Cultivation skills of bonsai production

Sweet-scented osmanthus bonsai cultivation techniques: sweet-scented osmanthus is warm and moist. The average temperature of sweet-scented osmanthus cultivation is 14: 28 ℃, the average temperature in July is 24: 28 ℃, the average temperature in January is more than 0 ℃, the lowest temperature is-13 ℃, and the optimum growth temperature is 15-28 ℃. Humidity is extremely important to the growth and development of sweet-scented osmanthus, requiring an average annual humidity of 75%-85% and an annual precipitation of about 1000 mm, especially when young and adult trees blossom, which will affect flowering in case of drought. strong sunshine and shade are harmful to its growth and generally require 6-8 hours of light every day.

Selection and cultivation measures of Osmanthus Osmanthus Bonsai

Artificial propagation: sweet-scented osmanthus can be propagated by sowing, cutting, grafting, striping and other methods. Cutting and grafting are usually the main methods, while sowing methods are seldom used. The cuttage method uses the softwood cuttings grown in the same year in the plum rain season, and the survival rate is high. Cuttings should be cut from 10-year-old sweet-scented osmanthus with a length of 8 cm to 10 cm and a thickness of 0.3 cm to 0.5 cm, with top tips removed and 2 leaves retained. Soak in naphthalene acetic acid 100ppm solution for several hours before insertion, insert it into the tile basin or seedling bed of sandy loam, the depth of 1B2~2B3, should not be too deep, too deep will lead to poor ventilation and easy to rot roots. After insertion, use your fingers to compact the soil, water through, and timely shade, maintain a certain humidity, often spray foliar water, soil moisture should not be too much. After about 60 days, it can take root. After rooting, it can be transparent in the morning and evening, increase the light time after autumn, in order to promote growth, and can be cultivated in pot in the following spring.

Osmanthus bonsai grafting method generally uses branch grafting, branch grafting has cutting grafting, split grafting and leaning grafting and other methods. Lobular privet, wax, privet and other tree species are commonly used as rootstocks. The cutting method is widely used. When grafting, cut the rootstock 5 cm above the ground, choose the smooth side of the bark, cut vertically with xylem and cut into a cut 2 cm to 3 cm deep. The scion takes an annual mature branch, 6 cm long, with 2 cm 3 nodes, and the lower end of the scion is cut into an oblique cutting plane of 2 cm, and then obliquely cut into a short cutting surface of about 1 cm on the opposite side. Then, the long cutting surface of the scion is close to the cutting surface of the rootstock, inserted into the incision, so that the cambium of the two cutting surfaces are closely connected, and then the cortex of the cut of the rootstock is wrapped on the outside of the scion, bound and fixed with plastic film, and the incision of the rootstock and the top of the scion are closed to prevent water evaporation, and it is easy to survive. The support grafting is to cut off the xylem of the female parent branch of the scion and the female parent branch of the rootstock, which is 5 cm in length and 10 cm in length and 1B3~1B2 in dry diameter, then combine them with each other, bind them with plastic film tape, and then separate them after survival. Depending on the survival is very sure, garden nursery cultivation of potted cassia mostly use this method. The strip pressing method is also often used, and it is easy to survive.

Pot-up process

Selection of pots: sweet-scented osmanthus green leaves and yellow flowers, evergreen all the year round, it is appropriate to choose a deeper round basin or square basin, the diameter of the basin mouth is roughly the same as the diameter of sweet-scented osmanthus branches and leaves, it is beneficial to root development and growth. The texture of the basin is better with purple sand pottery basin or glazed pottery basin. The color is better with purple or ochre, which can be in sharp contrast with the color of flowers and leaves to increase its ornamental effect.

Use soil: sweet-scented osmanthus likes fertilizer, it is suitable to use sandy loam with loose fertility and good drainage. The culture soil of potted sweet-scented osmanthus is usually made of pastoral soil, barnyard manure and river sand 1B3. Attention should be paid to disinfection so as not to infect diseases and insect pests.

Sweet-scented osmanthus cultivation techniques: sweet-scented osmanthus should be planted in early spring or autumn. Before putting on the basin, put a layer of river sand or vermiculite on the bottom of the basin to facilitate ventilation and drainage, and then cover it with a layer of peat soil or fine mud about 2-3 cm thick, up to the depth of the basin 1B3. Then, put the sweet-scented osmanthus seedlings with soil balls in the roots into the basin, obstruct the soil to cultivate the soil, press it with your fingers, and fill the soil close to the mouth of the basin. The soil surface should be 2-3 cm lower than the mouth of the basin, so as to facilitate watering and fertilization. After planting, it should be watered thoroughly, then moved to the shade for about 10 days, so that its "basin", gradually restore growth.

Pose shaping technique

Processing: sweet-scented osmanthus has strong germination and resistance to pruning. After potting in 2012, it will be processed and modeled after blooming in Meiyu season or autumn, and the combination of climbing and pruning will be adopted. The trunk can be truncated into a curved trunk or oblique trunk; those with a higher trunk can be properly cut to make the base sprout new branches without emptiness in the lower part, or re-cut the upper branches and over-dense branches to stimulate new branches in the lower part of the trunk, maintain the balance between the upper and lower parts, and make the tree beautiful and luxuriant.

Tree shape: sweet-scented osmanthus is best made into curved dry type, oblique dry type or floating type. The tree is oblique, with luxuriant branches and leaves, simple and natural, the most enjoyable. When it blossoms, the fragrance is overflowing and refreshing.
