How to make water lilies bloom
As an elegant representative of aquatic plants, water lilies attract many gardening enthusiasts with their unique flowering characteristics. To make water lilies bloom charming flowers, we need to master key elements such as water quality control, temperature management, and light supply. This article will systematically analyze the growth code of water lilies from daily maintenance to flowering rules. Water lily flowering maintenance techniques Water quality management points Maintaining a constant water depth of 25-30cm is the gold standard for water lily growth. It is recommended to replace 1/3 of the water volume every 7-10 days. When evaporation is rapid in summer, the water level needs to be observed every day. Using tap water that has been dried for 2 days can avoid chlorine damage. Special attention should be paid to the transparency of water bodies. When there are signs of algae proliferation, algae-eating fish can be put in for ecological regulation. Temperature control strategy Water lilies have the highest flowering efficiency in the range of 25-30℃, and the temperature difference between day and night is better controlled within 5℃. It is recommended to use a constant temperature hydroponic system in the northern region, and a sunshade net can be built to reduce the water temperature during high temperatures in the south. In winter, it is necessary to keep the water temperature not lower than 10 ° C, and the container can be moved to the indoor sun room for maintenance. The light supply plan should ensure direct light for more than 6 hours per day, and the south-facing balcony or open-air pool is the ideal cultivation position. Using the rotary potted method to adjust 180 degrees every 3 days can allow the plants to receive even light. In continuous rainy weather, it is recommended to use a full-spectrum plant fill light to fill light for 4 hours a day. Scientific fertilization method The application of nutrient solution should follow the principle of "thin fertilizer and frequent application", and special hydroponic fertilizer should be added once every half month during the adult plant period. It is recommended to use slow-release formula for solid fertilizers, wrapped in non-woven bags and hung near the roots. When applying phosphorus and potassium fertilizers in the early stage of flowering, you can use foliar spraying potassium dihydrogen phosphate solution. Water lily flowering time is regular, daily opening and closing mechanism. Flowers usually open gradually at 12 o'clock in the afternoon as the light increases, and reach a fully stretched state at 15-16 o'clock. The closing operation starts after sunset and the entire process lasts about 2 hours. Special varieties such as tropical water lilies can bloom at night, and temperature control can extend the opening time of a single flower to 72 hours. Seasonal change characteristics In the natural environment, the flowering period is concentrated from May to August, and greenhouse cultivation can be extended to October. The annual flowering volume of a single plant can reach 30-50, and new flower buds can be stimulated to differentiate by removing residual flowers. Records show that continuously maintaining an environment with a water temperature of 28 ° C and an air humidity of 70% can increase the flowering frequency by 40%.
Mastering the ecological habits and growth laws of water lilies can not only achieve precise control of flowers, but also create waterscape wonders that continue to bloom. It is recommended to establish a maintenance log combined with phenology observation, and optimize management plans through data recording, so that water lily blooms become the most moving ecological picture in the courtyard.
