How much water is appropriate to raise lotus flowers
As a representative of aquatic plants, the water management of lotus flowers is directly related to their growth status. Reasonable water level control not only promotes root development, but also avoids common problems such as leaf rot. This article will systematically analyze the golden rule of lotus hydroponics from container selection to seasonal maintenance. The ratio of container size to water level is recommended for small containers with water volume of less than 30cm. The "two-finger rule" is recommended: after adding culture soil, keep the water surface about 5 cm away from the soil surface (two-finger width). This distance not only prevents the floating leaves from being submerged, but also ensures that the new standing leaves stretch normally. Pay attention to selecting wide-mouthed shallow basins and avoid using deep-barrel containers. Water injection techniques for large water tanks in courtyard water tanks should follow the "three-step water injection method": initially, water is poured to 15cm to activate the lotus root, add to 30cm after the new leaves are unfolded, and maintain 50-80cm at full flowering stage. Pay special attention to injecting slowly along the cylinder wall during water injection to avoid impacting the sediment. It is recommended to configure a transparent water level gauge for real-time monitoring. The water body replacement cycle, the core element of water quality maintenance, replaces 1/3 of the water body every 10 days in spring and summer, and extends to 20 days in autumn and winter. Use tap water that has been dried for 2 days, and the temperature difference between the water temperature and the original water body shall not exceed 3℃. Reserve the bottom 10cm of old water to maintain microbial balance when changing water. The water quality purification plan uses 5-8 medaka fish to build an ecological cycle, and combines them with aquatic plants such as copperweed to absorb rich nutrients. When algae appear, you can hang cotton cloth bags to pack activated carbon and replace it once a month. Guidelines for seasonal water level regulation: Maintain 15cm shallow water to promote growth during spring germination period, deepen to 50cm during summer high temperature period to prevent burns, drop to 30cm in autumn to promote lotus root expansion, and retain 10cm ice protective layer in winter. The northern region needs to cooperate with mobile containers to adjust the water temperature.
Through precise water level control and dynamic adjustment, combined with scientific water quality management, lotus flowers can be in the best viewing state. It is recommended to record a water level log and optimize the maintenance plan based on the plant response so that the beauty of aquatic life can last in the courtyard.
