What are the characteristics of maple poplar? What are the characteristics of maple poplar?

Maple poplar. It is a tall tree, it can grow to a height of 30 meters, it is a real towering tree, in our Shuyang local maple poplar tree is called money string string, its fruit hangs on the branch to grow, very much like the appearance of copper coins strung together. Maple poplar trees mainly grow in small rivers and woods at an altitude of 200-1300 meters, and are planted in most places in China, mainly as street trees or garden planting.

The maple poplar is very similar to most plants, it is a tree that likes light conditions, it does not have shade tolerance, so we have to choose a good planting place when planting, its root system is very developed, it can root several meters deep, and the lateral roots are also relatively developed, growing horizontally in the soil, so we don't need any soil environment when planting. Maple poplar trees are very cold and drought tolerant, and can survive in environments of tens of degrees below zero, and can survive the winter without frost protection measures if planted in southern regions. In the growth process of maple poplar trees, insect control measures should be carried out, generally focusing on prevention, spraying some thiamethoprid spray to kill pests and diseases on the surface of the leaves.

Botanically speaking, maple poplar belongs to the Juglans family. The bark is black-gray, the leaves are alternate, the flowers are unisexual, yellowish-brown, monoecious, the fruit is oblong and string-shaped, sticky. The inflorescence is drooping, 20-30 cm long, the nut is nearly spherical, 2-3 cm long, obliquely spreading, flowering from April to May, and ripening from August to September.

It can be used all over the body. Maple poplar is a deciduous tree, up to 30 meters high, with flaky pith branches; The bare buds are densely covered with brown hairs, and there are overlapping sessile latent buds underneath.

Pinnate; The leaf axis has narrow wings, 5-10 cm long, the margin is finely serrate, and the apical leaflets are sometimes not developed. Maple poplar has a broad canopy, dense branches and leaves, fast growth, strong adaptability, and is mostly planted as shade trees and street trees in the Jianghuai River Basin, and because of the developed root system of maple poplar, it is more resistant to water and moisture, and is often used as a waterside revetment embankment and windbreak tree species. Maple poplar trees like a sunny and warm and humid climate, and are also more cold-tolerant, with less strict requirements for soil, deep roots, obvious taproots, developed lateral roots, and strong germination and tillering.

The shape of the maple poplar tree has both the strong and upright maple tree and the elegant willow, which reflects the characteristics of the tree family in softness and rigidity.

Maple poplar genus. fengyangshu

pterocarya

Pterocarya Kunth is a genus of maple poplar, Juglans family, 8 species, distributed in the north temperate zone, about 7 species in China, and is produced in both north and south, especially P. maplecaryaStenoptera is the most common and is cultivated as a street tree in Shanghai and other major cities. arbor, leaves shed, alternate, pinnate compound, without supporting leaves; leaflets nearly sessile, serrate; The flowers are unisexual, open at the same time as the leaves, and are drooping inflorescences; Male flowers are born in the axils of bracts; Sepals 1 4;stamens 6 18; Female flowers have bracts 1 and bracts 2; Ovary 1, enclosed in a 4-tooth fissure source disturbed total bract, columella 2-lobed; 1 ovule; The fruit is a nut with wings2.

Sweetgum and maple poplar are both common trees, and they have some differences in the following ways:

1.Species: Sweetgum is a sweetgum tree, which is a deciduous tree with a height of up to 30 meters and a diameter at breast height of up to 1 meter, and its bark is grayish-brown.

The maple poplar is a large tree of the genus Maple poplar of the Juglans family, the height can also reach 30 meters, the diameter at breast height can also reach 1 meter, the bark color is dark, gray to dark brown and several colors.

2.Leaf shape: The shape of the leaves of sweetgum is usually palmate, trilobed, while the leaves of maple poplar are pinnate compound leaves and are smaller in shape.

3.Bark characteristics: The bark surface of sweetgum is usually smooth and grayish-brown in color. The bark of the maple poplar has obvious longitudinal cracks and is darker in color, gray to dark brown.

