What is the correct planting method of Osmunda japonica?

The flower language of osmanthus fragrans is spoony love. Lucky, eloquent, female. Osmanthus fragrans has a unique personality. Osmanthus fragrans is also called full house and full meal. Many people are curious about how osmanthus is planted. The following are the planting methods of sweet-scented osmanthus arranged for you, I hope they are useful to you.

Planting techniques of Osmunda japonica

plant

Lagerstroemia indica is drought-tolerant and afraid of waterlogging. Water it once a year before germination in spring and after defoliation in autumn. If it is not too dry at ordinary times, there is no need to water it. Generally, water 1 ~ 3 times in spring drought, and drain well in rainy season to prevent water from rotting roots.

Ground planting: it should be planted after defoliation from June 165438+ 10 to March of the following year. When planting, the trunk height should be 160~ 180 cm, and the upper part should be cut off. After the new spring bamboo shoots grow, we should choose 3~4 main branches with suitable angles to bloom.

Fertilize soil or land

Organic fertilizer can be applied after defoliation in winter and before germination in spring every year, and it is best to apply human excrement or sesame paste residue to make plants grow vigorously and flowers grow big and colorful in the coming year. Generally speaking, the management of Lagerstroemia indica is still relatively extensive. In early March, shoot fertilizer was applied in combination with nitrogen, phosphorus and potassium; in late May and early June, phosphorus and potassium were applied 1 time to strengthen branches and promote flowers; in late July and early September, flowering fertilizer 1 time was applied respectively to make flowers bloom brightly.

decrease

In order to make Osmunda bloom, pruning should be carried out during dormancy. Because the inflorescence of Lagerstroemia indica is planted at the top of the new branches of the year, the annual branches should be pruned and retracted when pruning, so that the nutrients are relatively concentrated and the branches are strong. Long branches, dead branches, drooping branches, pests and diseases branches, slender branches and endogenous branches should be cut off, and the side branches at the lower part of the trunk should be cut off in time during the young tree period, so that the upper part of the trunk can obtain sufficient nutrients and form a good crown. The flowers of Lagerstroemia indica grow at the top of the spring shoots that germinated that year, with strong germination and irregular crown, which needs pruning. In order to ensure normal flowering and form large inflorescences, pruning in winter is very important. Growers on the ground should cut off the branches of the current year at the height of the main branches, so that the robust branches can blossom in the next year. Pruning of Lagerstroemia indica is mainly in dormant period, supplemented by growing season, and different pruning methods are adopted according to different garden environments.

(1) Natural happiness: Before Lagerstroemia indica leaves the garden, 3 ~ 5 big branches can be selected as main branches, and 1 ~ 2 branches with different angles and balanced growth can be selected as side branches. When pruning every year, the upper branches with larger angles should be selected as extension branches and pruned appropriately. This kind of tree has good permeability and can blossom in three dimensions.

(2) Layered trunk: This kind of tree needs obvious trunk and main branches. The trunk is layered and the main branches are evenly distributed on the trunk. Generally, there are about 4 main branches, and 2 left and right side branches are left on the main branch. This tree shape is suitable for garden cultivation and solitary tree planting.

(3) Controlling flowering and pruning: Let Wei Zi be there? Eleven? In full bloom, the new shoots of Lagerstroemia indica can be cut short in early August, and all the branches and leaves at the tip of the flower branch can be cut off by about 1/3. After that, strengthen the management of water and fertilizer, apply fertilizer for 2 ~ 3 times, and flower buds can form again on the new shoots in about 30 days. Generally, it can bloom again in about 50 days from the date of cutting short, adding a festive atmosphere to the festival.

Different pruning methods should be adopted in different garden environments. Pruned Lagerstroemia indica trees are beautiful, natural and colorful. In the garden, if matched with Qiu Shu, it is an excellent tree species to decorate autumn scenery. Planting Lagerstroemia indica in a natural and happy form in Chi Pan and the riverside will have the scenic interest of "flowers in the pool are low and water is small, and flowers in the heart of the pool are light" (from "Li Taishe hits Hong Wei drunk on the pool"); If placed in front of evergreen trees, red flowers will be more beautiful and moving in the green leaves.

