Propagation methods and matters needing attention of Acer truncatum

Green maple is mainly distributed in the Yangtze River basin and its southern provinces in China. In China, green maple is widely distributed and is one of the excellent foliage tree species in landscaping. The economic prospect of green maple is also optimistic by everyone, and now it is often cultivated as a street tree.

Green maple

The most commonly used propagation method of Acer truncatum is sowing and raising seedlings, which has the advantages of fast propagation speed, large scale, large quantity, getting rid of the degeneration shortcomings of long-term asexual reproduction of other tree species, and good disease resistance of tree seedlings. Generally used seeds per mu of about 6cm, autumn sowing spring sowing are good, high budding rate. When the sowing row spacing is 15-20 cm, the seedlings can not be exposed to full-day light. Shading measures should be taken. The seedling height is 20 cm for the first time, and the weak seedlings are allocated for the second time. 35-40 cm for the second time, each seedling keeps a good growth space. Compound fertilizer can be applied once before the beginning of summer, please remember when it rains, if the rainfall can not wash the chemical fertilizer falling on the leaves to the ground, we should manually spray water to wash, otherwise it will cause burning.

In that year, the green maple seedlings can grow 1.2 to 1.5 meters high and have a root diameter of 0.8 to 1.3 centimeters. In the early spring of the second year, the seedlings were planted with a row spacing of 50 centimeters and 120 centimeters, and the first fertilization began one month after the seedlings were slowed down. The application amount should not be too much, and it could be buried with organic fertilizer and spread with chemical fertilizer. Weeding and watering is carried out according to the situation, and fertilization is applied once every 20 days during the peak growth period. According to this method, green maple seedlings can grow 2 to 2.3 meters high and 2.5 centimeters in diameter in two years. And the tree stem is straight, the plant is strong, it is an excellent semi-finished product seedling of street tree. The suggested retail price is 1520 yuan per tree, or you can keep the street tree for cultivation.

Propagation method of Acer truncatum the control of diseases and pests of Acer truncatum

Green maple deciduous small tree, is an excellent foliage plant, the veins of the leaves are obvious, the color is as bright as flowers, and the color is as brilliant as Xia. What are the breeding methods of green maple? How to control diseases and insect pests? Let's learn about it next.

First, the propagation method of green maple.

1. Seed propagation: sowing seeds after harvesting in October, or sowing with wet sand to the following spring, covering soil with 1~2cm after sowing, watering thoroughly, covering straw, and uncovering straw after emergence. The row spacing of strip sowing is 15~20cm, and the sowing amount per mu is 4~5kg. The seedlings are afraid of the sun and need proper shade. Seedling height 30~50cm in the same year. Transplanting should be carried out in the dormant period of deciduous leaves, the roots of the seedlings can be exposed, but the big seedlings should move with the soil ball.

2. Grafting propagation: grafting when the rootstock grows most vigorously. The seedlings must be transplanted 2-3 times. The transplant should be carried out from defoliation to pre-germination, with lodging soil. Grafting can be done by cutting grafting, leaning grafting and bud grafting. 3-4-year-old Acer mongolica seedlings are commonly used in rootstocks. The cutting and grafting is carried out when the buds of the rootstocks expand from March to April in spring, and the rootstocks should be cut off at the 50~80cm off the ground for high grafting, so that the shoot length can reach more than 50cm in the same year. Although it is troublesome to rely on the connection, it is easy to guarantee survival.

3. Softwood cutting: selecting branches of one-year-old seedlings as cuttings can greatly improve the survival rate of cuttings. In production, the branches obtained from the recommendation can be used to make ears. The cutting time should be mid-June. The survival rate of cuttings on June 17 can be as high as 74.2%-96.7%. Use 20OmeCt. GGR6 treatment of cuttings can improve the survival rate.

2. Disease and pest control of green maple

To give priority to prevention, spray carbendazim or enamylmorpholine or acylmorpholine EC + Ningnanmycin + avermectin + cyhalothrin or chlorpyrifos or acetamiprid + organosilicon 3000 times, once every 15-20 days when there is no disease, and once every 5-7 days when the disease is serious. Pay attention to the alternate use of medicine. The common pests of green maple pests are grubs, mole crickets, beetles, thorns, aphids, longicorn beetles, heart borer, black creeping and bare-shouldered longicorn beetles.

Grub, mole cricket and other control of underground pests grub, mole cricket and other gnawing on the roots and stems of seedlings, resulting in the death of seedlings. 1000 times of phoxim EC or 48% Lesben EC can be used to mix fine soil or water roots.

Control of beetles, thorns, aphids and other pests that invade branches and leaves, such as beetles, thorns, aphids, red spiders, etc., often eat red maple leaves, resulting in poor seedling growth, can be used avermectin, catch fast, omethoate 800mm 1000 times spray.

