, water is not easy to evaporate and dissipate, protecting its survival.

Some leaves have thick or waxy leaves, some have thick hairs, and if you look closely at the needles of pine trees, you can see that there are dense white hairs on them, which feel smooth to the touch, and these structures effectively prevent the evaporation of water and ensure its vitality.

When the temperature drops, it can quickly increase the concentration of cell sap, increase sugar and fat in order to prevent freezing, so even in winter, the pine and cypress trees will not lack water and dry up, ensuring the vitality of the trees forever.

There are many types of cypressesFor example, arborvitae: Arborvitae is an evergreen tree belonging to the genus Arborvitae in the family Cypressidae, and its bark is usually gray. Arborvitae orientalis is an endemic species in China, and its leaves are all scaly.

Juniper:Juniper is a gymnosperm that resembles a spherical shape with a white layer of powder on top of it, and it is native to China, but it is also cultivated in other countries around the world.
