Magnolia commonly known as Magnolia, Magnoliaceae, is a deciduous tree, is a good tree species gardening. Magnolia is hi light and shade-tolerant, and it has strong cold resistance. It is good for fertile, humid, and well-fed neutral or acidic soils. Due to the low survival rate of cutting propagation of magnolia, the use of seedling grafting for reproduction is mostly used in production. The specific methods are as follows: 1. Seed harvesting is conducted every year from September to October. When the tip of the magnolia fruit is cracked, it is harvested and placed in a cool, ventilated place. After 3 to 5 days, when most of the fruits are cracked, the seeds are peeled off. Soak the seed in water for 3 to 5 days. After the red seed coat becomes soft, rub and remove the impurities to obtain black or brown seeds. Finally, put the seeds in a cool and dry place. The seed is mildewed. Second, the treatment of sand magnolia seeds have a longer dormancy period, the need for sand processing. The method is: in November to December, dry seeds and sand in a ratio of 1:2, or in a flower pot or other air-permeable container by a layer of seed and sand in a greenhouse. ~ 4 months. It is advisable to keep it moist during sand traps. In the spring of March and April of the following year, the best sowing date is when the hard seed coat is cracked and the white seed embryos are exposed. Third, sowing seeding to take the ditch seeding method, the seed spacing is about 1 cm. After sowing, cover 1 centimeter of loose fertile soil and appropriate shade to keep the soil moist and not compact. Seedlings began to emerge about 7 days after sowing, and seedlings could be released about 15 days later. Fourth, Grafting When the height of the seedlings is 30 cm or more and the base diameter of the stems is more than 0.7 cm, grafting can be carried out using rootstocks. The best grafting period is from August to September. When grafting, select the buds from the old Magnolia tree which were born in the year and have been on the lignified shoots, attached to the stems of the Magnolia seedlings, and then wrapped with a film to wrap; in the spring of the next year, go to the old film band, and place the scion upwards by more than 30 cm. Cut off? Grafting seedlings can bloom in June of that year. The number of flowering plants and the number of calyx formation in the general high grafted seedlings were significantly higher than those of low grafted ones. China Agricultural Network Editor
