How do sweet-scented osmanthus trees sow and raise seedlings?

How do sweet-scented osmanthus trees sow and raise seedlings? Please guide sweet-scented osmanthus generally to use cutting to raise seedlings, and single-stem sweet-scented osmanthus to use sowing to raise seedlings, now introduced as follows: 1. The sweet-scented osmanthus blossoms from September to October and the fruit ripens from late March to late April the following year. When the fruit enters the ripening stage and the pericarp changes from green to purplish black gradually, it can be collected. The collected fruits were piled up for about 3 days. After the peel was softened, the pericarp was soaked and scrubbed, the peel and pulp were removed, and the pure seeds were obtained and slightly dried and moist. Because sweet-scented osmanthus seeds have post-ripening period, it usually takes 8 months for sweet-scented osmanthus seeds to germinate. two。 The method of sowing and raising seedlings is commonly used in raising seedlings. A large number of sweet-scented osmanthus seedlings can be obtained by sowing and raising seedlings, which is suitable to be used as street trees. Sowing commonly used wide strip sowing, row spacing of 20 to 25 cm, width of 10 to 12 cm, 20 kg per mu of sowing, per mu of sweet-scented osmanthus seedlings 2.5 to 30,000. Before sowing, put the navel to one side, cover one or two centimeters of fine soil, cover with a thin layer of straw, and spray water until the soil is soaked to prevent soil consolidation and reduce water evaporation. When the seeds germinated and unearthed, uncover the grass in time and put the grass between the rows, which can not only keep the soil moist, but also prevent the growth of weeds. 3. Maintenance technology (1) weeding in ploughing focuses on loosening soil and weeding in a tree plate with a diameter of 1 meter with the trunk as the center. After irrigation or rainfall, ploughing and loosening the soil is carried out to prevent soil consolidation. (2) the watering and drainage of sweet-scented osmanthus is mainly within one month after the new planting and in the summer of the year. Newly planted sweet-scented osmanthus must be watered and conditionally sprayed with water on the crown of the plant to maintain a certain amount of air humidity. Osmanthus fragrans is not tolerant to waterlogging, timely drainage or transplanting waterlogged plants, and adding a certain amount of sand planting can promote the growth of new roots. (3) rational fertilization should be based on the principle of frequent application of thin fertilizer, mainly available nitrogen fertilizer, and medium and large seedlings should be fertilized three or four times a year. Organic fertilizer was applied in the tree plate in early spring to promote the growth of spring shoots. Inorganic fertilizer or garbage fertilizer should be applied in the early stage of winter. In the meantime, fertilizers can be applied once or twice according to the growth of sweet-scented osmanthus. For newly transplanted sweet-scented osmanthus, topdressing should not be too early. The base fertilizer of the transplanting pit should be mixed with the soil and then covered with soil. (4) shaping and pruning ① peel off the useless buds in the lower part of the trunk during sprouting. ② thinning branches to maintain a certain height under the branches, cut off useless branches, generally sweet-scented osmanthus branches after the height of about 1.5m. ③ cut off the long top branches to keep the sweet-scented osmanthus at a height of about 3.5m and a crown width of 2.5m to 3m.
