Cultivation methods and precautions for water mint
Water mint with a fresh luster on its moist leaves is the preferred hydroponics plant by many gardening enthusiasts. However, during the maintenance process, novices often cause yellowing of leaves due to improper humidity control, or the growth of plants is affected due to improper light management. This article analyzes how to create an ecological environment suitable for the growth of water mint through six key dimensions. The three-factor matrix ratio plan for environmental control uses river sand and humus soil mixed in a ratio of 3:2, and 10% perlite is added to enhance air permeability. Adding pine needle soil to the surface every season can maintain the soil slightly acidic, and the pH value is recommended to be controlled between 5.8 and 6.5. Photoperiod management receives full sunshine in spring and winter, and uses a double sunshade net to filter 50% of direct light in summer. The smart fill light supplements 450nm blue light for 2 hours every day to promote menthol synthesis. Temperature and humidity balance is equipped with a temperature and humidity meter for real-time monitoring, and temperature fluctuations need to be controlled within the range of ±3℃. Use an ultrasonic humidifier to maintain the air humidity of 65%-75%, and cooperate with the bottom dipping basin method to keep the substrate moist. Daily maintenance points Gradient watering method Implement the "three-look watering method" during the growth period: look at the leaf tips (replenish water when slightly curling), look at the soil surface (watered thoroughly when turning white), and look at the seasons (3 days in spring and autumn, 1 in the morning and evening in summer). Use a long-spout pot to slowly inject water along the basin wall. Nutrient supply strategy Apply nitrogen, phosphorus and potassium 20-10-20 water-soluble fertilizers from March to September, and root irrigation every 10 days. Add seaweed foliar fertilizer every month and use EM bacterial solution to improve the rhizosphere environment. Advanced Cultivation Skills Amphibious cultivation sets up a water level control system to keep 1/3 of the roots submerged. Use ceramsite planting baskets to realize the water-soil transition zone, which not only ensures water absorption but also avoids root rot. The intelligent monitoring system is equipped with a soil EC value detector, and the automatic leaching program is started when the salt concentration exceeds 1.6ms/cm. Linkage light sensors realize intelligent light filling and improve maintenance accuracy.
Through precise control of temperature, light, soil and water, and modern monitoring methods, the thickness of water mint leaves can be increased by 30%, and the concentration of aroma substances can be increased by 45%. Regular rotation of placement and substrate renewal every six months can keep the plants growing vigorously.
