What are the planting prospects of Yuanbao maple, "gold ingot and Yuanbao"? What are the cultivation techniques? What is the difference between Wujiaofeng and Wujiao maple?

Acer truncatum belongs to Aceraceae and Acer genus. It is a deciduous tree with a height of 8m and 10m, and its bark is split longitudinally. Yuanbao Maple is a treasure all over its body. It is named because the Samara is shaped like the ancient Chinese "gold ingot Yuanbao". It is an endemic tree species in China. What are the planting prospects of Yuanbao maple? What are the cultivation techniques?

Acer truncatum is a deep-rooted tree species with strong sprouting power, slow growth and long life; it prefers light, shade tolerance, side shade, suitable temperature, cool and humid climate, and cold tolerance, but too dry and cold is disadvantageous to growth. Deciduous trees, up to 10m high, simple leaves opposite, palmately 5-lobed, lobes apex acuminate, sometimes middle lobes or middle 3-lobed and 3-lobed, leaf base usually truncated, the lowest two lobes sometimes spreading downward. Flowers small and yellowish green, flowers in terminal Cymes, April flowers and leaves together. The Samara is flat, the wing is wide and slightly longer than the core, shaped like a treasure.

Planting prospect of Acer truncatum

Planting profit

Acer truncatum, which not only has strong cold and drought resistance, is outstanding in wind prevention and sand fixation, soil and water conservation, but also becomes the "new darling" of urban and rural greening because of its red leaf landscape with its winter characteristics. Not only that, Acer truncatum is also a valuable woody oil.

In a piece of Yuanbao Maple Garden in Yangjiagou Village, Xinglin Town, Fufeng County, under the dense maple leaves, there are green fruits shaped like "Jinyuanbao", which wobble slightly in the breeze. Wang Gaohong, the owner of the maple garden, said that Fufeng developed Yuanbao maple earlier, especially in recent years. A 50-mu Yuanbao maple base produces 2500 kilograms of maple seeds and earns more than 100,000 yuan. In addition, the company adopts the production and management mode of "company + expert + base + peasant household" to drive more than 20 nearby villages and towns to develop more than 20,000 mu of Yuanbao maple seedlings. Last year, more than 2400 farmers sold more than 20 million seedlings, with a sales income of more than 10 million yuan and a per capita income of more than 4000 yuan. Yuanbao Maple has become a major industry for local people to shake off poverty and become rich.

Market value

1. Ornamental value:

Acer truncatum tender leaves red, autumn leaves yellow, red or purplish red, beautiful tree posture, beautiful leaves, is an excellent foliage tree species. It is suitable to be used as shade trees, street trees or scenic forest trees, and now it is mainly used for road greening. Acer truncatum is shady, warm, cool and humid climate, strong cold resistance, loose requirements on soil, can grow in acid soil, neutral soil and calcareous soil, strong resistance to sulfur dioxide and hydrogen fluoride, and strong ability to absorb dust. Is an excellent shelterbelt, timber forest, industrial and mining area greening tree species.

2. Economic value:

The hard wood is used for excellent construction, furniture, carving and cabinetwork. Bark fiber can be used for papermaking and substitute cotton.

3. New resources of high quality edible oil:

It has large seed particles and high oil content. The oil content of Acer truncatum seed is 48%, and the oil extraction rate of machine press is 35%, which is higher than that of rapeseed. Acer truncatum is a semi-dry oil containing oleic acid and linoleic acid, in which essential fatty acids-linoleic acid and linolenic acid are up to 53%. They are of good oil quality and are rare in edible vegetable oil.

4. New resources of high quality protein:

Acer truncatum kernels contain 25% Mel 27% protein, no starch, and are rare in plant seeds. After the oil is extracted from the kernel, the oil meal is a good edible protein. According to the determination, the protein of Yuanbaoshu contains 9 kinds of essential amino acids for human body, which is a complete protein. The high-quality food prepared is delicious and is an ideal protein resource.

Key points of cultivation of Acer truncatum

Select good varieties to cultivate seedlings. The individual morphology of Acer truncatum and Acer truncatum is not easy to distinguish or vary greatly. Single seedlings with strong dryness and large annual growth should be selected for flat stubble planting, and the early density should be appropriately increased. It is appropriate to cultivate stem shape with 1200 ~ 1500 plants per mu, cultivate and replant again in about 3 years, and cultivate large seedlings with DBH above 5cm at the density of 200 ~ 450plants per mu. Should not choose too sticky soil to raise seedlings, to drain well, otherwise it is easy to rot roots. Transplant more than 4-year-old seedlings with soil balls or containers directly, otherwise the survival rate is low.

The difference between Acer truncatum and Acer truncatum

Acer truncatum and Acer truncatum are both Aceraceae trees with beautiful tree shape, beautiful leaves and fruits, and red leaves in autumn. So what are the differences between Acer truncatum and Acer truncatum? It is mainly distinguished from the morphological characteristics of them.

1. The height of the tree: compared with Acer truncatum, the tree potential of Acer truncatum is relatively low. Acer truncatum can grow up to about 13 meters, which is weaker, while Acer truncatum can be as high as 20 meters.

2. Bark: the dry bark of Acer truncatum is grayish yellow, shallowly longitudinally split, the branchlets are grayish yellow (annual branches are tender green), smooth and glabrous, while the dry bark of Acer truncatum is thin and grayish brown, and the twigs are sparse when they just grow, and then gradually fall off.

3. Leaves: both are simple opposite leaves, lobed palmately, Acer truncatum and Acer truncate, lobes acuminate, leaf base usually truncated, thin heart-shaped, both sides glabrous; and Acer truncate, leaf palmately lobed, leaf base often 5-lobed, leaf base often heart-shaped, lobes ovate-triangular, entire, both sides glabrous or only vein axils tufted on both sides, reticulate veins obviously raised on both sides.

4. Fruit: the flowers of Acer truncatum and Acer truncatum are polygamous, yellowish green, mostly terminal corymbose. Their fruits are Samara, the fruit of Acer truncatum is obtusely angled, the wing is about 2 times or more than the kernel, and the core is flat. The fruit wings of Acer truncatum spread slightly at right angles, the core is larger, and the wing is wider than or slightly longer than the core, which is similar to Yuanbao.

5, seedlings: under the same conditions, the growth rate of Acer truncatum seedlings is faster, the lateral branches are less, generally, the height of one-year-old seedlings is more than 1 meter; the growth rate of Acer truncatum seedlings is slower, there are more lateral branches, and the height of one-year-old seedlings is generally 50-80 cm.

The difference between Acer truncatum and Acer truncatum is mainly reflected in its morphological characteristics. Planting Acer truncatum can not only beautify the environment, but also absorb harmful gases such as smoke and dust. In addition, Acer truncatum has strong adaptability to urban environment and less diseases and insect pests, so it is the most widely distributed species of Aceraceae in China.
