What is the difference between pond cedar and lupus cedar?

The difference is not too big, you can search for details.

Differences: 1: Different origins.

Although it was introduced into Nanjing in the last century, the survival rate is not high, the cultivation area is not large, and the distribution is small. Metasequoia belongs to the Chinese tree species, so most of the metasequoia seen in China is native to Sichuan, China.

2: The branches are different. The young leaves of the pond cedar are diamond-shaped and do not automatically arrange into pinnae like metasequoia. The leaves of Metasequoia are automatically arranged in pinnae, and the new leaflets are strip-shaped.

3: The blades are different. The leaves of the pond fir are not developed, the small leaves grow with branches, the trunk branches are few and straighter than that of metasequoia, and the leaves of the pond fir are slender and slightly bent downward; Metasequoia leaves are linear and alternate, the metasequoia leaves are open, the leaflets are in one plane, and the trunk is branched.

4: The height is different. The height of the pond cedar can reach 25 meters, and the main trunk of the pond cedar is very straight; Metasequoia can be up to 35 meters tall and its bark is mostly brown, gray or dark gray.

5: The flowering period is different. The flowering period is in March every year, and the shape of the fruit is oblong or spherical; Metasequoia blooms in February every year.

6: The fruit is different. The fruit of the pond cedar ripens from October to November every year, and the fruit is a little large and a little round; The fruit of Metasequoia is ripe in November every year, and the fruit is a little small and a little ovate.

7: Different levels of light preference. Ikesugi doesn't like light. Metasequoia loves light.

The difference between lupus and metasequoia is manifested in the following aspects: different leaves, different branches, and different fruits.

1. The leaves are different

Both the leaves of both fir and metasequoia are strip-shaped, but if you look closely, the leaves of these two trees are not the same, and the leaves are alternate with small, long leaves. The leaves of Metasequoia metasequoia are mainly opposite, and the leaf distribution is very neat and uniform.

2: The branches are different.

There are some differences between the branchlets of the Taxus lanceolata and Metasequoia trees, which have distinctive hairy branchlets, which grow longer and droop as they grow. Metasequoia's pinnate twigs are shorter and do not droop during production, and its twigs are firmer.

3. The fruits are different

The fruits of the fir and metasequoia are spherical, but if you distinguish them carefully, there are also differences, and there are certain differences, the fruit of the fir is relatively small, the fruit is shield-shaped, and there are no obvious horizontal spines. Metasequoia fruit is larger, and the top of its scales is mostly flat and diamond-shaped, with a horizontal groove in the middle.

The main value of the fallen feather fir

1. Watching

Its branches and foliage are luxuriant, and the leaves fall late in autumn, and the crown is majestic and beautiful, and it is a beautiful tree species for gardens and road greening. In most parts of China, it can be used as industrial forests and ecological forests.

2. Economy

Its seeds are the feed that wild animals such as birds and squirrels like to eat, so they play a good role in strengthening forest parks, maintaining the biological chain of nature reserves, soil and water conservation, and conserving water sources. The wood material of Lanceolata lanceolata is light and soft, the texture is fine, easy to process, and resistant to decay, and can be used as materials for construction, poles, ships, furniture, etc.

Lupus and Metasequoia are common trees in nature, and they both have a certain ornamental value, some people don't know much about them, don't know what is the difference between them, in fact, there is a clear difference between Lupus and Metasequoia, today I will introduce this aspect of knowledge and knowledge, but also let everyone know more about Lupus fir.

The difference between lupus fir and metasequoia 1, there is a certain difference between lupus and metasequoia in the leaves, although these two plants are strip leaves, but there are also certain differences between them, the leaves of lupus fir are mostly alternate, while the leaves of metasequoia are mainly opposite, if you put the leaves of the two plants together, you can easily distinguish them.

2. The plant has a unique hairy branchlet, which will be relatively large in length when it grows, and will droop during growth, while the pinnate branchlet of Metasequoia is relatively short, and it will not droop in the process of raw search and production.

The lupus also has a unique respiration, while metasequoia does not have this property, which is the biggest difference between the two.

3. There is also a certain difference between the fruits of the fir and the metasequoia, although their fruits are the fruits of the spherical fir and the fruit of the spherical fir are relatively small, and the fruits of the water mountain are relatively large.

Metasequoia metasequoia has a flat rhomboid-shaped scale at the top, with a transverse groove in the middle, while the tumor of this plant is shield-shaped, and there is no obvious transverse scum.

Detailed introduction of Taxus lanceolata 1, Taxus lanceolata is an ancient tree species, it belongs to a strong positive, the ability to adapt to the environment is particularly strong, it is resistant to low temperature, salt and alkali, and resistant to flooding, in daily life, this plant can be planted in the plain Jin Lake, riverbank, and areas with dense water networks, in China's Wuhan and Nanjing and Hangzhou and other places, there are a large number of Lancet trees.

2. Lupus fir is a tall tree, it originally grew in North America, and later introduced to all over the world, this plant has lush branches and leaves, the tree shape is beautiful, and the leaves fall in autumn are relatively late, and its leaves will become bronze after entering the autumn, and the ornamental value is particularly high.

Not only can it be viewed, it also has a high economic value, its wood material is light and soft, and the texture is delicate, which is an excellent raw material for processing all kinds of furniture, ships and buildings.

Larch fir, also known as larch pine, is a large deciduous tree that can reach a height of 25 to 50 meters. At the young to middle age stage (under 50 years old), the trunk is perfectly straight, with a conical or umbel-shaped ovate canopy, and some plants gradually form an irregular wide canopy after 50 years. The canopy of the pond cedar is relatively narrow, and it is basically spire-shaped under 50 years old.

It is an ancient "relict plant" that is resistant to low temperature, salinity, and flooding.

It is native to North America and Mexico, and is now introduced and cultivated in Guangzhou, Hangzhou, Shanghai, Nanjing, Wuhan and Fujian in China. It is often planted in plain areas, lakes, river banks, and water network areas.

Answer]: Morphological characteristics of the genus Taxus in the family Pond Fir.

In the second year, the source of stupidity shouted that the branches were brownish-red, and the shedding twigs often erect upward;

The base of the trunk is swollen, often with knee-like respiratory roots;

Leaves conical slightly flattened, spiral-alternate, close to the branchlets, usually not bilobed;

The cones have short peduncles.

Characteristics of the wild state of the genus Taxus in the family Taxaceae:

Branchlets alternate, often enlarged at base with bent knee-like respiratory roots;

Leaves oblate, alternate, pinnate arrangement, pale green, with branchlets falling in winter;

The cones are round spherical. The leaves are linear, arranged in pinnate 2 rows on lateral branches.