4.Growing environment: Sweetgum prefers a warm and humid climate, prefers full sunlight, and Xingxiao stove has strong adaptability to the soil and can grow in an arid and barren environment. Maple poplar, on the other hand, prefers to grow in a humid environment and has relatively low light requirements.

5.Distribution: Sweetgum is mainly distributed in the central and southern regions of China, while maple poplar is mainly distributed in the north.

In general, there are some differences between sweetgum and maple poplar in terms of species, leaf shape, bark characteristics, growing environment, and distribution range.

The kind is different. The difference between sweetgum and maple poplar is that the types are different.

1. Sweetgum, also known as sweetgum tree, deciduous tree, up to 30 meters, the diameter at breast height can reach 1 meter, and the bark is gray-brown. It likes warm and humid climates, likes light, and is resistant to drought and barrenness.

2. Maple poplar (scientific name: is a plant of the family Peach and Poplar genus. large trees, up to 30 meters tall and up to 1 meter diameter at breast height; The bark of young trees is smooth, light gray, and in old it is deeply longitudinally lobed; twigs grey to dark brown with grayish-yellow pores; The buds have stalks.

Maple poplar, a highly deciduous tree, is water-tolerant and cold-tolerant, and is an excellent garden plant. Also known as "water hemp willow", "zelkova willow", "swallow tree", "hemp willow" (Hubei), "centipede willow" (Anhui), is a plant of the genus Maple poplar of the Juglans family. Its branches are luxuriant, the flowering and fruiting period is long, and it has a good role in beautifying and greening urban garden roads.

Maple poplar is also known as fir willow (Shandong), water locust tree (Nanjing) and so on. It is widely distributed in our country, it is a deciduous tree, as early as 200 years ago, farmers in Shandong Province used it to graft walnuts, and it can bear fruit after grafting Acacia 2 5 years, with strong adaptability and developed root system, but guess the preservation rate of grafted walnuts of old maple poplar is very low, and it is not suitable to vigorously promote it in production. From the grafting experience and evaluation, the current rootstock of grafted walnut is suitable for common rootstock and kernel spike in the north, and wild walnut and iron walnut in the south.

large trees, up to 30 meters tall and up to 1 meter diameter at breast height; The bark of young trees is smooth, light gray, and in old it is deeply longitudinally lobed; twigs grey to dark brown with grayish-yellow pores; The buds have stalks, densely covered with rust-brown shield-like glands. The leaves are mostly even-numbered or odd-numbered pinnate compound leaves, 8-16 cm long (sparsely up to 25 cm), petioles 2-5 cm long, leaf axes with wings to wings not very well developed, and the petioles are covered with sparse or dense short hairs; leaflets 10-16 (sparse 6-25), without petioles, opposite or sparsely opposite, oblong-elliptic to oblong-lanceolate, about 8-12 cm long, 2-3 cm wide, apex often obtuse or sparsely acuminate, base skewed, 1 side wedge-shaped to broadly wedge-shaped, 1 side below rounded, margins finely serrated, with fine pale verrucous protrusions above, very short star-like hairs along the midrib and lateral veins, scattered pubescence below when young, After growth, it falls off and leaves only very sparse glands and lateral veins, leaving 1 cluster of star-like hairs in the axilla.

The inflorescences of the male are about 6-10 cm long, born alone in the axils of the upper leaf scars of the last year's branches, and the inflorescence axis often has sparse star-like hairs. Male flowers often have 1 (sparse 2 or 3) developed tepals, with 5-12 stamens. The female inflorescence is apical, about 10-15 cm long, the inflorescence axis is densely covered with star-like hairs and single hairs, the lower part of the flower is 3 cm long, with 2 infertile bracts up to 5 mm long.

The female flowers are almost sessile, and the bracts and bracts often have fine star-like hairs at the base and are densely covered with glands.

The inflorescence is 20-45 cm long, and the inflorescence axis is often covered with retained hairs. The fruit is oblong, about 6-7 mm long, and often has persistent star-like hairs at the base; Fruit wings narrow, strip-shaped or broad-striped, 12-20 mm long, 3-6 mm wide, with nearly parallel veins. The flowering period is from April to May, and the fruit ripening period is from August to September.