The control of longicorn beetles, heart borer, etc. against stem borer, longicorn beetles, heart borer, etc., which harms the branches of Acer truncatum, resulting in the withered branches or even the death of big seedlings. 2000-3000 times liquid spray such as fenvalerate and green kungfu can be used, or dichlorvos and other pesticides can be injected into the branches at the entrance of the insect channel, and sealed with sticky mud.

The above is the introduction of green maple breeding methods and green maple disease and pest control. I hope the above content will be helpful to everyone. I also want to know other green maple knowledge and continue to pay attention to us.

The characteristics of green maple, its planting method and matters needing attention, the difference between green maple and chicken claw maple

Green maple, also known as: chicken claw maple, deciduous small tree; crown umbrella. The bark is smooth. The bark is dark gray. Branchlets purple or lavender green, old branches grayish purple. Leaves suborbicular, base cordate or subcordate, palmate, densely acutely serrate. What are the characteristics of the breeze? What is the method of growing it? Come and learn from the editor.

The characteristics of green maple

Green maple is a small deciduous tree, mainly distributed in China, mainly distributed in the Yangtze River Basin of China. Green maple leaves are beautiful in shape, green in spring and summer, bright red in autumn, brilliant as glow, it is an excellent variety of foliage. Green maple will produce purple flowers around May, and then bear fruit. October is the period when the fruit of green maple ripens.

The difference between Acer truncatum and Acer chinensis

1. The similarities between green maple and chicken claw maple

Green maple and chicken claw maple are deciduous small trees of the Aceraceae family, belonging to the maple. Their growth habits are similar, they all belong to weak positive plants, like to grow in semi-overcast and humid environment, and are not resistant to cold and waterlogging. Acer truncatum and Acer truncatum both like acidic or neutral soil with good drainage, and grow rapidly and in good condition in moist, loose, fertile and well-drained soil.

Green maple and chicken claw maple are of great ornamental value and are very suitable for potted plants or bonsai planting indoors or for ornamental gardens.

2. The difference between green maple and chicken claw Acer.

Green maple must be chicken foot maple, but not all chicken foot maple is green maple. Chicken claw maple alias lobular five-pointed crow maple, A Douxian, willow leaf maple.

From the point of view of appearance, the difference between green maple and chicken claw maple is reflected in its tree height, leaf shape, leaf color and so on.

Acer frutescens generally has a height of 6-7 meters and belongs to branchlets with thin waist and 7-9 cracks in palm shape, while green maple can be as high as 10 meters in height and 5-7 cracks in palm shape.

Acer frutescens has a heart-shaped base, a tail-shaped leaf tip, a serrated edge, and red branches. The base of the green maple is wedge-shaped or heart-shaped, the leaves are slender and oval, the top of the leaves are pointed, the edges are serrated, the leaves have fine hairs on the surface, and the branches are generally cyan or gray. Acer maple may have red leaves all the year round, and green maple leaves are as green as shade.

Planting method of green maple

1. Open field cultivation of Acer truncatum

Green maple has strong vitality, and open-field cultivation should choose places with high dry and sunny topography, loose and fertile soil and deep soil layer. Do not plant in low-lying stagnant water, heavy soil, otherwise the growth of green maple will be poor. Turn the soil deeply and apply rotten organic fertilizer before planting. It is appropriate to take soil blocks when planting in order to protect the root system and improve the survival rate. There is one thing to pay attention to here: green maple should be watered thoroughly after planting.

Open field cultivation of green maple, generally apply organic fertilizer 3 times a year, to prevent partial application of nitrogen fertilizer, pay attention to apply more phosphorus, potassium fertilizer, otherwise the leaf color is not bright.

2. Potted planting of green maple

Potted green maple can be cultivated with a mixture of rotten leaf soil, garden soil and a small amount of river sand, plus a small amount of rotten cake fertilizer as base fertilizer.

When potted green maple is cultivated, thin cake fertilizer is usually applied once a month from spring sprouting, and potash fertilizer is applied in September, such as 0.5%, 1% potassium sulfate solution or plant ash leaching solution, which will make the green maple leaves bright.

When cultivating green maple in open field, we should pay attention to watering and weeding, especially in dry weather. When planting green maple, often weed and loosen the soil, which can increase the soil permeability, which is conducive to the development of the root system of green maple.

Potted green maple, the growing season watering should be adequate, but should not be too much, in order to keep the pot soil moist. Spring and autumn can be put on the balcony or courtyard training, summer moved to semi-shade, pay attention to appropriate shade, prevent hot sun exposure, resulting in scorched leaf edge. If you need to watch the maple indoors, it is appropriate to put the green maple in a place with sufficient light, and pay attention to the ventilation. After placing it for a period of time, move it to the outdoor sunny place for cultivation. Before entering winter in the north, the green maple should be moved to a cold room in time to spend the winter, put in a room with a room temperature of 0-5 ℃, and keep the basin soil dry to survive the winter safely. The green maple should be pruned in combination with plastic surgery after falling leaves in winter every year.
