How to propagate with tender wood cuttings of Osmanthus fragrans

Sweet-scented osmanthus belongs to the evergreen tree of Melilotus family. Its branches and leaves are dark green and graceful. It is fragrant and fragrant when it blossoms. It can not only enjoy the flowers, but also can eat and extract flavors. It has high ornamental and economic value. Sweet-scented osmanthus has few seeds and is difficult to obtain, so it uses cuttings to propagate seedlings, in which tender wood cuttings are easy to obtain, easy to operate and high survival rate. The main technical points are as follows: first, the cutting time should be from mid-May to mid-July and from mid-September to mid-October. At this time, the new shoot has stopped growing, the branch has more nutrients, its meristem meristem has strong meristem ability, and the temperature is suitable, so it is easy to take root and survive after cutting. Second, the bed insertion preparation should choose light loam farmland for deep ploughing to make beds. Require bed width 120 cm, bed height 25 cm, channel width 40 cm, to achieve fine broken soil, flat bed, smooth channel. A plastic film arch shed 50 cm high from the bed surface is built above the slotting bed, and a shade shed with a height of 1.8 meters from the bed surface and 30% light transmittance is built on it. Third, cuttings are collected and selected to grow vigorously, and the excellent plant without diseases and insect pests is the mother tree of cuttings. Cut the semi-lignified shoots from the upper part of the periphery as cuttings. The harvested ear strips should be graded and tied into small handfuls, and the base should be wrapped with wet toilet paper and brought back to the room for treatment. Fourth, the cuttings were cut into 8 cm long and 10 cm long, and the upper part retained 2 leaves that had been cut off in half. The upper end is cut into a flat mouth, the base is cut into an oblique mouth, and tied into a small handle, then the base 3 cm is immersed in 5/100000 naphthalene acetic acid or 1/10000 No. 1 ABT rooting powder solution, and the cuttings can be taken out after 1 hour. 5. Cuttings should be divided into beds (sections) according to diameter grade. With a plant row spacing of 5 × 10 cm, the cuttings were pierced with wooden sticks as thick as cuttings, and then the 2 prime 3 of the cuttings was inserted into the hole to press the soil around the cuttings. Finally, the inserting bed was watered with 10,000 times carbendazim solution to disinfect the soil and keep moisture by water supply. Sixth, after insertion management water spray and shade shed film without water droplets and dry on the bed, should spray water to moisturize. The morning cover of the high-rise shade shed was uncovered at night, the relative humidity in the film shed was kept above 85%, and the temperature was controlled between 18 ℃ and 28 ℃. If the temperature is too high and the humidity is too low, it can be adjusted by removing the cover and increasing water spraying. If the temperature is too low and the humidity is too high, it can be controlled by sealing greenhouse film and reducing water spraying. Spray combined with loose soil spray, spray 2000 times carbendazim solution every 7 days to prevent cuttings from infecting bacteria and causing cortical rot. The soil should be ploughed and planted frequently to maintain the permeability of the bed soil and prevent the young roots of cuttings from rotting due to lack of oxygen. Sprouting and fertilization must timely erase the sprouts at the base of the cuttings in order to reduce nutrient consumption. Combined with water spraying, 0.2% urea or potassium dihydrogen phosphate solution was sprayed every 10 days to promote cuttings root and shoot growth. Dismantling and transplanting summer seedlings can remove the shade shed in October, and the next spring seedlings can be transplanted to field nurseries. Autumn seedlings can be removed from the shade shed in the following spring and transplanted to field nurseries in early summer. Both summer and autumn seedlings can stay in bed for one year, and can be planted out of the nursery when the seedlings are 30-50 cm high in the following winter.