The value of osmanthus fragrans

Low-grade trees for roads or gardens

Tree species used as street trees are relatively simple in greening function, and there are even fewer characteristic tree species such as Lagerstroemia indica, which not only meets the basic requirements of street trees for shading, dust retention, noise reduction and absorption of toxic gases, but also has beautiful posture and bright colors. Therefore, Lagerstroemia indica as a street tree will have a broad market for technical development and promotion (there have been successful cases of small street trees in the United States). However, street trees have certain requirements for trunk height (generally, the lowest branch height is more than 2.0m above the ground), while Lagerstroemia indica usually has low branching points, strong lateral bud germination and relatively weak trunk polarity, so the technical difficulty to be solved as a street tree is to cultivate trunk. The author recommends the following three methods to solve this problem: 1, cutting off strong buds or changing heads; 2. Dry cutting method; 3. Repeatedly short side branches to promote the central trunk.

Garden solitary tree

The single planting of trees is mainly to show the physical beauty of trees, and can be independently landscaped for viewing. As an exclusive tree species, it is generally required to have a beautiful tree shape, a tall or strange trunk shape and a long life. The biggest advantage of Lagerstroemia indica as an ornamental tree species lies in its stretched posture, lush foliage and lush flowers; But the main question is how to achieve it. Qiao Hua? It is required to work hard on the dry shape and crown shape in order to fully reflect its ornamental value.

Landscape tree

The garden trees we talk about here have a wide meaning: they refer to all the garden trees that are applied to roadsides, pools, mounds, corridors, front and back houses, or matched with rock buildings, or scattered in groups of 30 to 50 trees in some small scenic spots, thus forming a natural and interesting layout. Most of them have unique ornamental characteristics in branches, flowers, fruits, leaf color or leaf shape, which can be well coordinated with the surrounding environment in garden application and create beautiful scenery. When Lagerstroemia indica is used as a landscape tree, we should fully consider the differences of application places in order to choose different styles to match it. Here we recommend several kinds, such as cup-shaped, happy-shaped, cluster-shaped, combined group plants, pavilions, vases, flower baskets, archways, animals and even geometric shapes.

Bonsai modeling tree

Bonsai is not only a potted plant confined to indoor viewing, but also applied to parks, botanical gardens, squares and even residential areas for various sketches. Ziwei has always been a very good bonsai tree material, which is a pile view. Eighteen bachelors? One; Among the eight traditional schools of pile scenery, Huizhou School and Sichuan School are widely used. To sum up, it has various shapes, such as bending, cross-bending, bending-dry, dry-type, twisting-type, screen-type and Youlong-type. Therefore, another important garden landscape use of Lagerstroemia indica can also be equipped with various pile landscape shapes in a suitable environment to achieve a rich, simple, elegant and finishing touch effect.

Drug action tree

Lagerstroemia indica also has medicinal effects, which can be described as a treasure all over. First of all, the seeds of Lagerstroemia indica can be used as pesticides to kill pests; Secondly, crape myrtle leaves can cure white dysentery, flowers can cure postpartum hemorrhage, and children's rotten head and fetal poison can cure carbuncle and swollen sores. Taking root and bark as medicine can promote blood circulation, stop bleeding, detoxify and reduce swelling. Used for various bleeding, fracture, mastitis, eczema, hepatitis, ascites due to liver cirrhosis, etc.

The legend of osmanthus

Legend has it that if your home is full of Wei Zihua, Wei Zixian will take care of you and give you a lifetime of happiness. There is a legend about the origin of Osmunda japonica in China. It is said that there was a fierce beast called Nian in ancient times, which hurt countless people and animals, so Zixing descended to earth, locked it in the mountains and allowed it to go out only once a year. In order to supervise this year, Ziweixing became Wei Zihua and stayed in the world, bringing peace and beauty to the world.

Cultivation method of Osmunda japonica

Cultivation management

Lagerstroemia indica should be planted in the leeward and sunny place with deep soil layer, fertile soil and good drainage. Large seedlings should be transplanted with soil balls and properly trimmed branches, otherwise the survival rate is low. Apply decomposed organic fertilizer as base fertilizer in the planting hole, water it after cutting, and water it 1 time after 3 days. Lagerstroemia indica germinates late. Under normal circumstances, the leaves will only spread from mid-April to the end of April. Because of root injury, the germination of new plants will be delayed. So don't give up management just because you have no job.

