Do chrysanthemums like water?
As one of the top ten famous traditional flowers in China, chrysanthemums are favored by gardening enthusiasts for their rich varieties and elegant attitude. Among the many maintenance elements, watering management directly affects the growth trend and flowering quality of chrysanthemums. This paper will systematically analyze the special water needs of chrysanthemums based on plant physiological characteristics and provide scientific and feasible watering plans. Analysis of the water demand characteristics of chrysanthemum. The physiological characteristics of preferring moisture and avoiding water accumulation. The root system of chrysanthemum is a shallow fibrous root system, which has the dual characteristics of preferring moisture and fearing waterlogging. During the growing period, the soil moisture needs to be maintained between 60-70%, and water needs to be replenished when the drying depth of the topsoil does not exceed 2 cm. However, too high the groundwater table will lead to hypoxia in the roots, and root rot may be caused if water accumulates for more than 24 hours. The harm of water imbalance shows that the edge of the leaves of water-deficient plants will appear scorched and curled, and the development of flower buds will stagnate; excessive watering will show that new leaves will become yellowed and the base of stems will soften. By observing the condition of the base leaves of the plant, it is possible to judge in time whether the water content (G-Y) is suitable. Detailed explanation of scientific watering methods for chrysanthemums. The water quality optimization plan recommends using slightly acidic soft water with a pH value of 6.0-6.5. The best choice is to let rainwater stand for 24 hours after collection. Tap water needs to be dried for more than 3 days to eliminate chlorine and increase the oxygen content. Regular addition of 0.1% humic acid solution (every 3 watering times) can improve soil structure. The seasonal watering rhythm is controlled for 2-3 days per time in spring and autumn, once in the morning and evening every day in summer (avoid noon), and extended to 5-7 days per time in winter. The amount of water needs to be increased by 20% during the budding period, and the water supply needs to be reduced by 30% after flowering. It is recommended to combine the adjustment of the weather warning system. Water should be suspended and drainage should be strengthened for continuous rainy days. Advanced watering techniques use the dipping basin method to ensure that the deep soil is moist, and each soak should not exceed 15 minutes. Combined with covering a 2 cm thick pine scale substrate, water evaporation can be effectively reduced. The use of intelligent humidity monitors can accurately control soil moisture content within an ideal range.
By establishing a scientific watering system, coupled with regular loosening of soil and nutrient management, the chrysanthemum plant type can be made more compact and the flower diameter can be increased by 15-20%. Keep in mind the basic principle of "seeing wet when you see dry" and dynamically adjust according to the growth stage of the plant, you can cultivate healthy and luxuriant chrysanthemum plants.
