How to spend the winter in potted daffodils
As a representative of traditional New Year flowers in China, daffodils have become frequent visitors to winter windowsills with their elegant attitude. However, cold weather is always a test for bulbous plants. Only by mastering scientific maintenance methods can Fairy Lingbo survive the winter safely. The three major factors of winter conservation of daffodils are precisely controlled by temperature. Daffodils grow best in an environment of 5-15℃, and the cold tolerance threshold of hydroponics plants is lower. The north needs to move into the indoor south-facing window sill before the first frost, and stay away from glass at night to avoid freezing damage. It is recommended to build a simple greenhouse and cover it with double light-transmitting films to create a miniature greenhouse effect. Scientific management of lighting requires 6 hours of scattered light every day in winter, and the "morning sun and noon shade" method is adopted: full light before 10 a.m. to promote photosynthesis, and gauze curtains are used to filter strong light at noon. Rotate the flowerpot regularly to ensure uniform light reception and avoid excessive stems and leaves that affect the quality of flowering. Dynamic balance of water and fertilizer hydroponics requires changing water every week and drying 24 hours in advance to keep the water temperature consistent with the environment. Soil culture maintains micro-moisture in the substrate, and water is replenished by dipping basin method. Potassium dihydrogen phosphate (concentration of 0.2%) was applied during the budding period, and nitrogen, phosphorus and potassium balanced nutrient solution was used after flowering. Narcissus freeze injury protection system When the temperature continues to fall below-3℃, the roots of hydroponics plants will freeze and die within 48 hours. Emergency treatment needs to transfer frostbitten bulbs to 8℃ environment for natural thawing, remove transparent rotten tissues and soak them with carbendazim. Before the cold wave, the planted plants can be covered with pine needle + pearlite mixed insulation layer.
Through the three-dimensional regulation of temperature, light and water and fertilizer, combined with the cold wave warning mechanism, narcissus can not only survive the winter safely, but also realize the surprise of extending the flowering period by 30%. It is recommended to use a thermometer and fill light to form an intelligent maintenance system to keep the window sill in winter blooming elegant and fragrant.