After survival, the plant management is extensive, Lagerstroemia indica grows vigorously, is easy to cultivate, and has low requirements for soil, but it grows best when planted in deep and fertile sandy loam. Sex likes light, so it should be planted in the lee of the sun or under the roots of the south wall of the courtyard. If the light is insufficient, plants will not only spend less or not, but even grow weak and have small branches and leaves. Lagerstroemia indica is cold-resistant, but it should be well protected from cold and heat at seedling stage, and the adult plants over three years old do not need heat preservation. Lagerstroemia indica is drought-tolerant and afraid of waterlogging. Water it once a year before germination in spring and after defoliation in autumn. If it is not too dry at ordinary times, there is no need to water it. Generally, water l ~ 3 times in spring drought, and drain well in rainy season to prevent water from rotting roots. Autumn is not suitable for watering. Fertilization can be applied after defoliation in winter and before germination in spring every year, such as applying human manure or sesame paste residue, which can make plants grow vigorously and flowers big and colorful in the coming year. In order to make Osmunda bloom, pruning should be carried out during dormancy. Because the crape myrtle inflorescence is planted at the top of the new branches in that year, the annual branches should be pruned and retracted when pruning, so that the nutrients are concentrated and the branches are strong. Long branches, dead branches, drooping branches, pests and diseases branches, slender branches and endogenous branches should be cut off, and the side branches at the lower part of the trunk should be cut off in time during the young tree period, so that the upper part of the trunk can get enough nutrients and form a good crown.

Lagerstroemia indica cultivation and management are extensive, but it is necessary to cut off dead branches, pests and diseases in time and burn them. In order to prolong the flowering period, the branches that have blossomed should be cut off in time so as to germinate again and grow the next round of flowers. In order to make the trunk thicker, you can cut off many flowers and concentrate on cultivating the trunk. Practice has proved that Lagerstroemia indica can bloom many times a year as long as it is properly managed, as long as 100 ~ 120 days.

Tillage and sowing

The seedlings of Lagerstroemia indica are planted with multi-tiller seedlings, and the root tiller seedlings can be transplanted from the tiller seedlings of wild shrubs, or fresh and robust seed roots can be harvested and buried (the length can be determined according to the thickness of the seed roots), and the planting time can be selected in early spring.

Attention should be paid to seed collection, seed storage and moisture preservation in the field when sowing and raising seedlings of Lagerstroemia indica. Seeds are usually collected in September-10, and when the fruit turns from green to brown, the seeds are cut, fried and kneaded. We should seize the opportunity to collect seeds. Seeds are immature too early, and naturally fall off or dry up too late.

Sow first, because the seeds are as big as smoke seeds. Sow like? Smoke seedlings? Bed soil should be fine, sowing should be even (with sand), covered with fine soil and covered with straw to preserve moisture. When Lagerstroemia indica seedlings germinate, the straw should be pulled out in time, but attention should also be paid to keeping the seedbed moist.

In early April, select the excellent seeds collected in the previous year. Before sowing, you can soak the seeds in warm water or cold water at 40℃ to make them absorb water. Then, shallow furrows are opened on the prepared border according to the row spacing of 30 cm, and seeds are sown in the furrows, and the dosage per mu is 14? 20 kg, lightly covered with soil after sowing, with a thickness of 0.5? 1 cm, slightly depressed. At 20℃, generally 15? Buds can germinate within 20 days.

When the seedlings grow to 3 cm, the first thinning is carried out in combination with weeding, mainly to remove the pile of seedlings and improve the ventilation and light transmission conditions. When the height of the seedlings is 5cm, the second thinning is carried out, and the plant spacing is 10? 15 cm seedlings, about 3000 plants per mu. 6? August is the fast-growing period of Lagerstroemia indica. Combined with watering, apply 40kg of three-element compound fertilizer of nitrogen, phosphorus and potassium per mu, so as to apply less and more, and apply fertilizer three times. It rains for a long time and should be drained in time to prevent waterlogging. Combined with weeding and intertillage 3? Four times. When aphids or yellow thorn moths harm seedlings, 2.5% enemies can kill 2000? 3000 times solution or 50% parathion control; If powdery mildew occurs, 70% thiophanate-methyl can be used to control it. Under this management, Lagerstroemia indica seedlings can reach 60 cm in that year.
