Three common propagation methods of Acer truncatum

Acer truncatum is mainly produced in North China and the south of Northeast China. It likes warm, humid and semi-shaded environment. It has a certain tolerance to drought, but not to waterlogging. You can propagate through sowing, grafting and cutting. The editor will give you a brief introduction to the three common breeding methods of Acer truncatum, which can be understood by interested friends.

Acer truncatum

First, sowing seeds

The methods of sowing, grafting and cutting are commonly used in the propagation of Acer truncatum. Mainly by sowing method. Most of the sowing and raising seedlings are in spring, and they can also be sown with picking in autumn. Samara can be harvested in autumn when it changes from green to yellow. after drying, the pericarp is removed, and the seeds are sown, and they can also be dried and stored for winter, and sown in the following spring.

Sow 15 kg to 20 kg per mu, strip sowing or sowing, soak the seeds in warm water of 40ml 50C for 2 hours before sowing, remove and wash them, mix them with 2 times of coarse sand, stack them for germination, cover them with moist grass curtains, turn them every 2 days, and sow seeds in about 15 days when the seeds germinate.

Generally use field trench ridge sowing, ridge distance is 60Mel 70cm, cover soil 2cm thick after sowing, slightly suppress, cover grass to keep the seedbed moist, and seedlings can emerge after half a month. The seedlings were unearthed for 3 weeks, and the lateral buds were wiped once from June to July. The one-year-old seedlings are about lm.

Because of the cold and dry winter in Beijing, the shoots are vulnerable to frost damage, so it is necessary to move the seedlings into the false planting ditch to survive the winter after falling leaves in autumn. After transplanting in spring, we should pay attention to the cultivation of the trunk and cut off the lateral branches in time. Generally, 4-5-year-old seedlings can be planted in the nursery.

2. Grafting

The superior varieties can be propagated by grafting, and the rootstocks can use 4 ~ 5-year-old Acer seedlings. The buds are easy to survive when the buds are inflated in spring, and the cutting is carried out from March to April. The bud grafting is carried out in May-June or mid-late September, and the interface is easy to heal.

Third, cuttage

Cuttings can be cut with semi-hard branches and are easy to take root. Cuttings are generally carried out in the growing season from May to June, and annual branches are generally used as cuttings, cut into 8 cm to 10 cm long, soaked in ABT rooting powder 100ppm for 2 hours, and then obliquely inserted on the cutter.

Propagation method of Acer truncatum the main value of Acer truncatum

Acer truncatum is an excellent tree species for shelterbelt, timber forest and industrial and mining area greening. How can such a fine tree species reproduce? What are the main values? Let's learn about it next.

I. Propagation method of Acer truncatum

The methods of sowing, grafting and cutting are commonly used in the propagation of Acer truncatum, mainly by sowing.

1. Sowing and propagation: sowing and raising seedlings are mostly in spring, and they can also be sown with picking in autumn. Samara can be harvested in autumn when it changes from green to yellow. after drying, the pericarp is removed, and the seeds are sown, and they can also be dried and stored for winter, and sown in the following spring.

Generally use field trench ridge sowing, ridge distance is 60-70 cm, cover soil 2 cm thick after sowing, slightly suppress, cover grass to keep the seedbed moist, and seedlings can emerge after half a month. The seedlings were unearthed for 3 weeks, and the lateral buds were wiped once from June to July. The one-year-old seedlings are about lm. After transplanting in spring, we should pay attention to the cultivation of the trunk and cut off the lateral branches in time. Generally, 4-5-year-old seedlings can be planted in the nursery.

2. Cutting propagation: semi-hard branches can be used in cutting, so it is easy to take root. Cuttings are generally carried out in the growing season from May to June, and annual branches are generally used as cuttings, cut into 8 cm to 10 cm long, soaked in ABT rooting powder 100ppm for 2 hours, and then obliquely inserted on the cutter.

The superior varieties can be propagated by grafting, and the rootstocks can use 4 ~ 5-year-old Acer seedlings. The buds are easy to survive when the buds are inflated in spring, and the cutting is carried out from March to April. The bud grafting is carried out in May-June or mid-late September, and the interface is easy to heal.

Second, the main value of Acer truncatum

1. Ornamental value: Acer truncatum tender leaves are red, autumn leaves are yellow, red or purplish red, the tree is graceful and the leaf shape is beautiful, so it is an excellent foliage tree species. It is suitable for shade trees, street trees or scenic forest trees. 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: hard wood for excellent construction, furniture, carving and cabinetwork. Bark fiber can be used for papermaking and substitute cotton. Acer truncatum has a wide range of uses, and the whole tree is a treasure, mainly in the following aspects:

The main results are as follows: 1. The new resource of high quality edible oil 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.

2. High-quality protein New Resource Yuanbao Maple seed contains 25% Mel 27% protein and does not contain starch, which is 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.

The above is the breeding method of Acer truncatum and the introduction of the main value of Acer truncatum. I hope it will be helpful to you. I also want to know other knowledge of Acer truncatum and continue to pay attention to us.

Reproductive Management of Acer truncatum

Cultivation and maintenance:

China Garden Network, April 24: Yuanbao Feng likes warm, humid and semi-shady environment, likes fertile and well-drained soil, and has a certain tolerance to drought, but not to waterlogging. It has strong sprouting ability, deep root and strong resistance to wind and snow, and it is better to plant in leeward, moist and side shaded places. Pay attention to drainage in the rainy season, stagnant water will lead to rotting roots. Keep the soil moist during the growing season and dry in autumn to make the leaves turn red. When transplanting in dormant period, more than 4-year-old seedlings should be transplanted with dirt. When planting, 1-1.5 kg of mature compost or stable manure was applied in the planting hole, and enough root water was poured after planting, and then organic fertilizer was applied every 1-2 years. During the dormant period, the crown should be pruned properly, and there is no need for pruning when the plant grows to more than 3 meters.
