Recently, a flower friend asked Xiaobian what kind of plants are suitable for putting at home, which can not only beautify the environment, but also purify and improve the air? Acer palmatum is a kind of foliage plant, which is a good "four seasons" greening tree species. So what's the breeding method of Acer palmatum? Let's look down together~
Breeding methods of Acer palmatum (basic knowledge): the best breeding time: between May and June or in the middle and late September;
The best growing soil: Acer henryi likes fertilizer and humidity, and it is suitable to use fertile, loose and moist slightly acidic soil or neutral soil. Potted plants can be planted in humus rich mountain soil or rotten leaf soil;
Growth humidity requirements: water should be sprayed frequently at the place where Acer palmatum is placed, and the relative humidity should be kept at 85% - 90%, so as to keep the leaf fresh and the cutting bed moist;
The best growth temperature: Acer palmatum likes to be warm, and it should be moved to the room with room temperature of 0-5 ℃ before winter in North China;
The best growth light: Acer henryi likes the environment of sparse shade, and is afraid of sunlight in summer.
Cultivation method of Acer palmatum
For open field cultivation, organic fertilizer should be applied three times a year to prevent partial application of nitrogen fertilizer, and more phosphorus and potassium fertilizer should be applied, otherwise the leaf color will not be bright.
The potted Acer palmatum usually starts to sprout in spring and applies fertilizer and water once a month, and then changes to potassium fertilizer from September. If 0.5% - 1% potassium sulfate solution or plant ash extract is applied, the leaf color will be bright.
Watering points:
In open field cultivation, attention should be paid to watering in dry weather, and soil loosening and weeding should be carried out frequently to increase soil permeability so as to facilitate root development.
The potted Acer palmatum should be watered enough in the growing season, but not too much, so as to keep the soil moist.
Pruning tips:
Pruning should be combined with shaping after defoliation every winter.
Basin soil replacement:
For Acer palmatum, it is better to use a shallow oval or rectangular glazed pottery basin. For the red leaf variety, it is better to use gray, light blue, light green, light yellow and other colors. The black effect is also very good. The type of green leaves can be purple, red and other colors.
Breeding methods of Acer henryi
Breeding points:
Acer henryi is propagated by seed and grafting. In general, the original seed is propagated by sowing, while the horticultural variety is propagated by grafting.
Seed propagation: the seeds can be sown after harvesting in October, or the seeds can be sown with wet sand until the next spring. After sowing, the soil is covered with 1-2cm soil, watered, covered with straw, and the grass is removed after emergence. The row spacing of drill sowing is 15-20cm, and the sowing rate per mu is 4-5kg. The seedlings are afraid of the sun and need proper shade. The seedling height of the current year is 30-50cm. Transplanting should be carried out in the period of dormancy of fallen leaves. The small seedlings can move with roots exposed, but the large seedlings should move with soil balls.
Grafting propagation: grafting when the rootstock grows most vigorously. The seedlings must be transplanted 2-3 times. Transplanting should be carried out after defoliation and before sprouting. Grafting can be done by cutting, abutting and budding. The stock is usually 3-4-year-old seedlings. Cutting and grafting should be carried out when the rootstock buds expand from March to April in spring. It is better to cut the rootstock at 50-80cm above the ground for high grafting, so that the shoots can be more than 50cm long in the same year. It is difficult to connect, but it is easy to ensure survival.
According to the experience of Nanjing, the best time for budding is between May and June or in the middle and late September. 5. June is the vigorous growth period of rootstock, and the interface is easy to heal. The buds on short branches sprouting in spring are suitable for budding, while the buds on long branches sprouting in summer are suitable for grafting on small rootstock in mid and late September. In autumn, the survival rate can be improved by increasing the grafting position and leaving more stems and leaves. After planting Acer palmatum, it is better to apply quick acting fertilizer 2-3 times in spring and summer, keep the soil moist in summer, and dry in autumn.
Pest control:
We should give priority to prevention by spraying oxamyl or Dimethomorph or Aimiao EC, ningnanmycin, abamectin, lambda cyhalothrin or chlorpyrifos or acetamiprid silicone 3000 times, once every 15-20 days in case of no disease and once every 5-7 days in case of serious disease. Pay attention to alternate medication.
The common insect pests of Acer henryi are grub, mole cricket, scarab, echinacea, aphid, longicorn, borer, black worm and Anoplophora glabripennis.
Grubs, mole crickets and other underground pest control grubs, mole crickets and other gnawing seedling roots and stems, resulting in seedling death. 50% phoxim EC or 48% lesben EC 1000 times can be used, mixed with fine soil, spread or root watering.
Scarab, thorn e, aphid and so on prevent and control the pests of the branches and leaves, scarab, thorn, aphids, spider mite, etc., often eating red maple leaves, resulting in poor growth of seedlings, can be avermectin, fast catching, Omethoate 800~1000 times spray.
The pests such as beetles, borers, and other pests, such as beetles, borers, and so on, are harmful to the branches of Acer trunkum, causing dead branches and even pruning of the Acer trunks. They can be sprayed with 2000~3000 times liquid of fenvalerate, green Kung Fu, or dichlorvos and other pesticides, and sealed with sticky mud.
How to distinguish Acer palmatum from Acer palmatum: 1. Acer palmatum is Acer palmatum, Acer palmatum is not necessarily Acer palmatum
In biological classification, Acer truncatum is also called Acer palmatum, but Acer palmatum is not necessarily "Acer truncatum". Acer palmatum is also known as Acer angustifolia, a Dou Xian and Acer salicifolia.
2. Plant morphology is different
Acer palmatum is generally 6-7 meters high, and it belongs to thin waist and palmatum with 7-9 lobes. Acer palmatum is generally 10 meters high, and it is relatively slender and palmatum with 5-7 lobes. The base of Acer palmatum is heart-shaped, the first end of leaves is caudate, the edge is serrate, and the branches are red. The base of the maple is wedge-shaped or heart-shaped, the leaves are oblong, the top of the leaves is pointed, the edge is serrated, the surface of the leaves is hairy, and the branches are generally green or gray. Acer palmatum may have red leaves all year round, and Acer glauca may have green leaves.
