The correct method for watering peony Peony growth characteristics and watering principles As a typical fleshy root plant, peony has strict requirements for water management. Its root system has the function of storing water, which not only requires sufficient water to maintain growth, but also is afraid of suffocation caused by stagnant water. The principle of "dry through and irrigate through" summarized by flower farmers over the past generations is the best practice based on the biological characteristics of peonies that are "drought-tolerant and waterlogging." Seasonal watering grading management Quantitative irrigation is used for 3 days/time during the spring germination period, combined with 0.5% potassium dihydrogen phosphate foliar spraying; the flower bud expansion period is increased to 2 days/time, and the air humidity needs to be maintained at 60%-70%; In summer, the high temperature is implemented in the morning and evening, and the leaves are sprayed with water to cool down at noon; water is controlled to promote lignification in autumn, and the soil is kept in a slightly dry state during the winter hibernation period. Early symptoms of over-watering warning signals identify the edges of new leaves, water-stained spots on old leaves, and softening at the base of petiole. At this time, the soil EC value is usually lower than 0.5ms/cm, indicating serious nutrient loss. A 20% drop in plant transpiration rate should be alerted. Severe water accumulation shows that after 48 hours of continuous water accumulation, the roots begin to brown and rot, releasing ethylene gas to accelerate aging. Systematic wilting occurs on the above-ground parts, flower bud differentiation is blocked, and in severe cases, the entire plant falls. Anatomical observation showed mucus blockage of vascular bundles. Emergency response and long-term prevention and control Short-term rescue measures Potted plants immediately implemented the "three-level relief method": tilting the basin to drain water → bamboo sticks loosen soil to ventilate → fan assisted evaporation. Radial drainage ditches were excavated for ground-grown peonies, vermiculite/perlite were added to improve the soil structure, and 3000 times hymoxazole solution was used to irrigate roots for disinfection. Long-term maintenance strategy establishes a "123 watering detection system": 1 knuckle depth soil inspection method, 2-day observation period, and comprehensive judgment of 3 indicators (leaf color, soil temperature, weather). It is recommended to configure a soil moisture monitor to control the water content within the ideal range of 18%-22%. Scientific maintenance achieves national beauty and fragrance By accurately grasping the "alternating dry and wet" water demand law of peonies and combining modern monitoring technology to optimize traditional experience, it can not only avoid the common misunderstanding of "watering to death", but also give full play to its "graceful and luxurious" ornamental characteristics. It is recommended that flower lovers establish a watering log to record each irrigation time, amount of water and plant response, and gradually form a personalized maintenance plan.
