Daffodil is a famous indoor ornamental flower, and it can control the flowering period at will, so it is deeply loved by people. How to control the flowering period of daffodils just on New Year's Day or the Spring Festival? Add a festive atmosphere to the festival. Master the time of bulb immersion at room temperature 8 °C-12 °C in winter, narcissus from soaking to flowering for 40 days, room temperature at 15 °C, 28 days to 30 days, room temperature at 18 °C-22 °C only 23 days -25 days It is flowering, so the date of soaking the bulbs in advance can be calculated according to the temperature of the house. For example, the room temperature of the house is about 15 °C. If you want to bloom on New Year's Day, you can soak it on November 30. Next year's Spring Festival is January 24th. To make the Narcissus Spring Festival bloom, it should be soaked on December 24. Soaking method Before the water is raised, the narcissus bulb should be stripped of the brown outer skin, and then a small knife is used to draw two knives from the center of the bulbus in the middle of the bulge. The depth is not more than 1/3 of the diameter of the ball to avoid damage to the flower bud. After cutting, gently squeeze by hand to increase the gap is conducive to the extraction of the leaves and flowers. Soak the bulbs in clean water for one day, remove the mucus, then place them in a shallow water basin, fix them with stone eggs or thin ropes, and then inject them into clear water for conservation. Change the water and fertilizer to change the water every one or two days. If the pot water is poured out at night, then inject new water in the morning, you can restrain the leaves from growing and prevent the leaves from hiding. Water-fed narcissus is usually not fertilized, but the appropriate application of phosphorus and potassium fertilizer can make the leaves thick and green, with large flowers and rich aroma. Therefore, when changing water, 1 g of potassium dihydrogen phosphate is added to each pot, which is very effective. If the seedlings and daffodils are cultivated under the conditions of weak indoor light and high temperature, there will often be defects such as long leaves, small flower patterns and short flowering period, and even the whole plant will be affected, which will affect the ornamental value. For this reason, the narcissus pot must be placed indoors in the sunny place before the flower buds are released. In the windless weather, when the outdoor temperature is above 0 °C, the narcissus pot should be placed in the outdoor sunlight to receive direct sunlight, which is conducive to seedlings (ie, dwarfing) and prevent the blade from growing taller. It is best to place it at a lower temperature (8 ° C - 10 ° C) at night. Low temperatures at night can also contribute to dwarfing. Don't put the narcissus pot near the radiator, otherwise it will grow wild and the pattern will become smaller. However, sunlight should be avoided after flowering to prolong the flowering period.
