Conservation and Management of Acer palmatum Bonsai

Bonsai maintenance and Management of Acer maple

Placement site:

Acer should be placed in a ventilated, light-transparent, warm and humid place. Summer should be properly shaded to prevent exposure in the hot sun. However, if the leaves turn red in autumn, they need sufficient light before they can turn red in autumn. Put it indoors in winter to prevent the basin soil from drying and freezing.

Chicken claw maple bonsai watering:

At ordinary times, it is appropriate to keep the basin soil moist, especially in the period of sprouting and releasing leaves, not dry. After entering autumn, the leaf color turns red, and the basin soil should be dry. Watering in summer should be in the morning and evening to avoid sharp changes in soil temperature and affect the physiological function of roots. It is advisable to dry a little after autumn.

Chicken claw Acer bonsai fertilization:

In the prosperous period of growth in spring and summer, thin fertilizer and water can be often applied, and attention should be paid to increase the composition of phosphorus and potassium fertilizer, which is beneficial to the beauty of leaf color. If the fertilizer is insufficient, when the autumn frost attacks, it is often unable to turn red and fall into fallen leaves.

Pruning: it is mostly carried out in the dormant period after deciduous leaves, cutting off diseased and weak branches, cross branches, parallel branches and overlapping branches, and truncating the over-long branches of the same year according to the shape of the tree, generally leaving 1-2 nodes per branch. It should not be pruned during the growing period, so as to avoid the outflow of sap from the wound and affect growth.

Chicken claw maple bonsai turning basin:

Every 2-3 years, it is best to turn the basin before the germination period, remove the old 1B2 soil, replace it with fertile and loose rotten leaf soil or pond soil, and mix with appropriate amount of rice chaff ash and sand. Pest control: the main diseases of Acer chinensis are brown spot and powdery mildew, which can be controlled by spraying Bordeaux liquid or stone sulfur mixture. The main pests are diamondback moth, coir moth and longicorn beetles, which can be sprayed with 1500 times of dichlorvos emulsion.

Production method and maintenance management of Acer maple bonsai

(1) Botanical knowledge

It belongs to the family Aceraceae and Acer. Deciduous small trees or shrubs, branches slender and smooth, annual branchlets brown-red. Simple leaves opposite, palmately 7-9-parted, with heavily serrated margin, young leaves turquoise, turning red in autumn, brilliant like Zhaoxia. The purplish red floret forms the corymb and blossoms in April. Samara is small and purple-brown when ripe.

Main varieties and forms

1. Red maple (var.atropurpureum (Venh.) Schwer) has red or purplish red leaves all the year round, deep lobes, sparse branches and slightly larger Samara than the original species, so it is a common material for bonsai.

two。 Feather maple (var.dissectum (Thunb.) Maxim.), also known as coir maple, Acer truncatum. The tree is short, with sparsely spreading branches and slightly drooping branches. Leaves 7-11 deep, several lobes to the base, lobes narrow and pinnatifid, very beautiful.

3. Red feather maple (var.dissectumf.ornatum (Carr.) Schwer), also known as red fine leaf Acer. Leaves are purplish red all the year round, and I share the same feather maple.

4. Golden leaf Acer (f.aureumNichols), whose leaves are thin, 7-11-parted, golden yellow. Acer frutescens is produced in the provinces of the middle and lower reaches of the Yangtze River Basin in China, as well as in Shandong and Zhejiang. It's distributed in Japan. It is a common ornamental tree species in the garden, and there are many wild trees in the mountains. Like light, like warm and humid climate, not very cold-resistant, suitable for humus-rich, fertile and moist acidic or neutral soil. Potted plants should be protected from the west and direct sunlight, and should be properly sheltered during the high temperature period in summer.

(2) material selection and cultivation measures

Artificial breeding: generally use sowing method to breed, can also use grafting method. After the Samara was ripe in October, it was sown with picking, or stored in wet sand, and then sowed again in the following spring. The row spacing of strip sowing is about 20 cm, the thickness of covering soil is about 1 cm, and it is covered with straw. If it is sprouted and unearthed in late March, the grass should be uncovered in time. In order to prevent the scorching sun, from July to August, a shed should be built for shading, watering to prevent drought, and thin and rotten cake fertilizer should be applied to promote the growth of seedlings. The seedlings of the same year can be as high as 30cm and 40cm and will be planted separately after leaving the bed for a year. Red maple, feather maple and other ornamental varieties are usually cultured by grafting before sprouting in spring, with 2-3-year-old Acer truncatum seedlings as rootstocks. Splice or ventral connection should be a few centimeters from the ground. After receiving work, the growth is relatively slow, so it is necessary to strengthen management. If the ventral grafting of single bud is carried out in summer, the survival rate is higher and the seedling is faster. Acer maple wild people are mostly tree-shaped, it is not suitable to make bonsai, wild saplings under the forest, dig back potted plants, can be processed into a beautiful ornamental bonsai.

(3) the process of potting.

Selection basin: Acer maple should use shallow oval or rectangular glaze pottery basin, in which the variety of red leaves, it is appropriate to choose gray, light blue, light green, light yellow and other colors, black effect is also very good. Purple, red and other colors can be used for green leaves.

Use soil: Acer davidii likes to be fat and wet, and it is appropriate to use fertile, loose and moist slightly acidic soil or neutral soil. Potted plants can use humus-rich mountain soil or rotten leaf soil.

Planting: can be carried out after defoliation in spring or autumn. When planting, pay attention to make the root system stretch, do not bend in the basin soil. For precious varieties, it is necessary to strengthen management after planting, keep the basin soil moist, place it in a shaded place, and move to a ventilated and transparent place when the growth is exuberant.

(4) Positioning techniques

Processing: Acer chinensis is often modeled with the combination of climbing and pruning. Brown silk should be used for climbing, and it must be removed in time, otherwise it is easy to fall into silk. If you use wire climbing, it is all the more necessary to prevent wire trapping. Climbing and binding processing should be carried out during the plum rain period or after defoliation. The big branch of Acer truncatum can be climbed, while the twig should be trimmed. Generally, each branch is left with 1-2 nodes, and the front end is cut off to make the two side branches into a girl shape. After that, they are pruned in turn, and finally form a crown.

Tree shape: Acer truncatum is suitable for co-planting or jungle type. Isolated planting can be made into oblique dry type, curved dry type and other tree shape. The leaf shape is beautiful, red and colorful, quite beautiful. In the production of co-planting, we should pay attention to the treatment of primary and secondary, density, height, distance, and so on. We can refer to the layout of money pine, which is mostly straight, while Acer maple is often bent, so we should also pay attention to the direction and degree of trunk bending when co-planting, so as to achieve unity and coordination.
