Introduction to common propagation methods of sweet-scented osmanthus

Osmanthus fragrans are evergreen shrubs or small trees of the genus Oleaceae. As the sweet-scented osmanthus blossoms, it is very popular, and many people will use it as a food to eat. Interested flower friends will also plant their own sweet-scented osmanthus, the editor will introduce to you the common breeding methods of sweet-scented osmanthus, friends who like sweet-scented osmanthus can understand together.

Osmanthus fragrans

First, sowing and reproduction: as the number of years for sowing and breeding to reach flowering is very long, family flower cultivation generally does not use this kind of method.

Second, striping propagation: striping propagation can be divided into high-pressure propagation and low-pressure propagation, high-pressure propagation is to select 1-2-year-old sturdy branches from the mother tree in spring, select easy-to-bend parts to cut or ring peel, the depth to reach the xylem, and then press into the deep grooves of 3~5cm, and use wood to fix the pressed branches, leaving only the tip and leaves on the outside. Low pressure propagation time is from spring to summer, to select a relatively sturdy low dry mother tree, we must choose a low branching or tufted 1mur2 mother plant, with the high pressure method to cut a circle or ring peeling. In the process of culture, keep the substrate moist all the time, and cut off the mother plant for maintenance after rooting in autumn.

Third, grafting propagation: sweet-scented osmanthus has many methods of grafting, its rootstocks generally choose privet, lobular privet, small wax, water wax, tassel and white wax and so on. Among them, the bonding method is commonly used, and it is often used in potted sweet-scented osmanthus in our country. Its advantages are: long time for grafting, easy to survive, fast forming and early flowering. Therefore, it is generally used to graft sweet-scented osmanthus. First move the scion closer to the rootstock. The branches of sweet-scented osmanthus selected as scions can be close to the branches of rootstocks by means of support, cushion, frame, hanging, binding and so on. Then determine the suitable grafting position of rootstock and scion, and fix the position. Then the interface bevel was cut at the grafting site between the rootstock and the scion. The slope is oval in shape, the length is 3-5cm, and the depth of the slope is generally no more than half of the thickness of the branch. After the grafting and binding is completed, cut off the branches of the rootstock 1 cm above the interface. After grafting, if the branches germinate below the interface of the rootstock, it should be erased in time. Thirty-five days after grafting, the scion was cut off from the interface and separated from the mother. 5 days after cutting the scion, the scion should be checked to see if it has survived. The scion branches and leaves have survived normally; if the leaves have wilted, the grafting has failed.

4. Cutting propagation: before sprouting in spring, the best time is to use annual fully developed branches, cut into 5~10cm long, cut off the lower leaves, leave 2 or 3 green leaves in the L part, insert them in the river sand or loess seedbed, irrigate or spray water in time after planting, and shade, keep the temperature 20: 25 ℃, relative humidity 85% 90%, can take root and transplant after 2 months.

How to raise sweet-scented osmanthus trees, the culture methods and matters needing attention of sweet-scented osmanthus trees

To a certain extent, the development of sweet osmanthus is limited.

The cultivation of sweet-scented osmanthus trees is mostly carried out in early spring. First, dig a big hole in the place where the soil is fertile and sunny, apply some organic fertilizer, at the same time, apply some plant ash, apply fertilizer and water once or twice in July or August, apply rotten compost before winter, apply available nitrogen once in March of the following year, apply available phosphorus and potassium fertilizer again in July, and apply organic fertilizer again in October. At ordinary times, attention should be paid to weeding and watering as well as the prevention and control of diseases and insect pests, which can make sweet-scented osmanthus trees bloom luxuriantly year after year and have a long aroma.
