Cutting Propagation method of Osmanthus fragrans

1. Cutting time

The best time is before the spring bud sprouts, during this period, the branches are rich in hormones, nutrients accumulate, the temperature rises after insertion, and the cuttings quickly produce healing tissue. If the opportunity is missed, the flower buds and autumn shoots can be cut from late July to mid-August before the spring shoots stop growing, but the shoots that germinate and grow in spring must be selected as cuttings in order to achieve the ideal survival rate.

Second, prepare to insert the bed.

When cutting, choose a sunny place, dig a flat-bottomed rectangular pit with a length of 12 meters, a width of 1.2 meters and a depth of 0.7 meters, and fill the bottom with a dung storage layer of 40 cm, or other heat-generating materials, and cover it with a layer of vermiculite and perlite of 15 cents and 20 centimeters, as the cutting substrate of the seedbed. After cutting, build a small plastic arch shed with a height of 50 centimeters and an Arbor with a height of 1 meter. After the seedbed is done, the soil is strictly disinfected with 0.5% potassium permanganate aqueous solution to prevent the occurrence of seedling blight and rot.

3. Cutting operation

When cutting, select the robust annual autumn shoots without diseases and insect pests as cuttings, cut and grow 8mur10 cm, retain the top 2 Mel 3 leaves, and then soak the cuttings at 2 cm at the base of 2 cm with 0.05% UV 0.1% naphthalene acetic acid solution for about 5 seconds, with cutting, dipping and cutting. At the time of insertion, according to the row spacing of 10 × 10 cm plants, first make a small hole with a wood (bamboo) stick, insert the cuttings, cover the substrate and then lightly compact, pour water with a fine hole spray pot, and then cover the film and grass curtain awning. The cutting method in autumn is the same as that in spring, but the temperature should be specially controlled so as not to affect the survival.

Cutting Propagation of Osmanthus fragrans

The cultivation of red-backed sweet-scented osmanthus (detailed introduction) is not difficult, but because of its high ornamental value, it is often made into pot culture and is very popular, so it is in great demand. Now, sweet-scented osmanthus often uses cutting methods to quickly raise seedlings to meet the needs of the market.

Temperature of Culture method of Osmanthus fragrans

Osmanthus fragrans is a subtropical plant, which is not cold-tolerant. The suitable temperature for growth is between 15-25 ℃, and the overwintering temperature should be not less than 5 ℃.

Light

Resistant to semi-shade, like scattered light, avoid strong light exposure, summer needs to be placed in a shaded and ventilated place, which is conducive to keeping the red back sweet-scented osmanthus leaf color thick green.

Watering

Red back sweet-scented osmanthus likes the moist growth environment, but avoid waterlogging. Fully watered during the growing period, keep the basin soil and the surrounding environment moist, but pay attention to avoid stagnant water. Control watering in winter, generally watering every 7-10 days, basin soil is slightly wet and dry.

Fertilizer application

When planting or turning the basin and changing the soil, some compound fertilizer can be applied as the base fertilizer, the compound fertilizer containing nitrogen, phosphorus and potassium can be applied once in the growing period, and 0.2% potassium dihydrogen phosphate solution can be sprayed twice during flowering. Fertilizers are not needed in midsummer and winter.

Soil

Like fertile, loose, well-drained sandy loam.

Reproduction method

Two propagation methods of root division and cuttage can be adopted. The root splitting method is generally carried out in March or April of each year, and 2-3-year-old seedlings are selected for planting. The most common is cuttage propagation, select annual strong branches as cuttings, cut into every three segments into plain soil, about 23 cm deep, shade and moisturizing about two months can take root.
