The trident maple (Acer buergerianum) originates mainly from North China and the southern part of Northeast China. It prefers warm, humid and semi-shaded environments, has a certain degree of drought tolerance, but is not tolerant of waterlogging. It can be propagated by sowing, grafting and cuttings. Here is a brief introduction to the three common propagation methods of the trident maple.

Trident Maple

I. Sowing

The trident maple is commonly propagated by sowing, grafting and cuttings, with sowing being the main method. Seedling raising by sowing is mostly done in spring, or in autumn by sowing immediately after harvest. In autumn, when the samaras turn from green to yellow, they can be harvested; after drying in the sun, the fruit coat is removed and the seeds are sown immediately, or they can be stored dry over winter and sown in spring the following year.

The sowing rate is 15 kg to 20 kg per mu; either drilling or broadcasting may be used. Before sowing, soak the seeds in warm water at 40-50C for 2 hours, remove and wash them, then mix them evenly with twice their volume of coarse sand, pile them indoors to promote germination, cover them with a moist straw mat, and turn them once every 1-2 days. After about 15 days, when about 1/3 of the seeds have germinated, they can be sown.

In the Beijing area, because the winter is dry and cold and the shoot tips are prone to freezing damage, the seedlings need to be moved into a trench for heeled-in storage after leaf fall in autumn to overwinter. After transplanting in spring, attention should be paid to training the main trunk and side branches should be pruned in time; generally, 4-5 year old seedlings can be lifted from the nursery for planting out.

II. Grafting

Superior varieties can be propagated by grafting. The rootstock can be 4-5 year old maple seedlings. Approach grafting is easy to succeed when the buds swell in spring; cleft grafting is carried out in March-April; bud grafting is carried out in May-June or mid-to-late September, and the graft union heals easily.

III. Cuttings

Semi-hardwood branches can be used for cuttings and root easily. Cuttings are generally taken during the peak growth period from May to June, usually using one-year-old branches as cuttings, cut into 8 cm to 10 cm lengths, soaked in 100 ppm ABT rooting powder for 2 hours, then inserted obliquely into the cutting bed.

Propagation Methods of the Trident Maple and Its Main Value

The trident maple is an excellent tree species for shelterbelts, timber forests and the greening of industrial and mining areas. How is such an excellent tree species propagated? What are its main values? Let's learn about them together below.

I. Propagation Methods of the Trident Maple

The trident maple is commonly propagated by sowing, grafting and cuttings, with sowing being the main method.

1. Propagation by sowing: Seedling raising by sowing is mostly done in spring, or in autumn by sowing immediately after harvest. In autumn, when the samaras turn from green to yellow, they can be harvested; after drying in the sun, the fruit coat is removed and the seeds are sown immediately, or they can be stored dry over winter and sown in spring the following year.

Generally, furrow drilling in the field is used, with a ridge spacing of 60-70 cm. After sowing, cover with 2 cm of soil, press down lightly, and cover with grass to keep the seedbed moist; seedlings will emerge after half a month. Thin the seedlings 3 weeks after emergence, and remove side buds once in June-July. One-year-old seedlings reach about lm in height. After transplanting in spring, attention should be paid to training the main trunk and side branches should be pruned in time; generally, 4-5 year old seedlings can be lifted from the nursery for planting out.

2. Propagation by cuttings: Semi-hardwood branches can be used for cuttings and root easily. Cuttings are generally taken during the peak growth period from May to June, usually using one-year-old branches as cuttings, cut into 8 cm to 10 cm lengths, soaked in 100 ppm ABT rooting powder for 2 hours, then inserted obliquely into the cutting bed.

II. Main Value of the Trident Maple

1. Ornamental value: The young leaves of the trident maple are red, and the autumn leaves are yellow, red or purplish red. With its graceful tree form and elegant leaf shape, it is an excellent foliage tree species. It is suitable as a shade tree, street tree or landscape forest species. It is now mostly used for road greening. The trident maple is shade tolerant, prefers a cool and humid climate, is strongly cold hardy, and is not demanding about soil; it can grow in acidic, neutral and calcareous soils, has strong resistance to sulfur dioxide and hydrogen fluoride, and also has a strong ability to adsorb dust. It is an excellent tree species for shelterbelts, timber forests and the greening of industrial and mining areas.

2. Economic value: The wood is hard and is an excellent material for construction, furniture, carving and joinery. The bark fiber can be used for papermaking and as a substitute for cotton. The trident maple has a wide range of uses, and the whole tree is a treasure, mainly in the following aspects:

1. A new resource of high-quality edible oil: Its seeds are large and high in oil content. The kernel of the trident maple contains 48% oil, and the oil yield by machine pressing is 35%, higher than that of rapeseed. Trident maple oil is a semi-drying oil containing oleic acid and linoleic acid, among which the essential fatty acids - linoleic acid and linolenic acid - reach as high as 53%. The oil quality is excellent and is rarely seen among edible vegetable oils.

2. A new resource of high-quality protein: The kernel of the trident maple contains 25%-27% protein and no starch, which is rarely seen among plant seeds. After the oil is extracted from the kernel, the oil cake is a very good edible protein. According to measurements, the protein of the trident maple contains 9 kinds of amino acids essential to the human body and is a complete protein; the high-quality food made from it is delicious and is an ideal protein resource.

Propagation and Management of the Trident Maple

Cultivation and care:

China Landscape Web, April 24 news: The trident maple prefers warm, humid and semi-shaded environments, and prefers fertile, well-drained soil. It has a certain degree of drought tolerance, but is not tolerant of waterlogging. It has strong sprouting ability, a deep root system, and relatively strong resistance to wind and snow; planting it in a wind-sheltered, humid place with side shade is even better. Pay attention to drainage during the rainy season, as water accumulation will cause root rot. Keep the soil moist during the growing season, and keep it dry in early autumn to help the leaves turn red. Transplant during the dormant period; when transplanting large seedlings 4 years old or older, a soil ball is required. When planting, apply 1-1.5 kg of decomposed compost or barnyard manure in the planting hole, water thoroughly with settled water after planting, and thereafter apply organic fertilizer once every 1-2 years. Prune appropriately during the dormant period to establish the crown; once the plant grows to more than 3 m, no further pruning is needed.
