Common seeds, such as the seeds of sea bream and impatiens, can be sown directly without treatment. Where seeds have oil wax seeds, such as magnolia can be used to plant seed ash by adding water into a paste. Lotus, canna and other seed coats are harder, and seed coats need to be contused before sowing and soaked in warm water for 24 hours before sowing. The seeds of eucalyptus leaves are sowed before freezing in winter, and are irrigated with water. The seeds of winter seeds are cracked and germinated every two springs. All kinds of seeds need to be tested before germination, usually 100 seeds, soaked in warm water and placed in a container moistened with gauze, germination at a temperature of about 22 °C, test the seed germination rate, in order to determine the sowing the amount. For woody flowers with thick seed coats, the buds must be destroyed before spring so as to facilitate seedlings to grow quickly and neatly, with high seedlings. Pregerminating methods such as flooding and stratification are used. (1) Flooding and germination. Three kinds of water temperature can be used to deal with: First, cold water soaking germination, water temperature above 0 °C, suitable for thin seeds of seeds, such as wisteria, palm, waxy, cedar and so on. The second is soaking in warm water, germination, water temperature 40 °C ~ 60 °C, suitable for thicker species of peony, peony, red citron, Feng Yang, Chinese wolfberry, Platycladus orientalis, larch and so on. The third is hot water soaking germination, water temperature 70 °C ~ 90 °C, apply to the seed coat hard seeds, such as acacia, acacia, eucalyptus and so on. When soaking, the amount of water used is about 3 times that of the seeds. When pouring into the water, stir it to make the seeds evenly heated. When soaking with hot water, after the water temperature drops to Natural temperature, stop stirring and soak for 13 days. After the seeds are swollen, remove and put germination at a temperature of 18°C～25°C, and rinse with warm water 1 or 2 times a day. Pay attention to gently turning until the seed breaks and sow. (2) Lamination accumulates. The so-called stratification and pregermination is performed by moisturizing and refrigerating at a temperature of 0°C to 7°C°C after mixing three parts of wet sand and one seed. Magnolia grandiflora, Michelia, Magnolia, Lonicerae, and seeds that germinate every other year require stratification and germination. Here, for long-term dormant seeds or seeds that have budding every other year, variable temperature and accelerating methods can be adopted, ie, maintaining the temperature between 25°C and 30°C during the day after soaking, and the temperature around 15°C at night, repeated for about 10 to 20 days to promote germination. . Such as osmanthus, holly, coral trees, etc., can use this method.
