The plants of Strelitzia reginae Aiton are pollinated by hummingbirds weighing only 2 grams, and are typical bird-like plants. Strelitzia reginae Aiton must be artificially assisted in pollination under the general cultivation conditions in China to form seeds. Plants with upright plant types, strong petioles, rounded and blunt leaf tips, and thick leaves should be selected for seed collection. Before sowing, select seeds that are large and plump, have smooth seed coats, are fresh, have no damage, and are free of pests and diseases. Soak the seeds in 30-40°C warm water for 4-5 days, and then disinfect with 5% Negeran 1000 times solution for 5 minutes. In addition, 500 times solution of 0.3% potassium permanganate or carbendazim WP can be used to soak Strelitzia reginae Aiton seeds for 2 hours, and then soak them in 30-40℃ warm water for 3-4 days. Change the water once a day to facilitate germination. You can also use fine sandpaper to lightly rub the seed skin to accelerate its water absorption and germination, but care should be taken to avoid wiping off the internal white nutrients. The sowing time of Strelitzia reginae Aiton is from May to July. Use on-demand, cover 1-1.5 cm of soil, cover with plastic film after watering, keep warm and keep moisture. The suitable temperature for germination is 25-30℃, and it can germinate 15-20 days after sowing, and unearthed one after another. Increase light after emergence. After the true leaves are grown, the main roots begin to grow downward, which is the best time for transplantation. Transplant the seedlings with soil to prevent root damage. After transplanting, the seedlings should not be exposed to strong light and need to be shaded. When 2 true leaves grow, lightly apply thin fertilizer. Seedlings are planted in pots when they are about 15 cm high. The suitable temperature for the growth of seedlings is 15-25℃, and the room temperature in winter is kept above 8℃.
